Capacity Planning-Techniques (Capacity Bills) Capacity bill is a rough-cut method,providing more direct linkage between individual end product in MPS and the capacity required for each work centers; considers any shifts in product mix; requires more data than CPOF:not only BOM and routing date are,but also direct labor-hour or machine-hour data. Calculation procedures: First calculate bill of capacity of end product,that is total time/unit for each end product on each resource,based on BOM,routing data,direct labor-hour or machine-hour; Then,apply bill of capacity to MPS to obtain capacity requirements of each resources in each period; 上浒充通大粤
