Summary Introduction
To determine: The number of sales people to be hired.
Introduction: The mathematical study which analyses the causes of delay in the waiting line is known as queuing theory. The theory examines all components in the waiting line such as arrival process, service process, and number of servers, system and customers.

Question #4: On average, how many cars do you expect to have in the drive-thru line? (Include those waiting to place orders and those waiting for food.)
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.
True or False

b) the probability of 4 customers in the system?
c) the average time a customer spends waiting in line (in minutes)?

- Question 4: As quote by Mahatma Gandhi on Customer Service “A customer is the most important visitor on our premises. He is not dependent on us. We are dependent on him. He is not an interruption in our work – he is the purpose of it. We are not doing him a favor by serving him. He is doing us a favor by giving us the opportunity to serve him”. What those words above meaning in your opinion?arrow_forward1 Infinite source. One of the features of a new machine shop will be a well-stocked tool crib. The manager of the shop must decide on the number of attendants needed to staff the crib. Attendants willreceive $9 per hour in salary and fringe benefits. Mechanics’ time will be worth $30 per hour, whichincludes salary and fringe benefits plus lost work time caused by waiting for parts. Based on previousexperience, the manager estimates requests for parts will average 18 per hour with a service capacity of 20 requests per hour per attendant. How many attendants should be on duty if the manager iswilling to assume that arrival and service rates will be Poisson-distributed? (Assume the number ofmechanics is very large, so an infinite-source model is appropriate.)arrow_forwardQuestion The new accounts loan officer of the Millennium Commercial Bank interviews all customers for new accounts. The customers desiring to open new accounts arrive at the rate of 4 per hour, according to a Poisson distribution, and the accounts officer spends an average of 12 minutes with each customer, setting up a new account. Required A. Determine the operating characteristics (P0, L, Lq, W, Wq and Pw) for this system. B. Add an additional accounts officer to the system described in this problem so that it is now a multiple-server queuing system with two channels and determine the operating characteristics required in part A.arrow_forward

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? Identify the type of integer programming framework (Total Integer, Mixed Integer or Binary) that applies to this problem, develop the appropriate formulation (decision variables, objective function and constraints)arrow_forwardQuestion in the picturearrow_forward

How would this change the average number of cars in the drive thru-line?arrow_forwardQuestion 5 Strohrmann, a large-scale bakery in Pennsylvania, is laying out a new production process for their packaged bread, which they sell to several grocery chains. It takes 12 minutes to bake the bread. How large an oven is required so that the company is able to produce 4,000 units of bread per hour (give your answer in terms of the number of units that can be baked simultaneously)?arrow_forwardName the three parts of a typical queuing system.arrow_forward
