At present, with the increase of the operation of nuclear power plants, the intensive effect of cluster plants is more obvious, taking the quantity of spare parts to be reserved as an example, the availability probability of certain important spare parts is very low, if a single power plant is reserved, each power plant needs to reserve one stock, and if three power plants use the spare parts, one stock is reserved totally. The current MRP module can only operate with a single power plant, can not realize the condition of combined operation of multiple power plants, can only trigger purchase application by a certain power plant, and then initiates a spare part allocation flow to other power plants through manual review, and the efficiency is lower.

Example 4
Referring to fig. 4, in this embodiment, according to the actual situation of each nuclear power plant, the MRP operation mode of the multiple power plants is divided into an "entity joint storage power plant mode" and a "virtual joint storage power plant mode", where the entity joint storage power plant mode means that a spare part is shared by two or more power plants, and all the power plants shared originally have set inventory parameters, and perform autonomous purchasing and storage. The virtual combined storage power plant mode means that a certain spare part is shared by two or more power plants, all the power plants shared originally are provided with inventory parameters, independent purchasing and storage are carried out, after virtual combined storage, a group plant establishes a group plant virtual power plant for setting the inventory parameters, the virtual power plants aggregate the inventory, reservation and forward order of the group plant, the total quantity to be purchased is determined, distribution is carried out in each power plant, the power plants shared originally are provided and reserved with a certain quantity of safety inventory as required, and the maintenance requirement that the fault repair time of the part on site is shorter than the allocation time of the spare part group plant is met.
The entity allies oneself with the condition that stores up power plant mode is mainly used for the distance between the power plant is close, can accept large-scale cross power plant material receiving, is applicable to a plurality of units in the same nuclear power base because owner's share right reason usually, manages according to different nuclear power plants. The virtual cogeneration plant model is applicable to all nuclear power plants that use the same spare parts. The physical combined storage power plant mode can be used together with the virtual combined storage power plant mode. The operation methods of the physical cogeneration plant mode and the virtual cogeneration plant mode are explained further below.
4.1 method of operation in physical combined storage power plant mode.
The MRP parameter setting, purchasing and storing of spare parts of multiple power plants are integrated into a single power plant for management through a mode of running an entity combined storage power plant. Taking fig. 4 as an example, a certain spare part a is used in all of the nuclear power plant 1010, the nuclear power plant 1020 and the nuclear power plant 1030, and is stored in a united manner by the entity united storage power plant 2010, and is assigned to a fixed power plant (the nuclear power plant 1010 in the example of fig. 4) to be purchased and stored after a triggered purchase application, and when the nuclear power plant 1020 and the nuclear power plant 1030 need the spare part, the spare part a is taken from the nuclear power plant 1010 in a cross-power-plant material receiving manner.
And under the entity combined storage power plant mode, the combined storage MRP operation module determines the quantity to be purchased according to the spare part MRP parameter in the MRP parameter setting module by reading the summarized spare part inventory, reservation and forward order data, and outputs the quantity to the combined storage power plant determined by the spare part for purchase. In the embodiment, a factory code is established, for example, "2010", the factory of the code is regarded as an independent power plant, the related data of each original power plant is collected through the data collecting module, the MRP operation module can directly use the MRP module which is mature on the market currently, the MRP operation module reads the data in the collecting module, the purchase quantity of the spare parts is determined according to the MRP parameters of the spare parts in the MRP parameter setting module, and the purchase application distribution module determines the power plant for developing the purchase of the spare parts by reading the information of the combined storage power plant in the MRP parameter setting module. In the implementation process, the main difficulty is information supplement in the entity joint storage spare part MRP parameter setting module, including MRP inventory parameter setting of each spare part and allocation of purchased and stored power plants during joint storage of each power plant. It needs to achieve the following 3 goals:
1) the condition of spare parts used across the power plant is minimized, namely, the extra cost caused by the material receiving across the power plant is reduced;
2) after the entity power plant is stored in a united manner, the MRP triggering purchase amount is less than the sum of the MRP triggering purchase amounts before the power plants are stored in a united manner, namely the total stock required to be purchased and stored after the united storage is carried out is reduced;
3) the proportion of each power plant (MRP triggered purchase amount after combined storage/MRP triggered purchase amount before combined storage) is close, namely the income proportion of each power plant after combined storage is close.
Referring to fig. 5, how to calculate MRP inventory parameters of spare parts and allocate power plants for purchase and storage during combined storage is further explained below, and S401 is to recalculate MRP parameters of spare parts after integrating the procurement data of each power plant according to historical procurement data of spare parts in multiple power plants, so as to ensure that the sum of MRP trigger purchase amount after combined storage of entity power plants is less than the sum of MRP trigger purchase amount before combined storage of each power plant. And determining the calculated MRP parameter of the spare part as the MRP parameter of the entity combined storage power plant. The inventory parameter setting principle of the high-turnover spare parts is as follows: the re-ordering point is the receiving quantity in the purchasing period plus the safety stock, and the receiving quantity of economic ordering batches or one year is selected in the ordering batches; the inventory parameter setting principle of the non-high turnover spare parts is to set a certain amount of safety inventory by combining the future probability of receiving and the management requirement of the cargo availability. As long as the stock parameter setting principle is consistent before and after combined storage, the MRP triggered purchase amount after combined storage is less than the sum of the MRP triggered purchase amounts before combined storage of each power plant. For example, according to the historical availability records of spare parts, the reordering points of the nuclear power plant 1010, the nuclear power plant 1020 and the nuclear power plant 1030 are respectively 1.4, 0.7 and 0.8, and the stock parameters are basically set to be integers, so that the reordering points of the three nuclear power plants are respectively set to be 2, 1 and 1, and the sum of the reordering points is 4. After the combined storage, the calculation value of the re-ordering point is 2.9(1.4+0.7+0.8), the setting value of the re-ordering point is 3, and the MRP triggering purchase amount after the combined storage is less than the sum of the MRP triggering purchase amounts before the combined storage of each power plant. S402, selecting the power plant with the highest historical utilization number as the combined storage power plant according to the historical utilization number of the spare parts in the last 5 years, and reducing the condition that the spare parts are utilized across the power plants if the utilization numbers are different. And S403, calculating the MRP triggered purchase amount before combined storage of each power plant and the MRP triggered purchase amount after combined storage of each power plant. S404, aiming at spare parts with the same number in the last 5 years, selecting a power plant with a small numerical value of 'MRP triggered purchase amount after combined storage/MRP triggered purchase amount before combined storage' as a combined storage power plant, so that the gains obtained by all the power plants participating in the combined storage are close. S405, if the numerical values of 'MRP triggered purchase amount after combined storage/MRP triggered purchase amount before combined storage' of each power plant in combined storage are still obviously different (after initialization setting is finished), selecting part of spare parts with high value, and taking the power plant with small numerical value of 'MRP triggered purchase amount after combined storage/MRP triggered purchase amount before combined storage' as the combined storage power plant of the spare parts. When each power plant develops the physical combined storage power plant mode, the method for initializing allocation of spare parts of each power plant is used for calculating the MRP inventory parameters of the spare parts and allocating procurement and storage power plants, and for the follow-up newly-added common code spare parts, after the newly-added common code spare parts are summarized according to the month degree, the MRP inventory parameters of the spare parts and allocating procurement and storage power plants are calculated according to the method (without S405) of FIG. 5.
4.2 virtual combined storage power plant mode operation method
Through the mode of operating the virtual combined storage power plants, the MRP operation of a plurality of power plants is normalized to a virtual factory, the purchase application is triggered, and then the purchase application is distributed to each power plant for purchase. The combined storage MRP operation module under the triggering purchase application mode determines the quantity to be purchased according to the spare part MRP parameters in the MRP parameter setting module by reading the summarized spare part inventory, reservation and forward order data, and outputs the quantity to the combined storage power plant determined by the spare part for purchase. The example can adopt a factory code, such as '3010', as an independent power plant, summarize the related data of the original power plants through a data summarization module, the MRP operation module can directly use the current commercially mature MRP module, read the data in the summarization module, determine the purchase quantity of the spare parts according to the MRP parameters of the spare parts in the MRP parameter setting module, and the purchase application distribution module distributes the purchase application of the spare parts to each power plant by reading the historical pick-up distribution list and the safety stock reserve list in the MRP parameter setting module and combining the stock, reservation and forward order information of the spare parts in each power plant. In the implementation process, the main difficulty is information supplement in a spare part MRP parameter setting module and operation of a purchase application distribution module, wherein the spare part MRP parameter setting module comprises parameters of MRP inventory parameter setting, a historical pick-up distribution list, a safety inventory reserve list and the like of each spare part, and the purchase application distribution module comprises power plant combined storage contribution degree data. The development of virtual joint storage needs to achieve the following 3 goals:
1) the condition of spare parts used across the power plant is minimized, namely, the extra cost caused by the material receiving across the power plant is reduced;
2) the MRP triggering purchase amount after virtual power plant combined storage is less than the sum of the MRP triggering purchase amounts before each power plant combined storage; the total stock required to be purchased and stored is reduced after the joint storage is carried out;
3) the contribution degree of the combined storage of each power plant (the amount of the transferred power plant-the amount of the transferred power plant)/the amount of the combined storage of the power plants is close, namely the income obtaining proportion of each power plant after the combined storage is carried out is close.
With reference to fig. 6, how to calculate the virtual joint reserve MRP parameter setting module parameters is further explained below. S601 is that according to historical utilization data of spare parts in multiple power plants, the MRP parameters of the spare parts are recalculated, and the fact that the MRP triggering purchase amount of the virtual combined storage power plant is smaller than the sum of the MRP triggering purchase amounts before combined storage of all the power plants is ensured. And determining the calculated MRP parameter of the spare part as the MRP parameter of the virtual combined storage power plant of the spare part. S602, aiming at part of important spare parts, each power plant sets a certain amount of safety stock according to needs, and a spare part safety stock reserve list is established. The safety stock of each power plant does not participate in the inter-plant combined storage and allocation in principle. S603 is that according to historical availability data of spare parts in each power plant, the historical availability quantity proportion of the spare parts is determined, such as n1: n2: n3, a distribution list of historical availability of the spare parts is established, and the distribution list is updated regularly.
Referring to fig. 7, since the virtual combined storage power plant mode uniformly triggers a purchase application through the MRP parameters of the spare part group plant, the purchase application is distributed among the nuclear power plants through the purchase application distribution module. In the virtual joint storage spare part purchase application distribution module purchase application distribution method, S701 is to call a spare part safety stock inventory and supplement the difference value between the stock supplemented with actual stock and the safety stock set value of each power plant; s702, calling reserved, stocked and positively ordered data of each power plant, supplementing the difference value between the reserved and stocked + positively ordered data of each power plant, if the difference value of a certain power plant is greater than the purchase quantity triggered by demand combined storage, indicating that other power plants store/purchase redundant spare parts, and synchronously transferring the spare parts stored/purchased by other power plants to the power plant; s703, calling a historical procurement distribution list of spare parts, distributing the quantity to be purchased according to the historical procurement quantity proportion of the spare parts in each power plant, and only taking integers, for example, the quantity calculated by a certain power plant according to the historical procurement is 3.6, and only 3 are purchased at this stage; and S704, distributing the residual quantity to be purchased according to the joint storage sharing contribution degree of each power plant, for example, purchasing the power plant distributed to the lowest (transfer amount-transfer amount)/median value of the joint storage inventory of the power plants, thereby balancing the joint storage income of each power plant. The operation principle is further illustrated below, assuming that 3 nuclear power plants (a, b, and c, respectively) perform virtual combined storage, the safety stock to be stored in each plant is 1, the historical receiving quantity ratio is 2:1:1, no stock and a positive order are available at present, 2 reservations are available, the shared degree of combined storage of the nuclear power plant a is the lowest, and a purchase application triggered by a group plant is to purchase 20 spare parts. After S701, each power plant purchases 1 safety stock, and the rest 17 purchase applications of the group plants are to be distributed; after S702, each power plant purchases 2 spare parts through reservation and inventory + positive order calculation, the reservation requirement is met, and the rest 11 purchase applications of the group plants are to be distributed; after S703, respectively allocating 5, 2 and 2 purchases according to the historical utilization proportion of the power plant, and remaining 2 purchase applications of the group plant to be allocated; after step S704, the remaining 2 spare parts are purchased by the nuclear power plant a according to the joint storage sharing degree of the cluster plant. That is, 20 purchase applications are triggered by the group plants, and after entering the purchase application distribution module, 10, 5 and 5 are purchased by each power plant respectively.
