  3. 3. Background<br />What does Gulfstream Aerospace do?<br />Gulfstream Aerospace Corporation is a global manufacturer of business jet aircraft.<br />“The Gulfstream product line offers an exceptional combination of price, performance, and value-added customer preferences in each segment of the mid-cabin to ultra-large-cabin business jet market.”<br />Gulfstream employs more than 9700 people at seven major locations: Savannah, GA; Appleton, WI; Dallas, TX; Long Beach, CA; Brunswick, GA; London, UK; and Mexicali, Mexico.<br />34 governments operate Gulfstream jets and 22 countries, incl. the US, use Gulfstream aircraft to transport their head-of-state.<br />Gulfstream aircraft have also been reconfigured and equipped to be involved in missions as diverse as maritime and aerial reconnaissance, medical evacuation, and pilot and astronaut training.<br />3<br />
  4. 4. History<br />1958 - First appearance as the G-I (a turboprop driven) series of Grumman Aircraft Engineering Co. <br />1966 – At the beginning of GII series production, military focused Grumman separated the business aircraft division and relocated in Savannah, GA.<br />1977 – The Gulfstream Line and the Savannah plant were sold to American Jet Industries, which was headed by an aviation entrepreneur Allen Paulson. Paulson renamed the company Gulfstream American.<br />1979 – GIII made its first flight. It also became the first business jet to fly over both poles.<br />1982 – The company renamed as Gulfstream Aerospace Corp.<br />1983 – The company went public by offering 8.8 Million shares of its stock.<br />4<br />
  5. 5. History<br />1985 – Chrysler acquired Gulfstream Aerospace. Gulfstream entered the Fortune 500 list from the 417th place.<br />1989 – Paulson and Forstmann Little & Co. teamed up and bought Gulfstream back from Chrysler for $825 Million.<br />1994 – Gulfstream signed its first 5-year contract with NetJets.<br />1997 – With the expansion of Savannah plant in ‘96, Gulfstream began manufacturing two different aircraft simultaneously, the GIV & GV.<br />1999 – General Dynamics acquired Gulfstream for $5 Billion.<br />2002 – Gulfstream renamed its products with Arabic numerals instead of Roman ones (i.e. GII to G200, GIV to G400).<br />2006 – Gulfstream started to replace its product line (i.e. G100 to G150, G400 to G450).<br />5<br />

  73. 73. Production<br />Challenges:<br />Producing two or more different models at the same time.<br />Lowering the costs while increasing the quality and safety of the product. <br />Due to rapid changing market, adaptation should be as fast as possible.<br />Performing more “final phase manufacturing” while utilizing less capacity.<br />Constraints:<br />The “final phase manufacturing” capacity is limited.<br />Each aircraft is different.<br />Different engineering configurations<br />Personnel skills<br />Inventory outfitting and manufacturing devices cost.<br />The cycle time was over 30 weeks, not a competitive advantage at all.<br />Aircraft is a difficult product to test, maintain, and service.<br />So, how did Gulfstream Aerospace handle these challenges and overcome aircraft production issues?<br />35<br />
  74. 74. Production<br />The Answer: “Reducing variability while keeping diversity high.”<br />Concurrent manufacturing and the Rollback program triggered Lean Production and Continuous Improvement among assembly level activities.<br />“Within the value-stream of manufacturing, you have the necessity, if not the obligation, of maximizing the distribution of resources and tasks (Lombardo, 2004).”<br />80% of the customers are looking for the same, standard configurations. <br />Reduction of cycle-times<br />Standardized engineering methods (drawings, software, personnel skill, etc.)<br />Standardized wiring, furniture, and cockpit solutions<br />Standard requirements are, thereby, rolled back to initial phase manufacturing.<br />12-week outfitting cycle went down to four weeks.<br />Gulfstream also value-stream maps its supplier activities and tries to find solutions to reduce costs.<br />What else does Gulfstream do for quality improvement?<br />36<br />
  75. 75. Production<br />The Answer: “Total Quality Management (TQM) is a must.”<br />Since the number of industrial engineers are limited to identify every single waste, employees are empowered by suggesting ideas to the “parking lot” idea pool.<br />The parking lot is the pool of ideas that every employee from every level might suggest anything to improve lean manufacturing process by eliminating waste.<br />To avoid excessive debris, the ideas are filtered according to following criteria:<br />The idea should support 5-year lean vision.<br />There must be a positive business case for it.<br />There must be sufficient resources and budget for the idea.<br />Clear definition of objectives with responsibility and schedule.<br />Every ‘suitable’ idea are analyzed regarding its cost vs. benefit ratio<br />In essence, Gulfstream focuses on Lean and 6-Sigma concepts to eliminate waste while improving overall quality and decreasing costs. <br />Continuous Improvement is one of the key components of the process.<br />37<br />
  76. 76. Production<br />G450 & G550 Examples:<br />Both aircraft has its final phase manufacturing at the Savannah plant.<br />G45 & G550 are visually identical.<br />Required pilot ratings are the same.<br />They share most of the electrical infrastructure (cockpit displays, pressurization system, nose landing gear, oxygen & fire extinguishing systems, etc.)<br />Since common systems require identical parts, the inventory variety is minimal.<br />Reduction in various aspects:<br />Skilled personnel<br />Testing<br />Maintenance costs<br />Support difficulty<br />Training costs<br />Overall Inventory<br />38<br />
  77. 77. Production<br />Innovative G650<br />Parts count has been slashed by 50%, compared to previous large cabin aircraft.<br />The large aluminum components assemblies have precisely positioned with pre-drilled mounting holes for fasteners.<br />Assembly time slashed because no custom fitting, machining or filing is needed to build the primary airframe structure.<br />However, G650 is a clean sheet product line for Gulfstream. <br />There are various aspects that might increase cycle time:<br />All fly-by-Wire aircraft<br />New certification<br />New pilot rating requirements<br />Additional test aircraft<br />200+ orders today, valuing approximately $13 Billion.<br />39<br />

  79. 79. Story of a GV<br />High-performance Instrumented Airborne Platform for Environmental Research (HIAPER)<br />An advanced airborne research platform built and modified to serve the National Science Foundation's environmental research needs for the next several decades.<br />One of the Special Missions of Gulfstream Aerospace<br />In December 2001, Gulfstream was awarded the contract of manufacturing a special modified GV which will be used for testing scientific payloads at such high altitudes that will enable scientists to conduct important atmospheric studies in and near the Tropopause.<br />Modifications were made by Gulfstream and Lockheed Martin at Savannah, GA plant & Greenville, SC center, respectively. <br />While a regular GV costs approximately $56 million, the HIAPER GV cost around $80 million.<br />Production of the basic green aircraft was completed in 2002.<br />Lockheed Martin kept the aircraft for testing and modification until June 2004.<br />The final product delivered to the University Corporation for Atmospheric Research in 2005.<br />41<br />

  81. 81. Conclusion<br />Assemble-to-Order approach<br />80% of the orders are standard configurations.<br />The interior and additional Cockpit solutions are implemented on demand.<br />Initial manufacturing phases are not interrupted by any customization demand.<br />The customization occurs is during final manufacturing phases.<br />Various Lean Manufacturing and 6-Sigma approaches<br />Multiple Test aircraft, testing different systems concurrently.<br />Multiple aircraft production simultaneously.<br />Robust supplier & customer relations benefit both quality and inventory flow.<br />Initial Manufacturing phases are done in several sites around the globe.<br />Final Manufacturing phases are done in several sites around the globe as well (Savannah & Israel plants).<br />Even though Gulfstream strives for reducing variability in product line, the company competes at several markets.<br />Mid, Large, and Ultra-Large cabin portfolio<br />43<br />
