closed-loop supply chain network (clscn) design aims at incorporating environmental considerations into the traditional supply chain design by including recycling, disassembly and reuse activities. in a clscn, the environmental considerations can also be facilitated by resorting to environmentally friendly materials and enhancing product reuse through the design of an appropriate product recove...

The increased scrutiny of a product’s effects on the environment has led industry to embrace Environment Conscious Design and Manufacture (ECDM) practices. Disassembly of a product at the end of its useful life is an integral part of the ECDM paradigm. Disassembly facilitates the end-of-product life options such as recycling, remanufacture, reuse and safe disposal. As industries take active ste...

This paper analyzes the problem of disassembling multiple selected components from an assembly, defined as selective disassembly, and presents algorithms for efficient disassembly analysis of geometric models. Applications for selective disassembly include assembling, maintenance and recycling. A new approach called ‘Disassembly Wave Propagation’ is proposed to determine a selective disassembly...

For companies, the improvement of the recyclability performance of their newly designed products is becoming an integral part of product development process. The concept of environmental conscious design (ECD) has been adopted to assist the environmental performance of the products at the early stage of designing. This new trend requires that the design strategies need to be modi"ed by integrat...

A disassembly process plan (DPP) is a sequence of disassembly tasks which begins with a product to be disassembled and terminates in a state where all the parts of interest are disconnected. Disassembly process planning is critical for minimizing the resources invested in disassembly and maximizing the level of automation of the disassembly process and the quality of the parts (or materials) re...

Legislative changes triggered by the exhaustion of natural resources have increased the importance of disassembly as a form of recycling. The implementation of computer-supported procedures in recycling has become indispensable. Time management data was used to develop a tool for the economic planning of disassembly processes, allowing for load balancing of disassembly systems with division of ...

ESCRT-III undergoes dynamic assembly and disassembly to facilitate membrane exvagination processes including multivesicular body (MVB) formation, enveloped virus budding, and membrane abscission during cytokinesis. The AAA-ATPase Vps4 is required for ESCRT-III disassembly, however the coordination of Vps4 ATP hydrolysis with ESCRT-III binding and disassembly is not understood. Vps4 ATP hydrolys...

In this article, a personal computer disassembly cell is presented. With this cell, a certain degree of automatism is afforded for the non-destructive disassembly process and for the recycling of these kinds of mass-produced electronic products. Each component of the product can be separated. The disassembly cell is composed of several sub-systems, each of which is dedicated to the planning and...

Manufacturing industries are beginning to face one of the consequences resulting from the rapid development which has occurred during the last decade. The most evident effect is that landfill capacity is being used up. Therefore, a systematic approach to recycling is both urgent and imperative. It has been also recognized that appropriate disassembly of used products is necessary in order to ma...
