| Abstract: | Aiming at the optimization of multi-resource balance considering time value of funds,the optimiza- tion model of multi-resource balance not considering time value of funds is constructed,the static optimization of multi-resource balance in project is realized,and the optimization model of funds for resource is founded consi- dering interest of funds.Based on the above-mentioned models,the mathematic optimization model of muhi-re- source balance considering time value of funds is proposed;the improved genetic algorithm (GA) is expoun- ded,and the capability of GA is enhanced;furthermore,the flow chart of model optimization based on im- proved GA is presented.Practical project analysis is done,and the successful application to the optimization of multi-resource balance in engineering construction shows the feasibility and effectiveness of the proposed meth- od. |
