“…Step 4. Obtain combination weights using the least square method Absolute importance 2, 4,6,8 Middle value between the two adjacent judgment Based on the subjective weights S 1×8 (s j ) and the objective weights W 1×8 (w j ), the least square method is applied to determine the combination weights as shown in Eq. 12.…”

“…It is increasingly hard to ensure the durable and stable operation of products under complex working conditions, which sets a higher request to the maintainability of product. Product design can greatly affect the entire life cycle of a product, and the maintainability of product usually has been determined approximately after the finish of design stage [5,6]. As a result, the maintainability should be fully considered in product design, and thus product maintainability design is very important and essential.…”

Disassemblability evaluation is an important part of product maintainability design. Currently, the disassemblability evaluation of complex products is not systematic and complete. The main problems include (1) the existing methods are limited to individual components, ignoring the evaluation of the whole product; and (2) most studies focus on the single disassembly operations rather than a complete process. To address these problems, this paper proposes a hierarchical and process-oriented evaluation framework. Firstly, from the levels of component and product, a two-level evaluation index system is constructed, and the selected evaluation indexes reflect the features of both current operation and previous disassembly process. Secondly, based on Look-up Table, virtual maintenance, and simple algebraic operations, the evaluation indexes are quantified successively. Thirdly, a hierarchical evaluation procedure is presented, which includes two levels and four types of evaluations. Based on the synthetic application of different types of evaluations, the disassemblability of a product can be fully evaluated and understood. Finally, the effectiveness of the proposed framework is verified by a case study of an electronic cabin.

In the past few years, there have been some significant advances in consumer virtual reality (VR) devices. Devices such as the Oculus Rift, HTC Vive, Leap Motion™ Controller, and Microsoft Kinect® are bringing immersive VR experiences into the homes of consumers with much lower cost and space requirements than previous generations of VR hardware. These new devices are also lowering the barrier to entry for VR engineering applications. Past research has suggested that there are significant opportunities for using VR during design tasks to improve results and reduce development time. This work reviews the latest generation of VR hardware and reviews research studying VR in the design process. Additionally, this work extracts the major themes from the reviews and discusses how the latest technology and research may affect the engineering design process. We conclude that these new devices have the potential to significantly improve portions of the design process.

“…In other words, despite understanding the importance of such a subject, the literature provides inadequate guidance for a product development engineer towards the understanding and assertiveness demanded for delivering maintainability demands/expectations, from the conceptual phase and through to the embedding into the final product. According to Peng et al (2012), thoughtful consideration of maintenance features early in the design process may reduce or eliminate maintenance costs, promote lower downtime and improve safety aspects.…”

Purpose The purpose of this paper is to provide a new approach involving guidelines and supporting techniques that guarantees all needed space for appropriate product maintenance. Design/methodology/approach The approach is based on two major areas: field survey to understand how maintainability parameter is applied and converge theory and practice into a systematic space claim method using computer-aided design (CAD) systems to assure proper maintenance procedures at design stages. Findings Case studies from a truck industry conducted following the proposed approach contrast the savings that can be achieved by using a proper space claim for aftermarket needs against an unsuitable level of participation by maintenance personnel during the design development. Research limitations/implications This approach is highly dependent on maintenance experts with suitable skills on CAD systems. Practical implications Products developed according to the approach envisaged can result in following aspects: lower repair time, better maintenance procedures on key components, easier preventive maintenance, less need for special tools, more ergonomic design, better communication between design and service engineers, simplicity and less complex training. Social implications Further research on maintainability will provide new information on how to apply this parameter on product development process (PDP), so design teams can better understand and address this relevant issue. The proposed method has been introduced in the PDP of a major multinational automotive company. Originality/value A new process is presented, considering the protection of needed spaces for maintenance procedures throughout the PDP, diverging to other studies that only propose analysis addressing maintainability at singular point in time during the product development. In just one case study presented, savings of US$1.3m were achieved by applying this space claim approach.
