Each work center has a capacity, expressed in hours, that it can perform on a given day. The total number of processing hours available at a work center on a particular day is defined for each day of the week using the Standard Hours Available in Work Center field in the Work Center Maintenance window. This information can be modified by the shop calendar for holidays and other days when the work center is not available.
The standard hours available can be further modified using the Efficiency Percentage field in the Work Center Maintenance window. This percentage is used to reflect maintenance problems and other factors that can reduce the actual production capacity. If a work center is working at full capacity, this field should be set to 100 percent. For scheduling purposes, the number of hours available for production at a work center is calculated as follows:
(Standard Work Center Hours for Day x Work Center Efficiency Percent) / 100
Example
Assume that a work center consists of two identical machines and has a capacity of 16 production hours per day. If one of the machines breaks down, the work center is only able to produce for eight hours per day. The work center efficiency percentage should be set to 50 percent to reflect this loss of capacity.
