a) The network below describes a project consisting of eight subtasks (A, B, C, D, E, F, G, H). The arcs of the network describe sub-tasks and the durations of the sub- tasks are indicated in connection with the arcs. What are the duration of the project, the earliest (ET(i)) and latest (LT(i)) event times for the nodes, and the allowances for subtasks? What is the project's critical path? 1 A2 2 B6 C4 4 E2 D4 F1 H1 G2 b) Let's mark the event moment of node i with the variable xi, where i = 1, 6. Formulate an Lp-model whose decision variables are the variables xi and the goal is to minimize the event moment of the decision node under the constraints related to subtasks.
