[0098] The project management subsystem 6 is used to conduct project progress survey, experimental process data survey and project change approval of the target project based on the project library.

[0099] The working principle and beneficial effects of the above technical solution are:

[0100] When conducting full life cycle management of scientific research projects and materials, the scientific research institution team creates a project list for the entire scientific research institution (including project team, project history and stage report, etc.), generates a project library after approval, and then builds a material library based on the local material information in the inventory library.

[0101] After having the two most important basic libraries, the project library and the material library, as the work begins, the material purchase application used in the project research process is submitted at the beginning of each month. After the first integration by the material clerk, the heads of each research group will review and approve it, and then the materials will be summarized to the material purchaser of the entire research institution for secondary integration and confirmation. After confirmation, the purchase details will be automatically generated for purchase. After the supplier is determined, each supplier will submit the supply details, and then the material manager will directly import the supply details into the system to generate an acceptance order. After the entry is confirmed, the goods will be automatically shipped out to each research group or later on, the material manager of the entire research institution will ship out the goods for the second time. After shipping out, the system automatically summarizes the budget of each research group this month and the actual purchase expenses, automatically calculates the tax-free price and tax-inclusive price, and hands it over to the financial department for account verification and payment management.

[0102] After completing the procurement, scientific researchers can select the equipment and material information used to conduct scientific research experiments during the experiment, record the experimental data and results online in real time during the experiment, submit a stage summary report at a certain stage, and finally submit a project acceptance report; if the experimental arrangement needs to be adjusted according to the experimental records during the project management process, and the project members need to be adjusted according to the team management needs, the project change approval can be initiated at any time. After approval, the original experimental records and procurement applications will not be affected; the experimental process data and project progress occurring at each stage can be investigated at any time during the project management process.

[0103] The present invention integrates the purchase, procurement, acceptance and automatic calculation of cost information for materials submitted at different stages. At the same time, it automatically conducts project progress survey, experimental process data survey and project change approval for the target project, thus realizing overall project management and material budget management throughout the project life cycle. The management synergy effect is enhanced and the efficiency of scientific research project management is further improved.

[0104] In one embodiment, the inspection and receipt order generation subsystem connects with the target supplier based on the purchase details and obtains the supply details of the target supplier, including:

[0107] Based on the target screening conditions, select target suppliers according to the procurement project sets that the pre-selected suppliers can complete;

[0108] Among them, the target screening conditions include:

[0109] When there is no specific procurement project in the procurement project set of the target supplier, the number of procurement projects in the procurement project set is greater than or equal to a preset first threshold; wherein the specific procurement project is: a project that can only be completed by the target supplier; the preset first threshold is manually preset, for example: 2;

[0110] When there are specific procurement items in the procurement item set of the target supplier, the number of procurement items in the procurement item set is greater than or equal to a preset second threshold; wherein the preset second threshold is manually preset, for example: 1;

[0111] There is no overlap in the procurement items among the target suppliers;

[0112] The target supplier has a history of credible cooperation with the local, and / or the target supplier's supply credit score is greater than or equal to a preset score threshold; where historical credible cooperation means: the target supplier and the local scientific research unit have a cooperation recognized by the local scientific research unit; the supply credit score means: the score given to the target supplier by the target supplier information provision platform; the preset score threshold is manually preset, for example: 90;

[0113] The total number of target suppliers is less than or equal to a preset third threshold value, wherein the preset third threshold value is manually preset, for example, 5.

[0114] The working principle and beneficial effects of the above technical solution are:

[0115] The present invention splits the procurement details, determines multiple procurement items, connects with pre-selected suppliers, collects the procurement items that each pre-selected supplier can independently complete, introduces target screening conditions, and screens target suppliers; the target screening conditions specifically include:

[0116] Condition 1: When a procurement project can only be completed by a specific supplier, the number of procurement projects is constrained to be greater than or equal to the first threshold (for example: 1);

[0117] Condition 2: When a supplier cannot complete a specific procurement item, the number of its procurement items is preset to be greater than or equal to a second threshold (e.g., 2);

[0118] wherein the first threshold is less than the second threshold;

[0119] Condition 3: There is no overlap in the procurement project sets between target suppliers, which improves the utilization rate of supply resources;

[0120] Condition 4: The total number of target suppliers is less than or equal to the third threshold. While completing the procurement tasks corresponding to the procurement details, the number of target suppliers to be connected is restricted to improve the connection efficiency.

[0121] The present invention introduces multiple target screening conditions to screen target suppliers, and the selection of target suppliers is more reasonable.
