Planning product disassembly for material recovery opportunities

Abstract: SUMMARY This paper addresses an increasingly important aspect of product design and its relationship to life-cycle costing: disassembly for material recovery opportunities (MRO). MRO is defined as an opportunity to reclaim post-consumer products for recycling, remanufacturing and re-use. The authors have developed a methodology which can be used to identify and assess cost-effective characteristics of disassembly for the recovery of products. The central focus of this paper is aimed at improving the efficiency of the disassembly planning process and generating an optimal disassembly sequence. Four criteria are established to optimize the generation of the disassembly sequence: (1) material compatibility, (2) clustering for disposal, (3) concurrent disassembly operations, and (4( maximizing yield. In this paper we define the ‘disassemblability’ of a product as the ability to optimize the design and disassembly process for removal of specific pans or materials in a manner which will minimize costs.

Production planning for companies with remanufacturing capability

Abstract: While much work is in progress on developing environmentally benign products and processes, there has been little work to date on how recycling and remanufacturing may affect companies' operations management policies. In this paper we present linear programming models of production systems with remanufacturing capability. The models can be used to examine the effects of different cost structures on the long-term viability of remanufacturing operations,as well as short-term operations management issues. Work is in progress on applying these models to a telephone remanufacturing operation.

Considering remanufacture and other end-of-life options in selection of fastening and joining methods

Abstract: This paper emphasizes remanufacturing as an end-of-life option and the effects of fastening and joining methods on remanufacture. Three case studies describe examples of fastening and joining that facilitate assembly and recycling but impede remanufacturing. To illustrate the impact of fastening choices on remanufacture relative to other life-cycle concerns, the development of a computer tool that estimates the effects of fastening and joining choices on manufacture, assembly, maintenance, remanufacture and recycling is in progress. The current implementation of the tool is described and used to compare the fastening methods that are used in the case studies with alternative fastening methods. These comparisons suggest that elements of fastening methods that are prone to failure be made separable from the remainder of the part.

A Simulation Model of Drum-Buffer-Rope for Production Planning and Control at a Naval Aviation Depot

Abstract: This paper describes a SLAM II- FORTRAN simulation model of Drum- buffer-rope (DBR) as a production planning and control methodology at the engine component division of a Naval Aviation Depot. The model represents all of the functional areas of remanufacturing facility (a total of 27 shops) required for the repair/overhaul of an aviation component, as well as DBR for production planning and control. The model allows for experimentation in a variety of areas, including setting buffer sizes, buffer management techniques, input/output control, and capacity management. The model experiments indicate that DBR is an extremely robust method of production planning and control and that DBR leads to better performance to schedule, lower work-in- process inventory and improved use of present resources.

Reliability assessment of used parts: an enabler for asset recovery

Abstract: At Xerox, a major management commitment is a 0% material disposition to the landfill. This is accomplished through a process called Asset Recovery Management(ARM) which incorporates into our production design the concept of total recycling. This paper discusses the methodology used to assess the reliability and acceptability of used parts for use in remanufacturing of machines. The most important phases are the failure analysis of field failures and the design and implementation of a production test system to sort for acceptable parts. A case study on a used motor is described to amplify on the methodology suggested here.

Process for remanufacturing charging member, charging member remanufactured by the remanufacturing process, and process cartridge having the charging member

Abstract: A process for remanufacturing a charging member having at least two layers on a conductive support is described. The process involves carrying out mechanical abrasion to remove at least a surface layer of the charging member, followed by forming a layer thereon. Also, a charging member remanufactured by the process and a process cartridge having the hanging member are described.
