Document Summary
Tasks in a project might have precedence relations (b must happen after a) or parallel activities (a and b can happen at the same time; independent) Drawing project networks: activity on node (aon) -> nodes designate activities. A node is represented by a circle, indicates an activity, a time consuming effort that is required to perform a part of the work. An arrow indicates the direction/flow of the activities: no arrows -> all activities can be done at the same time (independent) Activities leaving a node can not begin until all the activities entering the node are completed. There is a single starting node which has only outflow arrows, and a single ending node which have only inflow arrows. There is no cycles in the network. Step 1 forward pass: for each activity i beginning at the start node, compute:
