Low-carbon design of leafy vegetable production system based on life cycle analysis and digital model

Environmental problems are common challenges in today's world. Under the requirements of emission peak and carbon neutrality, the research on energy saving and carbon reduction of manufacturing system is the general trend. In the design stage of production system, the demand of capacity and low carbon emission should be taken into account. In this paper, the leafy vegetable production system in protected agriculture is taken as the research object, and the quantitative mathematical model of carbon emission of production system is established based on the whole life cycle analysis, and the digital simulation model of production system is established by Tecnomatix Plant Simulation 15.2. Combining the mathematical model with the simulation model, by designing multi-factor and multi-level simulation experiments, this paper explores the relationship between the design parameters of production system,production capacity and carbon emission, so as to guide the optimal decision of low-carbon design scheme. In the future, the carbon footprint-production system model proposed in this paper can be used to predict and trace the carbon emissions. This paper has certain theoretical and practical significance for the low-carbon research of production system.
