Closed-loop supply chains: What reverse logistics factors influence performance?

2016

This paper analyses the inventory and order flow dynamics in closed-loop supply chains (CLSCs). In this kind of supply chains the reverse flow of materials entering the system for recycling purposes complicates the way in which inventories should be managed and replenishment policies should be designed. Specifically, we analyse the relationships between some reverse logistics’ factors (remanufacturing lead-time, return rate of recycled products, reverse order policy, and number of supply chain tiers) on the order and inventory variance amplification. We firstly perform a systematic literature review of the related studies. Secondly, by adopting a difference equation math approach and design…

Impact of reverse logistics on supply chain performance

2013

Purpose – The purpose of this paper is to analyse the impact of reverse logistics on order and inventory variance amplification in a single-echelon supply chain (SC) and to propose a new order policy for dampening such amplification. Design/methodology/approach – A general review of the literature on sustainable operations and on the impact of reverse logistics on SC performance provides the foundation for the study. The authors use difference equation math approach for modelling and analysing a closed SC. A proper design of experiment and data collected from the European Union statistics validate the obtained numerical results. Findings – The variability of reverse flow in a closed loop S…

Do horizontal relationships matter to production and operations managers?

2014

This paper shifts the focus of production, operations and supply chain management business relationships from the vertical to the horizontal side and calls for more research on this issue. The main intent is to provide managerially oriented arguments regarding the linkages between the achievement of operations-related goals and decisions related to horizontal business relationships. Specifically, we address the following research question: Does a linkage exist between production and operations objectives and the decisions a company makes about horizontal agreements, particularly horizontal governance mode choice? To answer this research question, we develop literature-based hypotheses and c…

R&D supply chain and innovation performance: the contingent role of the firm’s position in the network

2013

This paper conceptualizes the supply chain of innovation as a sub-set of the whole innovation network. We focus on the relationship between the activities of purchasing/selling R&D and the firm’s innovation performance. Specifically, we examine how the position of the firm within its innovation network moderates this relationship. Our empirical setting consists in cross-sectional data about 1772 agreements signed by biotech companies between 2006-2010. We find, first, anecdotal evidence of both the existence of the innovation supply chain and the phenomenon of firms’ positioning along it. Second, we find that information richness positively moderates the effect of purchasing R&D services on…

Product Recalls and Supply Chain Responsiveness

2015

The increase in product recalls which occurred in recent years is mainly due to the globalization of the supply chains, in particular the outsourcing and offshoring of manufacturing and distribution. Besides being the main cause of recall, in this paper we argue that outsourcing (domestic and international) and offshoring may also affect the supply chain responsiveness in managing the recall itself. We test a number of hypotheses on this theme empirically on the pharmaceutical sector by using data collected from the American Food and Drug Administration (FDA).

Information Exchange Supply Chain under inventory inaccuracy: a simulation study

2012

The objective of this paper is to contribute at quantifying the impact of inventory record inaccuracy on operational performance and customer service level in collaborative supply chains. To this purpose we analyse the impact of shrinkage errors in the inventory item recording activity in an “information exchange supply chain”, i.e. a supply chain in which companies share information about market demand and use such information for placing orders to their suppliers. We present the mathematical formulation of such a supply chain model and we conduct a numerical simulation and a sensitivity analysis over different level of errors.

How the strategic objectives pursued in inter-firm relationships influence the choice of the governance form: an empirical study in two high-tech Ita…

2012

In today’s competitive landscape, the choice of the appropriate mode to governance an inter-firm relationship is an important factor for companies. In literature several theoretical strands have examined the impact of the alliance purpose on the governance forms. Building on a robust literature review on the topic, this study focuses on a specific issue influencing the choice of the governance form in inter-firm relationships, i.e. the alliances’ purpose with relation to partner’s resources. We gather in a unique framework three typologies of partner’s resources, i.e. production, R&D and marketing, and through two empirical analyses in two different Italian industries, machine tool and phar…

Order allocation in a multiple suppliers-manufacturers environment within a dynamic cluster

2015

This study faces the problem of how to evaluate order allocation strategies in a multiple suppliers-manufacturers environment within a dynamic industry cluster that is an environment in which suppliers adopt a policy based on their performance to select the clusters in which to operate. Therefore, the allocation strategy performed by the manufacturers is crucial to keep a long-term supply chain partnership with a specific industry cluster. We use simulation to evaluate order allocation strategies under different market conditions. We show how an allocation strategy that takes into account the whole supply chain’s perspective leads to a sustainable development of the clusters of suppliers.
