Twо preschооlers аre sitting аt а table side by side, each stacking a different set of blocks and not talking with each other. They are engaged in:
(30 pоints) Annuаl demаnd fоr number 2 pencils аt the campus stоre is normally distributed with a mean of 1,000 and a standard deviation of 250. The store purchases the pencils for 6 cents each and sells them for 20 cents each. There is a two-month lead time from the initiation to the receipt of an order. The store accountant estimates that the cost in employee time for performing the necessary paperwork to initiate and receive an order is $20, and recommends a 22 percent annual interest rate for determining holding cost. The cost of a stock-out is the cost of lost profit plus an additional 20 cents per pencil, which represents the cost of loss of goodwill. a) (25 pts) Find the simultaneous optimal values of Q and R. b) (5 pts) What is the safety stock for this item at the optimal solution? (35 points) Suppose that one wishes to schedule vehicles from a central depot to five customer locations. The cost of making trips between each pair of locations is given in the following matrix. (Assume that the depot is location 0.) Cost matrix cij: To From 0 1 2 3 4 5 0 20 75 33 10 30 1 35 5 20 15 2 18 58 42 3 40 20 4 25 Assume that these costs correspond to distances between locations and that each vehicle is constrained to travel no more than 50 miles on each route (the 50 miles does not include the drive time to and from the depot (0)). Find the routing suggested by the savings method developed by Clarke and Wright. (25 points) Customers arrive in a local bakery with an average time between arrivals of 5 minutes. However, there is quite a lot of variability in the customers’ arrivals, as one would expect in an unscheduled system. The single bakery server requires an amount of time having the exponential distribution with a mean of 4.5 minutes to serve customers (in the order in which they arrive). No customers leave without service. Consider this as an M/M/1 queue. a) (10 pts) Calculate the average utilization of the bakery server. b) (5 pts) Calculate how long customers spend on average to complete their transactions at the bakery (time in queue plus service time). c)(5 pts) Calculate how long customers spend on average in the queue d)(5 pts) How many customers are in the bakery on average? (10 points) Please assign the inventory control models we have learned into their correct category (only one). Inventory control models: (a) The basic EOQ model (b) The EOQ with a finite production rate (c) EOQ models for production planning (d) Newsvendor model (e) (Q, R) model with service levels (f) (Q, R) model with stock-out cost (g) (Q, R) model periodic review with (s, S) policies (h) Resource-constrained multiple product systems (i) Quantity discounts (j) ABC analysis (item A) Category: Known demand, continuous review Know demand, periodic review Uncertain demand, continuous review Uncertain demand, periodic review
