Remanufacturing: a key strategy for sustainable development
Remanufacturing is a process of bringing used products to "like-new" functional state with warranty to match. It recovers a substantial proportion of the resource incorporated in a used product in its first manufacture, at low additional cost, thus reducing the price of the resulting product. The key remanufacturing problem is the ambiguity in its definition leading to paucity of knowledge and research in the process. Also, few remanufacturing tools and techniques have been developed to improve its efficiency and effectiveness. This paper addresses these issues by describing the findings of in-depth UK case studies, including, a robust remanufacturing definition and an analytic model of the generic remanufacturing business process for improving remanufacturing knowledge and expertise
Drivers and Barriers of Mobile Phone Remanufacturing Business in Indonesia: Perspectives of Retailers
Remanufacturing is deemed to be effective in reducing WEEE. Existing studies on remanufacturing mostly focus on operational issues, product acquisition, and pricing. However, some doubts about remanufacturing business arise in developing countries, where there is less regulation on remanufacturing and less environmental awareness. This study aims to investigate the prospects of remanufacturing business from the retailers' perspectives through in-depth interviews on three retailers in Surabaya, Indonesia. The main drivers for mobile phone remanufacturing business are its affordable and competitive price, big demand for popular mobile phones and high-end mobile phone, the opportunity for specification upgrade, and its suitability with the needs of Indonesian people. The main barriers for remanufacturing business are the possibility for cannibalizing new mobile phones' market share, the uncertainty of core supply, discontinuity of replacement part supply, lack of product knowledge among consumers and retailers, hesitation of retailers to sell remanufactured products, and lack of strict and clear regulations about remanufacturing business. Findings of this study provide insights to prospective mobile phone remanufacturers of what needs to be tackled to start a prosperous business. On the theoretical side, it provides complementary knowledge to existing studies that have been conducted mostly on countries that have higher environmental awareness
Addressing decision making for remanufacturing operations and design-for-remanufacture
Remanufacturing is a process of returning a used product to at least original equipment manufacturer original performance specification from the customers' perspective and giving the resultant product a warranty that is at least equal to that of a newly manufactured equivalent. This paper explains the need to combine ecological concerns and economic growth and the significance of remanufacturing in this. Using the experience of an international aero-engine manufacturer it discusses the impact of the need for sustainable manufacturing on organisational business models. It explains some key decision-making issues that hinder remanufacturing and suggests effective solutions. It presents a peer-validated, high-level design guideline to assist decision-making in design in order to support remanufacturing. The design guide was developed in the UK through the analysis of selections of products during case studies and workshops involving remanufacturing and conventional manufacturing practitioners as well as academics. It is one of the initial stages in the development of a robust design for remanufacture guideline
Strategic factors on interpreting remanufacturing quality- Certifying framework to address warranty aftermarket for Malaysian industry
While the concept of remanufacturing is gaining popularity globally, literature and
theory on strategic decision-making on certifying for warranty in this area remain limited. A
strategic and establish concept flow is developed based on extensive literature review and
surveys with experienced experts who are dealing with remanufactured, reconditioned, rebuilt
and reused components. The remanufacturing research on evaluating quality assurance of
remanufactured component targets macro-level parameters and the indicators which must be
confirmed for evaluation. The strategic remanufacturing factors identified from the literature
review are discussed in a brainstorming session with a number of remanufacturing researchers
and academic experts. The study is further broadened by industrial surveys and case studies to
justify the inputs on developing a framework to certify remanufactured components.
Preliminary results have established the key factors of remanufacturing quality control that
might lead to the strict quality assurance of remanufactured components. Later, the developed
framework can be used as a benchmarking tool to certify remanufactured components and
warranty issuance. The findings serve as the foundation for further research concerning
Original Equipment Manufacturer (OEM) or Original Equipment Remanufacturer (OER) and
Independent Equipment Remanufacturer (IER) in the Malaysian Remanufacturing Industry
Simple heuristics for push and pull remanufacturing policies
Inventory policies for joint remanufacturing and manufacturing have recently received much attention. Most efforts, though, were related to (optimal) policy structures and numerical optimization, rather than closed form expressions for calculating near optimal policy parameters. The focus of this paper is on the latter. We analyze an inventory system with unit product returns and demands where remanufacturing is the cheaper alternative for manufacturing. Manufacturing is also needed, however, since there are less returns than demands. The cost structure consists of setup costs, holding costs, and backorder costs. Manufacturing and remanufacturing orders have non-zero lead times. To control the system we use certain extensions of the familiar (s,Q) policy, called push and pull remanufacturing policies. For all policies we present simple, closed form formulae for approximating the optimal policy parameters under a cost minimization objective. In an extensive numerical study we show that the proposed formulae lead to near-optimal policy parameters.inventory control;remanufacturing;heuristics
Periodic Review, Push Inventory Policies for Remanufacturing
Sustainability has become a major issue in most economies, causing many leading companies to focus on product recovery and reverse logistics. This research is focused on product recovery, and in particular on production control and inventory management in the remanufacturing context. We study a remanufacturing facility that receives a stream of returned products according to a Poisson process. Demand is uncertain and also follows a Poisson process. The decision problems for the remanufacturing facility are when to release returned products to the remanufacturing line and how many new products to manufacture. We assume that remanufactured products are as good as new. In this paper, we employ a "push" policy that combines these two decisions. It is well known that the optimal policy parameters are difficult to find analytically; therefore, we develop several heuristics based on traditional inventory models. We also investigate the performance of the system as a function of return rates, backorder costs and manufacturing and remanufacturing lead times; and we develop approximate lower and upper bounds on the optimal solution. We illustrate and explain some counter-intuitive results and we test the performance of the heuristics on a set of sample problems. We find that the average error of the heuristics is quite low.inventory;reverse logistics;remanufacturing;environment;heuristics
Inventory strategies for systems with fast remanufacturing
We describe hybrid manufacturing/remanufacturing systems with a longlead time for manufacturing and a short lead time for remanufacturing.We review the classes of inventory strategies for hybrid systems inthe literature. These are all based on equal lead times. For systemswith slow manufacturing and fast remanufacturing, we propose a newclass. An extensive numerical experiment shows that the optimalstrategy in the new class almost always performs better and often muchbetter than the optimal strategies in all other classes.logistics;remanufacturing;stochastic inventory control
