Tracking of supply chain and reverse logistics of products to reduce environmental impact

ABSTARCT :

Based on environmental, legal, social, and economic factors, reverse logistics and closed-loop supply chain issues have attracted attention among both academia and practitioners. This attention is evident by the vast number of publications in scientific journals which have been published in recent years. Hence, a comprehensive literature review of recent and state-of-the-art papers is vital to draw a framework of the past, and to shed light on future directions. The aim of this paper is to review recently published papers in reverse logistic and closed-loop supply chain in scientific journals. A total of 382 papers published between January 2007 and March 2013 are selected and reviewed. The papers are then analyzed and categorized to construct a useful foundation of past research. Finally, gaps in the literature are identified to clarify and to suggest future research opportunities.

EXISTING SYSTEM :

? The analysis suggests that the practices that lead to a more sustain-able supply chain are equal parts best practices in traditional supply chain management and new behaviors, some of which run counter to existing accepted ‘‘best’’ practice. ? The aim of their research was to identify the kinds of relationships that exist between remanufacturers and customers/suppliers of cores, and how these relationships can be managed. ? An analysis of the current study reveals the existence of several opportunities for future research based on identified gaps in various investigated papers.

DISADVANTAGE :

? Fuzzy logic is often utilized in decision-making problems, which usually consist of some weights in addition to designing and planning problems. ? Various approaches are used by researchers to solve mathematical problems in RL/CLSC. ? As real-world problems are always complex and complicated, problems cannot be modeled using simple linear programming approaches.

PROPOSED SYSTEM :

• They proposed an integrated supply chain model regarding modeling constraints that included the strategic and operational alignments, system interoperability, information sharing and coordination of activities. • They proposed a decision conceptual framework including generic process mapping, decisions, economic aspects, and performance measures with a distinction in regard to strategic, tactical, and operational level. • Their proposed classification allows insight into what conditions are needed to apply for successful product acquisition.

ADVANTAGE :

? One of the important research categories in RL/CLSC is studying performance evaluation of various networks, recovery strategies, etc. ? They proposed a decision conceptual framework including generic process mapping, decisions, economic aspects, and performance measures with a distinction in regard to strategic, tactical, and operational levels. ? They also proposed a Quality Function Deployment (QFD) and Linear Physical Programming (LPP)-based mathematical model to measure the performance of a RL/CLSC.
