THE ROLE OF SUPPLY MANAGEMENT CAPABILITIES IN GREEN SUPPLY

Managers realize that they should avoid complex green supply initiatives when they do not have the capabilities to implement them. However, they have little guidance on how these capabilities can be developed. This paper provides an initial analysis of the role of supply management capabilities in green supply. We argue that the implementation of green supply is better explained by focusing on the development and deployment of an organization's specialized internal resources, rather than by the more usual focus on external environmental pressures on a firm. Further, we argue that capabilities appropriate for green supply are developed by a proactive corporate environmental stance and by a more strategic purchasing and supply management approach. We test our model using data from a two‐phase survey of 70 operating units within UK public limited companies. Our results indicate support for our conjecture that supply management capabilities are jointly developed by a proactive corporate environmental approach and a strategic purchasing and supply process. Our study results should be useful to business strategists, regulators, and researchers interested in the predictors of corporate green behavior. They should also assist future researchers in many branches of environmental management who are seeking to explore the role of the internal capabilities of firms in supporting environmental management.     

Introduction to the special issue: after trust

‘Trust’ has long been seen as critical to the success and durability of trading networks, and conceptualized as a positive moral sentiment that is embedded in shared kinship, ethnicity or friendship, or in shared frameworks of morality. Other recent studies of business communities suggest that the ability to work in settings characterized by pervasive mistrust is a key factor in the development of commercial acumen and a determinant of success. Here, the authors argue that a focus on trust and mistrust, and an underlying concern with ethics and morality, can obscure equally critical factors that inform the durability of trading networks. They offer ethnographic accounts of different inter‐Asian trading networks active in the city of Yiwu, which is one of China's most dynamic and diverse ‘international trade cities’. Yiwu is home to the largest wholesale market of small commodities in the world, and attracts traders and merchants from across the planet; more than 12,000 foreign traders are also resident in the city. The authors of the articles presented here analyse the durability of these networks in relation to broader geopolitical processes and contexts. They argue that success often depends on the ability to negotiate geopolitical shifts and the fault lines of political identity. They trace traders’ efforts to create institutions that allow them to withstand geopolitical transformations. They also document the ability of trading networks to operate flexibly across different social fields, showing that resilience often depends on the ability to navigate and profit from shifting relations between economic, political and familial domains.     

EVALUATING ORDER RELEASE MECHANISMS IN A JOB SHOP WITH SEQUENCE-DEPENDENT SETUP TIMES

Job-release mechanisms in job-shop control are receiving increased recognition in recent research. However, there is considerable disagreement over the benefits of sophisticated job-release mechanisms, and they remain to be tested in various operating environments. In our study, we extend previous job-releasing research by examining several job-release mechanisms in a different operating environment-a sequence-dependent setup job shop. We tested these release mechanisms, originally developed for a machine-constrained job shop, in conjunction with two groups of sequencing rules-ordinary and setup-oriented sequencing rules. We measured shop performance in terms of total cost, the sum of inventory-holding and late-penalty costs. We developed a simulation model of a nine-machine job shop for our experiment.     

On the Contingent Valuation of Safety and the Safety of Contingent Valuation: Part 1-Caveat Investigator

This article reports the results of two studies aimed at testing and refining a procedure for estimating willingness-to-pay based monetary values of safety using the contingent valuation method. In spite of the fact that respondents were given the opportunity to discuss various safety issues and key concepts in focus group meetings held in advance of individual interviews, and were also given ample opportunity to revise their responses in the light of the overall pattern of these responses, the results show clear evidence of extensive and persistent insensitivity to the scale and scope of the safety improvements that were specified in the contingent valuation questions, as well as vulnerability to framing effects. This clearly casts serious doubt on the reliability and validity of willingness-to-pay based monetary values of safety estimated using conventional contingent valuation procedures.     

A decision support tool for planning bills-of-material

In this paper, the framework for a decision support tool for planning bills-of-material is presented. This tool generates a set of modular planning bills-of-material from the manufacturing bills-of-material for a company. The tool attempts to consolidate options in a product family which are specific. The force with which the tool attempts to consolidate two or more options is dependent on the financial control parameters. As well as having a minimum amount of common material, the financial value of such a match must also be of sufficiently high value to be worth planning together. The tool also examines the long-term inventory effect of planning two or more options as common.
