B I Rachowitz: 1182. Designing to Cost (DTC/LCC). 1977.



In today’s highly cost conscious atmosphere, it is extremely important for all sectors of the Aerospace Industry to develop methods which will allow us to understand the factors that drive costs in all phases of a program’s life cycle. The development and implementation of these methods is extremely important if we are to control program costs. At Grumman we have and are continuing to develop Design-To-Cost/Life Cycle Cost Methodology for establishing and designing to Design-to-Cost/Life Cycle Cost goals.
This paper will give you an overview of Grumman’s Design-to-Cost/Life Cycle Cost Methodology. It will review some of the design sensitive relationships that Grumman is continuing to develop for use in conceptual and preliminary design, including relationships for all three phases of a program (RDT&E, Production, O&S). We at Grumman feel the design engineer is the key in the DTC/LCC process and therefore we have developed a series of tools to permit the design engineer to trade cost and performance, rapidly, during the design process, these tools will also be discussed. A review of some current trade studies conducted on various programs will be presented. Also I shall discuss the Design-To-Cost organization at Grumman and its function/responsibilities, practical ,examples of applications of tools and methods and training involved in making it a success.
