- Group decision-making processes and group decision quality: moderation of mutual interest
by Aziz Bakay, Jun Huang, Yundong Huang
Abstract: Considering the existence of mutual interest in work groups within organisational context, we investigated three main decision-making processes: Personal task participation, negative socio-emotional behaviour and information domination. To illustrate the relationship between group decision-making processes and decision quality, we developed and tested a process model in which the final group decision quality could be predicted by abovementioned decision-making processes. Testing the moderation effect of mutual interest is considered as focus of study and its implications are discussed. Further expansion of our model involves process satisfaction as an intervening variable. The overall assessment of the group decision-making process was captured in the process satisfaction construct and its association with decision quality was analysed. The findings suggested that our 1st model supported the moderation of mutual interest with one exception. The findings of the 2nd model suggested that satisfaction of the group members about decision processes is strongly associated with decision quality.

- Do characteristics of audit committees and board of directors influence earnings management?
by Jagdish Pathak, Khondkar E. Karim, SangHyun Suh, Ziwen Zhang
Abstract: Earnings management has attracted much attention in this globalised economic environment due to large accounting scandals such as Enron and WorldCom. National governments and other market-regulation institutions are taking measures to restrain earnings management in order to ensure the reliability and transparency of financial reporting. This study explores whether audit committees and boards of directors influence earnings management using the literary review method. The findings show that both discretionary accruals and abnormal accruals are mostly used as dependent variables to detect earnings manipulation estimated by the Jones and modified Jones models. For the most part, evidence from previous literature indicates that the more independent the members of the audit committee and board, the higher the quality of earnings in financial reporting. However, some opposite findings exist.

- Making the recruitment decision for fresh university graduates: a study of employment in an industrial organisation
by Mohammad Hossein Zarei, Kuan Yew Wong
Abstract: Owing to the intense need for educated and talented workforce, especially in developing countries, recruiting fresh university graduates has become an important issue for organisations. However, conventional recruitment and personnel selection methods may be unable to fulfil the task due to some uncertainties and complexities such as lack of past work experience or creeping subjectivity into the recruitment process of fresh graduates. This paper addresses the problem by proposing a two-fold recruitment approach which benefits from human resource personnel selection methods and analytic hierarchy process (AHP). A study of employment for an industrial organisation in Malaysia was conducted and the proposed model was applied. The study has shown the overriding role of university lecturers for the recruitment of fresh graduates. The consistency and validation of the model was examined through experimental procedures based on consistency test and sensitivity analysis.
Keywords: recruitment; employment; fresh graduates; analytic hierarchy process; AHP; validation; rÃ©sumÃ© screening; job analysis; structured interview; manufacturing; industrial; Malaysia.
- Sensitivity analysis on PROMETHEE and TOPSIS weights
by Tolga Genc
Abstract: The purpose of this paper is to determine the changes of the outrankings of alternatives due to the changes of weights. It is analysed that the altering of weights of PROMETHEE is how affecting the outrankings by using stability intervals. It is also tested that when the changes of weights in PROMETHEE are applied to TOPSIS weights at the same level, how the TOPSIS outranking alters. Weights are subjective factors in multi criteria decision making methods for that reason they vary in determination. When you change the weights, the outrankings of the methods alter. It will be interesting to discuss in this paper how the influence they have on the outrankings of the methods. Sensitivity analysis is performed over PROMETHEE and TOPSIS weights by using stability intervals. In this study the main focus will be stability intervals of weights and the altering of outrankings due to changing of weights. Stability intervals allow seeing at a glance in which ranges the weights of the different criteria could move without affecting the best solution.
Keywords: multi criteria decision making; MCDM; sensitivity analysis; PROMETHEE; TOPSIS.
- A mathematical location-routing model of repair centres and ammunition depots in order to support soldiers in civil wars
by Kaveh Khalili-Damghani, Hossein Naderi
Abstract: One of the most crucial factors in civil wars is to properly support fighting soldiers. Since the opposition forces are usually faced with many difficulties to provide themselves with ammunition, they should use their ammunitions and equipment with extreme care. This makes them establish centres for repairing defective military equipment. This article intends to present a mathematical integer linear programming (ILP) model in order to minimise the expenses related to locations, routing, and reverse logistics of fighting forces. The presented model has been solved by numerical examples of different sizes using Branch and Bound method and its applicability has been shown in the real world problems.
Keywords: location routing problem; LRP; resource allocation; integer linear programming; ILP; Branch and Bound method; mathematical modelling; reverse logistics.
- A Note on the Legal Considerations in Decision Science Models of Collaboration, Information Sharing and Integration in Supply Chains
by Karen Reardon
Abstract: In this research note, we suggest that models, which ignore pertinent laws (including but not limited to competition laws) cannot approximate the risks and rewards of collaborative behavior. This article discusses potential legal violations and seeks to encourage multi-disciplinary approaches to the future development of decision science models of Collaboration, Information Sharing and Integration. It identifies future questions for research and proposes that a multidisciplinary team may be best equipped to explore them.
Keywords: information sharing; collaboration; coordination; cooperation; integration; cooperative decision making; anti-competition law, competition law, antitrust law; vertical integration; market manipulation; securities law.
- A Cross-Cultural Comparison of Whistleblowing Perceptions
by Xintong Cheng, Khondkar Karim, Karen Lin
Abstract: Through an empirical examination, this research reports on the results of cultural influences on whistleblowing decisions and the perception of people from individualistic cultures and those from collectivist cultures. We utilize cultural differences and characteristics between different nations to formulate hypotheses that individuals from collectivist cultures are less likely to be whistle-blowers, and less accepting of whistleblowing behavior, than individuals from individualistic cultures. Data were collected through a survey given to subjects of British and Chinese students from the University of Glasgow. The results support hypotheses about diversity in decisions made by individuals from individualistic cultures compared to those from collectivist cultures. The research findings have implications for the administration of domestic and multinational corporations. In order to enhance the effectiveness of internal control systems in various nations, such systems should take cultural differences into consideration. The results suggest that, compared to collectivist cultures, whistleblowing as an organizational strategy of internal control systems is more likely to be effective in individualistic cultures.

- A grey-based decision-making approach for selecting a reverse logistics provider in a closed loop supply chain
by Roohollah Khodaverdi, Seyed Hamid Hashemi
Abstract: Return of used products is gaining great worldwide attention due to resource depletion, environmental degradation, government legislation, and increasing awareness among people to protect the environment. Nowadays, reverse logistics (RL) is considered very important for organizations to improve their overall environmental and financial performance. Therefore, industries are turning to third-party reverse logistics providers (3PRLPs) for reusing, recycling, and remanufacturing of their products. With the development and advancement of reverse logistics practice, the selection of reverse logistics providers becomes more important. In this paper, a multi-criteria decision making (MCDM) model is developed to guide the selection process of best 3PRLP. To handle the ambiguity, vagueness of the real world data and subjectivity of decision makers assessments, grey theory has been applied. The proposed hybrid methodology is based on Analytical Hierarchy Process (AHP) and grey relational analysis for the selection and evaluation of reverse logistics providers. At first the weights and rating of criteria for all 3PRLPs are described in linguistic variables that can be expressed in grey numbers. Secondly using a grey possibility degree, the ranking of all 3PRLPs is determined. To validate the capability of the proposed model a numerical example is presented in an automotive industry. Finally managerial implications and future research directions conclude the paper.
Keywords: Third-party reverse logistics provider (3PRLP), Closed loop supply chain (CLSC), Grey relational analysis, reverse logistic
- Multi-criteria decision analysis: Methods to define and evaluate socially
by Tim Verheyden, Lieven De Moor
Abstract: Originally being a niche strategy followed by few investors, socially responsible investing (SRI) now represents a significant part of the assets under management. After summarizing empirical evidence on the performance of SRI funds, we present four challenges that are facing the further development of SRI and point to multi-criteria decision analysis (MCDA) as the methodological framework that could help overcome these challenges. A first group of challenges calls for the development of a social performance indicator, which can score and classify mutual funds with respect to social responsibility. Another challenge requires a transparent tool for retail investors interested in SRI to learn about their SRI preferences. Reviewing the three schools of available MCDA methods, we present a concrete approach for future research in building such a social performance indicator and a retail investor tool for SRI.
