In today’s fashion trends has growth and impact to manufacturing footwear industry competitive especially for Make-to-Order (MTO) companies. For MTO companies order scheduling are driven by customer orders and production resources availability. Successfull order scheduling can responsive to fulfill customer demand based on due date. In literature, order scheduling in multi mixed-model production environment some companies has assign fix model to each assembly line which will make the result trapped in local optimization. So, in this paper we purpose order scheduling which assign flexible model to each assembly line in order to get global optimization in the final order schedule. A flexible order scheduling in footwear industry concurrently need to considered production resource share between production line include tooling and machine share because company has limited resources. Finally, practical case problem of flexible order scheduling in footwear industry is solved with the proposed scheduling model development by design multi objective function consist of minimizing penalty cost, minimizing makespan, maximizing line efficiency and minimizing total frequency of model changeover with the consideration of production resources availability. Result of order scheduling model development is order allocation and order sequence.
