This is a assignment of accounting information system that I'm not sure how to do. Please help me with that. Thank you!
HW3 Window Boxes Metal window boxes are manufactured in two process steps: stamping and assembly. Each window box is made up of three pieces: a base (one part A) and two sides (two part Bs). The parts are fabricated by a single stamping machine that requires a setup time of 120 minutes whenever switching between the two part types. Once the machine is set up, the processing time for each part A is one minute while the processing time for each part B is only 30 seconds. Currently, the stamping machine rotates its production between one batch of 360 for part A and one batch of 720 for part B. Completed parts move from the stamping machine to the assembly only after the entire batch is complete. At assembly, parts are assembled manually to form the finished product. One base (part A) and two sides (two part Bs), as well as a number of small purchased components, are required for each unit of final product. Each product requires 27 minutes of labor time to assemble. There are currently 12 workers in assembly. There is sufficient demand to sell every box the system can make. a. What is the capacity of the stamping machine? Express your answer in terms of windows per min. b. What is the capacity of the overall process? c. What batch size would you recommend for the process? (Gelato) Bruno Fruscalzo decided to set up a small production facility in Sydney to sell to local restaurants that want to offer gelato on their dessert menu. To start simple, he would offer only three flavors of gelato: fragola (strawberry), chocolato (chocolate), and bacio (chocolate with hazelnut). Demand is 10kg/hour for Fragola, 15 for chocolate, and 5 for Bacio. Bruno first produces a batch of fragola, then a batch of chocolato, then a batch of bacio and then he repeats that sequence. After producing bacio and before producing fragola, he needs 45 minutes to set up the ice cream machine; he needs 30 minutes to change to Chocolato and 10 minutes to change to Bacio. When running, his ice cream machine produces at the rate of 50 kg per hour no matter which flavor it is producing (and, of course, it can produce only one flavor at a time). a. Suppose Bruno wants to minimize the amount of each flavor produced at one time while still satisfying the demand for each of the flavors. (He can choose a different quantity for each flavor.) If we define a batch to be the quantity produced in a single run of each flavor, how many kilograms should he produce in each batch? b. Given your answer in part (a), how many kilograms of fragola should he make with each batch? SmartPhone Apfel is a German company selling smart-phones. Presently, the company is only selling a 64GB model. The marketing department recently proposed to add a 128 GB model. Preliminary data suggests that (a) the margins for the product will increase (b) the total sales will remain the same and will be split 50:50 between the two models (c) there exists a mild positive correlation in the demand between the two models. Consider the following statements: 1. The coefficient of variation of the 64GB phone will go down 2. The coefficient of variation of the 64GB phone will stay constant 3. The coefficient of variation of the 64GB phone will go up 4. It would be nice for the production and distribution process if the memory component, which is the only difference between the two models, would be inserted early in the process. 5. It would be nice for the production and distribution process if the memory component, which is the only difference between the two models, would be inserted late in the process. Which of the above statements is true? 1+4 1+5 2+4 2+5 3+4 3+5 Consider a process with two machines. Only the first machine requires set up. It takes 10 minutes to set up the machine. The first machine takes 3 minutes per unit and the current batch size is 20 units. The second machine does not have a set up. It takes 4 minutes per unit. Which machine is the bottleneck? Which of the following is an example of demand pooling? Creating a centralized warehouse that stores the safety stock of multiple retailers Serving only strawberry-banana smoothies instead if both strawberry and banana smoothies Neither of above Both of above
