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 recommendation for all planned parts to SCC for collaboration. Exceptions such as material shortage and
5、 expedition recommendations are also provided to the buyer. FP also outputs JIT/VMI pull signal based on near term production schedule.OVERVIEW OF OPERATIONS AS IS PROCESSOVERVIEW OF BUSINESS PROCESSAt HUAWEI the planners of different department are in charge of materials planning. And the planners
6、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 (Mb. Generate MPSc.

9、, PROPRIETARY and CONFIDENTIALNote 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 perfo
10、rm 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). ATOs are unique to customers whereas SMTs are not. Thus, multiple unique ATOs share common SMT. MDSIn MDS phase, planners gather
11、all the forecasts first. Then check and adjust the forecasts. After confirming the forecasts, the planners gather all the demands together, that mainly coming from the following four waysa. Demands from marketing plan departmentb. Demands from the business department (real sales orders)c. Internal d
12、emands between different departmentsd. Independent requirements from different departmentsAfter this phase, planners know all the demands that needed to be planned.MPSTo generate MPS, planners first generate a MPS plan and get the relation reports. Then they adjust the MPS result before sending to t
13、he 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 changeb. The capacity constraint of t
14、he key resourcesc. The requirements change from the marketing, and changes in internal requirements 2001 i2 Technologies, PROPRIETARY and CONFIDENTIALd. The planning percentage e.

The mat
16、erials are mainly locally supplied. And the purchase lead time are relatively short. Some examples are packaging materials, PCB etc.Monthly forecast covers nine months purchasing forecasts.Special materials are only purchased when the real sales orders are received. They are manually managed and rel
17、eased. The MAX/MIN method allows MAX and MIN inventory for the materials. When the materials inventory is lower than the MIN value, they will be purchased use the following formula:Purchase quantity = MAX Inventory PO (time based) + Required quantity 2001 i2 Technologies, PROPRIETARY and CONFIDENTIA
18、Lof sales order (time based)R&D material planners manually plan and enter the PR of the material for R&Ds exclusive use.MANUFACTURING PLANThe planners generate the production reports using the manufacturing data of the first three weeks. Planner only releases the manufacturing orders that begin in t
19、he 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.
