Technical Field
[0001] This invention belongs to the field of lifecycle management technology, and relates to a management system and method based on the entire lifecycle of an engineering project. Technical Background
[0002] The rapid development of the construction industry and the dramatic increase in the size of the construction market have led to increasingly serious environmental problems, severely limiting the sustainable development of the construction industry. The greenhouse effect caused by carbon dioxide emissions is particularly prominent. Construction, industry, and transportation are currently recognized as the three major sources of carbon emissions worldwide. In order to deeply integrate the concept of green building into the construction industry and enable its healthy and sustainable development, while reducing its environmental impact, it is crucial to study the carbon emissions throughout the entire life cycle of buildings.
[0003] The existing building lifecycle carbon emission management still has some areas that need to be optimized, specifically in the following aspects:
[0004] 1. Current analysis of carbon emission management throughout the building lifecycle has certain limitations, which to some extent hinders the improvement of the intelligence level of green buildings. It is no longer able to adapt to the increasingly intelligent building level, and cannot perceive the current status of building carbon emissions from multiple angles and levels. As a result, the management level of carbon emission throughout the building lifecycle cannot adapt well to the needs of economic and social development, and cannot reduce the economic losses directly caused by carbon emission reduction management throughout the building lifecycle. It may also indirectly cause secondary disasters, and affect building management capabilities and operational efficiency.
[0005] 2. Current analysis of carbon emission management throughout the building lifecycle has certain drawbacks. It fails to achieve the goals of energy conservation and consumption reduction, and improve the level of intelligent building management. It reduces the comfort of the building environment, causes energy waste to a certain extent, is not conducive to saving building operating costs, increases the economic burden of building operation, and also goes against the trend of energy conservation and environmental protection.
[0006] 3. Currently, it is impossible to effectively guarantee the comprehensiveness of building lifecycle carbon emission management monitoring and analysis, the scientific nature and reliability of building lifecycle carbon emission management analysis, and it is also impossible to provide accurate data for the future, thus failing to improve the accuracy of building lifecycle carbon emission management. Summary of the Invention
[0007] In view of the problems existing in the prior art, the present invention provides a management system and method based on the entire life cycle of engineering projects to solve the above-mentioned technical problems.

[0064] The production stage calculation module is used to analyze the carbon emissions of each building in the target area corresponding to the production stage.
[0065] As a preferred embodiment, the analysis of carbon emissions for each building within the target area at its corresponding production stage includes the following steps:
[0066] Obtain the location of each building within the target area and import it, along with the locations of the ordering stores for each building material at each production stage, into a 3D map model. This yields the transportation distance between the location of each building within the target area and the ordering store locations for each building material. This distance is then marked as the reference transportation distance between the locations of each building and the ordering store locations for each building material within the target area. Where r represents the number of each building to be built, r = 1, 2, ... p, and f represents the number of each building material, f = 1, 2, ... q;
