Formulate a system of equations for the situation below and solve.

A manufacturer of women's blouses makes three types of blouses: sleeveless, short-sleeve, and long-sleeve. The time (in minutes) required by each department to produce a dozen blouses of each type is shown in the following table.

Sleeveless Short-
Sleeve
Long-
Sleeve
Cutting  9 12 15
Sewing 22 24 28
Packaging  6  8  8

The cutting, sewing, and packaging departments have available a maximum of 87, 176, and 52 labor-hours, respectively, per day. How many dozens of each type of blouse can be produced each day if the plant is operated at full capacity?

sleeveless      dozen
short-sleeve      dozen
long-sleeve      dozen

Solutions

Expert Solution

Variable

no. of blouses in dozen for sleeveless = b

no. of blouses in dozen for short sleeve= s

no. of blouses in dozen for long sleeve = l

constraints

1. b,s,l should be non-negative integers

2. total cutting time should not exceed 87, 18s+24s+45l <= 87

3. total sewing time should not exceed 176, 44s+48s+84l <= 176

4. total packaging time should not exceed 87, 12s+16s+24l <= 52

objective

complete capacity of all the dept. are used.

capacity utilization short = (18s+24s+45l - 87) + (44s+48s+84l - 176) + (12s+16s+24l - 52) = 0

solution

Sleeveless Short-sleeve Long- sleeve Total spent Total available constraint
optimal qt. 2 2 3
Per piece time Cutting 9 12 15
Sewing 22 24 28
Packaging 6 8 8
Total time Cutting 18 24 45 87 87 0
Sewing 44 48 84 176 176 0
Packaging 12 16 24 52 52 0
Objective is to get the no. of labor hours of each activity is fully used.

0

so answer is sleeves 2 dozens

short sleeves = 2 dozens

long sleeve = 3 dozens
