Production planning and scheduling are generally treated sequentially. Based on a critical review of the application of simulation techniques to Production Planning and Control (PPC) problems between 2002 and 2014, the literature was systematically narrowed from about 2,250 to 131. The five problems considered in PPC are facility resource planning, capacity planning, work planning , process planning and production scheduling. The development of expert systems in scheduling poses many problems and many different approaches have been tried in prototyping systems. One of the manufacturing companies that produce polycarbonate lenses applies a make to order system. Based on the production scheduling that has been applied, the order completion target has not been met for 30 days. Based on the problem in production scheduling, analyzing by production scheduling and line balancing for polycarbonate lens production. So it can meet the target completion of orders that have been set.
