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

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. Abstract Disassembly is a key operation that differentiates remanufacturing from traditional manufacturing. However, various factors that affects the process of disassembly are not clearly understood by the researchers. This study focuses on identifying and analyzing the factors that affect the disassembly process in remanufacturing organizations. A literature survey is conducted to identify the factors that can influence the disassembly of products. A total of 17 factors are obtained which are further classified into three main factors viz. Organizational Capabilities (OC), Process Choices (PC) and Product Attributes (PA). An approach based on Analytical Hierarchy Process (AHP) is utilized to analyze the factors for developing a list of priority of these factors. A team of 8 experts from industry and academia is involved in this research for collecting their opinions. Results of this study show that product attributes play a key role in the disassembly of products for remanufacturing. 'Value of recovered products', 'number of components', 'sequence of disassembly', 'volume of cores supply' and 'implementation of ecodesign principles' are identified as the top five factors affecting the process of disassembly. The findings of this research can be useful for effective disassembly of products in remanufacturing based organizations. The decision makers of remanufacturing organizations can use the priority list of factors developed in this study for managing the disassembly activities in the organization.
