【正文】 quantity) – Sort prioritized demand orders – Sort parts from enditem to raw materials – Calculate demands – Allocate supplies ICP Inventory Assignment (cont.) ? Forward Schedule – Definition: Earliest Possible Start Time (EPST) the earliest date that a manufacturing task can begin (constrained by materials) – EPST = max (Server Start Time, Material Available Time) – Calculates the EPST for each manufacturing task – Each manufacturing task will have an EPST – Hard constraint: production cannot be started without materials available ICP Inventory Assignment (cont.) Sub assembly 1 . 1 . 2 Computer Order Completion Time Material Available Time (EPST) EPST EPST Mfg order 1 Mfg order 3 Mfg order 2 ? Forward Schedule Sub assembly 2 ICP Planned Start Time ? Assign PST for each task ? Definition: Planned Start Time (PST) is the expected start date that a task will begin taking material availability into consideration ? Calculation: PST= max (EPST, LPST) ? Each manufacturing task will have a PST ? PST values may be overriden through the user interface ICP Capacity Utilization ? Determine bucket (operation time interval) configuration from variable capacity bucket size data ? Calculate capacity for each bucket from resource calendar data ? Calculate work load in each bucket based on PST and run time of each task FP Finite Capacity Planning ? Identify the constrained resources ? Balance and offload loads for constrained resources in a GLOBAL view (Global optimization) ? Plan based on flexible strategy options (. Minimize WIP) ? Respond quickly FP Detail Scheduling ? Schedule based on flexible st
