Prefabricated House Precast Part Project Scheduling Optimization Problem Based on Network Planning

Abstract

Project scheduling has been the core of project management, whose largest characteristics are the limitation of resources and the diversity of activity modes. And the prefabricated building has become the most potential building form due to the promotion of policies and its own unique advantages. However, the unreasonable project scheduling might cause some problems, such as resource waste problem. This study established the mathematical model for multi-mode resource constrained project scheduling problem on Prefabricated house precast parts project, which realized the comprehensive optimization of time and cost under the condition of satisfying the constraints of logical relation and resource. And then the problem was solved by Cplex in Python, the optimized scheduling scheme was also obtained. It might provide reliable basis for project management.
