Industrial challenges within the remanufacturing system
This paper is a literature review of challenges within the remanufacturing system. The challenges in the remanufacturing system has been categorised in a collection phase, a remanufacturing process phase and a redistribution phase which the challenges have been presented according to. The causes and effects of each challenge have been explored and are presented in this paper. The final result is a compilation figure with the challenges for the whole remanufacturing system. In general uncertainties and complexity can be seen as the main characteristics for the challenges within the remanufacturing system.
A Methodology for Modeling a Quality Embedded Remanufacturing System
IFIP — The International Federation for Information Processing
The uncertain quality of used products highly affects the performances of remanufacturing systems and quality of remanufactured products. Hence the quality issues of used product cannot be neglected in remanufacturing. To apply the quality concept into remanufacturing system control or simulation, individual management of each product is required. To this end, a multi-agent approach can provide good solutions. The first step in applying the quality concept with the multi-agent approach is an effective modeling of a remanufacturing system. This study proposes a methodology for modeling a quality embedded remanufacturing system (QRS) with two layers. The first layer represents elements in a remanufacturing system as it is. The representation also contains the information of a multi-agent structure for a QRS. The second layer expresses the status of each product and resource agent, and their relationships to manage the multi-agent system. As modeling tools to support the proposed methodology, directed graphs and Petri-Nets are used. A case study is introduced to show an application of the proposed methodology.
Remanufacturing process and its challenges
In the recent years, remanufacture of used-products is becoming an important production activity amongst many companies. This is primarily motivated by the strict environmental regulations, increasing customers' awareness of green environment and economical benefits. Remanufacturing is an industrial process that involves four key processes, namely inspection/grading, disassembly, component reprocessing and reassembly/testing. It is established that the presence and interactions of several unique characteristics within the remanufacturing systems implicates subsequent key processes. These unique characteristics would become challenges to production planning and control activity in any remanufacturing systems. Consequently, it is very imperative that these characteristics are properly taken into account in any production planning and control activity.

Research into effective remanufacturing is recently new and is often concentrated on ensuring that the design of new products to market considers the reuse and reclaim after use. However, the pressure on landfill is already high and remanufacturing solutions are required for products currently at the end of their useful life. The vast majority of these items were produced without consideration of an end-of-life strategy. Remanufacturers are often not the original equipment manufacturer (OEM) but may be third-party contract remanufacturers or independent remanufacturers. OEMs are often very protective of their intellectual property and will not share information even with their contracted partners [1]. Consequently, successful remanufacture is often complicated by the need to “reverse engineer” (often by the disassembly and measurement of new purchased core) a product owing to a lack of available technical information. This can have a significant impact on the speed to market of a re...
Production Planning & Control, 2013
This article presents decision-making tools for remanufacturing. The first decision-making tool was used to address inventory lot-sizing problems in a hybrid remanufacturing-manufacturing system with varying remanufacturing fraction. In this article, the new inventory lot-sizing model with variable remanufacturing lot sizes has been shown to exhibit better performance than the benchmark model with fixed remanufacturing lot sizes. The new inventory lot-sizing model is anticipated to become a valuable decision-making tool in companies that are planning to adopt remanufacturing. The second decision-making tool was applied to address a production and inventory planning problem in a remanufacturing system considering different remanufacturing policies for a given remanufacturing strategy. For a remanufacture-to-stock system with two quality remanufacturables groups four alternative policies were examined, a policy which specifies simultaneous processing utilising dedicated resources was shown to be the best policy to achieve a shorter remanufacturing cycle time. For a remanufacture-to-order system with two quality remanufacturables groups, the three relevant policies of the four alternative policies were examined, a policy which specifies sequential processing and switching between various quality remanufacturables groups was shown to be the best policy to achieve a shorter remanufacturing cycle time. The production and inventory planning simulation models in a remanufacturing system are expected to become significant decision-making tools in remanufacturing operations.
Remanufacturing in automotive industry: Challenges and limitations
Journal of Industrial Engineering and Management, 2011
Purpose: The aim of this paper is to provide the framework for management of reverse flow of materials in automotive industry. The emphasis is placed on the remanufacturing activities. Materials management in such conditions is a real challenge. The cause for this is parallel use of raw materials and reused materials. Such hybrid flows of materials are characterized by increased level of uncertainty connected with amount, quality and timing. Design/methodology/approach: This paper presents a comprehensive review of remanufacturing and traditional manufacturing. The stabilization of reverse flows is crucial for continuity of remanufacturing operations. The simulation model and results are discussed regarding stabilization of the reverse flows. Findings: Authors identify main problems that appear in the area of combining at the production system forward and reverse flows of materials. The agent-based technology is applied for configuration and stabilization of reverse network. Research limitations/implications: Paper is case -oriented. Practical implications: Both logistician and IT researchers might benefit from authors approach. Journal of Industrial Engineering and Management -http://dx.doi.org/10.3926/jiem.2011.v4n3.p453-466 -454 -Originality/value: Authors provide an interdisciplinary approach combining operations management, logistics and information technology.
A Decision Support Methodology for the Design of Reconfigurable Assembly Systems
The design phase of assembly systems under uncertain product-mix and product volume settings is challenging for both manufacturers and researchers. One of the design paradigms to deal with uncertain and dynamic environments is through reconfigurable system designs. This paper presents the formulation and a solution approach for supporting the design of assembly systems that are based on reconfigurable and modular resources. The method assists manufacturers in the search of optimal design solutions and future reconfiguration actions. Systems designed this way can efficiently respond to external changes, such as evolving product types and uncertain demand scenarios. The proposed methodology has been used to solve a real use-case in the ReCaM project, and preliminary results demonstrate its potential benefits for industrial settings. © 2018

Although production planning in remanufacturing systems has attracted great interest from the research community, only a couple of real industrial applications can be perceived. Additionally, in real cases, companies are faced with manufacturing multiple products, which further complicates remanufacturing production planning (RPP). Therefore, there is a need to optimise RPP where manufacturers are involved in remanufacturing multiple products. Also optimized systems should consist of a number of uncertainties, such as the uncertain quality of the returned products. Because of these uncertainties the manufacturers have to use new parts or components-with both higher environmental impacts, as well as costs. In the present paper a line balancing scheduler of a remanufacturing system is presented-focusing on the disassembly, machining and reassembly of parts. The objective of the paper is the reduction of usage of the energy and cost intensive new parts with production scheduling using a genetic algorithm (GA). The achievements are illustrated and presented with a real industrial use case from a gas engine producer. A discrete event simulation (DES) is used for evaluation purposes and the results from the scheduler are compared with benchmarks of the current production planning of the gas engine manufacturer.
Timing Matching Method of Decision-Making in Predecisional Remanufacturing for Mechanical Products
Procedia CIRP, 2019
In today's business environment, the trend towards more product variety and customization is unbroken. Due to this development, the need of agile and reconfigurable production systems emerged to cope with various products and product families. To design and optimize production systems as well as to choose the optimal product matches, product analysis methods are needed. Indeed, most of the known methods aim to analyze a product or one product family on the physical level. Different product families, however, may differ largely in terms of the number and nature of components. This fact impedes an efficient comparison and choice of appropriate product family combinations for the production system. A new methodology is proposed to analyze existing products in view of their functional and physical architecture. The aim is to cluster these products in new assembly oriented product families for the optimization of existing assembly lines and the creation of future reconfigurable assembly systems. Based on Datum Flow Chain, the physical structure of the products is analyzed. Functional subassemblies are identified, and a functional analysis is performed. Moreover, a hybrid functional and physical architecture graph (HyFPAG) is the output which depicts the similarity between product families by providing design support to both, production system planners and product designers. An illustrative example of a nail-clipper is used to explain the proposed methodology. An industrial case study on two product families of steering columns of thyssenkrupp Presta France is then carried out to give a first industrial evaluation of the proposed approach.
