Low Carbon Emissions Based Economic Optimization Scheme for Prefabricated Construction Supply Planning

According to the “14th Five Year Plan” for the development of the construction industry issued by the Chinese Ministry of Housing and Urban Rural Development, by 2025, prefabricated buildings will account for more than 30% of new buildings. Industrialization and intelligence have become important directions for low-carbon transformation, green development and the realization of dual carbon goals in the construction field. Starting from the perspective of green prefabricated construction management based on carbon reduction, this article considers the multi-stage economic carbon emission balance decision-making of prefabricated construction materials supply planning. The economic-carbon emission balance decision is considered from the perspective of green prefabricated construction management. The equilibrium optimization model is constructed for the prefabricated construction decision makers using multi-objective planning. Through the case study of prefabricated construction and supply planning, the emission reduction effects of production and supply operation of prefabricated building materials in different scenarios are analyzed, and relevant suggestions are also proposed for the practitioners.
