  2. Agenda • Problem Statement • Accomplishments For The Transport System • Design History • Final Design • Summary Of Test Results • Recommendations • Accomplishments For The Layout • Design History • Final Design & Test Results • Recommendations • Reflection On The D-R/RIT Partnership • Reflection On Our Code Of Ethics

  3. Problem Statement Design a flexible material handling system that is easy to useand incorporates the safest design elementswithin cost and functionality constraints. This design fully supports the new process layout in Dresser-Rand’s strategic project to increase capacity for the MOS compressor projected sales. 6-throw MOS Compressor New Shop Floor

  4. Transport System Design History • Design Considerations • Long Beam Caster System • Short Frame Caster System (Yellow Frame) • Air Bearing Technology • Free Support System • Fixed Support System • Modified Support System

  5. Design Considerations Movement Propulsion

  6. Long Beam Caster System • Assumed entire compressor assembly would be loaded, including cylinders • Assumed massive CG changes while loaded • Large structural members necessary

  7. Short Frame Caster System • Yellow Frame Design • Versatile – to account for multiple product families • Modular – to account for multiple product sizes • Could not be used at test station • Was prototyped • Many design flaws surrounding caster system

  8. Air Bearing Technology • Unidirectional • Nearly frictionless • Reduces horizontal force required to 1lb per 1000lbs • Air supply is common in industrial setting • Requires flat, smooth floor surfaces

  9. Free Support System • Based on the short frame system • Adapted for air pallet use • Legs fixed to support beam • Concerns regarding clearance between floor and legs during movement

  10. Fixed Support System • Vertical “legs” of the Free system are now fixtures placed at each station • Eliminates floor clearance concerns while moving from station to station • Simplifies manufacturing • Easily integrated into testing and shipping

  11. Removable Support System • Conceptual design • Method of manufacture and dimensions undetermined • Removable fixture attaches to beam and acts like a jack stand • Overcomes flaws that were revealed during the 3P event • Stress analysis not completed • results should be comparable to the free system results

  12. Removable Support Qualities • Pros • No more fixtures • Resolves ergonomic issues discovered during the 3P event • Lowers move prep time – no longer need to configure fixtures from station to station • Bolt on legs removable for test and shipping • Cons • Requires the floor to be leveled

  13. Test Results

  14. Recommendations • Modify testing station to incorporate free-system design • Possible lifting/attachment to test bed • Determine lifting/loading method • Need 3-axis positioning without a crane • Modified Grey Portable Lifting system for vertical lifting • Back truck under lifted compressor • Air bearings under truck bed • Driver positioning

  15. Layout Design History • Took dimensions of required equipment and space for each station in the assembly, test, and paint process in the current state • Created factors of varying importance • Designed 4 different layouts – 2 straight-line, 2 U-shaped – in the new shop floor • Conducted a 3P event on a U-shaped layout using cardboard to check theoretical values against actual feedback from operators and line side managers

  16. Final design Top Level Assembly Level Flow

  17. Recommendations • Re-evaluate test bay requirements for sizing and safety – retractable blast walls • Add in and test inventory flow and information flow • Understand exact requirements and locations for energy/power/air sources • Full dimensioning of layout • Computer simulation of process flow • Continuous evaluation and improvement • 5S taping and marking to indicate specific areas, i.e. operator walking zone inside cell, in-process kanban, visitor aisle way • Identify and allocate future expansion area

  18. Reflection on the DR/RIT Partnership • Overall, very successful learning experience • Design process • Iterative in nature – lots of ‘back to the drawing board’ moments • Conceptualization and the funnel of idea development • Understanding fluctuating customer needs • Efficiency of communication • Recommend a “consulting” contract be completed at the start • To better establish the needs of Dresser Rand • So the team can better prioritize efforts • Recommend creating a communications protocol to prevent delay in work as the team awaits feedback

  19. Reflection On Our Code Of Ethics 3 out of 11 components were not followed satisfactorily
