3 Video 1 – Simulation-based Optimization 3 Copyright © 2013 - Jeffrey S. Smith and Simio LLC | All Rights Reserved Want to select the best allocation of 10 buffer slots. Define best using throughput - maximize B2

4 Video 1 – Simulation-based Optimization 4 Copyright © 2013 - Jeffrey S. Smith and Simio LLC | All Rights Reserved Maximize: Throughput Subject to B2 + B3 + B4 10 2 B2 4 2 B3 4 2 B4 4 B2 Basic Procedure: 1. Use OptQuest to create the initial experiment 2. Use Subset Selection to identify candidates 3. Use Select Best Scenario Using KN to identify the best

5 Video 2 – Emergency Department Model Revisited 5 Copyright © 2013 - Jeffrey S. Smith and Simio LLC | All Rights Reserved RegistrationExam Treatment Trauma Routine Moderate Severe Trauma Cost = $2000 * Exam Capacity + $2500 * Treatment Capacity + $4000 * Trauma Capacity + $4000 * Nurse Capacity + $12000 * Doctor Capacity + $250 * Total Patient Waiting Hours

6 Video 2 – Emergency Department Model Revisited (cont.) 6 Copyright © 2013 - Jeffrey S. Smith and Simio LLC | All Rights Reserved Define patient Satisfaction as the proportion of patients who spend no more than 30 minutes waiting.

7 Video 3 – Emergency Department Model Revisited (cont.) 7 Copyright © 2013 - Jeffrey S. Smith and Simio LLC | All Rights Reserved RegistrationExam Treatment Trauma Routine Moderate Severe Trauma Cost = $2000 * Exam Capacity + $2500 * Treatment Capacity + $4000 * Trauma Capacity + $4000 * Nurse Capacity + $12000 * Doctor Capacity + $250 * Total Patient Waiting Hours

8 Video 3 – Emergency Department Model Revisited (cont.) 8 Copyright © 2013 - Jeffrey S. Smith and Simio LLC | All Rights Reserved Minimize Cost Subject To: Satisfaction 0.8 Define patient Satisfaction as the proportion of patients who spend no more than 30 minutes waiting. 2 Doctors 10 2 Nurses 15 2 Exam Rooms 10 2 Treatment Rooms 10 1 Trauma Rooms 5 Doctors + Nurses 6 Cost = $2000 * Exam Capacity + $2500 * Treatment Capacity + $4000 * Trauma Capacity + $4000 * Nurse Capacity + $12000 * Doctor Capacity + $250 * Total Patient Waiting Hours

9 Video 4 - Assignment 9 Copyright © 2013 - Jeffrey S. Smith and Simio LLC | All Rights Reserved Modify the Emergency Department model by creating referenced properties for the following parameters: –Satisfaction Threshold – Was arbitrarily set to 0.5 hour (30 minutes) –Nurse Cost – Was previously set to $4000 –Exam Room Cost – Was previously set to $2000 –Wait Time Cost – Was previously set to $250/hr Create experiments to test the following configurations (note that a configuration is defined as (Satisfaction Threshold, Nurse Cost, Exam Room Cost, Wait Time Cost)) –(0.5, 4000, 2000, 250) – This is the same as the configuration done in Video 3 –(0.5, 2500, 2000, 250) –(1.0, 4000, 2000, 250) –(1.0, 5000, 2000, 100) Hint: In your experiments, use the Include in Optimization property so that the new controls are held at their specified values as the optimization runs.
