MGMT335 HW3 (2) Compatibility Mode Mailings Review View Help Tell me what you want to do MGMT 335 HW#3 Please solve the folloving problems related to Chapter 17: Project Management 1. Based on the following AOA diagram, please answer the following question: (1) Determine the cntical path and the expected project duration (2) Determine the following quantities for each activity: the earliest start time, the latest start time, the earliest finish time and the latest finish time and the slack time. F (5) 1 (8) G ( B (8) E (12) 2 A project manager has compiled a list of major activities that will be required to install a computer information system in her firm. The list includes the precedence relationships and estimated completion time for each activity. Please compute the expected time and standard deviation for each path

Answer 1

Different paths are as below: A-C-F-l-4+7+5+8-24 A-D-G-4+11+3+8 -26 B-E-H -8+12+10 30 4 10 17 s) 26 0 4 n 15 15 G ( 19 19 22 20 Ho30 0 B (8) AS THE MAXIMUM LENGTH IS OF B-E-H THUS THE CRITICAL PATH WILL BE B-E-H E (121 30 0 20 The expcted project duration is the time of critical path i.e. 30

Activity	Duration	EST	LST	EFT	LFT	SLACK
A	4	0	4	4	8	4
B	8	0	8	0	8	0
C	7	4	11	10	17	7
D	11	4	15	8	19	11
E	12	8	20	8	20	0
F	5	11	16	17	22	5
G	3	15	18	19	22	3
H	10	20	30	20	30	0
I	8	18	26	22	30	8

Answer 2:-

Activity	Optimistic	Most Probable	Pessimistic	Expected completion time	Expected compleetion time	Standard deviation
A	5	9	10	(5+4*9+105)/6	8.50	0.83
B	6	7	10	(6+4*7+10)/6	7.33	0.67
C	4	5	6	(4+4*5+6)/6	5.00	0.33
D	4	5	7	(4+4*5+7)/6	5.17	0.50
E	7	9	11	(7+4*9+11)/6	9.00	0.67
F	4	5	8	(4+4*5+8)/6	5.33	0.67
G	6	8	10	(6+4*8+10)/6	8.00	0.67
I	5	6	9	(5+4*6+9)/6	6.33	0.67
	Formula for Expected completion time = (O+4M+P)/6
	Std.Deviation = ((P-O)/6)

PLEASE RATE THE ANSWER AS THUMBS UP. THANKS A LOT.
