Abstract:
The time and effort required for maintenance of an automobile system are highly dependent on its disassemblability, which is one of the most important attributes of its maintainability. To evaluate the disassemblability index, i.e. to measure the ease of disassembly, the disassemblability factors (both the design factors and the contextual factors) of an automobile system are identified. These and their interrelations are modelled by considering their structure using the graph theory. The directed graph (digraph) of the disassemblability of the automobile system is defined; the nodes of this represent its disassemblability factors, while the edges represent their degrees of influence. An equivalent matrix of the digraph establishes the system’s disassemblability function which characterizes the disassemblability of the system, leading to development of the disassemblability index. A high value of the disassemblability index indicates that it is very easy to remove or replace parts. The disassemblability index ratio is used to compare the actual conditions of disassembly with the ideal conditions of disassembly. A case study of an automobile gearbox is illustrated using the step-by-step procedure of the proposed methodology of disassemblability. The proposed methodology is helpful to evaluate and compare various alternative designs of the automobile system and, therefore, can aid the design and development of automobile systems from the disassembly viewpoint.

Abstract:
In view of the fuzziness and uncertainty characteristics of the index and evaluation incompatibility in the disassembly evaluation process, the disassembly evaluation model of fuzzy matter-element analysis based on entropy was proposed. Firstly, the fuzzy matter-element matrix and weight matrix was established, based on the analysis of the factors having influences on disassemblability. Then the dependent degree of each scheme was calculated to rank disassemblability of the product design schemes. Additionally, the index weight was determined by the method of entropy, which can effectively avoid interference of subjective factors in the process of weight determination. Finally, an example of disassemblability evaluation was given to show the effectiveness of the method.

Abstract:
This paper presents a method for the automatic generation of robotic assembly sequences based on the verification of a disassemblability for a part to be disassembled. To derive the disassemblability of a candidate part, we first inference collision free assembly directions by extracting separable directions for the part and calculating the separability which gives information as to how the part can be easily separated. Using the result, we determine the disassemblability defined in terms of the separability and stability costs. The separability cost represents a facility of the part disassembly operation, while the stability cost represents a degree of the stability for the base assembly motion which gives a guidance for design of jig/fixture. The proposed method provides a potentially local optimal solution for finding a cost effective assembly plan, and the feasibility of generating robot motion programs by evaluating separable directions in flexible manufacturing applications. A case study is given to illustrate the concepts and procedure of the proposed scheme.

Abstract:
Disassembly Sequence planning is the important module of virtual maintenance. Its foundational task is to test the disassemblability of parts, find out all the feasible disassembly sequences of targeted parts and search for the near-optimal disassembly sequence. In the paper, the spherical algorithm is used to test the disassemblability of parts. And then the disassembly direction of parts is determined by rules which are the simplified version of Gaussian map approach. Thus the near-optimal disassembly sequence is found out by optimizing all feasible disassembly sequences of targeted parts by ant colony algorithm. The simulation result of the sequence optimization proves to be the same with manual calculation considering comprehensive cost of the change of disassembly tools and disassembly directions. The set of approaches can be reference for disassembly sequence planning of large-scale mechanical products.

Abstract:
Majority of the products get discarded at end-of-life (EoL), causing environmental pollution, and resulting in a complete loss of all materials and embodied energy. Adopting a closed-loop material flow approach can aid preventing such losses and enable EoL value recovery from these products. Design and engineering decisions made and how products are used impact the capability to implement EOL strategies such as disassembly and remanufacturing. Some underlying factors affecting the capability to implement these EOL strategies have been discussed in previous studies. However, relevant metrics and attributes are not well defined and comprehensive methods to quantitatively evaluate them are lacking. This study will first identify key lifecycle oriented metrics affecting disassemblability and remanufacturability. Then a methodology is proposed for the quantitative evaluation of these strategies considering the quality of returns, product-design characteristics and process technology requirements. Finally, an industrial case-study is presented to demonstrate the application of the proposed method.

Abstract:
With a continuous annual growth of air traffic by nearly 5%, an additional paradigm change towards industrially producible products is necessary to meet future demands of new airplanes and aero engines. To ensure the producibility of more and more sophisticated aero engines, an assessment of assemblability and disassemblability during preliminary design becomes necessary in this context. Major cost drivers can be identified at an early stage in the product development process regarding assembly-feasible design of the product and the corresponding assembly system. This paper introduces a 3D preliminary design model and a methodology to assess the assemblability and disassemblability of civil aero engines during preliminary design. Based on a systematic evaluation of three different variants of low-pressure turbine modules, implications for a reduction of the assembly and disassembly time can be deduced. Hence, optimization potentials for product design as well as for the design of the corresponding assembly system are identified. The generic models and parametric evaluation methodology of the presented approach allow an application on further aero engine modules, new aero engine technologies as well as other fields.

Abstract:
Products are traditionally designed mainly to meet functional requirements with rarely considering maintenance issues for products life-cycle. This paper presents an approach to nondestructive selective disassembly planning for the product maintenance. The approach is based on the part disassemblability analysis. It provides a way to support interactive selective disassembly task planning in dynamic manufacturing environments considering the operation space in applications. To support design at the early stage of product development, this paper also discusses de-manufacturability and maintainability analysis based on the proposed approach. Examples are provided to verify the developed method.

Abstract:
In this paper, an innovative method is presented which uses the properties of atomic theory to solve design modularization problems for product design. With the developed method, products can be modularized based upon different given constraints, e.g., material compatibility, part recyclability, and part disassemblability. The developed method can help engineers effectively create modular designs in the initial design stage, based upon different design requirements. With design considerations incorporated into new modules, a new design can be created which improves upon an original design, with respect to design requirements.

Abstract:
Abstract Industrial companies are facing more pressure to improve the recyclability performance of their new designed products. The concept of Environmental Conscious Design (ECD) has been adopted to assist more concerning about the environmental impact of the products at the early stage of designing. This new trend requires that the design strategy should be modified to integrate environmental constraints. This paper develops an Environmental Design Support Tool (EDST) to help designers improve their product in aspect of the environment. The proposed EDST is capable of evaluating the new designed product in terms of environmental sustainability, i.e., material selection, recyclability evaluation, and disassemblability analyses.

Abstract:
In recent years, environmentally conscious design has become a fundamental approach for industries which have to consider the variable environment during the design process. Waste management is one of the most important aspects to be handled, to reduce the disposal in landfills and to encourage the sustainable 3R approach: Reuse, Recycling and Remanufacturing. Product disassembly is an essential phase of the product lifecycle, necessary to evaluate the End-of-Life (EoL) strategies and to reduce environmental impact. In order to minimize the impact on production and costs it is very important to consider EoL scenarios during the embodiment design phase, when designer’s decisions influence product structure. Design for Disassembly (DFD) is a powerful method to reduce disassembly time and costs. However, there are no useful tools which provide guidelines to improve the product disassemblability or promote specific EoL scenarios. For these reasons this paper describes an innovative Design for Disassembly approach and related tool to support designers in product disassemblability evaluation. The tool has the scope to manage EoL scenarios for industrial waste in the early design phases and to share metadata with the traditional design tools. Disassembly costs is one of the most important parameters during the evaluation of EoL scenarios. Six indices are presented to evaluate the economic and environmental feasibility of the EoL strategies. The calculation of the six indices permits alternative EoL scenarios to be compared and encourage the recyclability, reusability or re-manufacturability of a product. These evaluations can be used to foster a particular EoL scenario, as early on as in the design process. The preliminary analysis on mechatronic products underline the utility of the software tool and indices. Product re-design, realized using this approach, shows a relevant decrease in environmental impacts and disassembly costs. As a consequence, the new product has a relevant percentage of components with a closed-loop lifecycle.
