joint scheduling and available-to-promise calculation in make-to-forecast production systems

making a rational decision about the free production capacity of a firm requires accurate and comprehensive information in different fields such as unscheduled time of the machines, materials or other required resources status in the firm and the related supply chain. in this study, we try to achieve the needed information through integrating advanced available-to-promise mechanism with scheduling in flow shop production systems. the aim is to determine the scheduling of the orders simultaneously with calculating the free capacity of the system to determine the atp. therefore, some different kinds of constraints including the availability of the machines and materials are considered. the obtained results from solving the proposed model lead to proper values for performance indexes.
