- Problem 15-31 (Algorithmic) Mid-West Publishing Company publishes college textbooks. The company operates an 800 telephone number whereby potential adopters can ask questions about forthcoming texts, request examination copies of texts, and place orders. Currently, two extension lines are used, with two representatives handling the telephone inquiries. Calls occurring when both extension lines are being used receive a busy signal; no waiting is allowed. Each representative can accommodate an average of 10 calls per hour. The arrival rate is 16 calls per hour.4. CWD Business systems maintains a successful Telecom sales department for Top up call credit in which a clerk takes orders by telephone. If the clerk is occupied on one line, incoming phone calls to the department are answered automatically by an answering machine and asked to wait. As soon as the clerk is free, the party that has waited the longest is transferred and answered first. Calls come in at a rate of about 15 per hour. The clerk is capable of taking an order in an average of 3 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. The clerk is paid $15 per hour, but because of lost goodwill and sales, CWD loses about $30 per hour of customer time spent waiting for the clerk to take an order. Part B CWD is considering adding a second clerk to take calls. The store would pay that person the same $15 per hour. Using appropriate formula for the multiple channel model, answer the following questions: a. What is the probability that no…Please solve 2 questions True or false
- Provide instead: 3 Positive and 3 negative outcomes for forecasting 3 Positive and 3 negative outcomes for queuing modelConsider the order delivery system of Heartha Hardware and Construction Supplies:- Customers (whether by bulk or retail) would line up in a counter where sales representatives will entertain them. It would take about 15 minutes before a customer will be entertained due to the number of customers being served by the sales representative and only about 4 sales representatives are on duty every day.- The sales representative will take down the customer’s order in the order slip with corresponding prices. On some cases, she will ask the person in-charge in the warehouse if the items are available. She then forwards the order slip to the cashier.- The cashier would sum-up again manually the order slip from the sales representative to check the accuracy of the footing of the totals as well as the prices indicated. This would take about 10 minutes, depending on the bulk of the order being placed.- The official receipt will be printed and will be given to the…What is Nonnegativity constraints?

- Prince Shop. owns and operates a chain of popular coffee stands that serve over 30 different coffee-based beverages. The constraint at the coffee stands is the amount of time required to fill an order, which can be considerable for the more complex beverages. Sales are often lost because customers leave after seeing a long waiting line to place an order. Careful analysis of the company's existing products has revealed that the opportunity cost of order- filling time is P34.00 per minute. The company is considering introducing a cappuccino, to be made with almond extract and double-fine sugar. The variable cost of the' standard size amaretto cappuccino would he P4 60 and new product, amarettoThe mode is used infrequently in business applications because?The average waiting time of customers over 10 replications obtained from a termination simulation model is shown below Replication / Average waiting time 1 / 3.90 2 / 1.18 3 / 4.88 4 / 4.21 5 / 1.83 6 / 3.77 7 / 1.7 8 / 2.92 9 / 2.39 10 / 2.70 Use alpha = 0.05 for following questions, if needed a) what is the minimum number of sample size required, if the error criterion is 0.75?
