Rahat engineering has been assigned to develop a project that is a construction P1 based project. This project is the combination of multiple dependent and P2 P5, P7, P8 independent project modules. Company is in real trouble in estimating the total P3 time to develop the whole project [when their engineers try to estimate the total time of the project every time project estimated time comes different]. P5 First four modules individually take one week to be completed and the last 5 P6 modules individually take two weeks to completed. You have to design a P7 P8 solution [algorithm, with the help of the graph], that can solve the current P8 problem [to estimate the total time to complete the project] faced by Rahat engineering. [Exact solution or the pseudo solution] P2, P4 P6 P4 P7, P9 P4, P6 P7 P2, P4 P9 3, 5, 6 You have to first solve the problem that why this project estimation is not right and then after that when project starts at one time at max two activities can be done if possible but not more than two at one time.
