Optimization Model of Program Employer's Cost with Periodic Forbidden Time Window Under the Constraint of NCRPE
The contracted project with a periodicity forbidden time window(special contracted project for short)is the key to affect the implementation effect of the program.How to effectively control the progress of the contracted project with periodicity forbidden time window is not only a theoretical problem,but also a practical problem.First,the problem is defined,the principle of employer cost optimization of program is analyzed in detail,and the special contracted projects are divided into two categories:contracted projects that can be completed within the original time window and contracted projects that can be completed in the next time window.Then,considering the particularity of the contract project with a periodic prohibition time window,an optimization model of the program owner's cost before and during the implementation of the program are constructed.Afterwards,a case study was conducted in combination with program R to verify the feasibility and effectiveness of the model.Finally,the management enlightenment is proposed.The research results show that in the program with a periodic forbidden time window,the degree of adverse impact of contracted project delay on the program depends not only on the degree of adverse impact on general contracted projects,but also on whether special contracted projects can be completed within the original planned time window.To this end,the employer should improve the probability of completing the special contracted project within the original time window by arranging the start time of the program and the special contract,so as to significantly reduce the cost of the program employer.
