本文以概率论为基础,讨论了工厂供电系统设计的实用优化技术,提出了在多目标条件下确定最优供电设计方案的比较评分法,并建立了供电设计实用决策模型。此法简单易行。 Based on the theory of probability, this paper discusses the practical optimization techniques for the design of power supply system in the factory, puts forward the comparative grading method to determine the optimal power supply design scheme under multi-objective conditions and establishes a practical decision model for power supply design. This method is simple and easy.
