In case of convergent event, select the highest EST out of different paths. Earliest finish time (EFT) = Earliest finish time of previous or tail event + time of the activity. Forward Pass of event : adding activity time from left to right. Total cost of a project = cost of all the activities in the project + Indirect cost or Overheads during the project duration 9. All activities lying in this critical path are called critical activities as any delay in their execution will lead to a delay in the completion of the entire project. Critical Path: The longest time duration path is known as critical path & represented by thick line or double lines. Time of a path = time of the activities in that path. Path or Route : a series (one by one) of activities taken together to link the first & end event of an project. Between two events there must be only one activity. The activity so starts from predecessors is known as successor. an activity(s) must be completed first to start the following Activity(s). Sequence : activities of a project are linked in a sequence known as immediate predecessor i.e. Similarly all end activities will merge to that single event. All starting activities will starts from that single event. Every project or network diagram starts with a single event & ends at a single event. It does not consume any time or resource as it it is an indicator only. so that it moves from lower to higher no. Event : it denotes the start (tail) & end (head) of an activity & represented by a circle both at the start & end of the activity.

It is shown as & represented by a capital letter A,B,C etc. Activity : It is a particular work of a project which consumes some resources (in ) & time. 1 Network analysis: P.E.R.T,C.P.M & Resource Allocation Some important definition: 1.
