Research from the research status of investment in construction, the implementation process in accordance with the construction project, followed by analysis of the construction project investment the currently existing problems, and puts forward the implementation of the project the whole process as the main line, to scientific decision-making, rational design, bidding, construction control standard and completion of review strategies as the core.展开更多

In order to maximize performance, both the client and the contractor will work to optimize both the duration of the project and its cost. We show a model of linear entire mixed programming to solve the considered problem. The aim is to minimize the project total time, by means of the assignment of equipments of work to the different production lines of the activities to realizing. The fundamental beginning is to support the same production （rate of production in meters/day of the activity in view of the equipment of work） for tbe different equipments to achieve the maximum efficiency in each period of time. With the limited availability of resources, the work must be continuous and the period of time between operations and final must be kept. However, this paper also presents the bibliographical study on methodologies of the optimization of construction processes in response to the two objectives： time and cost. This will consider the use of recta-heuristic techniques, such as population based algorithms.展开更多
