Integer Quadratic Programming (IQP) Model for Cut Order Plan

Abstract

In the apparel industry Cut Order Planning (COP) considered as the most important procedure in the production process. Cutting large number of pieces with different shapes and sizes should be well planned to increase the utilization offabric while reducing the wastage. Therefore cut planners pay great deal of attention to the number of plies, size ratios, length of the fabric, the cost of labour and they highly concerned about fabric wastage. This procedure is carried out manually in most o f the factories. Due to that, high cost o f labour, time and the fabric wastage have become more crucial problems in this industry. The existing manual procedure for COP was examined in this study and to overcome those issues an integer quadratic programming model was introduced for two and three dockets. As a result of this new model, user will receive number of plies that can be laid and size wise cutting templates that requires for the cutting process in order to minimize the cut panels wastage. Eventually this causes to increase efficiency and effectiveness o f the cutting process more significantly
