Simulation Modeling of Sewing Process for Evaluation of Production Schedule in Smart Factory
Simulation Modeling of Sewing Process for Evaluation of Production Schedule in Smart Factory Industrie 4.0, proposed by DFKI [1], is defined as the 4th industrial revolution based on Internet-of-Things (IoT) [2], cyber-physical systems (CPS) [3], and Internet-of-Services (IoS) [4]. One of the characteristics of Industrie 4.0 is that it includes smart factories capable of generating customized products for customers. One of the important issues to implement a smart factory is to complete and deliver customized products to customers within specified time. For this, we need an efficient scheduling algorithm [5]. It becomes more and more sophisticated work to validate a production schedule in factories. Simulation is a tool for validating a production schedule and changing it if needed. For using simulation, we need appropriate simulation models. In this paper, we propose a sewing machine model for simulating sewing process. The proposed sewing machine model includes sensing, sewing, forw...
