Problems solved by technology

[0002] At present, the demand planning management of spare parts for nuclear power plants is to integrate the procurement requisitions from multiple demands on site. Spare parts for nuclear power plants have the characteristics of large number of codes, long procurement cycle, and fragmented demand.
However, the existing manufacturing enterprises have a short procurement cycle and consume a large amount of consumption. According to the current spare parts demand management method setting, the demand can be met.
However, if the spare parts of nuclear power plants are set according to the current purchase demand date, it will not be able to truly respond to the actual needs of the site. Some spare parts with high urgency will not be able to arrive in time according to the integrated demand date. Some spare parts with low urgency will not arrive in time after integration Purchasing plans with demand dates will increase the risk of inventory backlog

Embodiment 2

[0044] The computer in this embodiment includes a memory and a processor; the memory is used to store computer programs; and the processor is used to execute the computer programs in the memory to implement the method for optimizing the procurement demand date of nuclear power plant spare parts as in Embodiment 1 above.

Embodiment 3

[0046] refer to Figure 2 to Figure 4 , the demand date setting needs to consider the reserved quantity on site (required quantity for on-site maintenance work) and the reserved demand date (required date for on-site maintenance work). For spare parts with reserved quantity, the demand date needs to be combined with the current inventory quantity and the correct order quantity And inventory parameter setting, for some spare parts purchase application demand date without reserved quantity, factors such as frequency of use, importance of spare parts and other factors need to be considered in setting.

[0047]Although there is no need for on-site maintenance work in the purchase application for unreserved spare parts, failures may still occur and replacements may occur. At the same time, spare parts with high frequency of use and spare parts with low frequency of use, and spare parts with high importance and low importance have different priorities. For spare parts with high freq...

Abstract

The invention relates to a nuclear power station spare part purchasing demand date optimization method and a computer. The method comprises the steps: automatically obtaining and calculating historical supply data of spare part suppliers corresponding to spare part names, obtaining the actual reliability of the spare part suppliers according to the historical supply data, wherein the actual reliability is the ratio of the on-time on-time supply order number to the total order number; judging whether the actual reliability is greater than or equal to preset reliability; if not, gradually increasing the supply time of each order in the historical supply data according to the preset step length, and synchronously calculating the actual reliability of the backup part supplier when the supply time is increased each time until the actual reliability is greater than or equal to the preset reliability, wherein the increased supply time is the correction time at the moment; and correcting the demand date in the purchase order data by using the correction time. Optimization of the nuclear power station spare part purchasing demand date is achieved by analyzing the historical supply data so that the more accurate demand date can be provided for the nuclear power station spare parts and the management efficiency can be enhanced.
