Expected duration for the completion of the project. Calculate earliest and latest start and finish times for each activity.
Draw the network diagram for the project and determine the critical path
The activities of a project, their normal and shortest completion times in days, their respective completion costs in euros, and the constraints on their execution sequence are presented in the table below. Questions: A) To build the network that graphically illustrates the project. B) To find the shortest and slowest start and end times. C) Find the critical path and calculate the total cost. D) To consider the case of reducing the total duration of the project by 1 day at the lowest possible cost.
Find the project duration after constructing the network diagram by using the data provided in Table.
