9、art Numbers,Mfg Orders,Rhythm FP Planning Concept,FP Planning Concept,BTO(Build-to-order)engine:use,Demands,as the driver to create plan,Consider both material and capacity constraints at the same time,Consider both,Sales Orders,and,Forecasts,as the demand input with different priorities,Start as an

10、,Infinite Capacity Plan,and progress to a,Finite Capacity Plan,FP Planning Concept,(cont.),Materials are assigned according to the BOM explosion from the finish good level,also consider Time factors,Raw Materials(Procured Parts)are supplied by on-hand inventory or P.O.from vendors.,Manufactured part
