The Seaboard Shipping Company has a warehouse terminal
in Spartanburg, South Carolina. The capacity of each termi-nal dock is three trucks. As trucks enter the terminal, the dri-vers receive numbers, and when one of the three dock spaces
becomes available, the truck with the lowest number entersthe vacant dock. Truck arrivals are Poisson distributed, and
the unloading and loading times (service times) are expo-nentially distributed. The average arrival rate at the terminal
is five trucks per hour, and the average service rate per dockis two trucks per hour (30 minutes per truck).a. Compute L, Lq, W, and Wq.
b. The management of the shipping company is consider-ing adding extra employees and equipment to improve
the average service time per terminal dock to 25 min-utes per truck. It would cost the company $18,000 per
year to achieve this improved service. Managementestimates that it will increase its profit by $750 per yearfor each minute it is able to reduce a truck’s waitingtime.…

- Netflix is a DVD movie rental company. They stock 50 DVDs of a recent blockbuster movie available for rental. Their rental fee is $4 per DVD per day. The inter-arrival time between rental requests for this movie is 2.5 hours, on average, with a standard deviation of 2.5 hours. Demand is steady throughout a 24-hour day (there is no evidence of other arrival patterns). Assume that if all copies of the DVD are rented, then customers are willing to wait for the next one to become available. Also, assume shipping is instantaneous (the shipping time is zero days). A DVD is rented, on average, for 5 days with a standard deviation of 3 days. What is the average number of unrented DVDs in Netflix’s warehouse?

On average, 90 companies tip their trucks each day at the landfill with a standard deviation of 30. There is time only for 110 deliveries in any combination of companies and individuals throughout the course of an eight-hour day. Company dump trucks enter through Gate A and individuals enter through Gate B. Individual demand is plentiful – often there are individuals turned away due to lack of capacity. It costs the landfill $30 to process a company dump truck and $15 to process an individual load. What is the expected profit for one day if the landfill allocates the optimal quantity of capacity to company trucks and individuals fill up the remainder of the сараcity? -arrow_forward

- TRUE OR FALSE 1. To manage demand effectively, firms need to understand demand patterns and drivers by market segment. This would enable them to use marketing strategies and reshape those patterns. 2. Not all queuing systems are organized on a 'first-come, first-served basis. 3.
