Exercise 1 Given the following inputs: a) The activity Description Table (see below) b) The availability of 4.000 to be used for shortening (e. crushing) the project's duration c) The overall objective to minimize the project's duration Calculate 1. The project durations (normal and crushed); 2. The total project costs (nonnal and crushed): 3. The critical paths (normal and crushed); 4 The CPM network (AON notation) (normal and crushed); 5.
