1. Objectives Learn how to define Referenced Properties Use Controls to define multiple scenarios in experiment Evaluate different configurations of a Subway restaurant Perform comparisons using side-by-side SMORE plots

2. System Description and Data Arrival rate: 32 customers/hour Service times are all triangularly distributed with the following parameters (Minutes): Bread & Meat: (1, 1.5, 2) Oven: (0.5, 1, 1.5) Veggies: (1, 1.5, 2) Cashier: (0.5, 1, 1.5) Drink: (0.5, 1, 1.5) 70% of the customers want their sandwich toasted and 30% get cold subs The current operating policy requires that FIFO (First In First Out) must be maintained throughout the system, i.e., cold sandwiches should also wait in the queue for the oven (if there is one). Customers balk if there are 6 people in the system Bread & Meat Oven Veggies Cashier Drink Exit Enter

3. Performance Measures Evaluate the performance of the system during lunch rush Perform analysis to answer the following two questions:  Where to add two additional “resources” to reduce lost sales (balks)?  What is the best operating policy given the new system configuration (“Passing” or the current “No passing” policy)? Performance measures  Server utilizations  Average Time In System (TIS) for all customers  Expected Number in System (NIS)  Percentage of customers that balk  Average TIS per customer type Bread & Meat Oven Veggies Cashier Drink Exit Enter

4. Referenced Properties Specify the value for an object property Define experiment scenarios if set to appear as a control
