Description

Technical Field

[0001] This invention relates to the field of enterprise resource planning technology, and in particular to a material management method and system based on intelligent balancing inventory. Background Technology

[0002] In large enterprise groups, especially in industries such as power and engineering, materials management typically requires managing both engineering projects and spare parts projects simultaneously. However, the materials management functions of traditional ERP systems have significant limitations:

[0003] First, inventory coordination is inefficient. Traditional "balanced inventory" is usually limited to a single project and cannot be used for global inventory allocation across projects (such as from spare parts projects to engineering projects). Cross-project coordination relies on cumbersome manual operations, resulting in inefficient use of inventory resources.

[0004] Secondly, business and financial data are prone to disconnect. After the status of materials changes, financial accounting often relies on manual entry, which is not only inefficient but also prone to inconsistencies between business and financial data, leading to data distortion and decision-making risks.

[0005] Finally, there is a lack of effective cost control. The procurement and requisition of spare parts and components lack prior technical constraints and rely heavily on post-event approvals, resulting in lagging management and difficulty in effectively controlling the rise in inventory costs.

[0006] Therefore, there is an urgent need for a technical solution that can achieve automatic inventory coordination, real-time business and financial linkage, and hard risk control to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a material management method and system based on intelligent balancing inventory, in order to solve the above-mentioned technical problems.

[0008] The present invention provides a material management method and system based on intelligent balancing inventory, which adopts the following technical solution: To determine the material requirements of the target project, obtain a list of material requirements for the target project. Perform a cross-project balance inventory calculation, extending the scope of the inventory calculation to the inventory of at least one spare parts item associated with the target project, and generate inventory results; If the inventory results indicate that the material requirements of the target project need to be transferred from the inventory of at least one spare parts project, a project material conversion order is generated, and other corresponding outbound orders and other inbound orders are generated in conjunction with the project material conversion order. If the results of the inventory check indicate that there is still a shortage of materials, a purchase requisition will be generated. When creating a purchase order for the aforementioned spare parts project, the execution of the purchase order is controlled according to the pre-configured inventory amount limit rules.

[0009] Secondly, a materials management system based on intelligent balancing inventory includes: The list acquisition module is configured to acquire the material requirements list of the target project in response to the material requirements of the target project. The inventory balance calculation module is configured to perform cross-project inventory balance calculation, which extends the scope of the inventory balance calculation to the inventory of at least one spare parts item associated with the target project, and generates inventory balance results. The conversion processing module is configured to automatically generate a project material conversion order if the inventory results indicate that a transfer from the spare parts inventory is required, and to generate other corresponding outbound orders and other inbound orders based on the project material conversion order. The purchase requisition generation module is configured to generate a purchase requisition if the inventory results indicate that there is still a shortage of materials. The procurement control module is configured to control the execution of the procurement order based on a pre-configured upper limit rule for inventory amount when a procurement order for the spare parts item is created. The rule configuration module is configured to set the upper limit rule for inventory amount and the over-limit handling strategy for spare parts and components projects, and to persistently store the rules in a rule configuration table; The outbound interception module is configured to automatically verify and intercept the direct material requisition and outbound instruction for spare parts projects when it receives such an instruction, and force the outbound process to be carried out through the project material conversion process.

[0010] Thirdly, an electronic device is provided, comprising: at least one processor, and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the steps of the material management method based on intelligent balance stock of any embodiment of the present invention.

[0011] Fourthly, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein when the program instructions are executed by a processor, the processor performs the steps of the material management method based on intelligent balancing inventory according to any embodiment of the present invention.

[0012] The beneficial effects of the material management method based on intelligent balancing inventory provided by this invention are as follows: 1. Improve inventory utilization and collaboration efficiency: Through cross-project intelligent inventory calculation, inventory information silos are broken down, and automatic optimization of inventory resources at the enterprise level is achieved, reducing procurement costs and capital occupation.

[0013] 2. Ensure real-time consistency of business and financial data: By automatically triggering the association of inbound and outbound documents and financial vouchers through conversion orders, an automated closed loop of business and finance is formed, which completely eliminates errors caused by manual intervention and ensures the accuracy and synchronization of data.

[0014] 3. Strengthen risk management capabilities: By strictly controlling the total inventory amount and intercepting outbound compliance, management rules are transformed into technical means for mandatory system execution, thus achieving effective pre- and in-process control of operational risks.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, but does not exclude other elements or objects.

[0017] Please see Figure 1 The diagram shows a flowchart of a material management method based on intelligent balancing inventory according to this application.

[0018] Step S1: Obtain the material requirements list for the target project based on its material requirements. In this step, the user initiates a material requirements plan (MRP) for a specific project within the CYERP system or manually creates a material requirements list. The system retrieves this list as input for subsequent inventory calculations.

[0019] Specifically, before executing step S1, the method also includes step S0, which configures the inventory amount limit rules and over-limit handling strategies for the spare parts project, and persistently stores the rules in a rule configuration table; the over-limit handling strategies include prohibiting procurement, issuing warnings, or adjusting proportionally.

[0020] Specifically, the configuration of the upper limit rules for inventory amount includes: supporting configuration on an annual cycle and providing a one-click reference function to copy the list of spare parts and components and rule configurations of the previous year to generate the initial configuration of the current year; the spare parts and components items are divided and maintained according to the responsible departments of the organization.

[0021] This step is a prerequisite for performing inventory calculation. The system administrator creates or designates a "Spare Parts Item" for centralized storage of general spare parts through the system's rule configuration interface. Inventory amount limits are configured for this type of item; for example, an annual inventory limit of 1 million yuan can be set for a department's spare parts item. Simultaneously, over-limit handling strategies are set, such as "prohibit procurement," "early warning," or "proportional adjustment." To improve efficiency, the system provides a "one-click reference" function, automatically copying the previous year's spare parts item list and its rule configuration to the current year, allowing administrators to make adjustments. These rules are persistently stored in the database's rule configuration table, with relevant fields including item ID, amount limit, and over-limit strategy.

[0022] Step S2: Perform cross-project inventory balancing calculation, extending the scope of the inventory balancing calculation to the inventory of at least one spare parts item associated with the target project, and generate inventory balancing results; Specifically, performing cross-project balanced leverage calculations includes: The current inventory information of the target project is obtained through a microservice, and the inventory information of related spare parts projects is obtained by performing a database joint query. For each material in the material requirement list, calculate its total available quantity in the current project inventory and spare parts project inventory, and allocate it using a priority algorithm; Generate a structured inventory utilization result, which clearly lists: the details of materials that can be satisfied from the current project inventory, the details and sources of materials that need to be transferred from the spare parts project, and the list of materials that still need to be purchased.

[0023] In this step, the system invokes a separate microservice to handle the request. This microservice performs the following sub-steps: The current inventory information of the target project itself can be obtained by querying through the internal API.

[0024] By performing a joint database query, and based on the relationships such as the responsible departments of the organization, the inventory information of all related spare parts and components items is obtained, forming a global "extended resource pool".

[0025] For each material in the demand list, calculate its total available quantity in the target project inventory and the spare parts project inventory.

[0026] The allocation is calculated using a priority algorithm: priority is given to allocating from the target project's own inventory, and any shortfall is then allocated from the spare parts project's inventory.

[0027] The final result is a structured Likud result. This result is not simply a matter of whether the condition is met, but rather it explicitly lists three categories of details: 1. The materials and quantities can be directly supplied from the project's inventory; 2. A list of materials that need to be transferred from the spare parts and components project, including their quantities and specific sources (which spare parts and components project). 3. The bill of materials still needs to be fulfilled through procurement.

[0028] Step S3: If the inventory results indicate that the material requirements of the target project need to be transferred from the inventory of at least one spare parts project, a project material conversion order is generated, and other corresponding outbound orders and other inbound orders are generated in conjunction with the project material conversion order. Specifically, the step of generating corresponding outbound and inbound orders based on the project material conversion order includes: In response to the approval of the project material conversion order, the document generation action is automatically triggered; Based on the transfer-out project information in the project material conversion form, an additional outbound order with the outbound type identified as spare parts transfer-out will be automatically generated. Based on the transfer-in project information in the project material conversion form, an additional inbound form with an inbound type identifier of project material transfer will be automatically generated. Among them, the other outbound orders and the other inbound orders are logically associated with the project material conversion order; In response to the posting operations of the other outbound and inbound orders, financial vouchers recording changes in inventory accounts are automatically generated and transmitted to the financial accounting module.

[0029] In this step, if the inventory results indicate that a transfer from the spare parts project is required, the system will automatically generate a "Project Material Transfer Order". This order records information such as the transferor (spare parts project), the transferee (target project), material details, and quantity, and then enters the preset approval process.

[0030] In response to the approval event of the conversion form, the system automatically triggers subsequent associated processing through the built-in workflow engine: According to the "transfer out" information in the conversion form, an "other outbound order" is automatically generated, and its outbound type is automatically marked by the system as "transfer out of spare parts and components". After this document is posted, the inventory ledger of the spare parts and components item is correspondingly reduced.

[0031] Synchronously, according to the "transfer in" information in the conversion form, an "other inbound order" is automatically generated, and its inbound type is marked as "transfer in of project materials". After this document is posted, the inventory ledger of the target engineering project is correspondingly increased.

[0032] These two inbound and outbound orders are associated with the project material conversion form in terms of business logic, ensuring the traceability of the business process.

[0033] Furthermore, in response to the posting operations of these two documents, the CYERP system automatically triggers the financial voucher generation rule through its interface integrated with the financial intelligent sharing platform, generates an accounting voucher recording an increase and a decrease in the "inventory" account, and transmits it to the financial system, achieving real-time and automatic synchronization of business operations and financial accounting, and completely eliminating errors and lags that may be caused by manual entry.

[0034] Step S4, if the inventory utilization result indicates that there is still a shortage of materials, a purchase requisition is generated; In this step, if the inventory utilization result still indicates a shortage of some materials, the system automatically generates a purchase requisition according to the list of materials still to be purchased and enters the subsequent procurement process.

[0035] Step S5, when creating a purchase order for the spare parts and components item, control the execution of the purchase order according to the pre-configured inventory amount upper limit rule.

[0036] Specifically, controlling the execution of the purchase order includes: When saving or submitting the purchase order, trigger the real-time verification logic; Calculate the estimated total inventory of the spare parts and components item corresponding to this order and compare it with the amount upper limit stored in the rule configuration table; If it is expected to exceed the limit, perform operations according to the over-limit handling strategy: if the strategy is "prohibit procurement", prevent the order from being created; if the strategy is "warning prompt", pop up a warning box; if the strategy is "adjust by proportion", prompt the user to adjust according to the calculated procurement upper limit.

[0037] In this step, when a purchasing staff member creates a purchase order for spare parts, the system triggers a real-time verification logic. This logic queries the current total inventory of the spare parts item and adds it to the amount of this purchase order to calculate the estimated total inventory. Subsequently, the system accesses the rule configuration table and compares the estimated total with the preset upper limit. If the estimated limit is exceeded, hard control is executed according to the preset "over-limit handling strategy": if the strategy is "prohibit purchasing," the system directly throws a business exception and prevents the order from being saved; if it is "warning prompt," a warning box pops up to remind the purchasing staff, but allows them to choose to force submission; if it is "adjust proportionally," the system automatically calculates and prompts the current maximum purchaseable amount, guiding the user to adjust.

[0038] In particular, the method of the present invention further includes step S6, which automatically verifies the project attributes of the outbound target when a direct material requisition and outbound instruction for a spare parts project is received; if the outbound target is a spare parts project, the outbound process is interrupted and the outbound process is forcibly required to be carried out through the project material conversion process.

[0039] In this step, to prevent human error, the system automatically verifies the outbound target when it receives any "direct material requisition" instruction for spare parts projects. If the outbound target is still "spare parts project," the outbound process is immediately interrupted, and the system displays the message: "Skirt parts are prohibited from direct requisition; please allocate them through the 'Project Material Conversion' process!" This technical measure enforces that all spare parts must undergo a standardized conversion process before use, ensuring the accuracy of cost allocation.
