Case study of physical internet for improving efficiency in solar cell industry

In a solar cell industry, cells sorting and product information frequently result in shipment errors and customer complaints. Solar cells are sorted through a process of efficiency and chromatic aberration testing, during which parameters such as output power, colour, and retest frequency are applied to sort the solar cells according to approximately 90 types of specification. During the process of sorting solar cells, operators verify the specifications and classification manually. However, such a process often generates complicated identification problems. Therefore, this paper presents a case study of implementing physical internet platform including automatic product identification system, product tracking system, finished product scan and pack system, and electronic shelf system. Moreover, using the proposed platform can reduce operational costs, improve operational efficiency, and increase the competitiveness of the company.
