Development of Service and Product Design Processes Considering Product Life Cycle Management for a Circular Economy

One of the purposes of a circular economy is to reuse repeatedly products to extend their useful life and ultimately to be returned to nature. Therefore, following the concept of the circular economy, we need to previously design the process of reuse and remanufacturing of products to repeatedly reuse the products. In this research, we develop a service and product design process considering product lifecycle management in the circular economy. First, we inspect the characteristics of product design to realize the circular economy with reference to papers discussing the circular economy. Then, we propose the table based on a journey map to create processes to reuse a product. In addition, we propose service design method using IoT/DX systems for enhancing reuse of products, and explain the effectiveness of the developed method.
