- A production line has three machines A, B, and C, with reliabilities of .99, .96, and .93, respectively. The machines are arranged so that if one breaks down, the others must shut down. Engineers are weighing two alternative designs for increasing the line’s reliability. Plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. In either case, three machines (A, B, and C) would be used with reliabilities equal to the original three.a. Which plan will provide the higher reliability?b.

The salvage value of the system is 30,000 if you sell after 1 year of use. The salvage value decreases by $5,000 each year thereafter. The maximum useful life of the machine is 4 years. Using a MARR of 20% per year, determine the ESL and the corresponding Equivalent Annual Cost of the system.

Each of the 50 steps has a defect probability of 1%. The final product produced on the assembly line is defective if any one of the 50 steps made a defect. At the end of the assembly line there are two operators independently inspecting the product. Each of them is recognizing a defective product with a 90% probability. Assuming that the product is not defective, it is moved to the shipping department. Otherwise, the product is scrapped.

Based on past history, equipment 1 is expected to break down 7 times a year, with a variance of 3, and costs $600 per breakdown. equipment 2 is expected to break down 9.2 times per year, with a variance of 2.1, and costing $245 per breakdown. 1. What is the company’s expected cost for equipment breakdowns? 2. What is the variance of the breakdown cost? Provide set up of work to compare notes.You have two design options for your new line of high-resolution monitors for Computer-Aided Design (CAD)workstations. The production run is for 110,000 units. Design option A has a .90 probability of yielding 65good monitors per 100 and a .10 probability of yielding 70good monitors per 100. This design will cost $1,000,000. Design option B has a .80 probability of yielding 65good units per 100 and a .20 probability of yielding 60good units per 100. This design will cost $1,350,000. Good or bad, each monitor will cost $75. Each good monitor will sell for $150. Bad monitors are destroyed and have no salvage value. We ignore any disposal costs in this problem. Demonstrate how decision trees can be used in order to choose the design option based on the above situation. Calculate the expected monetary value (EMV) of each option and determine which option you will propose.
