Coordination And Optimization Of The Engineering Projects

The purpose of engineering project control system decision is to obtain an optimum method. To evaluate a project schedule should consider comprehensively the technology and economic indexes, which conclude time, cost and resources. However, it is not reached in theory and in practice. Base on the principles of system analysis, a generalized optimization method of engineering projects control system is given which carries out the idea of dynamic optimization management. This paper put forward a comprehensive optimum method that consider three indexes such as time limit for a project, cost and resources, and use two-code network plan to achieve a series of solutions. Base on the principles of system analysis and correlation, this paper presents a coordination degree model in the decision process, which aims to evaluate and obtain the optimum solution.Firstly, we use the algorithm of the least cost scheduling in network plan. And a useful heuristic model described as the Latest Finish Time Model for resources scheduling is selected to solve the resource optimization, which based on investigation of heuristic methods of resource-constrained activity network. Finally, to evaluate and obtain the optimum solution using the coordination degree model in the decision process. Furthermore, the optimization is proved to be an effective method from an algorithm and a numerical example. This method has been applied to highway projects and satisfying effects was obtained.The project scheduling control is a dynamic control procedure but not static. In the engineering project management, once get deviation from the plan, we can carry out the control decision by using this synthetic optimization method to correct and improve the control station. Through the dynamic control, the subsystem can carry out coordinately, and the system aim can accomplish.
