Description
Technical Field
The invention relates to the technical field of bidding, in particular to an online trading platform based on a block chain.
Background
At present, bidding is a comprehensive economic responsibility system form for promoting competition in the field of basic construction, with the rapid development of the Internet, the bidding activities are gradually electronized, the electronic bidding enables the communication process to be more convenient, and the efficiency of the whole bidding work is obviously improved on the premise of reducing the cost. The bidding process of the existing electronic bidding platform mainly comprises the following steps: the tenderer needs to register and log in the electronic tendering and bidding platform to input basic information for auditing. And after obtaining the bidding qualification, the tenderer registers the bidding project, can begin to compile bidding documents, can upload the bidding documents after completing the compilation, and releases the bidding information on the bidding platform. The same bidding enterprises want to participate in the bidding process, and need to register and log in the bidding platform and submit the enterprise information for auditing; after obtaining the bidding qualification, the bidding enterprise can search the interested items by checking the bidding announcement in the bidding platform and download the bidding document, and can generate the bidding document on line and realize on-line one-key remote bidding. After the bid is opened, the bid inviting unit invites the bid evaluation experts to evaluate the bid on the project. The expert can develop bid evaluation work after logging in the platform, the project can be scored according to the grading detailed rules appointed by the bid inviting party in the bid evaluation process, whether the bid inviting party has bad bidding behaviors including false bidding and the like or not in the bidding link is evaluated, after all bid evaluators complete the work of the expert, bid evaluation results can be uniformly submitted to bidding units for accurate calculation according to the grading detailed rules and the bidding information of suppliers, one or more bid winning units are selected from the first few bidding units in the ranking, and finally bid winning announcements are issued.
Although the existing electronic bidding platform can realize electronic bidding, the following problems exist: firstly, the management workload of suppliers is large, and the efficiency is low: since the existing supplier qualification information is directly provided by the supplier, the possibility of counterfeiting the supplier information exists, which may result in the network being marked in a poor supplier. In the bid evaluation process, an evaluation expert needs to verify a series of paper support materials provided by a supplier item by item, each batch of items need to be verified, cross-batch information is difficult to share, verification workload is large, data among different network provinces cannot be shared, and difficulty in manually identifying false bid information is high. Secondly, the bidding process is complex, and consumes time and labor: for each bid inviting project, a supplier needs to go through a series of processes of purchasing bid documents, making the bid documents, signing and sealing, bidding on site, waiting for bid opening and the like, a large amount of manpower and material resources are consumed, and the quality of the bid documents is difficult to ensure. In the bid document making process, the basic information of the suppliers of different projects needs to be repeatedly filled, so that the time of the suppliers is wasted, and the workload of experts is increased; and each project needs to make an optical/U disk of the bid document. In the delivery process of the bidding documents, a supplier needs to go to a bidding hall before bidding opening, so that the bidding site is easy to be disordered, and a large number of workers are needed to maintain the site order; the staff is faced with a great deal of manual work such as classifying, carrying, splitting the bid documents. If remote bid evaluation is needed, remote carrying work of the bid document optical disc/U disc is involved, which not only consumes manpower, but also can cause damage to the bid document. The evaluation criteria are strong in subjectivity and different: the existing bid evaluation process mostly depends on experience, knowledge architecture, technical level and the like of evaluation experts, and the problems of large individual difference and strong subjectivity are easy to occur. Moreover, the current bid evaluation result is mainly based on the on-site bid evaluation score of an expert, neglects the assessment of the daily performance of the supplier, such as the past service quality of the supplier, and is not beneficial to forming a good cycle of supplier management for quality inspection. Finally, there is some hysteresis in the supply chain management of supplies: after the bidding is completed, the bidding enterprise and the tenderer need to sign a contract, during actual operation, after the bidding purchase is completed, the tenderer and the bidding enterprise generally need to complete the contract signing within the appointed number of days, a certain time difference exists between the issuance of the bid-winning notice book and the contract signing, and a certain hysteresis exists in the management of the material supply chain. Fifthly, in the bidding evaluation link, risk early warning to the suppliers is lacked: the past performance behaviors of suppliers are considered only in a business scoring link as one of grading items, the evaluation of information such as performance capability, product quality performance, after-sale service performance and the like is lacked, and due to the neglect of the information, the purchasing closed-loop management cannot be formed, and the risk of winning successful suppliers is increased.
