Technical Field

[0001] This invention relates to the field of digital procurement technology, specifically to a multi-role collaborative bidding and procurement lifecycle management system. Background Technology

[0002] Traditional electronic bidding systems on the market have problems such as procurement application, planning, announcement, bid opening and evaluation, and contract performance being separate modules with no data sharing. This requires manual copying of data across systems, reliance on manual risk control, potential for oversights, difficulty in tracing the bidding process, and difficulty in assigning responsibility.

[0003] The existing bidding management system has the following shortcomings: Existing technology CN106886862A discloses a bidding and procurement management system and method, which includes a system management module, a storage module, an application module, and a data interface module. The system management module, application module, and data interface module are all connected to the storage module. The application module includes a project management module, a scoring management module, an expert management module, a document management module, an audit management module, and a query module. This invention also discloses a bidding and procurement management method, including the generation and publication of bidding documents, the uploading and saving of bidders' basic information, project scoring, automatic generation of evaluation results and winning bid announcements, and contract archiving. This invention uses information technology for the unified management and classification of bidding data. Through the integration of information resources, it simplifies processes, reduces errors, improves efficiency, and facilitates flexible access and retrieval by relevant personnel.

[0004] The aforementioned technologies do not address reducing the workload of manual intervention, are difficult to handle large amounts of data, and manual data processing carries a high error rate. Therefore, a highly automated, multi-party collaborative, and low-risk multi-role collaborative bidding and procurement lifecycle management system is needed to solve this problem. Summary of the Invention

[0005] One objective of this application is to provide a multi-role collaborative bidding and procurement lifecycle management system that can solve the technical problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-role collaborative bidding and procurement full lifecycle management system, including a bidding and procurement pre-stage module, a bidding and procurement execution stage module, a bidding and procurement performance stage module, and a public basic support module.

[0007] Preferably, the procurement application submodule is used for multiple departments of the procuring entity to submit procurement application forms online. The procurement application submodule has a built-in AI intelligent judgment engine to automatically identify whether the procurement project meets the "three major and one important" control rules and automatically mark risk items. The procurement coordination submodule is used for unified coordination of procurement application forms, automatically splitting and merging to generate standardized procurement packages, and visually configuring the procurement fund budget items, budget amount and package total price association binding. The procurement coordination submodule uses an AI market research intelligent agent to capture historical procurement data, intelligently analyze mainstream market brands, historical quotations and parameter benchmarking data, and output market analysis reports.

[0008] Preferably, the procurement plan application submodule is used for online visual creation of procurement plan documents. It has built-in intelligent inquiry, online questionnaire, and third-party commissioned survey channel demand collection tools. At the same time, it automatically verifies the completeness of procurement plan fields, budget compliance, and project classification specifications through an AI preliminary review agent, and then outputs preliminary review opinions. The project management submodule uses the project transfer scheduling engine to transfer projects to agencies and procurement centers with one click. After the transfer, the operation account permissions are automatically switched, and the purchaser can independently create projects. Documents are automatically pushed to multi-level approval workflows. The procurement document preparation submodule includes online intelligent preparation, offline preparation, AI intelligent review agent, and online editing of the bid opening summary table. It supports one-click copying and batch reuse of tables. The online intelligent preparation has a built-in standardized procurement document template library for quick fill-in-the-blank preparation.

The procurement agent end is used to view the entire bid evaluation process in real time, with data synchronized in real time. The bid award notice management submodule is divided into a purchaser end, an agency end and a supplier end. The purchaser end is used for uploading and viewing the notice online and registering service fees offline. The agency end is used for uploading and archiving online and confirming service fee receipt online. The supplier end is used for online electronic signing of the bid award notice.

[0013] Preferably, the contract management submodule automatically verifies the compliance risks of the uploaded contract draft through a contract review intelligent agent. After the final draft is uploaded, it is automatically synchronized to the corresponding winning supplier account. The supplier clicks to confirm the contract online, uploads the stamped scanned copy for filing, and automatically jumps to the performance acceptance process after the filing is completed. The performance acceptance submodule completes the online filing and archiving of acceptance by uploading signed acceptance documents online.

[0014] Preferably, the approval center is a multi-level sequential approval process that proceeds step by step from the functional supervisor, the planning and finance department, the supervisor in charge, and the procurement center. The approval data is synchronized with the procurement plan page in real time, and the entire process is traceable. The workbench is a unified portal that aggregates information such as enterprise certification status, announcements of pending registration, and quick access to projects pending bidding.

[0015] Preferably, the user center is used for unified account permission management, including maintaining the accounts, roles and operation permissions of purchasers and internal personnel of agencies. The rule base configuration center allows for online addition, deletion, modification and query of project number generation rules and "major issues" judgment rules through visual custom configuration, which takes effect globally in the system.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves a closed-loop digital process for the entire procurement process, with automated data flow between the front and back ends, eliminating the need for repetitive manual data entry and reducing the workload of human labor. At the same time, through AI-enabled intelligent capabilities, the preparation of various procurement documents and compliance reviews are highly efficient and have a low error rate. Furthermore, the degree of automation in compliance risk control is high. The "major issues" and compliance judgments in the procurement process do not rely on manual labor, thus reducing the risk of corruption and improving the reliability and security of data flow.

[0017] 2. This invention enhances the online collaboration capabilities of purchasers, agents, experts, and suppliers, making project handover and review processes more efficient online. It reduces the number of announcement channels and automates the archiving process, with screenshots, links, and online posting times automatically registered via AI, significantly saving communication time among all parties.

[0018] 3. This invention lacks intelligent analysis tools for procurement budgets and market conditions, lacks data support for procurement planning, has a low degree of online contract and performance acceptance, relies on offline transfer of filing materials, makes traceability difficult, lacks a unified rule configuration center, and cannot visualize and customize project numbers and risk control rules.
