The Influence Of Special Procedure On Time-cost In The Overlapped Network

The research on time-cost optimization problem started from the early 1960s. However, no breakthrough has been made with regard to the solution of the problem in the overlapped network. The main reasons are as follows:the single code overlapped network cannot express specific time parameters, and the different influences of special procedures'periods on the project period are not in-depth analysis.In view of the above two reasons, the thinking of transformation is introduced in this paper. Firstly, transforming an AoN overlapped network into an AoA network through standard form is made. Then, the influences of special procedures'periods on the project period are analyzed, such as bi-critical, backward-critical, start-critical, and finish-critical. Finally, a time-cost optimization problem of finishing the project under the deadline restriction with minimum total cost is solved through an example based on analyzing project cost. Therefore, the study made in this paper is not only of theoretical significance but also of great practical value.
