Concept explainers
a)
To determine: The offered load.
a)
Explanation of Solution
Given information: The following information are provided in the problem about company LARA,
Calculation of offered load:
.
Offered load is the ratio of average processing time (p) to average interarrival time (a) that is 3 hours divided by 0.5 hours gives 6 as offered load.
b)
To determine: Implied Utilization.
b)
Explanation of Solution
Given information: The following information are provided in the problem,
Calculation of implied utilization:
Implied utilization is the ratio of average processing time to the product of average interarrival time and number of servers. Therefore 3 hours divided by the product of 0.5 hours and 5 reporters gives the implied utilization of 1.2.
c)
To determine: The capacity to complete the assignments.
c)
Explanation of Solution
Given information: The following information are provided in the problem,
Calculation of capacity:
Capacity to complete the assignment is the ratio of number of resources to the average processing time which is product of 5 reporters with 3 hours gives the capacity as 1.67.
d)
To determine: The probability that an incoming text message is not pursued.
d)
Explanation of Solution
Given information: The following information are provided in the problem,
Calculation of probability that three pumps are being used by that an incoming text message is not pursued:
Probability that incoming text message cannot be pursued can be found from Erlang loss table, for r is 6 and number of server m is 5, the corresponding value is 0.3604. Therefore, probability that incoming text message cannot be pursued is 0.3604.
e)
To determine: Flow rate of completed assignments.
e)
Explanation of Solution
Given information: The following information are provided in the problem,
Calculation of flow rate of completed assignments:
The Flow rate of completed assignments is 1.28.
f)
To determine: Utilization of LARA reporter.
f)
Explanation of Solution
Given information: The following information are provided in the problem,
Calculation of utilization:
Utilization is calculated by dividing flowrate with capacity which is the ratio of 1.28 to 1.67 which yields 0.77.
g)
To determine: The number of reporters needed for 85% of the text message to be attended.
g)
Explanation of Solution
Given information: The following information are provided in the problem,
Calculation of number of reporters:
Probability
For r = 6 & Pm as 0.15, the number of operators required is between 7 and 8.
Therefore, the number of reporters required for 85% of text messages to be attended is 8.

The demand for subassembly S is 100 units in week 7. Each unit of S requires 1 unit of T and 2 units of U. Each unit of T requires 1 unit of V, 2 units of W, and 1 unit of X. Finally, each unit of U requires 2 units of Y and 3 units of Z. One firm manufactures all items. It takes 2 weeks to make S, 1 week to make T, 2 weeks to make U, 2 weeks to make V, 3 weeks to make W, 1 week to make X, 2 weeks to make Y, and 1 week to make Z.

- 3. WestJet’s daily flight from Edmonton to Toronto uses a Boeing 737, with all-coach seating for 120 people. In the past, the airline has priced every seat at $140 for the one-way flight. An average of 80 passengers are on each flight. The variable cost of a filled seat is $25. Katie Morgan, the new operations manager, has decided to try a yield-revenue approach, with seats priced at $80 for early bookings and at $190 for bookings within one week of the flight. She estimates that the airline will sell 65 seats at the lower price and 35 at the higher price. Variable cost will not change. Which approach is preferable to Ms. Morgan?arrow_forward2. A large Saskatchewan feed mill, B. Swart Processing, prepares its sixty-month aggregate plan by forecasting demand for 50-pound bags of cattle feed as follows: January, 1000 bags; February, 1200; March, 1250; April, 1450; May, 1400; and June, 1400. The feed mill plans to begin the new year with no inventory left over from the previous year, and backorders are not permitted. It projects that capacity (during regular hours) for producing bags of feed will remain constant at 800 until the end of April, and then increase to 1100 bags per month when a planned expansion is completed on May 1. Overtime capacity is set at 300 bags per month until the expansion, at which time it will increase to 400 bags per month. A friendly competitor in Alberta is also available as a backup source to meet demand—but can provide only 500 bags total during the six-month period.
