Operation Management Assignment Solution: Location Analysis and More

This document presents a comprehensive solution to an operation management assignment. The solution includes calculations for cycle time, efficiency, and location analysis. The assignment addresses key concepts such as calculating cycle time based on the number of products and available time, determining the minimum number of workstations required for a process, and calculating efficiency. Furthermore, the solution incorporates a location analysis, using weighted scores to evaluate different location options based on factors like material supply, quality of life, climate, and labor skills. The document includes references to relevant operations management textbooks. This assignment is contributed by a student and is available on Desklib, a platform offering various AI-based study tools for students.

Solution 1a
As per layout principle,
As given in question,
2 | P a g e

Question and Answer
No of products = 40
Given time = 8 hr/Shift = 8* 60 = 480 minutes
We know that cycle time ¿ C= t
r where r = no of product and, t = total time
C = 480/40 = 12 minutes Ans
Solution 1b
As given in question,
Total time taken for All task from A to I = 66 min
As from all task A to I, the minimum no of station should be ¿ ∑ t
C = 66
12 =5.5 ≅ 6 station
Therefore, efficiency can be calculated as ¿ ∑ t
nc where n = minimum no of station
= ¿ 66
6∗12 x 100= 66
72 x 100=91.6667 % Ans
Solution 1c
As per minimum no of station, the process will be configured in this way.
Balance delay at each station In minutes

Cycle time delay
T1 A 10 12 =12-10 = 2
T2 B 11 12 =12-11 = 1
T3 C,D,F 12 12 =12-12=0
T4 E 12 12 =12-12=0
T5 G,I 10 12 =12-10=1
T6 H 11 12 =12-11=1
Overall delay in balancing = 100- 91.6667 = 8.333 %

Question and Answer
First I have to calculate the weighted score for all location by the formula = weighted% *
location value. Then I have to calculate the composite score by summing each column, the
highest composite score will have best possible location.
Location
Factor
Weightage Loc. A Loc. B Loc. C Loc. D
Material Supply 10% 5*0.1=0.5 9*0.1=0.9 8*0.1=0.8 7*0.1=0.7
Quality of Life 20% 9*0.2=1.8 8*0.2=1.6 4*0.2=0.8 6*0.2=1.2
Climate 30% 10*0.3=3 6*0.3=1.8 8*0.3=2.4 8*0.3=2.4
Labour Skills 40% 3*0.4=1.2 4*0.4=1.6 7*0.4=2.8 6*0.4=2.4
Score Composite 0.5+1.8+3+1.2
=6.5
0.9+1.6+1.8+1.6=
5.9
0.8+0.8+2.4+2.8
=6.8
0.7+1.2+2.4+2.
4=6.7
From the calculated composite score, the score of location C is highest; therefore,
location C is best possible location
