In today?s business climate, aerospace companiesare more than ever in need of rational methods andtechniques that provide insights as to the beststrategies which may be pursued for increasedprofitability and risk mitigation. However, the use of subjective, anecdotal decision-making...

This dissertation describes the development of a game-based methodology that facilitates the exploration and selection of research and development (R&D) projects under uncertain competitive scenarios. The proposed method provides an approach that analyzes competitor positioning and formulates...

The need for a comprehensive framework for the analysis of military system effectiveness is presented. Changes in the world’s economy and its effect on decision making is discussed, as well as the three primary ways decision makers use information: resource allocation, requirements definition,...

Several approaches to probabilistic design have been proposed in the past. Only few acknowledged the paradigm shift from performance based design to design for cost. The incorporation of economics in the design process, however, makes a probabilistic approach to design necessary, due to the...

The objective of this paper is to discuss a few challenges foreseeable for future aircraft engine designs and briefly survey ongoing research that addresses these challenges. Emphasis is placed on methods for selecting commercial engine architectures. Four fundamental needs are identified and...

This paper presents an exploratory study for identification and quantification of the economic benefits or implications associated with wing cost variations. A hierarchical cost model structure is used to determine life cycle effects of design and manufacturing alternatives for the major...

There is a significant investment being made within the design community developing tools identifying metrics for all considerable recyclability, etc.) of design in an attempt to bring these issues into the early stages of a design process. Additionally, within the aerospace community there has...

An evolved version of the Technology Identification, Evaluation, and Selection (TIES) method is presented that provides techniques for quantifying technological uncertainty associated with immature technologies. Uncertainty in this context implies forecasting. Forecasting the impact of immature...

The design of complex systems, such as commercial aircraft, has drastically changed since the middle 1970's. Budgetary and airline requirements have forced many aerospace companies to reduce the amount of time and monetary investments in future revolutionary concepts and design methods. The...

The growth of international markets as well as business partnerships between U.S. and Asian-based firms has lead to an increased interest in an economically viable business jet capable of supersonic cruise and trans-Pacific range with one stop over (or non-stop trans-Atlantic range) 1 . Such an...
