Answer:
The lowest cost ( Z ) will equal $636 daily
quantity of permanent operators = 6
quantity of temporary operators = 3
Explanation:
based on the provided information: the organization has a total of ten (10) workstations and employs both permanent and temporary operators; the following demonstrates the work that can be performed with these resources
Orders processed each day
permanent operator; 76
temporary operator; 53
company average: minimum of 600
Errors recorded daily
permanent operator; 1.3
temporary operator; 4.1
acceptable maximum error rate: 24
daily wages; permanent ($81), temporary ($50)
formulate an integer programming model to ascertain the number of permanent and temporary operators needed to minimize costs
Let X1 represent the permanent operators and X2 represent the temporary operators
the daily operator cost can be expressed as ( Z ) = 81 X1 + 50 X2 (first constraint)
operators at workstations = X1 + X2 ≤ 10 (second constraint)
Total orders handled = 76 X1 + 53 X2 ≥ 600 (third)
allowable errors permit = 1.3 X1 + 4.1 X2 ≤ 24 (fourth constraint)
Operators must be whole numbers = X1, X2 ≥ 0 (fifth constraint)
construct an Excel linear program incorporating both the data provided and the constraints formulated.
The lowest cost ( Z ) will equal $636 daily
quantity of permanent operators = 6
quantity of temporary operators = 3
