Generic production planning model for remanufacturing systems

Abstract

Remanufacturing, one of the most advanced product recovery options, processes used or end-of-life products with disassembly, reprocessing, and reassembly operations in such a way that their qualities are as good as new. This paper focuses on production planning in remanufacturing systems over a given planning horizon with discrete time periods. The main decisions are: (a) the number of used or end-of-life products to be disassembled and disposed; (b) the number of parts or components to be reprocessed, disposed, and newly purchased; and (c) the number of products to be reassembled. The objective is to maximize the total profit, i.e. the difference between the sales revenue and the relevant costs. In particular, set-up costs and times are explicitly considered since set-ups are significant in remanufacturing systems. As an extension of the existing literatures on production planning in remanufacturing systems, a generic mixed integer programming model is suggested that incorporates the detailed processes of the remanufacturing process. Then, owing to the complexity of the problem, two types of heuristics based on the linear programming technique are developed. To show the performances of the heuristics, computational experiments were done on some test instances, and the results are reported.

A quality evaluation model of reuse parts and its management system development for end-of-life wheel loaders

“…By applying those recovery strategies, some parts as whole or merely their material can be reused directly, or after only more or less repair by manufacturing process. These methods are categorized as remanufacturing (Doh and Lee, 2010;Hatcher et al, 2011). In contrast to only material recycling, remanufacturing will reduce environmental impacts by retaining the geometrical form as well as functions of the product, thereby preserving its economic and environmental values Mangun and Thurston, 2002).…”

“…When all economically valuable components are retrieved, first, it is necessary to determine the optimal stage of disassembly (Go et al, 2011), and to select a suitable disassembling evaluation methodology covering the consideration of economic value, environmental impact, associated costs or maximal rate of return as well as the suitable disassembling time (Amelia et al, 2009;Lee et al, 2001) and a feasible disassembling route planning (Krikke et al, 2008). Some researchers agree that part recovery should begin with design phase by selecting suitable materials for preventing waste with minimal environmental impact (Chan and Tong, 2007;Doh and Lee, 2010;Gehin et al, 2008;Nicholson et al, 2009). There also have been a growing number of researches on vehicle remanufacturing including the legislation, policy, profit, business behavior, manufacturing process, evaluation and decision strategy, etc.…”

Solution algorithms for dynamic lot-sizing in remanufacturing systems

“…According to Doh and Lee (2010), the problems considered in previous research can be classified into single-stage and multi-stage ones. Most previous research articles consider single-stage problems in which the three subsystems are aggregated into one system while considering returns of used or endof-life products.…”

“…Also, Franke et al (2006) reported another case study on production planning in remanufacturing mobile phones. Recently, Doh and Lee (2010) suggested an integer programming model for a production planning problem that incorporates the characteristics of material flows in typical remanufacturing systems and suggested heuristics based on the linear programming relaxation technique.…”

A hybrid electromagnetism-like algorithm for integration of process planning and capacitated lot-sizing problem

“…Therefore desirable machines are selected repeatedly, whereas in production planning one task could be dependent on each machine. Owing to the dynamic nature of a production environment, for example in new project scheduling [9], manufacturing systems [10], or real-time process planning under process deterioration [11], the time delay between the planning phase and the execution phase may cause an effective change in the sources being used in the plan: thus that plan is no longer possible in practice, and it ought to be modified in order to take account of the changes on the shop floor.…”
