Conceptualizing and managing service supply chains

The supply chain management (SCM) literature is dominated by studies in industrial markets and studies that deal with the supply chains of manufactured goods. This paper develops a framework for conceptualizing and managing the supply chains of services. The few studies that deal with services' supply chains either focus on a particular business service sector or they adopt an unvaried approach to the management of different service supply chains. The paper draws insights from the existing frameworks for SCM and takes into account the peculiar characteristics for the production and delivery of services across several service industries. Based on the analysis of several processes, areas of concern for supply chain managers are identified, and a research agenda for services SCM phenomena is proposed.     

The Chinese paradigm of global supplier relationships: Social control,formal interactions and the mediating role of culture

This paper reports the results of a study that examined how firms can establish successful business relationships with Chinese suppliers. Its aim is to explore salient characteristics of the nature of buyer supplier relationships with the emergence of China as a dominant economic power. Two surveys have been conducted that investigated several factors that inhibit and enable effective supplier relationship management (SRM) between organisations sourcing from China and Chinese suppliers, and explored the impact of cultural characteristics of Chinese management on the nature and performance of supplier relationships. The research highlights the importance of the social control aspect of governance structure of supplier relationships and stresses that both social and formal control mechanisms should be implemented for more effective relationships with Chinese suppliers. It also demonstrates the need for companies to recognise the importance of guanxi and several cultural characteristics of the Chinese style of management in SRM and advocates the need for the development of a hybrid Sino-Japanese and global supplier relationship management paradigm that incorporates elements from the existing SRM models. It generates insights into how the cultural context of emerging markets affects the nature of business relationships and generates a research agenda in the field of supply chain management that can explore the development of new paradigms in supplier relationships management. The main theoretical argument put forward centres on the need for the development of a new global supplier relationship management paradigm that will take into account the cultural elements of the Chinese society.     

Multivariate Mixed Models for Open-Ended Contingent Valuation Data: Willingness To Pay For Conservation of Monk Seals

Although dichotomous choice (DC) contingent valuation (CV) has been recommended by the US NOAA 'blue-ribbon' panel for large-scale contingent valuation studies, useful information can still be obtained from smaller, open-ended (OE) studies, often undertaken as a precursor to a DC survey. The CV study considered here was carried out in Greece and looked at willingness-to-pay (WTP) for protecting the Mediterranean monk seal (Monachus-monachus) in the Aegean area. This is the most endangered seal in the world, and the application of the CV methodology was the first such application in Greece. The OE data consist of two responses: first, a binary response detailing whether or not respondents were in principle prepared to pay for the protection of this seal; secondly, those respondents who answered 'yes' to the first question were then asked to state their maximum WTP for such protection. A multivariate binomial – log-normal mixture model is used to develop a bid function including explanatory variables such as income, sex, age and education. Such a modelling approach provides an alternative to more commonplace tobit estimation. However, the model is extended to include further information which was collected on:(a) an increased WTP amount given in response to information that the initial WTP amount may not be enough to prevent the extinction of the seal;(b) respondents were asked to divide their final WTP amount between use, option and existence values, the latter requiring a multivariate model with four binary and four continuous responses per individual in the same model.The discussion focuses on the methodological issues raised with some comment on the substantive interpretation of results.     

Exploring early purchasing involvement in discontinuous innovation: A dynamic capability perspective

This paper aims to address the gap concerning our knowledge about early purchasing's involvement (EPI) in new product development (NPD) projects in contexts characterized by discontinuous innovation. We adopt a dynamic capability perspective to explore how existing sourcing and supplier relationship management capabilities are adapted when purchasing agents become involved in discontinuous innovations projects. We use an embedded case-study approach to study four NPD projects in a heating, ventilation, and air conditioning (HVAC) company. The case studies are based on interviews with managers and staff from the research and development, purchasing, and marketing departments, as well as suppliers involved in the projects. Our empirical findings capture emerging purchasing practices including a “reversed” sourcing process, purchasing-marketing interaction, and the coordination of “a learning atmosphere” between the R&D department and suppliers through proactive innovation meetings and creativity workshops. We derive propositions to conduct further research into the role of the purchasing department in times of discontinuous innovation. We also provide a framework of sourcing and supplier-relationship practices that firms can use when embarking on discontinuous innovation.     

Berth scheduling by customer service differentiation: A multi-objective approach

In this paper the discrete and dynamic berth allocation problem is formulated as a multi-objective combinatorial optimization problem where vessel service is differentiated upon based on priority agreements. A genetic algorithms based heuristic is developed to solve the resulting problem. A number of numerical experiments showed that the heuristic performed well in solving large, real life instances. The heuristic provided a complete set of solutions that enable terminal operators to evaluate various berth scheduling policies and select the schedule that improves operations and customer satisfaction. The proposed algorithm outperformed a state of the art metaheuristic and provided improved results when compared to the weighted approach.
