The influence of reverse flow on the dynamics of closed-loop supply chains
2014
The purpose of this paper is to study the impact of reverse logistics’ factors on the order and inventory variance amplification in a closed-loop supply chain. We adopt a difference equation math approach for analysing a closed-loop supply chain. Results show how the return flow positively affects both the inventory variance and the bullwhip effect independently of the number of echelons. On the contrary, an increasing remanufacturing lead-time negatively affects both the two metrics studied independently of the above mentioned settings. However, when the number of echelons increases, the benefit provided by the return flow tends to decrease.
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…
A Behavioral Approach for Logistics System Analysis and Design: A Reverse Logistics Case
2002
Traditional logistic system analysis quite often assumes a single decisionmaker (the planner) operating in a state of complete information and full decision power. He pursues the objective of designing an efficient logistic network by solving a sequence of operational problems mainly in the form of optimization models. More realistically, one should consider that the decision power is actually distributed within the logistics system among different actors (agents or holons) having different (conflictual or cooperative) goals, following different behavioural rules and generating interdipendencies. The shift from a SAS (single-agent system) approach to a MAS (multi-agent system) one induces s…
Examining the critical factors that influence the success of construction and demolition waste reverse logistics operations
2022
The reverse logistics (RL) performance of construction and demolition waste (C&DW) differs significantly between countries. Although some countries are successfully circular, other countries are still far behind; with C&DW being largely directed to landfills or being illegally dumped. There is a lack of guidelines on the requirements for transitioning countries towards C&DW diversion, and little attention has been given to the factors that influence the success of C&DW RL and increased circularity. This study aims to develop a framework that helps in structuring and assessing the success of C&DW RL on a regional level and serves as a guide for transitioning developing co…
The future of bottle recycling in the United States of America
2012
In this Master’s thesis, the future of bottle recycling in the United States of America will be examined through interest, incentive and an infrastructure (iii) model. One of the American ways to recycle bottles, namely, the Dream Machine initiative, will be compared to the Finnish bottle recycling system. It will shed light through surveys done from Finnish high school students and randomly selected Americans about bottle recycling behaviour. In addition, two supportive surveys were administered to bring validity about the possible behavioral change through properly implemented recycling systems. The main conclusion is that through a proper implementation of a bottle recycling system, Amer…
