Q2 (10 points) Anyan and company decided to change their business again and to focus on delivering a major UK classic: fish and chips. Due to COVID, all orders are by phone, and the process starts with Elena and Dorothee receiving the orders and processing payments. After the order is placed and the payment processed, Anyan starts cooking the fish. At the same time, Bob starts peeling and cutting the potatoes, and after Bob is done Charlotte fries them. Once Anyan and Charlotte finish their task, Ignacio takes the fish and chips, box them, and prepares them for delivery. The time for placing an order and accepting payment is 2 minutes (both Elena and Dorothee take exactly the same time to perform their activity). The time for cooking the fish is 5 minutes; peeling and cutting the potatoes takes 4 minutes, and frying the potatoes takes 2 minutes. Finally, boxing and preparing for delivery takes 1 minute. (a) Draw the process diagram for the above process. (2 points) (b) What is the process capacity and what is (are) the bottleneck(s) of the process? (2 points) (c) What is the cycle time of the process? (2 points) (d) What is the theoretical flow time of the process? (2 points) (e) Suppose that Anyan and company decide to stop receiving orders by phone and switch to a fully online system (e.g., Dashdoor or Uber Eats) that notifies them directly when an order arrives (i.e., Anyan and Bob are directly notified when to start processing an order). As a result, Dorothee and Elena must be re-located. Assuming that they can perform any task (in parallel) and that the time it takes them to do so is the same as for the other workers, where should we place them to improve the efficiency of the process? Explain and draw the resulting process diagram. (2 points)
