A Blockchain-Based Quality 4.0 Application for Warehouse Management System

In today's competitive conditions, firms compete in every aspect. It is essential to meet the quality requirements in all processes and to meet customer needs quickly. It should be ensured that all processes in the enterprises, all the technology used, and all the workforce employed are included in the total quality of the enterprise; necessary controls and corrections are made; and the quality is sustainable. In this study, (1) one of the critical processes of an enterprise, the process of a material arriving at the warehouse after its procurement and the process of its storage in the warehouse, is discussed. (2) The basic processes in storing raw materials or finished products have been redesigned based on quality with the help of the Blockchain (BC) method from Industry 4.0 (I-4.0) technologies. (3) A model has been developed for the BC-based Quality 4.0 (Q-4.0). This model was applied to the warehouse management processes of an enterprise and compared with the enterprise's existing system. (4) As a result of the comparison, it has been seen that the developed Q-4.0 model is more effective and more comprehensive. (5) Due to the originality of the developed model, such a study is not encountered in the literature.
