Homework #2 1. Given the figure below, operation 4 represents a rework operation on parts that fail inspection upon ompletion of operation 2. How many units must the process start with in order to meet the required output of 5000 units? 1 50000 units N 3 dy = 5% dy = 5% dz = 10% = 4 de = 2% 2. Part A is produced on machine 1 and then machine 2. One unit of Part A is assembled with three units of Part B, which is produced on machine 3, in assembly station 4. Machine 1 has a scrap factor of 20%, and machine 2 has a scrap factor of 10%. The assembly process has a scrap factor of 15%. Another part, Part C, is produced on machine 5 and has a scrap estimate of 25%. Part C and the subassembly comprison of Part A and Part B are assembled at assembly station 6 into the completed product. Each day, 15,000 units of the completed product are required to meet demand. Assuming that machine 3 and assembly station 6 have scrap factors of 30% each, what are the requirements for Parts A, B, and C in order to meet the daily demand for the completed product? 3. Consider a parking lot in your campus or office complex to be 400 feet wide and 370 feet deep. How many car parking spaces with the following mix of sizes fit in this lot with 90 degree parking, including entrance/exit, circulation and handicapped requirements? 25% small-sized car (8') 50% standard-sized car (9) 25% large-sized car (10) 4. A facility is to employ 200 female and 350 male employees. How much space should be planned for the restrooms? 5.
