What is IoTs

In this work, the authors design a combined system of blockchain and value stream mapping (BVSM) to monitor and improve production processes. The proposed blockchain value stream mapping (BVSM) system not only captures real-time performance but also helps to improve the performance of the manufacturing process. The transparent, immutable, decentralized, and accurate blockchain information is transferred to the value stream mapping (VSM) system to reflect dynamically the status of the manufacturing process. All changes in the production process are continuously monitored to help managers quickly make appropriate improvement decisions. Two case studies of a garment company in Vietnam and a JCB factory in India from a reference are used to illustrate the implementation of the proposed BVSM system.
