Bidding method and system based on carbon emission

Abstract

The invention relates to the technical field of data analysis, in particular to a bidding and tendering method and system based on carbon emission, and the method comprises the steps: carrying out the calculation and analysis through a Monte Carlo simulation technology according to the expected construction price and the expected total construction price of a bidding construction unit, and obtaining an optimal environment weight; according to the optimal environment weight, environment cost is quantified for each bidding construction unit according to the net carbon emission and the set environment weight, a currency value corresponding to the environment cost is obtained, the total construction price of the construction unit is obtained according to the currency value and the actual bidding construction price of the construction unit, and the total construction price of the construction unit is obtained according to the total construction price. And determining the construction unit winning the bid. According to the scheme, the carbon emission can be quantified efficiently and accurately, the problems of uncertainty and generalization of environmental weights are solved, and the practicability, simplicity and generalizability of the method are improved.

Description

Technical field [0001] The invention involves the field of data analysis technology, which is specifically a carbon -based bidding method and system. Background technique [0002] Because the bidding mechanism of traditional engineering construction is based on cost and construction period as the main consideration, and does not support the concept of sustainable development. In the long run, it will cause irreversible damage to the environment. With the modernization of my country's construction industry, the bidding for engineering construction has become an important means for the bidding party to choose from the construction unit. In the traditional bidding mechanism, there is no objective consideration to be objectively considering the weight of green environmental protection. It does not meet the concept of sustainable development. Although there are some engineering construction bidding start to consider sustainable development, it is practical and simple. And promotional,...

Problems solved by technology

The traditional bidding mechanism does not systematically and objectively consider the weight of green environmental protection, which does not conform to the concept of sustainable development. Although some engineering construction bidding has begun to consider sustainable development issues, its practicality and simplicity and generalizability, are severely constrained at the technical level, such as:

[0003] 1. There is no efficient and accurate quantification method for estimating the carbon dioxide emissions generated during the operation of construction machinery and equipment (hereinafter referred to as carbon emissions). Specifically, it is difficult to actually measure the carbon emissions generated by on-site construction, and it is impossible to measure accurately and efficiently , the cost is high; and in the bidding process, the construction unit has not yet entered the construction site to start construction, and the actual carbon dioxide emissions during the construction stage cannot be obtained during the bidding process. Of course, in order to solve this problem, researchers have carried out some related research, such as According to the data collected by the corresponding experiments, the carbon emissions of a certain material (such as fuel) in a certain working environment can be obtained, and the corresponding calculation formulas can be used to calculate the carbon emissions. However, its shortcomings are also obvious. Need Enter detailed calculation parameters (temperature, use environment, fuel type, etc.), some of which cannot even be quantified

[0004] 2. Even if the carbon emissions are accurately quantified in the bidding process, it is impossible for any project to only consider the carbon emissions without considering the cost, so the quantified carbon emissions can only be a reference factor in the bidding, By converting it into environmental weights, it will have a certain impact on the bidding results, but there are uncertainties and generalization problems in the predetermined environmental weights, and the determination of environmental weights through historical data and analysis techniques will face the challenge of large data sets. The process is lengthy and cannot well address the inherent dissimilarity in the bidding prices provided by the construction unit, as well as the uncertainty of carbon emissions due to other factors

[0005] The above problems all severely limit the practicality, simplicity and generalizability of the bidding method considering the green environment
