The contribution of this paper to the space transportation system field is to select promising Reusable Launch Vehicle (RLV) concepts by using a formal evaluation procedure. The vehicle system is divided into design features. Every design feature can have alternative characteristics. All combinations of design features and characteristics are compared pairwise with each other. The innovation an...

This article aims to provide the reader with a clearer understanding of similarities and divergences that exist between grey fuzzy theory. The notion is considerably more established grey, however, in recent years theory has garnered traction become noticeable wider audiences. Both can be seen as being proponents uncertainty modelling, within their repertoires there are indeed facets similar na...

In the analytic hierarchy process (AHP), the consistency of pairwise comparison is measured by the consistency index (CI) value of pairwise comparison matrices. The CI value is defined by the size and the principal eigenvalue of comparison matrix, and the larger the CI value is, the less consistent pairwise comparison is. In this paper, we propose the estimation method of consistency intervals,...

In many real-world applications, designs can only be evaluated pairwise, relative to each other. Nevertheless, in the simulation literature, almost all ranking and selection procedures are developed based on individual performances of design. This research considers statistical problem when design performance simulated pairwise. We formulate this new using optimal computing budget allocation ap...
