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.

QUESTION 5
Regional Airlines is establishing a new telephone system for handling flight reservations. During the 10:00 AM to 2:00 PM time period,
calls to the reservation agent occur randomly at an average rate of one call every 3.75 minutes. Historical service time data show that a
reservation agent spends an average of 3 minutes with each customer. The waiting line model assumptions of Poisson arrivals and
exponential service times appear reasonable for the telephone reservation system.
At a planning meeting, Regional's management team agreed that an acceptable customer service goal is to answer at least 75% of the
incoming calls immediately. During the planning meeting, Regional's vice president of administration pointed out that the data show that
the average service rate for an agent is faster than the average arrival rate of the telephone calls. The vice president's conclusion was
that personnel costs could be minimized by using one agent and that single agent must be able to…
Question : One way for a manager of a property to increase the net operating income of a retail store is to increase the flow of customer traffic into the store. If the increased traffic results in increased sales, then the net operating income of the store will increase. If this can be sustained then the manager has increased the value of the property.

- QUESTION 1 A multiple channel queuing system with a Poisson arrival rate, and an exponential service time distribution has an average arrival rate of 2.5 customers per hour and an average service time of eighty minutes per customer. A queuing system is described as unstable or overloaded if its utilization rate is greater than, or equal to one. For the system just described, what is the minimum number of servers required to retain stability i.e., to avoid overloading? A. 3 B. 2 C. 4 D. 1 QUESTION 2 Customers arrive at the lone check-out desk of a certain convenience store at the average rate of 0.23 per minute. If it takes on average four minutes for the store manager to serve each customer, how many customers will on average find themselves waiting in the queue?

The dealer can buy the painting today for $40,000 or can wait a day and buy the painting tomorrow (if it has not been sold) for $30,000. The dealer may also wait another day and buy the painting (if it is still available) for $26,000. At the end of the third day, the painting will no longer be available for sale. Each day, there is a 0.60 probability that the painting will be sold. Construct a decision tree and determine the strategy that will maximize the dealer's expected profit.arrow_forwardQuestion 3 Not yet answered Marked out of 1.00 P Flag question Abdullah is engaged in a business where he uses his creativity to produce shoes from animal skin.

- QUESTION 5 A post office has a counter for customers' drive-through to get the services. The design of the drive-through lane allows for unlimited queue length. The arrival and service rate are Poisson distributed with A= 20 customers per hour arriving on average and u=25 customers per hour can be served on average. a) Compute the average number of arrivals. b) Compute the average time a customer waits. c) Compute the average number of arrivals in the system. d) Compute the average time a customer is in the system. e) Compute the probability that less than or equal to 3 customers are in the system. f) If the single counter for the customer drive-through has been replaced with the automatic operation, service rates are constant with A= 20 and u =25. Compute (a), (b), (c) and (d).arrow_forwardQuestion 40 of 50 Francesca is helping a customer troubleshoot a software program and determines the customer needs to update their software. What is the best way to communicate this to avoid making the customer feel defensive? "You haven't kept your software updated, which is why it isn't working. Do you know how to run an update? If not, I can walk you through the steps." "I think that your software isn't working because you haven't run an update lately. May I walk you through the steps?" "A lot of customers don't know how to run a software update, but I can walk you through the steps." "I think we can solve the issue by updating your software. May I walk you through the steps?"arrow_forwardQuestion related to gueing theory don't copy In a restaurant, two types of foods are available. Arival rate of customers is 26 per hour Poisson and average service time is 6 minutes exponential. The arriving customers can be served in three ways. The first way is to open two separate counters for the two types of foods. The second way is to pool the services, and offer both types of foods in both the counters. The third way is to open a large number (0) of self-service counters for the customers. Which way will lead to the maximum busy period of the system? wwmarrow_forward

- dent question I am having trouble formulating the objective function and constraints. Jeremy Manufacturing Company produces connecting rods for 4- and 6-cylinder automobile engines using the same production line. The cost required to set up the production line to produce the 4-cylinder rods is $1800 and the cost required to set up the production line for the 6-cylinder rods is $3200. Manufacturing costs are $16 for each 4-cylinder connecting rod and $20 for each 6-cylinder connecting rod. The production capacities are 5800 and 7200 for 6 and 4 cylinder rods respectively. The operating budget is $100,000. The selling prices are $55 per 4-cylinder rod and $70 per 6-cylinder rod. What is the optimal number of 4 and 6 cylinder rods that should be produced by the company?
