1.All the following statements are true about using linear programming in project scheduling, EXCEPT:
Select one:

a. The Earliest Finish time of each activity is determined from the solution of the model

b. The formulation of the mathematical model involves determining the decision variables, determining the objective function, identifying the constraints, and determining the values of the parameters

c. The non-negativity constraints must be included in the model formulation

d. all statements are true

e. Two mathematical models need to be developed and solved, one dealing with the earliest start time and the other one dealing with the latest starting time. However, it does not matter which one is solved first.
