Frame type bidding and tendering management platform for shell-and-tube heat exchanger

Abstract

The invention provides a frame-type bidding and tendering management platform for a shell-and-tube heat exchanger. The frame-type bidding and tendering management platform comprises a server, and a first-stage bidding module, a first-stage bidding evaluation module, a second-stage bidding module and a second-stage bidding evaluation module that are communicated with the server, wherein the first-stage bidding module comprises a main material quotation sub-module and a variable part quotation sub-module; the first-stage bidding evaluation module comprises a main material quotation evaluation sub-module, a variable part quotation evaluation sub-module, a weight coefficient sub-module and a price comprehensive evaluation sub-module; the second-stage bidding module comprises a secondary quotation sub-module; and the second-stage bidding evaluation module comprises a variable part final quotation evaluation sub-module and a second-stage comprehensive bidding evaluation sub-module. On one hand, the purchasing transparency of the shell-and-tube heat exchanger is improved, and on the other hand, the framework protocol can flexibly adapt to the condition of purchasing demand change caused by design change, so that the purchasing supply business management level is further promoted.

Description

technical field [0001] The invention relates to a material procurement management platform for engineering construction projects in the field of energy and chemical engineering, in particular to a frame-type bidding management platform for shell-and-tube heat exchangers. Background technique [0002] In the material procurement of engineering construction projects in the traditional energy and chemical industry, procurement personnel can carry out follow-up bidding, bidding, bid evaluation, bid determination, and contract signing after receiving a specific procurement demand. This kind of procurement business is "one-to-one". On the one hand, it cannot effectively integrate material needs, and the negotiation weight with suppliers is relatively light, and the space for cost reduction is limited; on the other hand, business personnel repeat operations at a low level day after day, and the labor intensity is high. , Procurement efficiency is low. [0003] The investment in en...

AI Technical Summary

Problems solved by technology

However, in the traditional frame bidding mode, there is no good solution for how to set up the price adjustment mechanism in the frame of the shell-and-tube heat exchanger. When the range is above (such as ±5%), the equipment price will be adjusted accordingly (such as ±3%)

This is precisely the problem caused by the simple and extensive measurement method mentioned above for the price of equipment

[0012] Therefore, the procurement of shell and tube heat exchangers in refining and chemical units cannot achieve a more sci
