Mueller & Associates is a urban planning firm that is designing a new public park in an Omaha suburb. Coordination of the architect and subcontractors will require a major effort to meet the 43-week completion date requested by the owner. The Mueller project manager prepared the following project network.

A project network with 10 activities and 14 directed arcs is shown.

Activity Start is connected to activity A.
Activity A is connected to activity B, to activity C, and to activity D.
Activity B is connected to activity F.
Activity C is connected to activity E and to activity F.
Activity D is connected to activity E.
Activity E is connected to activity G and to activity Finish.
Activity F is connected to activity G and to activity H.
Activity G is connected to activity H.
Activity H is connected to activity Finish.
Activity Finish has no arcs directed to other activities.

Estimates of the optimistic, most probable, and pessimistic times (in weeks) for the activities are as follows.

Activity	Optimistic	Most Probable	Pessimistic
A	4	8	12
B	6	7	8
C	6	12	18
D	3	5	7
E	6	9	18
F	5	8	17
G	10	15	20
