Differences between ASCP and MRP
|
MRP |
ASCP |
| Core objectives |
Materials |
Materials, production capacity, plan |
| Planning Procedure |

Multi-thread, multi-whole |

At one level, substitute materials are not considered. |
Multi-level, consider alternative materials |

KPI indicators (time period inventory level, supply level, gross profit rate, cost breakdown) |
| Priority Planning |
Only by date |
Multiple priorities |
Forecast and MDS are used to predict finished materials, while ASCP is used to predict materials.Http://www.dezai.cn/blog/

ASCP prediction levelLevel 1: Material Level 2: Material + customer level 3: Material + customer + manufacturing location Level 4: Material + customer + delivery location
Planned Order Batch rules affect the number of planned orders. The priority is as follows:Fixed supply days> fixed order batch> minimum order quantity> maximum order quantity> integer order quantity
Supply locks may occur.<1> supply without demand <2> there is a difference between the prediction of marketing materials demand and the forecast of production materials demand <3> tickets and purchase orders may be locked
Load/copy/merge production schedulesLoading sources: <1> Prediction <2> sales order <3> Prediction + sales order <4> multi-organization Plan Order <5> main production schedule
Demand Expansion: refers to the process of balancing demand and supply in material demand rulesExpansion mainly depends on the following factors: <1> materials to be purchased and materials to be made <2> quantity of purchased and manufactured parts <3> items to be purchased, time Point for warehouse receiving of manufacturing parts <4> time point when the self-made parts ticket to be purchased is opened
Prediction Interval TypeThe Prediction Interval Type indicates the time zone used for sales prediction. in the selected time range, specify the predefined Product Shipment and quantity type category: days, days, sales forecasts, periods, weeks, weeks, sales forecasts, periods, months, sales forecasts, intervals, item numbers, multiple interval types, can be used at the same time.
Routing rules for ASCP alternatives:
First check whether the main material has inventory-> if not, check whether the main material has a po before the demand day-> if not, check whether there is a po before the demand day-> if not, check whether the most preferred alternative material is inventory-> NO, the PO after the main material is caught-> NO, the PO with the highest priority to replace the raw material-> NO, the Plan ticket with the main material is checked whether there is any material to replace the search will be subject to purchase early impacts, the smaller the number, the higher the priority.
Factors influencing the accuracy of ASCP Prediction
1. Consider the historical sales status
2. Advertising, promotions, and other factors
3. Use other management mechanisms
4. Respond to demand changes in real time
