Abstract:Digital service platform is an efficient way to manage modern enterprises. In order to effectively solve the contradiction between construction tasks and personnel, equipment and other resources, ensure the health and continuous development of power transmission and transformation construction enterprises and the safety and quality of construction projects, in view of the problems such as overcapacity engineering, increased safety risk, and difficult to guarantee the quality of engineering, from the practical demands and based on business intelligence technology, this paper presents an engineering capacity evaluation system for transmission substation construction companies, against the background of the engineering evaluation standard for Sichuan power transmission and transformation construction enterprises. An engineering capacity calculation model was built by establishing human resources and equipment resources data warehouse. Meanwhile, situation assessment of projects and planning of construct enterprise are realized to improve the risk control capability and operational decision-making capacity. The system has a wide application prospect. The application results show that the evaluation system is scientific, reasonable, practical and effective, and has a good guiding significance for construction enterprises. It provides useful reference and basis for enterprises to rationally arrange work tasks and sternghen safety and quality management.
