【正文】 ................................ 58 MAJOR CHANGES SINCE LAST REVISION .................................................. 58 169。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL PURPOSE The Business Analysis document captures the AsIs Process, identifies improvement opportunities and defines the ToBe Process. It also documents business scenarios that describe the workflows and business processes that the software solution should address. It elaborates on the available inputs, required processing (including timing and frequency considerations) and the required outputs. Each scenario in turn helps in defining what solution features would be required. The document is a supporting tool to decide on the features and functionality needed in the solution. The use case scenarios are later used to validate and accept resolved issues. The document should be used at the start of the Solution Architecture phase, and continually reviewed throughout the implementation as more information bees available. The ToBe Process Map is a separate document available in i2 Project Document Library for Huawei project. SCOPE OF THE IMPLEMENTATION 2020 GO LIVE As a module in the APS solution, FP perform material and capacity planning, as well as factory scheduling for HW. FP plans for all demands in HW, including customer orders, forecasts, Ramp。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL ? Provide visibility into material and capacity problems ? Better supply to demand match to reduce inventory level Planning horizon will be 6 months that starts with daily buckets for the first two weeks, followed by weekly buckets for the next month, and then followed by monthly buckets. For the monthly run of FP to generate master material requirement planning, up to 18 months of forecast can be used. FP generates procurement plan only for noncritical ponents. MP generates the procurement plan for critical ponents. From MP, the constraint forecast demand (AI and POC) as well as the critical material supply would be the input to FP. FP will perform the factory level detailed material planning for all ponents, as well as all the major bottleneck resources. Scheduling will also be performed on the bottleneck resources. Use the FP schedule result as a base。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL A cc e p t c o n t ra ctM a kc CCPE n t e r o rd e rM a k e CCDPM a t c h R e so u c eR e l e a s e w / oE x e cu t e w / oC a p t u re o r d e rC a p t u re F C S TC a p t u re i n D M TD e ve l o p M D SD e ve l o p M P SR u n M R PP ro c e ss S A w / oP ro c e ss PRE xe c u t e S A w / oE xe c u t e PRS h o r t a g e M e s s a g eA v a i l a b i l i t y M e s s a g e The Billofmaterials for a typical Huawei sales order item is as in the following figure: PT O POC_ 1 A T O SM T_1 SM T_2 Othe r items Ra w _1 Ra w _2 Ra w _3 PT O: Pa c k to order No m an ufa c turi ng o rder be t w ee n A T O an d P T O.

Purchasing forecast There are two types of purchasing forecast, one is weekly forecast, and the other is monthly forecast. Weekly forecast covers three months purchasing forecasts. The materials 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 released. ? The MAX/MIN method allows MAX and MIN inventory for the materials. When the material’s inventory is lower than the MIN value, they will be purchased use the following formula: Purchase quantity = MAX – Inventory – PO (time based) + Required quantity of sales order (time based) 169。D material planners manually plan and enter the PR of the material for Ramp。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL BUSINESS SCENARIOS Introduction: Based on the interview questions and discussions with Business Units process owners and factory schedulers, various business scenarios that represent FP’s business requirements have been piled.
