Analysis of machine interference problem with simulation technique in knitted fabric production

The aim of this study is to minimize machine downtimes and costs by using simulation technique in order to increase productivity in knitting industry. For this purpose, real data belonging to a knitted fabric manufacturer were examined. Subsequently, one-year orders were filtered using the company's own software, and the most received orders were determined. According to the orders in question, machine stoppages, types of stoppages and response times to stoppages were recorded with a time study, and a simulation model was created by transferring the relevant information to Simul8 software. After the validation of the composed model, alternative models were created and various efficiency and cost analyzes were performed. Suggestions were made on the number of machines that an operator should pay attention to for different types of orders.
