  • Key Factors Impacting Information Quality: An Empirical Study of Thailands Healthcare Sector   Order a copy of this article
    by Intiraporn Mulasastra, Donyaprueth Krairit 
    Abstract: Quality of information produced by information systems is important to organizations, affecting all aspects of business from operations to strategic management. Few empirical studies have examined the factors influencing IQ using quantitative methods. By reviewing the extensive literature in the information systems (IS) and IQ research areas, this study developed an IQ determinant model and measurement instruments for empirically investigating factors that influence IQ at the organizational level. Our model consists of five IQ determinants: IQ control, IS support, system usefulness, IQ leadership, and IQ education and training. We conducted reliability and validity tests by using data collected from 345 public hospitals in Thailand. Hypotheses were tested using structural equation modeling. The results indicate that other than IS support and system usefulness, IQ control (IQ assessment, root causes analysis, and IQ improvement) impact IQ. Hence, Thai public hospitals should institutionalize IQ control similar to quality control in a manufacturing context.

  • Selecting Appropriate Operations Strategy Using Project Management Concepts: An Economic Analysis Approach   Order a copy of this article
    by Mohaddeseh Yaghtin, Mehdi Abbasi 
    Abstract: Having an effective operations strategy (OS) is a key element in protecting competitive capabilities of any company. OS supports the business strategy and should be accurately selected in a way that the organization can be positioned among the competitors. The main objective of this study is to provide valuable insights for project managers to select the most appropriate OS for their enterprise using economic analysis approach. We propose a seven-step algorithm which makes the decision-makers able to make an optimum decision for organizations OS selection on the basis of economic analysis of OS alternatives. This is the first study which presents such an OS selection framework and incorporates project management and OS contents. First we consider each OS alternative as a program (a group of projects) and define some group of projects for actions required in intersections of OS matrix related to each program. Then, by determining the dependencies among the projects of each program as well as providing some information about the projects, we can estimate cash flows of programs. Thus, we can financially evaluate the programs and select the most profitable and appropriate OS. The presented algorithm assists the managers to apply the most financially effective OS for their company. The validity of the algorithm is demonstrated through conducting a case study.

  • Measuring Efficiency in US Teaching Hospitals Associated with Quality Variables   Order a copy of this article
    by Jeong Hoon Choi, Dong-hyun Oh 
    Abstract: This research compares the efficiency of US teaching and non-teaching hospitals as estimated by using Data Envelopment Analysis. Labour costs, capital costs and other operating expenses are employed as input variables. The research models are divided into two main cases based on different sets of outputs. In both cases, teaching hospitals show higher efficiency scores than non-teaching hospitals. For-profit hospitals show higher efficiency scores than not-for-profit or governmental hospitals. With regard to the size, larger hospitals are associated with higher efficiency scores. Regional variations are detected, but they seem to fade in comparing some regions. This paper addresses the economically important question of what explains heterogeneity in production functions across hospitals by measuring the efficiency of hospitals, including quality variables. The inclusion of quality metrics in efficiency estimates represents an improvement over similar existing studies, since patient outcomes are key to considering welfare implications in the healthcare sector.
    Keywords: Data envelopment analysis (DEA); hospital efficiency; quality indicators; healthcare industry.

  • The live sheep export supply chain: When operational and societal complexities collide   Order a copy of this article
    by Elizabeth Jackson, David Adamson 
    Abstract: This paper takes a supply chain perspective on the business systems involved in the trade of live sheep from Australia to the Middle East. Live export supply chains are complex as they must encompass efficiency, maintenance of quality and adhere to international animal welfare protocols. This paper explores the consequences resulting from business systems failure, based on a case study from 2012 when protocols in the international trade of live sheep were compromised. Key themes to emerge from the case study relate to supply chain control and resilience, the moral obligations of governments to manage societal exposure to unsafe food and the management of unscrupulous operators in the food supply chain. The originality of this work lies in its consideration of live cargo and the challenges of unforeseen circumstances in managing the physical distribution of live animals transported by sea.
    Keywords: resilient supply chains; food safety; business communications.

  • Competitive strategy of family businesses through CSV - case study of a family business in Mie Prefecture, Japan   Order a copy of this article
    by Keiko Nishioka, Kiminori Gemba 
    Abstract: Many companies around the world, are family businesses and are the main drivers of the economy. For any revitalization of local communities, the innovation of regional companies is indispensable and if such innovation is realized through regional partnerships, it will become the best possible scenario by which both the society and businesses will prosper. Michael E. Porter has proposed the concept of CSV (creating shared value) and pointed out the importance of sharing values with the regional community. This paper proposes a hypothesis in which CSV, which is important for business management, can also become a source of competitive advantage for companies and analyzes the strategic management of a family business in Mie prefecture. Through detailed case studies, the paper demonstrates that CSV can become an effective competitive strategy for family business and also clarifies conditions for CSV to generate sources of competitive advantage.

  • Linking CRM to Customer-Oriented Behavior through Service Climate Perceptions   Order a copy of this article
    by Mei-Ling Wang 
    Abstract: Integrating the capability view of customer relationship management (CRM) with service climate research, this present study developed a conceptual two-level model that links CRM to customer-oriented behavior through service climate in service organizations. Data from 629 customers involving 141 bank consultants of retail banks in Taiwan was collected via a questionnaire and analyzed using hierarchical linear modeling. The results revealed that CRM was related to service climate perceptions, which, in turn, positively predicted customer-oriented behavior. In addition, the relationship between CRM and customer-oriented behavior was mediated by service climate perceptions. Both theoretical and practical implications are discussed as well as future research directions.

  • Customer participation in business ecosystems: An integrated approach of system dynamics and fuzzy sets   Order a copy of this article
    by Azizbek Marakhimov, Jaehun Joo, Jaegeol Yim 
    Abstract: Today, customers are not only consuming products and services but also actively participating in creating value. However, there is little research on customer participation in business ecosystems. As such, effects of customer participation in business ecosystems remain under-researched. The purpose of this study is to measure the effects of customer participation on business ecosystem health. This study analyzes the effects of customer participation by proposing an experimental framework that combines system dynamics modeling and fuzzy sets. The study identifies and simulates four types of business ecosystems (open customer-intensive, modest, partner-collaborated, and vertically controlled). The simulation results suggest that customer participation positively influences business ecosystem leaders (keystone) financial performance, innovation capability, and the business ecosystems health. The simulation results show that (a) customer participation in production in operations, design, delivery, and sales positively influences a keystones revenue and business ecosystem health, and (b) customer participation in promotion and idea generation increases a keystones innovation capability. Furthermore, the results show that the effect of customer participation varies across the four types of business ecosystems. This study offers important theoretical and practical implications on four types of business ecosystems. They help practitioners develop better strategies to involve customers into co-creation and enhance the health of the business ecosystem.
    Keywords: Business ecosystems; Business ecosystem health; Customer participation; Co-creation; Sustainability; System dynamics; Fuzzy logic.

  • Selection of a Faculty Member in Academia: a Case for Verbal Decision Analysis   Order a copy of this article
    by Helen M. Moshkovich, Alexander Mechitov 
    Abstract: Personnel selection problem is often viewed as a multi criteria problem and there are many examples when different multi criteria techniques support the process. The multi criteria approach was used in several studies of faculty selection in academia but not many recognized that there were peculiarities in the selection process. Most studies concentrated on rank ordering of a small number of finalists while one of the main tasks of the search committee in academia is to select a smaller number of candidates from a possibly large pool of applicants for a more thorough review. In our paper we propose a three-step approach to the problem and recommend Verbal Decision Analysis (VDA) as a tool. Using a VDA method provides a reliable preference elicitation process and the decision rules are easy to understand and explain. Free tool ORCON_Z helps with the practical application. The proposed procedure was well received by the participants and provided valuable information during the selection process.

  • Importance-Performance Analysis of Service Quality Dimensions for the Bangladeshi Hotel Industry   Order a copy of this article
    by Mahbubar Rahman, Rafikul Islam 
    Abstract: In global competitive markets, hoteliers are looking to satisfy guests for repeat customers. Achieving satisfied guests is not an easy task. This study evaluates the service quality of Bangladeshi hotels using gap analysis, SERVQUAL and importance-performance analysis (IPA). The results showed that hotel guests satisfaction regarding service attributes are lower than the importance assigned to the measurement attributes. The widest gap was found in staff response and additional amenities, especially the commitment of hotel staff towards their guests. Also, the IPA grid showed that eight services attributes fell into the concentrate here quadrant. This means that hotel management should take immediate action on these attributes for the betterment of the industry.

  • The value of inventory and the direction of the supply chain bullwhip effect   Order a copy of this article
    by Sima Fortsch 
    Abstract: The bullwhip effect (BWE) is the amplification of demand variability in a supply chain. The traditional view has this effect move horizontally upstream through the supply chain, while the reverse view has this effect move downstream (e.g., from manufacturing toward retail). The bullwhip effect can be quite costly for industry and society as a whole; hence, many researchers have been motivated to study causes of the bullwhip effect to manage, reduce, or eliminate it. This study is an empirical investigation of the supply chain bullwhip effect in which a three-stage supply chain is examined using monthly industry-level data from the U.S. Census Bureau (from 1992 through 2011). Of specific interest is the direction of the bullwhip effect and whether the effect is influenced by the value of inventory and inventory to sales ratios. Two sets of time series regression equations are used to detect the bullwhip effect and its direction in the supply chain. Empirical evidence is found suggesting the bullwhip effect of the supply chain member is influenced by the BWE of the other members, as well as the values of inventory and inventory to sales ratios of own member and other members of supply chain. In addition, there is evidence that the direction of the bullwhip effect is not influenced by the members horizontal positions in the network. It is also shown that the wholesale bullwhip effect exhibits heteroscedastic and nonstationary behavior; thus, making it difficult to predict the BWE of this member over a long-horizon time period. For the manufacturing and retail industries, however, BWE could be predicted.
    Keywords: inventory; bullwhip effect; reverse bullwhip effect; econometrics; regression; time series.

  • Developing Models of DOE and Simulation to Maximize output of Tomato Concentrated Pulp processing Unit   Order a copy of this article
    by C.S. Chethan Kumar, N.V.R.Naidu Naidu, Rajeshwar S. Kadadevaramath 
    Abstract: In developing country like India agriculture is the main stay of the economy. Agricultural industries and related activities can account for a considerable proportion of their output. Due to insufficient demand, weak infrastructure, poor transportation and perishable nature of the crops, the grower sustains substantial losses. Even established fruit and vegetable canning factories or small/medium scale processing centers suffer huge loss due to erratic supplies. The main objective of fruit and vegetable processing is to supply wholesome, safe, nutritious and acceptable food to consumers throughout the year. Fruit and vegetable processing projects also aim to replace imported products like squash, jams, tomato sauces, pickles, etc., besides earning foreign exchange by exporting finished or semi-processed products. For example, a particular variety of fruit which may be excellent to eat fresh is not necessarily good for processing. Processing requires frequent handling, high temperature and pressure. Many of the ordinary varieties of tomatoes, for instance, are not suitable for making paste or other processed products. Simulation was carried out for the updated model for a period of ten days with five replications. From the results obtained from the DOE, noises in the factors (Steam losses, Minor stoppages) were reduced by implementing the mentioned techniques. The runs are randomized using MINITAB software. A cost matrix was made to create a tradeoff between all factors that were affecting the performance. This resulted in the increase of throughput rate in the real scenario. This research project demonstrates the practical application of Design of Experiments(DOE) showing how it can bring real breakthroughs in productivity of fruit(Tomato) processing industry. This research work was carried out with the objective of designing new decision making method for controlling the production and material flow in the process industry

  • WHAT ARE E-COMMERCE POSSIBLE CHALLENGES IN DEVELOPING COUNTRIES: A CASE STUDY OF NIGERIA   Order a copy of this article
    by Habib Ullah Khan, STELLAMARIS UWEMI 
    Abstract: The overarching goal to achieve the vision of Nigeria (NV2020) cannot be realized without the synchronized effort of all the sectors. To help the country and policy makers to identify the hurdles in attaining these lofty goals, the present work tried to bring the views of customers and operators of e-commerce into limelight. The study is primary data based and the data is collected using a questionnaire that is drafted separately for both the parties, operators and customers of Nigeria. Because of the limitations, the study could collect the data from ten operators and 200 customers and advanced statistical techniques are exercised. The data collected from the customers revealed that though they are interested in e-commerce operations (like online trading), majority are unable to complete the tasks successfully. This is because of the bottlenecks being encountered with respect to various sectors. In addition, the correlation analysis proved that the challenges of e-commerce have majority bearing on the economy of the country. On the whole, the study not only provided inputs to the policy makers, but also explained the operators of e-commerce about the capabilities, requirements and problems of the customers in performing successful e-commerce transactions.

    by Hossein Mansoori, Ali Shaemi Barzoki, Mohammad Hossein Moshref Javadi, Masoud Kianpour 
    Abstract: In human resource management (HRM) system, there are many factors that can affect the organizational empowerment. Human resource practices are some of these important factors, which were mainly studied at individual level and were rarely explored at the organizational level. Focusing on power industry in Iran, the current study sought to develop and test an organizational empowerment model based on human resource practices. A mixed methods approach was utilized, including a grounded theory study that was followed by a quantitative phase. The qualitative phase was conducted to develop an organizational empowerment model based on human resource practices.The hypotheses developed in the qualitative phase were tested through quantitative phase, including structural equation modeling.The results revealed that views and attitudes towards human resources as causal factors had significant effects on human resource practices; and human resource practices, contextual factors, as well as intervening variables had significant impacts on organizational empowerment strategies.

  • Towards the Verification of Cyber-Physical Processes based on Time and Physical Properties   Order a copy of this article
    by Imen Graja, Slim Kallel, Nawal Guermouche, Ahmed Hadj Kacem 
    Abstract: Cyber-physical systems (CPS) enable the development of complex real-world applications through the integration of computing and non-computing elements. At-design time, a cyber-physical process is a set of cyber and physical activities performed to accomplish a common goal in a given amount of time. The collaboration between the cyber-physical processes, through exchanging messages and objects, describes the behavior of networked cyber-physical systems (NCPS). CPS have time-related and physical properties, which are crucial to the correctness of their execution. However, when we specify the collaboration between multiple processes, some combination of their corresponding properties can be conflicting. This conflict renders the participating cyber-physical processes incompatible. We observe two types of problems: implicit time-related, and physical-related incompatibilities. In this paper, we propose a novel approach to verify the compatibility of collaborative cyber-physical processes with time-related and physical properties. In order to accomplish our verification, we first define a set of constraints that specify the structural, time-related, physical and synchronization properties. Next, based on the defined constraints, we automatically transform the NCPS model into a constraint satisfaction model. Finally, we analyze the generated constraint satisfaction model to check its consistency. We demonstrate the applicability of our approach through a case study and discuss its effectiveness in modeling and verifying the cyber-physical processes.

  • Prioritising Disclosures of Information in Analyst Reports using the Analytic Hierarchy Process: Evidence from Malaysia   Order a copy of this article
    by Hassanudin Mohd Thas Thaker, Azhar Mohamad 
    Abstract: This paper aims to document investor priority of information disclosed in analyst reports which has not been extensively researched in the context of Malaysia. For the purpose of analysis, this study uses primary data via a survey method. The data is analysed using a versatile multi-criteria decision-making approach, known as the Analytic Hierarchy Process (AHP). Findings reveal that investors place higher priority towards valuation in making an investment decision, followed by earnings summary, share performance, forecast revision, share information, financial indicators, segmental analysis, and scorecard in their use of the analyst report. The study is the first attempt to illustrate the priority of information disclosure in analyst reports given by investors when making an investment decision. Since this area of analyst recommendation is untapped in the context of Malaysia, the result of this study is expected to enrich the existing literature available in the field of analyst reports.
    Keywords: Analyst report; Analytical Hierarchy Process; Malaysia.

  • Assessing Service Quality using Fuzzy Numbers and TOPSIS: An application to Self-Contained and Serviced Apartments   Order a copy of this article
    by Juan Carlos Martín, Cira Mendoza, Concepción Román 
    Abstract: This research paper proposes a methodological framework to assess the service quality (SQ) of self-contained and serviced apartments (SCSAs). The study is based on 2753 surveys administered in a SCSA resort located in the south of Gran Canaria Island. SQ is based on a questionnaire that contains a list of 48 attributes. The answers format is based on a 4-facial expressions scale that cannot be easily transformed in a numeric scale. Thus, the ambiguity and possible biased analysis has partly overcome applying the fundaments of the Fuzzy Set Theory. TOPSIS approach is then employed to obtain a synthetic SQ indicator. Finally, an observation-attribute relative performance analysis is developed to identify the operational areas that need improvement or can keep up the good work. The findings of this study may assist managers and policy planners with important insights about the attributes that tourists value more.

  • Managing University Rank and Tenure Decisions Using a Multi-criteria Decision-Making Approach   Order a copy of this article
    by Enrique Mu, Cynthia Nicola 
    Abstract: Faculty evaluation in academia is a serious concern for higher-education administrators. This study develops a model for rank and tenure (R&T) decisions using an Analytic Hierarchy Process (AHP) multi-criteria decision-making (MCDM) approach. Literature review suggests most R&T evaluations are rather subjective in many institutions. A case method approach is used for the development of a model and demonstration of its use. The proposed evaluation model provides objectivity, transparency and customization for R&T committee decisions in higher-education institutions.

  • Hedonic Preference for Technological Devices Justified by Utilitarian Application   Order a copy of this article
    by Emílio José M. Arruda-Filho 
    Abstract: This study analyses consumer behaviour for bundled mobile phones, and tests the perception that integrated products have higher hedonic, rather than utilitarian, value. The study covers a variety of scenarios based on brand, price, and preference (hedonic or utilitarian) in the selection of mobile telecommunications devices. Two studies are developed on two specific themes: benchmarking of hedonic and utilitarian values according to consumers current mobile phones, and hypotheses testing of consumer preferences related to hedonism/utilitarianism under the conditions of brand, price, and mobile characteristics (kind of convergence) proposed. This study enhances understanding of consumers preferences and market tendencies according to their values related to hedonic and utilitarian characteristics converged in mobile devices. Thus, it has academic implications related to the theory of technology convergence according to the characteristics of new products that can lead to a combined hedonic, social, and utilitarian values perception. In terms of practical implications, the findings enhance comprehension for enterprises regarding which features/attributes, according to significance, are most closely related to the various scenarios that consumer are exposed to.
    Keywords: hedonic value; utilitarian value; technology preference; bundle products.

  • A multicriteria approach to the prioritization of stock investment funds   Order a copy of this article
    by Frederico Silva Valentim Sallum, Luiz Flavio Autran Monteiro Gomes, Maria Augusta Soares Machado 
    Abstract: In this paper the performance of 9 stock investment funds present in the Brazilian market is analyzed for the period from May 2015 to April 2017. The key objective is to establish 4 ways to rank the funds under analysis taking into account future financial contributions and investors with different points of view. Initially the TOPSIS method is applied considering the months as criteria and this leads to producing a degree of power for each fund. By using returns of the funds the accumulated rate and volatility are determined for each fund in 2 periods. As a next step the degree of influence between funds is computed and the WINGS method is applied. WINGS leads to 4 prioritizations of the funds in order to fit to the different points of views of financial experts.
    Keywords: Prioritization of stock investment funds; Performance of stock investment funds; Multicriteria analysis; TOPSIS method; WINGS method.

  • The Impact of Governmental policy on the Relationship between IT systems inputs and Business Performance: A Comparison of Large Corporations and SMEs in Taiwan   Order a copy of this article
    by Hsin-Pin Fu, Hsiaoping Yeh, Wen-Chin Yeh, Tzu-Ling Chien 
    Abstract: To rapidly adapt to global competition, manufacturers business models have shifted from a company focus to a focus on the whole supply chain. The Industry Global E-Logistics Diffusion Plan has provided funds for manufacturers to establish their IT-based logistics systems. However, the performance of such establishments has not yet been evaluated, particularly under the influences of government policy. This study investigated the impacts of successful IT-based logistics systems and partnership in the supply chain on business performance moderated by government policy and organizational effects. The findings show that, for both large corporations and small-and-medium companies, their IT inputs and partnership would positive affect business performance. Government policy shows its moderating effect on IT inputs boosting up business performance. Yet, particularly for large corporations, organizational factors can also moderate the causal relationship between IT inputs and business performance.

  • A Fuzzy Optimization Approach for Software Reliability Estimation   Order a copy of this article
    by Boby John, Rajeshwar Kadadevaramath, Immanuel Edinbarough 
    Abstract: Many organizations today utilize information technology to gain competitive advantage. As a result, Information Technology industry has witnessed extraordinary growth. Many times the software companies compromise on software testing to avoid cost or schedule overrun. This might make the software unreliable. Hence it is imperative for the software firms to estimate the reliability of the software and ensure that their products are reliable. A wide range of models is available for reliability prediction. But there isn\'t a single model suitable for all software products. Hence it is necessary to identify the best-suited software reliability model for every software product. Unfortunately, the best fit model identification depends on the performance characteristics used for selecting the model. In this paper, the authors suggest a fuzzy optimization methodology to choose the best software reliability model based on multiple performance characteristics. Two case studies demonstrating the proposed methodology are also presented in the paper.
    Keywords: non-homogeneous Poisson process; software reliability growth models; fuzzy optimization methodology; multiple response optimization.
