Problem 1: Given the information provided below (predecessors, normal time, normal cost, crash time and crash cost for an eight-activity (a to h) project) answer the questions (a) through (e) using this template. Note: If there are no adequate explanations, points will be deducted even if the answers are correct.

Activity	Predecessor	Normal Time	Normal Cost	Crash Time	Crash Cost	Crash Cost/Day
a	-	5	$50	3	$150
b	-	4	40	2	200
c	b	7	70	6	160
d	a, c	2	20	1	50
e	a, c	3	30	-	-
f	b	8	80	5	290
g	d	5	50	4	100
h	e, f	6	60	3	180

(a).Create the network diagram in the application of your choice and then insert a screen shot of the diagram here. The diagram can be created easily in MS Word using the Insert Shapes function.

Identify the critical path of the network, the time, and cost of the normal level of activity for the project:

• The critical path is: __________________

• The project duration: ___________

• The project cost is: _____________

(b).Calculate the crash cost-per-day (all activities may be partially crashed). Enter your response to question 1(b) in the table provided below

Activity	Normal Time	Normal Cost	Crash Time	Crash Cost	Crash Cost/Day
a
b
c
d
e
f
g
h

(c). Find the optimal way of getting an 18-day delivery time. What is the projected cost? Once youve found the solution, explain the results of your calculations. You can use Excel to show your answers. Please do not use any excel add-ons such as Solver to solve this.

(d). Find the optimal way of getting a 16-day delivery time. What is the project cost? Explain your results. You can use Excel to show your answers. Please do not use any excel add-ons such as Solver to solve this.

(e). Calculate the shortest delivery time for the project. What is the cost? Explain your results. You can use Excel to show your answers. Please do not use any excel add-ons such as Solver to solve this.
