Project Objectives ● Determine the appropriate length of the presentation ● Select two system parameters to be modified to improve the ride ● Make recommendation to ultimately improve customer throughput and maximize utilization of the ride and presentation room

Methodology ● What is Simio: It is a unique modeling tool that combines the simplicity of objects with the flexibility of processes to provide modeling capability without programming. ● Why we use Simio: - Lower cost to deliver results - Better visual experience with integrated 3 D technology

Amusement Park System 12 rows of 4 Priority Group Riders Nonpriority Group Riders Single Riders Presentation Room Ride Exit

Validation & Verification of Simulation Model Validation ● Confirmed logic flow diagram with outside experts Verification ● In the results, the maximum and average number of singles in the system was 15, proving that there were always 15 singles present in the system at once ● Single and Group entities were given different sizes and colors

Current Ride Assumptions ● The ride is open for 10 hours every day ● There are 12 rows of 4 customers for the presentation room and the ride ● There is always a group available, but not always a single rider when needed ● There is always a constant number of singles in the system ● For groups, 75% are priority and 25% are non priority, each containing either 2, 3, or 4 members

Key Performance Measures 3 Main Points of Focus: 1. Maximize Daily Customers (singles and groups) Throughput 2. Maximize Utilization of the Presentation Room 3. Maximize Utilization of the Ride

Optimizing Presentation Time In general, when the presentation is 4 minutes, the system has the best performance

Optimizing Presentation Time Improved Key Performance Measures: Presentation Time (min) Utilization of Presentation Room (%) Utilization of Rides (%) Throughput of Singles 6 (Original) 97. 55 66. 32 1, 586 4 (Modified) 95. 95 97. 97 2, 234

Sensitivity Analysis ● Factors ○ Number of Rows in the Ride ■ Add two rows to the ride (12 rows to 14 rows) ○ Time of Safety Check ■ Hire one more employee for safety check ■ Reduce safety check time in half (27 seconds to 13. 5 seconds) ● Response Variables ○ Throughput of Customers ○ Utilization of Ride ○ Utilization of Presentation Room

Sensitivity Analysis 1) 2) 3) 4) Low(-), Capacity=12 rows, Safety Check Time=27 seconds High(+) Low (-), Capacity=14 rows, Safety Check Time=27 seconds Low(-) High (+), Capacity=12 rows, Safety Check Time=13. 5 seconds High(+), Capacity=14 rows, Safety Check Time=13. 5 seconds

Performance Measure: Throughput of Single Customers ANOVA Table and Plot Source P-Value A (# of Rows) 0. 013 B (Safety Check Time) 0. 812 A*B 0. 919 Assume significance level=0. 05 Factor A (# of Rows) is significant as P-Value is ≦ 0. 05 Factor B (Safety Check Time) and interaction effect are not significant since P-Value > 0. 05

Performance Measure: Throughput of Group Customers ANOVA Table and Plot Source A (# of Rows) P-Value 0 B (Safety Check Time) 0. 196 A*B 0. 916 Assume significance level=0. 05 Factor A (# of Rows) is significant as P-Value is ≦ 0. 05 Factor B (Safety Check Time) and interaction effect are not significant since P-Value > 0. 05

Performance Measure: Utilization of Ride ANOVA Table and Plot Source P-Value A (# of Rows) 0. 034 B (Safety Check Time) 0 A*B 0. 612 Assume significance level=0. 05 Factor A (# of Rows) and Factor B (Safety Check Time) are significant as P-Value is ≦ 0. 05 Interaction effect is not significant since P-Value > 0. 05

Performance Measure: Utilization of Presentation Room ANOVA Table and Plot Source P-Value A (# of Rows) 0. 035 B (Safety Check Time) 0. 347 A*B 0. 735 Assume significance level=0. 05 Factor A (# of Rows) is significant as P-Value is ≦ 0. 05 Factor B (Safety Check Time) and interaction effect are not significant since P-Value > 0. 05

Performance Measure Summary Improved Key Performance Measures: Presentation Time (min) 12 Rows (Original) 14 Rows (Modified) Utilization of Presentation Room (%) Utilization of Rides (%) Throughput of Customers 95. 95 97. 97 2, 234 95. 94 97. 95 2, 529

Final Recommendation 1. Decrease the time of the presentation from 6 to 4 minutes. 2. Increase the number of rows in the ride from 12 to 14. Comparison by the numbers: Parameters Current Ride Modified Ride 1, 586 2, 529 Presentation Room Utilization 97. 55% 95. 94% Ride Utilization 66. 32% 97. 95% Customer Throughput

Cost Analysis Decreasing Presentation time from 6 to 4 minutes ● Cost savings of 33% per presentation Adding 2 rows to the ride ● One-time cost of adding extra 2 rows ● No structural changes needed
