| dc.description.abstract | In recent years, due to the improvement of people′s living standards, the rapid development of industry and commerce, the population has surged, and the demand for tap water quality has become increasingly intense. The main factors affecting the taste of tap water are odor and hardness. If it is not boiled, the odor is the main factor. In order to improve the drinking quality of tap water, such as taste, taste, hardness, etc., the equipment of the water purification plant is upgraded and improved to ensure the safety of drinking water. This research focuses on consideration.
According to the contract requirements of a construction engineering company, this study uses the linear integer programming optimization model to obtain different types of inspectors for the performance of equipment maintenance and mechanical and electrical, civil engineering, environmental engineering and other inspection projects in various districts. Execute the manpower assignment of the audit, and provide a reference for decision makers to assign power. In order to verify the above problems, this research aims at the applicability of the planning and design mode according to the individual requirements and constraints set by the personnel assigned by the annual inspection team, and sets the constraints for the compilation and assignment of the inspection team, and establishes a set of optimal integer programming mathematical models. And use LINGO 17.0 software to solve. | en_US |
