Step by step
Solved in 2 steps
- Explain disadvantages of using waiting line models in operations ?Drivers who come to get their licenses at the department ofmotor vehicles have their photograph taken by an automatedmachine that develops the photograph onto the license cardand laminates the complete license. The machine requires aconstant time of 4.5 minutes to develop a completed license.If drivers arrive at the machine at the mean rate of 11 perhour (Poisson distributed), determine the average length ofthe waiting line and the average waiting time.If the average time between customer arrivals is eight minutes, what is the hourly arrival rate?
- Uberya Towing Services repair vehicles that break down at an average 7.5 vehicles per day. The mechanic crew can service an average of 10 vehicles per day. The crew cost is approximately Php1406 per day. The cost associated with lost productivity from the breakdown is estimated at Php500 per vehicle per day. if an additional 2 Service crews are added, What is the Expected or Total Cost (Waiting +Service Cost)?What is queuing model in the service operations? Explain different configurations of the service system?To support National Heart Week, the Heart Association plans to install a free blood pressure testing booth in El Con Mall for the week. Previous experience indicates that, on the average, 10 persons per hour request a test. Blood pressure measurements can be made following the queuing (waiting line) model we have studied with an average service time of five minutes each. a) What is the expected average number waiting in line for the testing booth? b) What is the average amount of time that a person can expect to spend waiting in line? c) On average, how long will a person spend in the system (waiting for the testing booth and having the blood pressure test)? d) What is the probability that a person arriving will have to wait for the testing booth?
- You are in charge of a quarry that supplies sand and stone aggregates to your company’s construction sites. Empty trucks from construction sites arrive at the quarry’s huge piles of sand and stone aggregates and wait in line to enter the station, which can load either sand or aggregate. Atthe station, they are filled with material, weighed, checked out, and proceed to a construction site. Currently, nine empty trucks arrive per hour, on average. Once a truck has entered a loading station, it takes 6 minutes for it to be filled, weighed, and checked out. Concerned that trucks are spending too much time waiting and being filled, you are evaluating two alternatives to reduce the average time the trucks spend in the system. The first alternative is to add side boards to the trucks (so that more material could be loaded) and to add a helper at the loading station (so that filling time could be reduced) at a total cost of $50,000. Thearrival rate of trucks would change to six per hour, and…Suggest THREE (3) methods that an operations manager can adapt to enhance their customers' waiting experience rather than simply reducing the waiting time.Game World, a video game arcade at Tanglewood Mall, has just installed a new virtual reality battle game. It requires exactly 2.7 minutes to play. Customers arrive, on average, every 2.9 minutes (Poisson distributed) to play the game. How long will the line of customers waiting to play the game be, and how long, on average, must a customer wait?
