“…Efforts to address this issue are usually pragmatic, such as making decisions based on the availability of materials; any further complexity is only considered if complications arise from the default choices. In the present-day, knowledge bases about these decisions have been implemented in decision-making and simulation software to reduce time spent on deliberation [8].…”

Prostheses are intended to restore the human body's appearance and return some functions lost due to the loss of limbs. The prosthesis industry exists for this purpose, as well as the servicing of the prostheses. However, there are complications in the design and installation of prostheses, as well as servicing them. Prosthesis usage is subjected to the specific circumstances of the recipient and is dependent on medical coverage for long-term servicing. The relatively low number of cases involving prostheses compared to other medical cases and the circumstantial differences between these cases prevent in-depth and comprehensive studies of the industry, preventing the establishment of standardized best practices. Despite this, research and development of improvements for recipients' problems continue, utilizing the latest technologies to address technical complications. This article consolidates the present-day complications of prosthesis making and servicing.

“…The ELECTRE methods follow the goal of outranking a definition closely while PROMETHEE methods are based on a pairwise comparison of alternatives. There have been many ELECTRE methods reported such as ELECTRE I, 66 ELECTRE II, 5 ELECTRE III, 67,68 ELECTRE IV, 4 ELECTRE TRI, and ELECTRE IS. Each of the ELECTRE versions differs operationally and is respective to the types of problems.…”

“…Similarly, other researchers applied ELECTRE III in their material selection problem for the same reason. 68,70,71 Also, the selection of sensitive material components needs to be realised as a teamwork task in enhancing the reliability of the chosen material. With disagreement in design preferences sometimes encountered, Shanian et al 70 introduced a decision matrix with a revised Simos method in defining a set of weighting factors and performed a stability analysis along the ELECTRE III on the material rankings for a bipolar plate application.…”

Technological advancements and the growing material set in the world have created a large variety of options for industrial designers, but little attention has been given to the tools and methods that support material selection processes. In this paper, we report on a comprehensive systematic literature review (SLR) guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement on methods or approaches reported for supporting material selection processes. This review covers various published literature, spanning from 2000 to 2018. The purpose is to examine in detail the evolution of the extensive body of research, its research streams and to position possible areas for further research. A classification framework consisting of six categories of selection approaches was derived from the extensive literature. Additionally, a detailed analysis of predominant approaches was presented along with their advantages and limitations with respect to the material selection domain. Taken together, the insights gained from this study may be of assistance to new researchers and practitioners who are looking for potential selection methods for their specific applications. The review also found that there is an increasing trend of research in recent years in the area of OR-based method application specifically on the multi-criteria decision-making supporting material selection processes.

“…DFM follows the DFA analysis, with the aim of ensuring the part can be produced using the chosen manufacturing method. In the case of the paediatric knee, the material selection was optimised using the ELimination Et Choix Traduisant la REalité (ELECTRE) III multiple attribute decision making (MADM) method as discussed in Mangera et al 14 Applicable manufacturing processes were then chosen based on those available at the research institute to enable local manufacture and reduce import costs. Semi-solid metal high pressure die casting (SSM HPDC) and investment casting are suggested for high and low volume production, respectively, and the components must be adjusted to suit the processes.…”

Design for manufacture and assembly is a critical step in the product design life cycle. In this study, design for manufacture and assembly theory was applied to the design of a polycentric paediatric prosthetic knee to resolve assembly and manufacture issues prior to product prototyping. Assembly time and efficiency prior and subsequent to design for assembly analysis was calculated. By combining redundant parts and improving the ease of alignment, orientation, and insertion of various parts through modification of part features, a 10.1% increase in assembly efficiency was achieved. Design for manufacture analysis was then performed for die casting of the component. Undercut features were removed and replaced with the use of standard components, reducing the assembly time of the component by reducing the complexity of parts. Proposed design changes were verified using finite element analysis to simulate the loading conditions of a polycentric prosthetic knee as per the ISO10328:2006 standard for methods of testing prostheses. An overall improvement of 13.6% in assembly efficiency was achieved after the design for manufacture and assembly analysis. The improvement is due to the decrease in assembly insertion time and eliminating small parts and parts in areas that were difficult to access. The reduction in assembly time will directly reduce the labour cost for assembly of the manufactured product. This case study illustrates how design for manufacture and assembly theory can be applied to the design of biomedical equipment to reduce the need for prototype re-work and the consequent costs.
