A company makes two products (A and B). Each product requires time on two machines 1 and 2. the specifications for each product are as follows Product A Product B Processing time on machine 1 (hrs/unit) Processing time on machine 2 (hrs/unit) Material and labor cost (Sh./ unit) Selling price (Sh./ unit) Maximum possible sale (units) 2 1 2 14 15 16 18 130 150 The amount of time available on machine 1 is 360 hrs and on machine 2 is 260 hrs. Using simplex method determine the number of product A and B, which should be sold in order to maximize total contribution for the company.
1. Power Notebooks, Inc. plans to manufacture a new line of notebook computers. Management is trying to decide whether to purchase the LCD screens for the computers from an outside supplier or to manufacture the screens in-house. The screens cost $100 each from the outside supplier. To set up the assembly process required to produce the screens in-house would cost $100,000. The company could then produce each screen for $75. The number of notebooks that eventually will be produced (Q) is unknown at this point. a. Set up a spreadsheet that will display the total cost of both options for any value of Q. Use trial-and-error with the spreadsheet to determine the range of production volumes for which each alternative is best. b. Use a graphical procedure to determine the break-even point for Q (i.e., the quantity at which both options yield the same cost). 2.

A company that operated 10 hours a day manufactures two products on three sequential processes. The following table summarizes the data for the problem: Which of the following is the most appropriate representation for variables x and y for the given situation? a.) x is the # of units of Product 1 to be procured; y is the # of units of Product 2 to be procured. b.) x is the # of units of Product 1 to be produced; y is the # of units of Product 2 to be produced. c.) x is the # of units of Product 1 to be stored; y is the # of units of Product 2 to be stored d.) x is the # of units of Product 1 to be delivered; y is the # of units of Product 2 to be delivered.

Create a Crow’s Foot notation ERD to support the following business operations: Create a Crowsfoot notation ERD to support the following business operations: - A friend of yours has opened Marshfield Electronics and Repairs (MER) to repair smartphones, laptops, tablets, and MP3 players. She wants you to create a database to help her run her business. When a customer brings a device to MER for repair, data must be recorded about the customer, the device, and the repair (also referred to as repair request). Completing each repair request can involve multiple services (e.g. glass replacement, battery replacement, cleaning. Some services require parts. The customer’s name, address, and a contact phone number must be recorded. For the device to be repaired, the type of device, model, and serial number are recorded (or verified if the device is already in the system). Each repair request is given a reference number, which is recorded in the system along with the date of the request, and a…

Chapter 5. (M/M/s/K Model). Leia is responsible for 8 computers in the IT offices in a small business called DataWish. Each computer runs on an average for 3 weeks and requires an average of ½ or 0.5 weeks to get reset by Leia before it can start up again. If we assign the Poisson distribution to the "arrival" of each computer for service and an exponential distribution to the actual service provided, answer the following questions: a. The arrival rate would be units per week and the service rate would be units per week. b. Calculate the following operating characteristics for the M/M/s/K system: Utilization Factor (p) % Performance Measures PO (probability that sytem is empty) L (average units in units system) La (average units waiting in queue) units W (average time in the weeks system) Wq (average time in the queue) weeks c. If we assign a cost of waiting as $500 per week per computer and $800 per week of hiring Leia, what is the Total Time Cost per week cost of servicing the…
