- An M/M/4 system has an arrival rate of 15 customers per hour. Each server has a service rate of 7 customers per hour. What is the utilization factor for this system? (Round your answer to 3 decimal place.) If all servers are kept busy, how many services will be completed per hour? (Round your answer to the nearest whole number.)RideShare offers short-term rentals of vehicles that are kept in small lots in urbanneighborhoods with plenty of potential customers. With one lot, it has eight cars. Theinterarrival time of potential demand for this lot from its base of customers is 40 minutes.The average rental period is five hours. If a customer checks availability of vehicles in thislot online and finds that they are all rented for the desired time, the customer skips rentingand finds alternative arrangements. However, because customers pay a monthly fee tosubscribe to this service, RideShare does not want customers to be disappointed too often.a. What is the offered load?b. What is the implied utilization?c. What is the capacity of the process (rentals per hour)?d. What is the probability that all eight cars are rented at the same time?e. How many customers are served every hour?f. What is the utilization of the cars?g. How many cars should it have in this lot to ensure that it serves at least 90 percent ofdemand?I have no idea, please help me! 1. Assume that the arrival rate is increased to 1 customer per minute and that the service rate is increased to 1.25 customers per minute. Compute the following operating characteristics for the new system: P0, Lq, L, Wq , W, and Pw. Does this system provide better, or poorer service compared to the original system? Discuss any differences and the reason for these differences.
- McDonalds has a drive-through window and, during peak lunch times, can handle a maximum of 85 cars per hour with one person taking orders, assembling them, and acting as cashier. The average sale per order is $12.00. A proposal has been made to add two additional workers and divide the tasks among the three. One will take orders, the second will assemble them, and the third will act as a cashier. With this system, it is estimated that 120 cars per hour can be serviced. Use productivity arguments to recommend whether or not to change the current system. Hint: Productivity = revenue/labor dollarThe Riverton Post Office has four stations for service. Customers line up in single file for service on a FIFO basis. The mean arrival rate is 40 per hour, Poisson distributed, and the mean service time per server is 4 minutes, exponentially distributed. Compute the operating characteristics for this operation. Indicate whether the operation appears to be satisfactory in terms of the following: (a) postal workers’ (servers’) idle time; (b) customer waiting time and/or the number waiting for service; and (c) the percentage of the time a customer can walk in and get served without waiting at all.Give typed full explanation In an M/D/2 system, a. the service time is exponentially distributed, b. the service time is a constant, c. the interarrival time is exponentially distributed, d. the interarrival time is a constant
- A grocery store checkout counter operates with a single server to process customertransactions. Customers arrive at the counter with an average rate of 20 customers perhour, following a Poisson distribution. The average service time per customer is 2.5minutes, following an exponential distribution. Calculate the following performancemeasures for the checkout counter:a. Calculate the utilisation factor for the grocery store checkout counter. Expressyour answer as a percentage and explain what this measure represents in thecontext of queue performance. Is the system operating at its optimal level? Whyor why not?b. Average time a customer spends in the queue (waiting time).c. Average number of customers waiting in the queue.d. Average time a customer spends in the system (waiting time + service time).e. Probability that the server is idle (not serving any customer).f. Determine the probability that there will be exactly two customers in the system(both in the queue and being served) at…What effect would decreasing arrival and service variability have on the effective capacity of asystem?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 Php1500 per day. The cost associated with lost productivity from the breakdown is estimated at Php406 per vehicle per day. What is the Expected or Total Cost (Waiting +Service Cost)? If an additional Service crew is added, which is cheaper, the existing system with one service crew, or a revised system with two service crews?
- During the recent pandemic, the seaport in Savannah Georgia, the third busiest in the United States, averaged loading or unloading 6.7 cargo ships per week. The average time to unload a ship is 1.90 days. Multiple cranes to load and unload the ship operate five days a week. Do not round intermediate calculations. How many ships are waiting to be unloaded on average using Little's Law? Round your answer up to the nearest whole number. ___ ship(s) During the pandemic, at times, demand doubled, how many ships are waiting to be unloaded on average using Little's Law? Round your answer up to the nearest whole number. ___ ship(s) If demand remains at 6.7 cargo ships per week and through better scheduling, training, and crane operations, the average time to unload a ship lowers to 1.10 days, how many ships are waiting? Round your answer up to the nearest whole number. ___ ship(s)Read the case study carefully and answer the questions at the end. Mr. Ahmed, manager of the Bara Gali Hotel, is considering how to restructure the front desk to reach an optimum level of staff efficiency and guest service. At present, the hotel has five clerks on duty, each with a separate waiting line, during peak check-in time of 3:00 p.m. to 5:00 p.m. Observation of arrivals during this period shows that an average of 90 guests arrive each hour (although there is no upward limit on the number that could arrive at any given time). It takes an average of 3 minutes for the front-desk clerk to register each guest. Mr. Ahmed is considering three plans for improving guest service by reducing the length of time that guests spend waiting in line. • The first proposal would designate one employee as a quick-service clerk for guests registering under corporate accounts, a market segment that fills about 30% of all occupied rooms. Because corporate guests are preregistered, their registration…Read the case study carefully and answer the questions at the end.
