Production planning in an apparel company and optimization

In our country, most of apparel companies are the subcontractors. As they don?t produce fashion and have their own brand name, they supply fabrics fully depending on their customer demand. Time compression fo r these make to order companies force them to work with many fabric supplier without a proper selection. As a result, they face quality and delivery problems time to time.In this study, working model containing fabric supplying for most used fabrics without collecting order in heaviy working season, is proposed for make to order apparel subcontractors. The proposal is tested with simulation method. At the end of the trials, it is concluded that with the proposal working model, the decrease at lead time for fabric supplying is statistically significant, the total cost of the new working model is less than the cost of the current working model because of the decrease at transport and order costs.As the all results are taken into consideration, it is decided that the feasibility of the proposal working model can be argued.
