摘要
工程计价费用标准是建设项目造价确定的重要依据,对于精准投资和价格科学形成具有重要影响。随着电力工程建设新型技术的发展应用,现行工程计价费用标准的测算与管理面临着新的发展要求与挑战,优化电力工程计价费用标准测算流程具有现实意义。本文将灰色关联分析法、蒙特卡罗模拟法等数理统计理论与方法应用于费用标准测算工作的因素分析、水平测算、检验验证等关键模块,形成一套科学高效的基于GRA-MC的电力工程计价费用标准测算优化方法体系。并以A类型变电站工程中垂直运输费用标准测算为例进行实证分析,研究结果显示:测定的垂直运输费用标准具有一定的代表性及覆盖性,能够作为指导实际工程费用标准测算及水平分析的参考依据,可为费用标准高效更新调整与工程投资精益化管控提供有益参考。
The engineering pricing cost standard is an important basis for determining the cost of construction projects,and has a significant impact on precise investment and scientific pricing formation.With the development and application of new technologies in power engineering construction,the calculation and management of current engineering pricing cost standard face new development requirements and challenges.Optimizing the calculation process of power engineering pricing cost standards has practical significance.This article applies mathematical statistical theories and methods such as grey correlation analysis and Monte Carlo simulation to key modules such as factor analysis,level calculation,and verification in cost standard calculation,forming a scientific and efficient optimization method system for power engineering pricing cost standard calculation based on GRA-MC.Taking the calculation of vertical transportation cost standards in A-type substation engineering as an example for empirical analysis,the research results show that the measured vertical transportation cost standards have certain representativeness and coverage,and can serve as a reference for guiding the calculation and horizontal analysis of actual engineering cost standards.It can provide useful reference for efficient updating and adjustment of cost standards and lean management of engineering investment.
