Problems solved by technology

[0004] However, because the MRP system mainly makes inventory management decisions based on BOM requirements, it does not consider multiple factors such as enterprise manpower and production capacity, which leads to continuous large MRP material demand forecasts and high inventory levels; in addition, the system cannot be based on special business scenarios. Perform algorithm optimization

Embodiment Construction

[0030] In order to make the object and effect of the present invention clearer, the method of the present invention will be described in detail below.

[0031] The structural model of a general storage system can be expressed as figure 1 form. Due to the demand of production or sales, a certain amount of stock goods is taken out from the storage point, which is the output of the storage system. And when the continuous output of stored goods leads to the continuous reduction of the quantity in the warehouse, the enterprise must take appropriate replenishment behaviors in time, which is the input of the storage system. As for the demand in the system, the mode of demand can be uniform continuous or intermittent batch, and the quantity of demand can be deterministic or random. Replenishment can be in the form of business units ordering from outside or arranging production activities by themselves. The main quantitative indicators for researching replenishment are: determining ...

Abstract

The invention discloses a material demand weighted prediction method based on enterprise MRP. The method comprises the following steps: firstly, determining a minimum material purchasing period T anda material purchasing advance period LT, and obtaining multi-dimensional data such as daily inventory, ex-warehouse and MRP; secondly, based on historical daily real ex-warehouse data, calculating byusing a moving average method to obtain an average value Davg of purchasing advance demand DLT; calculating the ratio distribution of the historical demand average value Davg to the historical daily MRP data, and respectively obtaining a maximum value rmax and a minimum value rmin; calculating an actual weight Wave and an MRP weight Wmrp according to the ratio rt of the historical demand average value Davg to the MRP of the current test day; and finally, the model estimates a purchase advance demand DLT and a minimum purchase cycle demand DT based on the weight coefficient to complete demand prediction. According to the method, the weight coefficients of the MRP data and the historical warehouse-out rule are designed for demand prediction, so that the defects of the MRP are greatly improved, and a scientific reference basis is provided for enterprises to purchase materials.

Description

technical field [0001] The invention belongs to the technical field of information forecasting, and specifically designs a material demand weighted forecasting method based on enterprise MRP. Background technique [0002] In the activities of production, operation and commodity sales, enterprises often need to store the purchased raw materials, produced products and sold commodities for use and sales. However, real business scenarios are highly complex, and the inconsistency between demand and supply, consumption and storage will directly lead to an unbalanced state of supply and demand. On the one hand, it may cause a backlog of materials, resulting in slow capital turnover and increased inventory costs; on the other hand On the one hand, due to the shortage of materials, production stoppages or out-of-stock sales have caused economic losses to business units due to reduced profits. [0003] In order to effectively improve the efficiency of inventory management, the materi...
