Abstract
Purpose
The purpose of this paper is to develop a new composite model using structural equation modelling (SEM) and analytic hierarchy process (AHP) for the selection of suppliers.
Design/methodology/approach
In this paper the authors have made an attempt to arrive at the supplier selection score using SEM and AHP. An attempt has been made to develop a new composite model using SEM and AHP technique, based on the survey of 151 respondents. Attributes' weightage are found out using cluster analysis.
Findings
Based on the output from the composite model, cluster analysis has been carried out to find out the strengths and weakness of each supplier on the influencing factors. Based on these findings, the supplier can improve on factors where they lag and can maintain the factors where they excel.
Originality/value
In this paper the authors have made an attempt to arrive at the supplier selection score using SEM and AHP.

Abstract
Purpose
The purpose of this paper is to examine whether preference toward in‐group members can serve as opportunism governance in channel relationships in a collectivist culture. This study proposes a model of opportunism incorporating in‐group preference and trust as antecedents of opportunism. Based on Transaction Cost Economics and Social Exchange Theory, transaction‐specific investment and relationship length are employed in the model as confounding variables of in‐group preference for opportunism and trust.
Design/methodology/approach
Data were collected from 109 Korean department store buyers and analyzed using Structural Equation Modeling (EQS 6.0).
Findings
The results showed that buyers' in‐group preference increased buyers' trust toward suppliers and decreased suppliers' opportunistic behavior. Buyers' increased trust toward suppliers was found to reduce suppliers' opportunistic behavior. Further, Trust was significantly influenced by supplier TSI, but not by length of relationship. On the other hand, opportunism was significantly influenced by length of relationship, but not by supplier TSI.
Research limitations/implications
This study examined only the positive side of in‐group membership. Some criticisms of in‐group preference are favoritism, interference with fair competition, and collective blindness, any of which might decrease the efficiency of business operations. These impacts should be examined to gain a balanced view of the implications of in‐group preference in business settings.
Practical implications
Multinational companies should understand that in‐group membership is an important source of building trust and oppressing opportunism in the Korean market. Multinational companies can strategically approach in‐group members of business partners to become members of those in‐groups.
Originality/value
This is the first empirical study to examine collectivists' tendencies toward in‐group preference as opportunism governance.

Abstract
Purpose
The purpose of this paper is to propose an approach that integrates three complementary perspectives, multi-agent systems, fuzzy logic and case-based reasoning. Unsatisfied customers, information overload and high uncertainty are the main challenges that are faced by today’s supply chains. In addition, a few existing agent-based approaches are tied to real-world supply chain functions like supplier selection. These approaches are static and do not adequately take the qualitative and quantitative factors into consideration. Therefore, an agent-based framework is needed to address these issues.
Design/methodology/approach
The proposed approach integrates three complementary perspectives, multi-agent systems, fuzzy logic and case-based reasoning, as a common framework. These perspectives were rarely used together as a common framework in previous studies. Furthermore, an exploratory case study in an office furniture company is undertaken to illustrate the value of the framework.
Findings
The proposed agent-based framework evaluates supply offers based on customers’ preferences, recommends alternative products in the case of stock-out and provides a collaborative environment among agents who represent different supply chain entities. The proposed fuzzy case-based reasoning (F-CBR) approach reduces the information overload by organizing them into the relevant cases that causes less overall search between cases. In addition, its fuzzy aspect addresses the high uncertainty of supply chains, especially when there are different customers’ orders with different preferences.
Research limitations/implications
The present study does not include the functions of inventory management and negotiation between agents. Furthermore, only the case description and case retrieval phases of the case-based reasoning approach are investigated, and the remaining phases like case retaining, case reusing and case revising are not included in the scope of this paper.
Originality/value
This framework balances the interests of different supply chain structural elements where each of them is represented by a specific agent for better collaboration, decision-making and problem-solving in a multi-agent environment. In addition, the supplier selection and order gathering mechanisms are developed based on customers’ orders.

Abstract
Purpose
The purpose of this paper is to explore the differences in preferred supplier choice criteria between food purchasing agents who focus on supplier security and those that do not. Specifically, this research determines the relationship between purchasing agents’ supplier security preferences and their preferences for product quality, delivery reliability, price, and supplier location. The influence of international sourcing on demand for increased supplier security is also explored.
Design/methodology/approach
Choice-based conjoint analysis with hierarchical Bayes (HB) estimation and t-tests are used to assess and compare the utility food purchasing managers derive from different supplier attributes.
Findings
Purchasing managers that place a higher priority on security when choosing suppliers were willing to pay suppliers a higher price and receive lower levels of delivery reliability in return for higher security but placed less emphasis on suppliers’ product quality. Firms that source internationally do not have a significantly greater preference for advanced supplier security. However, purchasing managers that value supplier security were more likely to source internationally, potentially indicating that security allows for global sourcing by mitigating the increased vulnerability inherent to sourcing abroad.
Research limitations/implications
This research was limited by its focus on the food industry and a relatively small sample size.
Practical implications
This work illustrated that food purchasing managers can be segmented by the emphasis they place on security. Food industry managers will find results useful in formulating their future service offerings with respect to security and other supplier choice criteria.
Originality/value
This is one of few works investigating security as a supplier choice criterion and utilizing HB estimation of choice-based conjoint data.

Abstract
Customer service is often described as consisting of a set of measurable elements. Similarly, market response to customer service may be viewed as consisting of a set of components which are measurable. Most published empirical studies of the relationship between customer service and market response, however, have represented market response through the use of a single measure. The results of an empirical study of interset association between two sets of measures, one representing the elements of customer service (measured in service levels) and the other representing various forms of market response, are reported. Canonical correlation analysis of data collected from 91 grocery channel dyads indicated (as expected) a closer association of market response with customer perceptions of customer service than with supplier perceptions of the same. Also presented, is the contribution of individual measures to the close association between market response and customer perceptions of customer service.

Abstract
Purpose
Due to the increasing awareness of environmental and social issues, many practitioners and researchers have paid attention to sustainable supply chain management. As the performance of suppliers determines the success of supply chains, sustainable supplier selection becomes more and more important. Existing sustainable supplier selection models evaluated the sustainability of suppliers in three aspects (economic, environmental and social) and assumed that values on different criteria can completely compensate for each other directly. However, in reality, criteria in economic, environmental and social aspects are heterogeneous, and the decision-maker’s preferences on criteria belonging to different aspects are different. In this case, values on criteria belonging to different aspects are not allowed to completely compensate for each other directly. To solve this problem, this paper aims to propose a hybrid sustainable supplier selection approach integrating compensatory and non-compensatory decision rules.
Design/methodology/approach
In the proposed approach, the compensatory decision method Technique for Order of Preference by Similarity to Ideal Solution is used to evaluate performances of suppliers with respect to economic, environmental and social aspects. The non-compensatory decision method Elimination and Choice Translating Reality is used to evaluate performances of suppliers on sustainable criteria comprehensively. Through the proposed approach, only criteria belonging to the same aspects are allowed to compensate for each other directly. Finally, experimental results show that the proposed integrated approach is effective and efficient to help the decision-maker select optimal sustainable suppliers.
Findings
This is an original approach that integrates compensatory and non-compensatory decision rules, which can benefit from the two kinds of decision rules simultaneously. The integrated approach can be used as an aid for companies to select the best sustainable suppliers.
Originality/value
This paper presents an original integrated sustainable supplier selection approach using both compensatory and non-compensatory methods. It can benefit from the advantages of both compensatory and non-compensatory methods. The proposed approach can express preferences of the decision-maker on sustainable criteria sufficiently and maximize economic benefits while meeting environmental needs.

Abstract
Purpose
Although the differential roles of political and business ties are recognized in the literature, the interplay between political and business ties remains unclear. This study aims to explore how political ties affect the formation of business ties with unfamiliar partners by analyzing how a buyer’s political ties affect the market-based selection of suppliers, an important channel through which the buyer forms business ties with unfamiliar suppliers.
Design/methodology/approach
A survey of 204 Chinese manufacturing firms was conducted to elucidate the relationship between political ties and the market-based selection of suppliers.
Findings
The findings suggest that buyers with strong political ties are more likely to engage in the market-based selection of suppliers; this positive relationship is diminished when social control is preferred over contractual control in the buyer’s supplier governance and is enhanced when technological uncertainty is high.
Originality/value
First, this study sheds light on the interplay between political and business ties by revealing how the buyer’s political ties affect the formation of business ties with unfamiliar suppliers, as represented by the market-based selection of suppliers. Second, it uncovers the boundary conditions of the effect of political ties by revealing the moderating effect of social control preference and technological uncertainty. Third, it extends the interorganizational governance structure literature from its focus on the complement-substitute debate on social control and contractual control to examine the contingent effect of a hybrid governance structure.

Abstract
Purpose
There is great uncertainty and volatility in the evaluation and measurement of green supplier satisfaction. The purpose of this paper is to fill this gap based on the information entropy theory (IET) to describe the probability of green supplier satisfaction degree.
Design/methodology/approach
The authors introduce a formal model using analytic hierarchy process (AHP), IET and entropy technique for order preference by similarity to an ideal solution (TOPSIS) method to evaluate green supplier satisfaction and promote them for the better implementation of green supply chain management practices.
Findings
The first finding is developing an effective framework for green supplier satisfaction, incorporating various measures of environmental dimension. Second, a hybrid uncertainty decision method is introduced, by integrating AHP and IET and entropy-TOPSIS.
Research limitations/implications
One of the main limitations of the research is that the authors introduced a conceptual example. Real-world applications need to investigate the accuracy and effectiveness of these measures, and the operational feasibility of this method.
Originality/value
This is one of the first works to provide a comprehensive appraisal model for evaluation of green supplier satisfaction. This study and research method can form general guidelines, and organizations can increasingly benefit from using green supplier satisfaction evaluation as a management tool. Green supplier satisfaction evaluation is just the beginning.

The purpose of this paper is to assist a manufacturer with a process to measure the level of preferred supplier status (PSS) of its key suppliers along the timeline.
Abstract
Purpose
The purpose of this paper is to assist a manufacturer with a process to measure the level of preferred supplier status (PSS) of its key suppliers along the timeline.
Design/methodology/approach
In measuring the PSS, the prominent preferred supplier enablers (PSEs) were identified and were broadly categorized under manufacturer’s interest component, common interest component and supplier’s characteristic component. These PSEs were further analyzed by using fuzzy analytic hierarchy process, Euclidean distance measurement and grey relation analysis methods. In order to demonstrate the application and utility of the proposed approach, a case study conducted in an Indian automotive component manufacturing company has been presented.
Findings
By applying the proposed methodology in a case company, the PSSs of five of its key suppliers were measured and then the suppliers’ characteristic scores were determined. Based on these scores, a preferential status plot of the suppliers was developed. Through the status plot, the manufacturer was suggested with whom the proposed initiatives can be productive and with whom the manufacturer has to appeal for improvement strategies.
Research limitations/implications
Since the methodology was tried in the Indian manufacturing environment, the emphasis laid on the PSEs and in turn the measurement of PSS may not address the concern at large.
Practical implications
Measuring PSS would not only earn competitive advantages for the manufacturers but also facilitate the evolution of competitive suppliers.
Originality/value
Measuring PSS along the time would assist a manufacturer to effectively manage the preferences given to its suppliers and thereby enhance the supply base contribution in the value addition process.

Abstract
Purpose
The purpose of this paper is to develop a method to compare supply chains (SCs) of an industry in the scope of supplier's supplier to customer's customer.
Design/methodology/approach
The proposed method is based on five processes provided in SCOR model version 9.0 (plan, source, make, deliver and return) and main business stages of the industry. It uses Data Envelopment Analysis (DEA) and PROMETHEE II, a multiple criteria decision‐making technique, as tools to compare SCs in the process level, business stage level and SC level. Therefore, the method is basically a new combination of existing models and methods including SCOR model, DEA and PROMETHEE II. To show the applicability and strength of the method in comparing SCs, it has been implemented in the seven SCs of the Iran broiler industry as a case study.
Findings
Comparing SCs of an industry via the proposed method results in process benchmarking, business stage benchmarking and SCs ranking in the scope of supplier's supplier to customer's customer.
Originality/value
The suggested method provides realistic and attainable information for SCs' owner/managers to find out the strengths and weaknesses of their SCs and improve their performance by process benchmarking and business stage benchmarking. Also they could identify their competitive position in the industry by SCs ranking.
