The webinar will draw on white paper “Model This!!!” and Utility Risk Modeling to illustrate using Pert distributions to model complex demand curves and discrete distributions to model solar and wind supply curves. Material Requirements Planning is an inventory control system to ensure that parts are delivered for a known master schedule. But what if the master schedule, that is future demand, is not fixed, but stochastic. RISKOptimizer can be used to determine order quantity and the trigger point for ordering that both minimize inventory and avoid stockouts as covered in the white paper “MRP”.
