QUESTION #4
Four delivery trucks are in a queue at a Tool Company with
only one service bay. The trucks are identified by the sequence
in which they arrived at the Company. Assume the time is
10:00 a.m. The table shows the times necessary to unload each
vehicle and the periods when the commodities they contain
are expected in the factory.
Determine the schedules that result for each of the rules SPE,
CR EDD, and FSFC. In each case compute the average tardiness,
the number of tardy jobs, and mean flow time.

QUESTIONS:
1. A refiner in city Q serves four customers near city W and maintains consignment inventory (owned by the refiner) at each location. Currently, the refiner uses TL (truckload) transportation to deliver separately to each customer. Each truck costs $(759) plus $(309) per stop. The refiner is considering aggregating deliveries to city W on a single truck. The demand of the first customer is 75 tons a year, the demand of the second customer is 30 tons per year, and the demand of the third and fourth customers is 10 tons per year. The product cost is $8,000 per ton, and it uses a holding cost of (24)%. The truck capacity is 20 tons.
a. What is the optimal delivery policy to each customer if the refiner ships separately to each of them? What is the annual total inventory-related cost?
b. What is the optimal delivery policy to each customer if the refiner aggregates shipments to each of the four customers on every truck that goes to city W? What is the annual total…

- Question 4 Jo-Jo Inc is a manufacturing firm that produces soap. The company is owned by two brothers, Donald and David Schroeder, and has one plant. The company has experienced significant growth in demand, and the current plant does not appear to have sufficient capacity to meet demand. The company has decided to build a new plant to meet the additional capacity. However, the brothers must decide whether to construct a small, medium, or large plant. The brothers hired a forccasting consultant to predict demand. The consultant's report indicates that there is a 25 percent chance that the demand will be low and a 75 percent chance that the demand will be high. If Jo-Jo Inc. builds a small facility and the demand indeed turns out to be low, the consultant expects net profit of $40 million. If the firm builds a small plant and the demand turns out to be high, then the firm has two options: (1) subcontract or (2) expand the facility. If Jo-Jo Inc. decides to subcontract, the expected net…arrow_forwardLinear Programming question in picturearrow_forwardPlease help to solve question d.arrow_forward

Currently, the DMV uses a single-server, single-line, single-phase system when processing license renewals. Based on historical evidence, the average number of customers arriving per hour is 12 and is described by a Poisson distribution. The service rate is 18 customers per hour with the service times following an exponential distribution. The customers are patient and come from an infinite population. The manager of the DMV would like you to calculate the operational characteristics of the waiting line system. (a) What is the average system utilization?

SVTC is currently evaluating four different approaches to help them maintain their fleet of cars and vans efficiently at the lowest possible cost. Their options are: (1) No preventive maintenance at all and repair vehicle components when they fail; (2) Take oil samples at regular intervals and perform whatever preventive maintenance is indicated by the oil analysis; (3) Perform an oil change on a regular basis on each vehicle and perform repairs when needed; (4) perform oil changes at regular intervals, take oil samples regularly, and perform maintenance repairs as indicated by the sample analysis. Option #1 costs nothing to implement and results in two possible outcomes: There is a .10 probability that a defective component will occur, requiring emergency maintenance at a cost of $1,200, or there is a chance that no defects will occur and no maintenance…arrow_forwardQuestion 27 Finally, passenger rail service comes to Ohio, connecting the six major cities.
