In Bangladesh, the major challenges in producing highly customized products like prosthetics are the fulfillment of the demand in least possible time and cost. This study aims to mitigate these problems associated with the concurrent production system by incorporating Cloud Based Design and Manufacturing (CBDM) which refers to a service-oriented collaborative product design and development model where service consumers are capable of selecting, configuring, and utilizing customized product manufacturing resources and services ranging from computer-aided engineering design software to rapidly reconfigurable shared manufacturing resources. The study includes an overview of the current situation of prosthetic production and the possible benefits and challenges of CBDM implementation in Bangladesh. It also presents a comparison between three production models for transtibial prosthetic in perspective of Bangladesh including traditional, combined and CBDM method depending on production time, capacity and unit product cost. Approximate production time and capacity is determined by simulating each model in ARENA simulation software and unit product cost is calculated by conventional costing method. Analysis of these production models has proven CBDM to be helpful in transtibial prosthetic production when incorporated with the traditional manufacturing process resulting in achieving higher capacity, shortest delivery time and least possible cost which can provide a promising approach to implement CBDM in Bangladesh in the future.
