ASSIGNMENT PROBLEM A: Consider the following four step process: -A-B-C-D- The following data are available for the four steps: A B D Activity time per unit (min) 0.25 0.33 0.2 0.5 Capacity per worker (units/min) 4 3 5 2 Number of workers 2 3 2 4 Suppose the steps in activity D are made easier, so the activity time per unit in step D is reduced by 50% (to 0.25 minutes per unit). If the assignment of workers to steps remains the same, by how much does the capacity of the entire process increase in units per minute? ASSIGNMENT PROBLEM B: Panini, a popular sandwich shop, offers 3 types of sandwiches: grilled vegetables, grilled chicken, and pastrami. The table below provides demand data: Grilled Vegetables Grilled Chicken Pastrami Demand per hour 25 15 10 There are up to five steps in the process of making sandwiches listed below with activity times. Suppose Panini employs 1 worker at each step. What is the highest implied utilization of this process? Step Grilled Vegetables Grilled Chicken Pastrami Cut bread .75 minutes .75 minutes .75 minutes Grill 1.4 minutes 1.4 minutes Slice meat 3 minutes Toast 2 minutes 2 minutes 2 minutes Wrap .5 minutes .5 minutes .5 minutes ASSIGNMENT PROBLEM C: (Paris Airport) Kim Opim, an enthusiastic student, is on her flight over from Philadelphia (PHL) to Paris. Kim reflects upon how her educational experiences from her operations courses could help explain the long wait time that she experienced before she could enter the departure area of Terminal A at PHL. As an airline representative explained to Kim, there are four types of travelers in Terminal A: Experienced short-distance (short-distance international travel destinations are Mexico and various islands in the Atlantic) travelers: These passengers check in online and do not speak with any agent nor do they take any time at the kiosks. Experienced long-distance travelers: These passengers spend 3 minutes with an agent. Inexperienced short-distance travelers: These passengers spend 2 minutes at a kiosk; however, they do not require the attention of an agent. - Inexperienced long-distance travelers: These passengers need to talk 5 minutes with an agent. After a passenger checks in online, or talks with an agent, or uses a kiosk, the passenger must pass through security, where they need 0.5 minutes independent of their type. From historical data, the airport is able to estimate the arrival rates of the different customer types at Terminal A of Philadelphia International: Experienced short-distance travelers: 100 per hour Experienced long-distance travelers: 80 per hour - Inexperienced short-distance travelers: 80 per hour Inexperienced long-distance travelers: 40 per hour At this terminal, there are four security check stations, six agents, and three electronic kiosks. Passengers arrive uniformly from 4 p.m. to 8 p.m., with the entire system empty prior to 4 p.m. (the "midafternoon lull") and no customers arrive after 8 p.m. All workers must stay on duty until the last passenger is entirely through the system (e.g., has passed through security). What are the levels of implied utilization at each resource? How much the process can produce in one hour
