Time-cost trade-off theory, quantitative and accounting analysis of the process of implementing economic projects

This study aims to provide quantitative indicators to the decision-maker regarding the time-cost exchange to speed up the completion process of projects by raising cost levels, as well as providing quantitative indicators to the decision-maker regarding the possibility of reducing costs by opening the time limit for completion and highlighting the role of quantitative methods in implementing the time-cost-exchange process, to obtain financial indicators, and this comes as a solution to the problem of whether it is possible to exchange time for cost and vice versa to implement tasks and activities for different projects in economic units. This study found the possibility of postponing the required accounting payments for the project periods if the C.P.M method is adopted. Cash dues or the required installments can be paid for the project’s last third or fourth quarter.
