【正文】 21 Finite capacity Resource grouping for Production planning 169。D’s exclusive use. MANUFACTURING PLAN The planners generate the production reports using the manufacturing data of the first three weeks. Planner only releases the manufacturing orders that begin in the next two days in the manufacturing execution system. Normally planners only release work orders when the materials of work order are all ready in the inventory. But in some urgent cases, they also release the work order even when not all the materials are all ready. The shortage material may be arriving within the following two days. Work orders for special AI are released when the actual sales orders are received. 169。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL Ramp。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL Note that PTO at the top of the BOM is a packing process, and does not have any routing. The sales order line item will be at ATO level. SMT factory is in the MTS mode, producing according to forecast. There is a SMT inventory warehouse for SMT boards. ATO factory perform the final assembly and testing when Huawei receives the order. In simple words, ‘Planning at the ATO level’ is ATO. The ‘Planning at the SMT level’ is MTS (Made To Stock). ATO’s are unique to customers whereas SMT’s are not. Thus, multiple unique ATO’s share mon SMT. MDS In MDS phase, planners gather all the forecasts first. Then check and adjust the forecasts. After confirming the forecasts, the planners gather all the demands together, that mainly ing from the following four ways a. Demands from marketing plan department b. Demands from the business department (real sales orders) c. Internal demands between different departments d. Independent requirements from different departments After this phase, planners know all the demands that needed to be planned. MPS To generate MPS, planners first generate a MPS plan and get the relation reports. Then they adjust the MPS result before sending to the planning manager for approval. After the planning manager confirmed the MPS result, the planners need to maintain the new MPS plan. Then the MRP scheduling plan is generated. When adjusting the MPS plan, the planners consider the five factors below: a. Version change b. The capacity constraint of the key resources c. The requirements change from the marketing, and changes in internal requirements 169。 factory will schedule other nonconstraining resources as well as the operators. FP outputs the production plan including WIP back to MP as its supply. Based on a feasible material and capacity, FP sends material requirement forecast, and procurement remendation for all planned parts to SCC for collaboration. Exceptions such as material shortage and expedition remendations are also provided to the buyer. FP also outputs JIT/VMI pull signal based on near term production schedule. OVERVIEW OF OPERATIONS – AS IS PROCESS OVERVIEW OF BUSINESS PROCESS At HUAWEI the planners of different department are in charge of materials planning. And the planners only plan the products for their own department. All the planning processes are separately. The whole process is: a. Gathering and process all demands with MDS (M b. Generate MPS c. Run MRP and Scheduling d. Process WO and PR e. Execute WO and PR 169。D, as well as internal demands. The The anization involved in the scope of Phase I is Huawei’s factory in ShenZhen for all the product divisions. This phase will enable the HW ShenZhen factory to: ? Provide material requirement forecast planning for all planned procured parts up to 1218 month ? Plan material based on the feasible production plan up to 46 months, or the longest leadtime for noncritical material ? Improve demand due date performance by reviewing early warning of late orders and material shortage ? Plan for alternate ponent requirements ? Generate production plan over the planning horizon, and production schedule for the frozen period. 169。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL REQUIRED APPROVALS.............................................................................. 59 169。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL CONSUMPTIONS .................................................................................... 23 BUSINESS SCENARIO DETAIL: FP11.
