Question 1. Consider a small busy coffee shop located at a university campus, called the Cafe Hero, which offers service from 8 am to 3 pm every weekday. Customers arrive at Cafe Hero where the interarrival times for customers are distributed with EXPO (2) minutes. After arrival, customers directly proceed to the ordering counter to buy drinks and/or food. Hero has two types of drinks in their menu: tea and coffee. In addition, they sell a cold veggie sandwich. According to historical data, 35% of customers prefer tea and 65% of customers prefer coffee. In addition to their drinks, 20% of the customers want to purchase a sandwich with their drink. According to current ordering policy, at the beginning of each day, 30 sandwiches are available at the store. There are three baristas in the ordering counter. Each barista welcomes the customer, prepares the drink, and receive payment at the register. Each customer is served by one barista during its purchase. If all baristas are busy upon arrival, customers wait in line according to FIFO rule until a barista is assigned to the customers. Baristas are assigned to customers cyclically. Service times for the order preparation process are UNIF (1,3) minutes for tea and TRIA (2, 4, 7) minutes for coffee. If a customer orders sandwich, it adds another 30 seconds to the order preparation time. If a customer wants to buy a sandwich, but if there are not any sandwiches left, that customer is considered as an unhappy customer. In Cafe Hero, a cup of tea and a cup of coffee are priced as 2 TL and 5 TL, respectively. In addition, each sandwich is sold for 12 TL. After receiving their order, customers proceed to make payments at the register, accompanied by the same barista who prepares the order. Process times for receiving the payments are distributed according to EXPO (3) minutes. After the payment, the customers leave Cafe Hero. Hero wants to improve customer service, while maximizing its revenue. Develop a simulation model to help the manager to estimate the number of unhappy customers each day and the total daily revenue. Draw an Arena flowchart module representation of the current system, and provide all important modeling information. Indicate all data modules necessary (if any) to model this system.
