At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.
Adele Weiss manages the campus flower shop. Flowers must be ordered three days in advance from her supplier in Mexico. Although Valentine’s Day is fast approaching, sales are almost entirely last-minute, impulse purchases. Advance sales are so small that Weiss has no way to estimate the probability of low (25 dozen), medium (60 dozen), or high (130 dozen) demand for red roses on the big day. She buys roses for $15 per dozen and sells them for $40 per dozen. Construct a payoff table. Which decision is indicated by each of the following decision criteria?a. Maximinb. Maximaxc. Laplaced.

Terex Corporation is a global manufacturer of aerial work platforms and materials processing machinery. They design, build and support products such as large lifting equipment used in construction. The company makes most pieces to order and customizes them to meet customers’ unique preferences.Terex maintained a manual system for yard management at their transfer centre in Washington that is always full of lifting equipment, which generated excessive costs for what should have been a relatively simple process of locating customers’ units to prepare them for delivery. A wallboard and sticker system was a low-tech solution for identifying equipment items in the yard at Terex. While inexpensive in itself, the solution cost around six minutes every time an employee had to locate a unit in the yard. It also required a considerable number of hours to be spent each month taking physical inventories. After a successful pilot, the company approved a new solution, replacing stickers, yard maps,…

Prybloxx primarily uses one courier company, AJAX Couriers, for all their deliveries. In some circumstances, where AJAX is too busy and does not have capacity to fulfil deliveries or they do not cover certain areas, only then will Prybloxx make use of a different courier company. Prybloxx has recently had a significant influx of customer complaints regarding goods that have not been delivered, delivered long after the agreed delivery time or damaged once they arrive at the customer. Prybloxx is aware of the effect that this could have on demand for their product, customer goodwill and are now investigating insourcing the delivery of their product to customers. Prybloxx has noted that they have two alternatives in insourcing this department – they can either purchase a local courier company that is considered a going concern or they can purchase all of the required assets and set up such a department themselves. Mr. Pranoto (production manager) has requested that you prepare a report…
Mr Smith is working as the director of credit collection department at SISHGC Building Supplies Limited. The credit collection department recently shifted from the legacy system to a new system that was installed four months ago. Mr Smith is not happy with this newly installed system. His complaint is that the data flow from the billing and account receivable departments is not occurring in the manner originally requested. Further, the updates to the database files are not occurring as frequently as he had envisioned. Thus, the hope that the new system would provide more current and timely information has not materialised. Mr Smith claims that the systems analysts spent three days interviewing him and other workers in his department. During that time, he and the other workers thought they had clearly conveyed their needs. At this stage, Mr Smith feels as if their needs were ignored, and their time was wasted. Required: Identify the issues in the system design process. How can these…

A convenience store uses the fixed-period inventory control system (FPS) to manage its inventory of distilled water bottles. This system relies on the following information. (a)Using EOQ (rounded up), what is the time interval between reviews T in operating days? Note that after having the rounded-up EOQ, you should not round up values at intermediate steps; and, you should round T up only after the last calculation. (For example: enter 10 for 10 days.) (b) What is the current inventory position (IP) in bottles? (For example: enter 70 for 70 bottles) (c)Without safety stock, what is the replenishment level without safety stock M(AD) in bottles? Note that the question does not ask for M(ST). (For example: enter 70 for 70 bottles) (d)If today is the review day and without safety stock, what is the order quantity in bottles given M(AD)? (For example: enter 70 for 70 bottles)
