Abstract
This paper conducted a study on the life-cycle engineering cost management of large chemical projects, with the purpose of standardizing the management process and reducing the costs at all stages. Specifically, the LCC analysis method was adopted to analyze the life cycle cost of large-scale chemical engineering projects through detailed introduction to the theory, cost structure and cost analysis steps, based on which the all- factor LCC model of large-scale chemical projects was established. Finally, through the determination of constraints, the optimization of the life-cycle engineering cost model for large-scale chemical projects was realized. This research is helpful to strengthen the engineering cost management for large-scale chemical projects at all stages, and is instructive for the investment decision in large-scale chemical engineering projects.
