Problems Encountered
Lack of information from the company. Time study
was substituted with MOST Work
Measurement. Videos were not delivered.
20
Future Work

• Final Report and Presentation
• Arena5.0 Simulation Results
• Recommendations

21
Conclusions

• Even though some of the data was available later
  than expected, the project is still scheduled to
  be completed on time.
• Additional factors such as production forecast,
  scrap rates, delivery times, and machine
  characteristics will be added to the final model.
