Waste Electrical and Electronic Equipment (WEEE) is one of the major waste streams in terms of quantity and toxicity, and a critical step in WEEE end-of-life (EoL) processing is through disassembly. Compared with full disassembly, which is a sub-optimal solution due to its high operational cost, selective disassembly is more economic and practical as only selected parts with recycling potential are considered. In this paper, a systematic selective disassembly approach for handling WEEE with a maximum disassembly profit in accordance to the WEEE and Restriction of Hazardous Substances (RoHS) Directives has been developed. Firstly, a space interference matrix is generated based on the interference relationship between individual components in the 3D CAD model of WEEE. A matrix analysis algorithm is then applied to obtain all the feasible disassembly sequences through the obtained space interference matrix in a 3D environment. Secondly, an evaluation and decision-making method is developed to find out an optimal selective disassembly sequence from the obtained feasible disassembly sequences. The evaluation takes into account the disassembly profit and requirements of the WEEE and RoHS Directives, which regulate on recycling rates of different types of products and removal requirements of (i) hazardous, (ii) heavy, and (iii) high-value components. Thus an optimal solution is a selective disassembly sequence that can achieve the maximum disassembly profit, while complying with the WEEE and RoHS restrictions based on a brute-force search method. Finally, an industrial case on Changhong Liquid Crystal Display Televisions (LCD-TVs) of the type LC24F4 is used to demonstrate the effectiveness of the developed approach.

“…Smith and Chen present a disassembly approached based on the geometric relationships between components, rather than geometric constraints for pairs, the proposed algorithm being recursive and based on five rules defined to eliminate unfeasible or unrealistic sequences [Smith, 2011]. Therefore, not all the possible disassembly solutions are generated, the optimal disassembly path being evaluated using a cost function.…”

The paper presents the development of a new software tool integrated with SolidWorks CAD system for generating feasible disassembly directions based on the concept of mobility operator. In generating the disassembly path of a component, our approach considers that two steps should be undertaken: first, the interface between components is broken and then the component is extracted from the assembly by translating it along a collision free removal path. Different data from the CAD model of the assembly is automatically detected, such as: geometrical constraints, contact surfaces relative position, common area, components neighbours, etc. Based on this information, a general mobility operator is deployed, which is further used to evaluate the families of trajectories associated to the contacts between different components of a mechanical system. Thus, the developed mobility operator mathematically expresses all possible movements between assembly components (rotations, translations and helical movements), and it can be used for a real time graphical representation of components mobilities, mandatory aspects in developing a virtual environment for simulating the Assembly/Disassembly (A/D) tasks as part of an efficient Product Design Process (PDP).

“…The key point for an effective application is to gain a balance between the human body capacities and the task demands [14]. A method to evaluate the quality of disassembly sequences by choosing the optimal one is presented in [19]. It is based on a cost function which calculates the cost value of each disassembly sequence.…”

Today disassembly operations play a very important role during the initial design phase of industrial products considering the role played by these operations throughout the Product Life-Cycle (PLC). The available disassembly evaluation methods seldom make disassembly as the preferred end-of-life solution for the reuse of parts or components in an economically sustainable way. This paper deals with a new method for disassembly sequences evaluation by muscle fatigue and metabolic energy expenditure estimation. It is based on four hypothesizes for building the equivalence between the metabolic energy expenditure of the human arm during disassembly operation simulation and corresponding muscle fatigue developed in the operator's arm muscles. For this purpose, the mechanical energy expenditure on operator's arm is involved to evaluate the possible disassembly sequences. The proposed method is validated by a set of experimental tests performed in a Virtual Reality environment. The results of the analysis and findings show that the mechanical energy expenditure can be used to evaluate the disassembly sequence by considering the human muscle fatigue factor while performing disassembly operation simulation.
