The rate at which work is withdraw from the system. ? The highest reasonable output rate which can be achieved with the current product specifications, product mix, work force, plant, and equipment. [APICS dictionary] 19 Capacity Management ? The function of establishing, measuring, monitoring, and adjusting limits or levels of capacity in order to execute all manufacturing schedules. [APICS dictionary] ? Include – capacity planning – capacity control 20 Work Center and Load ? Work Center – A specific production facility, consisting of one or more people and/or machines, which can be considered as on unit for purposes of capacity requirements planning and detailed scheduling. [APICS dictionary] ? Load – The amount of scheduled work ahead of a manufacturing facility, usually expressed in terms of hours of work or units of production.

Demonstrated (Measured) Capacity – the average recent output actually achieved , is figured from historical data – is defined as average output, not max output ? Rated (Calculated) Capacity – available hours utilization efficiency 26 6% 6% 62% 13% 13% Breaks R. Maintenance Run Time Unutilized but scheduled time Setup Time Utilization Actual time used (run and setup) Scheduled time intended for production Utilization = A measure of how intensively a resource is being used…. 27 Utilization Example: Breaks: 20 minutes per shift Routine maintenance: 10 minutes per shift Run time charged: 6 hours Setup time: hour Utilization = 28 Efficiency ? A measure of how closely predetermined standards are achieved. Actual output (standard hours earned) Standard output expected (scheduled) efficiency = 29 Efficiency Example: Work center: 3 machines, two 8hrs shifts, five days a week Breakdown: 12 hrs per week Utilization = records indicate that the work center produced an average of sta. Hours of output. Efficiency = Capacity = 30 Capacity Determination Shift per Day ? Machines or Work Stations ? Hours per Shift ? Days per Week ? Utilization ? Efficiency = Standard Hours per Week Ex: Shifts = 3 Shift Length = 8 hrs 5 Days per Week Number of Machines = 6 Machine Utilization = .8 Efficiency = .9 31 RoughCut Capacity Planning ? The need for long planning horizons and the lack of specific, accurate data for many important factors make RCCP techniques more practical than detailed calculations ? A capacity plan should not be deferred。 ? 不是為了作為途程 (Routing)用途。 前置時間 : 2期間 0 1 2 3 4 5 6 7毛需求排程到貨預估在手量計劃核發(fā) 4 0 0 料件 121固定數量訂購 。 18:52:3818:52:3818:52Thursday, Febru
