Value Engineering Dresser Rand Compressor Case SENIOR DESIGN PROJECT P 08455 Stephen Papa (IE- Project Manager), Chris Bulawa (ME), John Foley (ME), Eric Hodecker (ME) and John Roylance-(IE)

Value Engineering in a Manufacturing Facility 2 Objective: Design and build a safe compressor final internal assembly stand for the Olean Manufacturing Facility.

Identify Customer Needs 3 Step 1: Gather Raw Data From Customers Interviews Dresser Rand Site Visits Step 2: Interpret Raw Data in Terms of Customer Needs Customer Statement -> Interpreted Needs

Step 3: Project Requirements 4 Key Needs: Adjust to different sized compressors. [Length (35”-86”) and Diameter 21”-43”)] Organize the Needs into a Hierarchy: Need 1: Need 2: Be able to support up to 30, 000 lbs for a week. Need 3: Need 4: Need 5: Support different sized Heads Work bench to support assembly tools Need 6: Need 7: The holding technique and hardware needs to be safe. The holding technique and hardware needs to avoid damage. The holding technique and hardware needs to support compressor case functions. The holding technique and hardware needs to be adjustable. The holding technique and hardware needs to be quick. The lifting technique and hardware needs to be cost effective. The holding technique needs to be standardized. Organize the Needs into a Hierarchy:

5 Step 4. Establish the Relative Importance of the Needs

6 Step 3: House of Quality:
