Industrial development, accompanying human population growth, has had a major role in creating the situation where bio-diverse materials and services essential for sustaining business are under threat. A major contributory factor to biodiversity decline comes from the cumulative impacts of extended supply chain business operations. However, within Corporate Responsibility (CR) reporting impacts on biodiversity due to supply chain operations have not traditionally been given equal weighting with other environmental issues. This paper investigates the extent of CR reporting in managing and publicising company biodiversity supply chain issues by reviewing a cross-sector sample of publicly available CR reports. The report contents were examined for suggestions of industrial sectorial trends in the level of biodiversity consideration. The reporting of environmental management system use within company supply chain management is assessed in the samples and is considered as a mechanism for responsible supplier partnership working.

Purpose – The objective of this paper is to gain a better understanding of the impact of context on the adoption of e-commerce in supply chains. Design/methodology/approach – A literature review, 45 semi-structured interviews in four different supply chains in the UK healthcare sector, involving 16 different organisations, and additional documentation is used in this study. Findings – The adoption of e-commerce in supply chains is simultaneously affected by two contextual meta-variables: external pressure, which is influenced by supply chain structure, demand and industry characteristics; and internal readiness, which is influenced by IT, organisational and buying need characteristics. Different combinations of these two main variables lead to four different trade-off situations affecting adoption or non-adoption. Research limitations/implications – The empirical research has been undertaken in the specific context of the UK healthcare supply chains. It would be useful to test our findings in other sectors and countries. Practical implications – The paper helps to understand the contextual factors that affect e-commerce adoption and concludes with a framework that differentiates four situations that can improve managers' and researchers' understanding of e-commerce adoption in the future. Originality/value – The contribution of this paper is the recognition that the adoption of e-commerce is affected by factors in both an organisational and a supply chain context, which simultaneously lead to trade-off decisions. Also, unlike most other studies which refer to supply chains and are limited to an organisational perspective or at most a dyadic perspective, this paper builds up a supply chain picture of context by including perspectives from multiple actors in a chain.

Purpose – This paper seeks to investigate the links between different types of visibility, joint initiatives and business performance using the concepts of transparency as a measure of visibility in supply chains. The prognosis that increased supply chain visibility can be achieved through suppliers and customers working on joint initiative(s), the deployment of which leads to collaborative successes, is tested. Design/methodology/approach – Lamming et al.'s transparency concept was used as a basis for the development of a framework for assessing the visibility gaps between the focal company – Rolls-Royce (RR) – and their suppliers. The framework was applied to a particular supplier to identify visibility gaps; subsequently a joint initiative was launched across the supply chain and the benefits measured and assessed. A case study approach was followed due to the contemporary nature of the work undertaken. Findings – The supply chain's performance vis-à-vis schedule adherence was significantly improved as a result of the initiative launched. Additionally, there were improvements in visibility across capacity planning, material ordering and inventory management. Practical implications – The study demonstrated the value of using the developed transparency framework in a structured manner to generate improvements in the supply chain. RR will look to extend its use across other supply chains; the approach could also be extended out to other sectors. Originality/value – The development and application of the transparency frameworks in the aerospace sector are unique and have shown the value of the approach. The work has demonstrated tangibly that the exchange of high-quality information as part of an improvement initiative does lead to significant improvements in the overall performance of the supply chain.

Few people would argue that there is one single solution to the design of a manufacturing supply chain. Relatively recent concepts such as strategic outsourcing and partnership sourcing are extremely valuable to some manufacturing organisations. This paper presents the findings of a comprehensive survey of manufacturing sourcing practices in the UK. This study has set out to understand current and intended practices that manufacturing companies have with their key suppliers, and also the decision processes and circumstances that have caused these relationships to occur.

Decentralised supply chain formation involves determining the set of producers within a network able to supply goods to one or more consumers at the lowest cost. This problem is frequently tackled using auctions and negotiations. In this paper we show how it can be cast as an optimisation of a pairwise cost function. Optimising this class of functions is NP-hard but good approximations to the global minimum can be obtained using Loopy Belief Propagation (LBP). Here we detail a LBP-based approach to the supply chain formation problem, involving decentralised message-passing between potential participants. Our approach is evaluated against a well-known double-auction method and an optimal centralised technique, showing several improvements: it obtains better solutions for most networks that admit a competitive equilibrium Competitive equilibrium as defined in [3] is used as a means of classifying results on certain networks to allow for minor inefficiencies in their auction protocol and agent bidding strategies. while also solving problems where no competitive equilibrium exists, for which the double-auction method frequently produces inefficient solutions.

Research in skill requirements needed by supply chain/logistics (SCL) managers has been published since the early nineties, however, research on what is really taught (e.g. curriculum, learning philosophies) by universities is scant. This paper's aim is to fill in this gap by analysing SCL graduate teaching in the UK. Data from 50 SCL MSc programmes were collected from 43 universities. Findings indicate that there seems to be a gap emerging between industry's needs and the content of the programmes being offered. This gap concerns employability, problem based learning, international business and the acquisition of softer interpersonal and problem solving skills.

This paper proposes a conceptual model for a firm's capability to calibrate supply chain knowledge (CCK). Knowledge calibration is achieved when there is a match between managers' ex ante confidence in the accuracy of held knowledge and the ex post accuracy of that knowledge. Knowledge calibration is closely related to knowledge utility or willingness to use the available ex ante knowledge: a manager uses the ex ante knowledge if he/she is confident in the accuracy of that knowledge, and does not use it or uses it with reservation, when the confidence is low. Thus, knowledge calibration attained through the firm's CCK enables managers to deal with incomplete and uncertain information and enhances quality of decisions. In the supply chain context, although demand- and supply-related knowledge is available, supply chain inefficiencies, such as the bullwhip effect, remain. These issues may be caused not by a lack of knowledge but by a firm's lack of capability to sense potential disagreement between knowledge accuracy and confidence. Therefore, this paper contributes to the understanding of supply chain knowledge utilization by defining CCK and identifying a set of antecedents and consequences of CCK in the supply chain context.

The paper discusses the characteristics of healthcare supply chains, and puts particular emphasis on the implementation of VMI/CMI in this sector specific context. By the means of case study research the paper provides empirical data on the benefits of the above collaborative practices for both the hospital and vendors. The paper contributes to the stream of research on VMI/CMI in the healthcare sector, where limited research attempts have been conducted so far. In contrast to other surveys this case study shows that specific and measurable cost reductions exist, in addition to other improvements such as better control over the inventories, and also in reduction of administrative work. Results obtained may be also relevant to other hospitals and vendors and as they can form a basis for comparisons. Copyright © 2013 Inderscience Enterprises Ltd.
