Title of the Paper: Investigation of Flexible Multi-Mode Harmonic Vibration for the
Automatic Washing Process
DOWNLOAD FULL PDF
Authors: Jian-Long Kuo, Tsung-Yu Wang
Abstract: This paper will discuss multi-mode vibration for the vibration motor in the washing process.
Sinusoidal vibration modes for the speed servo command will be carefully designed for the flexible control.
Different kinds of operating modes for the possible automatic process control are provided. Three basic and
five extended vibration modes for different operation are proposed. Simulation and experimental results will be
compared to verify the formulation. This will make the washing process more flexible, in order to easily
configure the servo control. Differing from the conventional approach to regulate the blade angle for the
vibration motor mechanically, the multi-mode vibration developed by the software approach is successfully
proposed. It is easy for the washing process to be regulated electrically instead of mechanical operating only. It
is believed that this paper will be beneficial to the automatic washing process application for the washing
machine.

Authors: Bashar S. El-Khasawneh
Abstract: This paper discusses the role of educational institutions in promoting entrepreneurship and risk taking, particularly in conservative communities and cultures. Two main topics are discussed in this paper. The first is tailoring the academic program and all activities supporting it to serve the goal of promoting entrepreneurship. The second topic is to construct a particular form of incubators suitable for emerging economies which is financial resources bound. These incubators serve multiple functions, therefore, in addition to the traditional role of incubating potential-businesses; the other roles are serving as a training site for business-related and soft skills topics for students and serving as an expert house for the industry. This would promote the universities’ role in serving and prospering their communities impacting positively the emerging economy. Efforts related to these topics by a Jordanian University will be discussed as the case study. Keywords:

Authors: Chang-rui Yu, Yan Luo
Abstract: Firstly, this paper introduces the concept of problem identification that is an early stage of decision-making process.
The paper proposes that, as a subjective process, problem identification is mainly influenced by people’s cognition capability.
Actually, the identification process is an evaluation process whose final aim is to evaluate the gap between the reality and the
expected condition. Then, according to this feature, the paper establishes a gray incidence degree model and a satisfaction degree
model based on response value. Further, the paper validates the models through an example.

Authors: Behnam Fahimnia, Lee Luong, Romeo Marian
Abstract: Implementation of a supply-chain (SC) system has crucial impacts on a company's financial
performance. Overall performance of a SC network is influenced significantly by the decisions taken in its
production-distribution plan which integrates the decisions in production, transport and warehousing as well as
inventory management. Thus, one key issue in the current research area of performance evaluation of SC
network is the optimization of production-distribution plan considering its actual complexity. This paper
presents a comprehensive review and analysis on the proposed production-distribution models with special
emphasis placed on the optimization and simulation studies. A summary table will be established to describe
the main characteristics of the selected models outlining the strengths, weaknesses and the level of complexity
for each study. Finally, by providing suggestions for improvements, further works in the area will be addressed.

Authors: Huaqing Wang and Peng Chen
Abstract: This paper presents a condition diagnosis method for a blower system using the rough sets, and a
fuzzy neural network to detect faults and distinguish fault types. In order to solve the ambiguous problem
between the symptoms and the fault types, the diagnosis knowledge for the training of the neural network is
acquired by using the rough sets. The fuzzy neural network realized by partially-linearized neural network
(PNN), which can automatically distinguish the faults. The PNN can quickly converge when learning, and can
quickly and high-accurately distinguish fault types on the basis of the probability distributions of the machine
conditions when diagnosing. The non-dimensional symptom parameters are also defined in frequency domain,
and those parameters are processed by rough sets to sensitively diagnose machinery conditions. Practical
examples of the diagnosis for a blower system are shown in order to verify the efficiency of the method
proposed in this paper. Keywords:

Title of the Paper: Discovering Tacit Knowledge in Business Decision Making

Authors: Nikola Vlahovic
Abstract: In dynamic and globalized business environment the only certain source of lasting competitive
advantage of companies is knowledge. By maintaining and acquiring relevant knowledge through the use of
knowledge management systems businesses are sustaining their competitive advantage over other players in the
market. In this sense one of the most important activities is decision making. Decision making process must take
into account all of the relevant knowledge in order to reach optimal decision, specifically knowledge that is not
available to other competitors – tacit knowledge. In this paper we propose an information-driven approach that can
be used to make model of knowledge that management executives and experts posses. The model can reveal new
relations that have not been explicitly articulated during the knowledge engineering process. In the case study that
will be described in this paper, knowledge was used to determine the criteria for evaluation of various decision
options during a selection of IT Security solution for the organisation. The information-driven approach is based
on the modified ID3 algorithm implemented in the DoctuS expert system shell. Results of the developed
knowledge model is presented and discussed. Keywords:

Title of the Paper: Comparing the aggregation methods in the analytic hierarchy process when uniform distribution
DOWNLOAD FULL PDF
Authors: Wen-Hsiang Wu, Chang-tzu Chiang, Chin-tsai Lin
Abstract: The Analytic Hierarchy Process (AHP) is a popular methodology for group decision making. Individual judgments can be aggregated in several ways, with the most effective approach being the aggregation of individual judgments (AIJ) and Individual priorities (AIP). When the judgments are aggregated, regardless of whether AIJ or AIP are used, arithmetic and geometric means are selected by decision makers. Some articles have discussed these two methods and made relevant suggestions. But when they discuses the issue of these, the distribution from judges’ opinion were not considering. This study performed simulation to generate the weights of the judgers, assuming that the opinion are distributed as Uniform distribution and then generated AHP weights using arithmetic and geometric means. Following performing statistical testing for the relative mean square errors between the parameter and estimator based on simulation, the results demonstrated no significant difference. Finally, based on the results of this study, we conclude the following: (1) if number of judges is not large both then both methods are applicable; (2) if number of judges is large then the geometric mean cannot be obtained, and the arithmetic mean is applicable; and (3) when the opinions of judges coincide, the arithmetic mean is applicable.

Title of the Paper: A Hermeneutic Approach to the Process of Information Realizing in the Context of IS
DOWNLOAD FULL PDF
Authors: Sufen Wang, Junkang Feng, Chunmei Lin
Abstract: Existing studies about information in the fields of information systems (IS) seem inadequate and lacking of sufficient depth. We draw on ideas of philosophy and believe that only through exploring the relationship among information, data and meaning from the viewpoint of “which information qua information ‘can be said’”, can the essence of information be engaged with. It seems that the most vital point for furthering theoretical studies is that new meaning is created through specific activities and behaviour of interpretation. We draw on Heidegger and Ricoeur’s interpretivism and systematically analyze the process of meaning attainment in the realizing process of information, and propose a semi-structured model for such a process. We also show how this approach may facilitate the identification of information requirements for information systems development. Keywords:

Authors: Massimo Paolucci, Roberto Revetria, Flavio Tonelli
Abstract: A major problem faced by manufacturing organizations is providing efficient and cost-effective responses to the unpredictable changes taking place in global markets and in supply chains. Sales and Operations Planning helps giving better customer service, lower inventory, shorten customer lead times, stabilized production rates providing top management with a handle on the business and supporting a company to get and keep demand and supply in balance over time. This paper proposes a multi-agent based system that would enable small and medium-size manufacturing organizations to dynamically achieve cost-effective aggregate sales and operations plans in supply chain contexts. The simulation of the agent’s interactions supports planners, in supply chain operations planning, providing multiple scenarios with respect to the balance between supply and demand. This paper presents the main features of the proposed system and it finally discusses the benefits and limitations highlighted by its application in real industrial contexts. Keywords:

Authors: Chao-Hua Chen And Hui-Yu Lee
Abstract: In this study the focus was on comprehending the vital factors that affect the loyalty of international logistics service provider (ILSP) customers, with the aim of providing recommendations for sustainable operations. Empirical analysis was performed to explore the customer loyalty problem in the international logistics market. Data for analysis was collected by questionnaire survey directed at customers of an ILSP headquartered in Taiwan, with branches located around the world. The customer loyalty problem was first tackled by developing a conceptual framework. The structural equation modeling method was then used to do the empirical analysis. Causal hypotheses regarding the loyalty of customers for ILSPs were established based on their special attributes and related research results reported in the literature. Empirical analysis results of this study show that service quality, customer satisfaction and switching cost are all critical to customer loyalty. Of these, customer satisfaction and switching cost both have a positive relationship with customer loyalty; service quality has a positive influence with customer satisfaction, as well as an indirect positive influence with customer loyalty; there is a positive relationship between customer satisfaction and switching cost. Research and managerial implications for practical operations are also discussed. Keywords:

Abstract: Aviation disasters cause huge loss of lives and properties. Any densely populated and economically viable country inevitably faces the challenge of efficiently and effectively responding to such disasters. This study supports in-time reaction to aviation disasters from the medical point of view: transferring patients to available hospitals to maximize their survival time. This study first assumes a large aircraft crash at the airport and many trauma patients generated in a metropolitan area. Second, we propose a multi-objective model of an emergent medical decision system, able to plan optimal patient transfer from one hospital to another according to various trauma situations to maximize survival time. Trauma patients are classified into three types: the emergent type (Red) to the normal type (Green). Each model objective maximizes survival time for each type of patient. Our model is established on the basis of the multi-objective location-allocation model in operational research; furthermore, the Visual Basic for Application (VBA), Lindo, and Geographic Information System (GIS) are successfully integrated to graphically show simulated results. Our multi-objective medical decision system is valuable as radio frequency identification (RFID) technology matures. Integrating our multi-objective GIS and RFID data from patients will optimally utilize medical resources. Keywords:

Authors: Hsien-Ming Chiu and Han-Shuan Huang
Abstract: The Dial-a-Ride Problem (DARP) is a vehicle routing problem faced in arranging Dial-a-Ride services. The DARP has been proven a NP-Hard problem; therefore, most research has used heuristic solution methods to address this issue. The purpose of this study is to evaluate of the application of a Diversity Control Adaptive Genetic Algorithm (DCAGA) and Family Competition Genetic Algorithm (FCGA) on the DARP. This study proposed two solution procedures, which were integrated approach and cluster approach. A series of case studies with different characteristics, such as demand density and demand size, were used to test the solution capability of the proposed algorithms. Based on the results of the case studies, the Diversity Control Adaptive Genetic Algorithm is identified as the best algorithm in solution quality. Overall, the solution of the integrated procedure is better than, those of the two-phase procedure. Keywords:

Authors: Yuh-Jen Cho and Ya-Wen Hsu
Abstract: This paper considers two special methods of operation for the multi-temperature common distribution in the ‘cold-chain’ logistics. The first is that carriers utilize the engine-driven frozen truck divided into three parts to hold goods of different temperatures. The second is that carriers utilize the multi-temperature storage box, found in a general truck, to hold those goods. We transferred the previous operations into two Heterogeneous Multi-temperature Fleet Vehicle Routing Problems, HMFVRP1 and HMFVRP2. A set of 168 instances, created by modifying VRP and VRPTW benchmark instances, is used to compare the performance of HMFVRP1 and HMFVRP2. In addition, real costs and the capacities of different sized trucks are set for these test instances. Then, we also develop a simple heuristic algorithm to solve these HMFVRPs. Computational results present that, in average, HMFVRP2 performs superior to HMFVRP1 in both of vehicle usage cost and travel distance. Such a finding could offer an alternative toward improving the performance and efficiency of the practical multi-temperature common distribution. Keywords:

Authors: Chui-Yen, Chen
Abstract: Both China and Taiwan have already obtained the WTO membership and officially participated in the international trade system. The economic and trade relationship between China and Taiwan should develop by following the rules of international trade development. Due to the high rate of growth of the economic and trade exchange between China and Taiwan, up until now, Taiwan has relied heavily on the mainland for its exports and vice versa. This study is intended to probe the issue. We established forecast models for the cross-strait trade through the methods of grey forecasting, simple regression, and exponential smoothing. In addition, it tests the accuracy of the forecast models through relevant data, and used MAPE and MSE to evaluate the forecast models. The results indicate that for model selection, it is more correct to perform the forecast on trade volume based on the statistical information released by Taiwan Customs. It can be seen from this model, the cross-strait trade volume in 2008 will exceed USD $73,500 million, with imports into Taiwan above USD $36,373 million. It is hoped to understand the cross-strait trade growth trend in the future with the forecast model established by our research institute and thus providing the government or the agencies concerned with reference information for making their cross-strait policies.

Authors: Hiroyuki Kawaguchi and Seiichi Komiya
Abstract: The authors classify licensing application procedures in Japan as factors that comprise procedures
including application documents and attachments, and have developed an application procedure ontology that
defines the reference relationship among each factor at the level of items described or listed in documents. In
addition, a method to derive acceptance or rejection of item transcription in One-stop application procedures as
well as work steps through inference was reviewed by utilizing the application procedure ontology.
Consequently, if specific items in attachments are in the reference relationship with other relevant application
documents, it was found to be possible to make an inference that item transcription is possible through the
mediation of such attachments, by using the reference relationship defined by this application procedure
ontology. By determining the work priority based on the referenced number among instances, visualization of
overall workflow of application work was made possible in regards to the One-stop application combined with
the range selected by an applicant.

Abstract: Rise of ecommerce, which followed by Internet, has created some complexities in most industries.
To overcome the information overload for Internet users, several Recommender Systems (RS) have been
developed. RS is a kind of automated and sophisticated decision support system by monitoring the past actions
of a group of customers to make a recommendation to individual members of the group to mitigate the problem
of vast product and service information. The main issue is adoption and implementation of RS to make it
suitable for society and avoid wasting time, energy and cost. Therefore, we compare several models of
acceptance and introduce the critical and main parameters of a proper acceptance model for the product and
service, which guarantee the result of RS employment. Two independent acceptance models with questionnaire
will be derived for the retail and banking service industry, localized for Iran’s product and service context as a
tool to measure customer’s intention to adopt an RS. To verify the validity of the parameters and selected
models, two questioners are run. The statistical information and numerical result from LISREL presents the
validity of the proposed extended TPB and TAM model for the retail and banking service context, respectively.

Abstract: Over the past years, at an increasing pace, customer satisfaction has been an emphasis in most organization especially those in the service industry. Service quality becomes the major focus on achieving customer satisfy action and, over the long run, customer retention. Responding to the notion, many retailers begin to appreciate Customer Relationship Management (CRM) concept and constantly improve the quality of services that they offered to fulfill the customers expectations and satisfactions. Currently, the practice has also extended to the online retailers, both ‘brick and mortar’ and ‘click and mortar’ companies. The CRM concept has broaden to include online customers and services. This study is undertaken to explore the internet service quality in online service industry, particularly in e-ticketing of transportation service. Web observations were performed to identify the major and significant determinants of quality of internet services. By using electronic CRM (e-CRM) model as reference in observation, it is found that appearance and linkages are two important determinants that should be used when measuring the quality of internet services. Through the findings, a guideline of the transportation websites incorporating important features of e-CRM is developed.

Abstract: Total ultimate energy consumption in Iran was 1033.32 MBOE in 2006, and increased at an average annual rate of 6% in 1996-2006. Household and commercial sector has been the main consumer sector (418.47 MBOE) and the fastest-growing sector (7.2%) that followed by transport (264.65 MBOE; 7%), industry (238.86 MBOE; 5.3%) and Agriculture (37.39 MBOE; 2.1%). Iran’s ultimate energy consumption pattern over the last decades is inefficient and contributes towards the excessive consumption of fossil fuels which produces several quantities of pollutants and green house gases. Low price of energy and high subsidies represent an effective incentive for inefficient energy consumption pattern and accelerate energy consumption and environmental pollutions. The present paper provides a detailed analysis of the ultimate energy consumption in Iran by sectors during the last 10 years. We conclude that energy conservation policies by sectors are necessary in Iran and also the paper includes several suggestions for each sector to reduce energy consumption.

Authors: Mario Spremic, Zlatan Zmirak and Krunoslav Kraljevic
Abstract: In the early days of implementing IT in the business, it was often seen as a technical support function and was typically managed by finance departments. When evolving from technology providers into strategic partners, IT organizations typically follow a three-stage approach: IT infrastructure management, IT service management and IT business value management (IT Governance). As the IT initiatives has become far more than a means of improving efficiency and reducing costs and increasingly account for enabler of business innovation, it still seems that it is less understood business resource. One of reason could be that often there is no systematically way of measuring IT performances and implementing IT Governance practices. In this paper we investigated the practices by which IT can contribute to the business as well as how to measure it. Main objective of this paper is to stress the importance of evolving IT Governance activities. Similarities between corporate governance and IT governance are discussed in further details. On the sample of selected Croatian large companies, the organizational position and the role of IT in the business has been investigated, while specific research interest was to get the clear view of the maturity level of IT usage. We hoped that such approach could be useful when trying to answer the posed research question: what stage of IT maturity level (from technical support to IT Governance) reflects the IT practices in the Croatian large companies?

Abstract: E-government refers to the intensive use of ICT, especially Internet and web, in delivering government information and services to citizens. E-government is defined as ‘utilizing the Internet and the world-wide-web for delivering government information and services to citizens’ (UN & ASPA, 2001). Jaeger (2003) added that, apart from Internet and web, it may also include other ICTs in providing superb governmental information services to the citizens (examples are database, networking, discussion support, automation, tracking, personal identification technologies). Means and Schneider (2000) define e-government as the relationships between governments, their customers and their suppliers by the use of electronic means. In this paper we give a brief review of e-government concept and the models of its implementation worldwide. A comparative analysis of e-government deployment is given and major activities stressed. E-government services and applications may positively affect the development of the Croatian emerging economy, as Croatia, even the EU candidate state, is still a country in transition. The review and discussion of current and future progressive e-government services and their impact on society and economy are given. The case studies results and analysis came up with the conclusion that efficient e-services my positively affect the transparency of various systems in Croatia such as justice, public procurement, health, etc.

It has the ability to target the users anywhere and anytime with personalized and location based instant messages. The businesses utilize these features well to suit their business operations. The amazing features of mobile marketing led the users feel that their personal property got intruded without prior permission thus creates concerns over violation of right to personal privacy. This article using content analysis method analyses the possible violation of right to privacy in mobile advertising. The analysis would seek to know the legality of the mobile marketing practices and the level of protection guaranteed in the legislation. The Laws in European Union Countries, Australia and the United Arab Emirates were analyzed for this purpose. The finding suggests that there are legal provisions on the issue of right to privacy and as long as the businesses adhere to the laws, mobile marketing will remain legal. The European Directives on data protection are very influential and many countries have followed the provisions of the Directives.

Abstract: Considering the demands of knowledge society each organization must became an intelligence
organization. Business Intelligence (BI) helps achieving this goal. The large variety of Business Intelligence
solutions on the market, the difficult process to select one of them and evaluate the impact of the selected
solution on the organization leads to the need of creating a strategy to help organizations chose the best solution
for investment. Taking into account that every organization must spend its money carefully, and every solution
that does not provide a rapid impact on the basic business is not considered a viable solution, the efficiency of
its use must be correctly evaluated and demonstrated based on evaluation criteria, but also through monetary
analyses (more difficult to achieve). We suggest and explain the main steps in order to choose the right solution
and to evaluate it and we present a case study of the integration in Romanian public institutions of a Business
Intelligence solution for acquisitions.

is build to design the economic optimization. A numerical example illustrates the efficiency of the algorithm.

Abstract: The paper presents the most important characteristics of three types of healthcare systems in Europe –
Beveridge, Bismarck and Semaşko systems – and intends to analyse the healthcare system in Romania based on a
comparison with the countries that initiated and are representative for these models (United Kingdom, Germany,
Russia). In order to outline the image of the healthcare system in Romania, we used multiple regression models to
emphasize the impact of economic and social determinants of health on certain indicators. The results of the conducted
analysis showed that the evolution of the Romanian health indicators are not always to be ascribed to the
conventionally thought to be important factors.
Keywords: European healthcare system, Romanian healthcare system, economic analysis, health indicators,

Abstract: Mobile technology is a buzzword of present times and mobile devices are used by almost everybody
in advanced countries. But at the same time most people only make use of a tiny amount of capabilities they can
offer. This contribution focuses on the most current possibilities and potential of mobile devices. We will
concentrate on the possibilities and tools applicable in the process of creating mobile software applications and
ways of integration of mobile clients into information systems.

Title of the Paper: Supply chain manager selection
using a combined multiple intelligences theory and ANP approach

Authors: Yu-Ting Lee
Abstract: Modern supply chain managers are required to possess a set of competencies or multiple
intelligences in order to meet the pressing business challenges. However, although many works have studied
problems in supply chain management, few of those discussed the issue of supply chain manager selection.
Especially, selecting competent supply chain managers is a kind of Mu1tiple Criteria Decision-Making
(MCDM) problem which requires us to consider a large number of complex factors as multiple-criteria.
Many traditional MCDM methods are based on the independence assumption, whereas the Analytic Network
Process (ANP) is a MCDM method which can deal with all kinds of dependences systematically. Since the
ANP has these advantages, this paper proposes a favorable method combining multiple intelligences theory
with ANP approach to help companies that need to select competent supply chain managers. Additionally, an
empirical study is presented to illustrate the application of the proposed method.

Title of the Paper: A hybrid approach to IT project selection

Authors: Wei-Wen Wu
Abstract: Numerous enterprises anticipate that Information Technology (IT) may enhance their competitive
advantage and profitability, and provide them with a competitive edge in meeting the challenges from global
competition. However, there is a critical issue of how to invest in IT judiciously and improve the
performance of organizations successfully. Although several methods have been proposed for selecting
appropriate IT projects, their models use few criteria and lack sufficient information for evaluation. Indeed,
to ensure the alignment of IT investment and strategic needs in the real world, it is necessary to consider a
variety of financial and non-financial factors within the evaluation structure. In order to devise a more useful
way to solve IT project selection problems, this paper combines the decision making trial and evaluation
laboratory (DEMATEL) with the analytic network process (ANP) and the zero-one goal programming
(ZOGP) to propose an effective solution that considers both financial and non-financial factors. Additionally,
an empirical study is presented to illustrate the application of the proposed solution.

Abstract: In recent decade, the business of manufacturing and service organizations alike is strongly
conditioned by unpredictable changes taking place in a global market. The question is how to provide efficient
and cost-effective responses on time. Current systems such as extended enterprise resource planning (EERP)
and supply chain management (SCM) do not provide adequate facilities for addressing this problem. This
paper addresses multiplatform integration as a key factor for designing a novel kind of global enterprise
resource planning (GERP) systems. The main idea is based on merging two separate approaches, i.e integrated
agent-based network models of e-manufacturing systems and supply chains (EERP and SCM simulation
platforms), and a field-based information network of intelligent agents. We examine each approach separately
and give some clues how the merging of both approaches may contribute to the achievement of better
simulation results.
