Semi-Analytical Multidimensional Algorithm for Aircraft Design Optimisation: Student Design Build Fly (DBF) Competition

2002/2003 AIAA Foundation Cessna/ONR Student Design Build Fly Competition

Design competition through multidimensional auctions

This article studies design competition in government procurement by developing a model of two-dimensional auctions, wherejirms bid on both price and quality, and bids are evaluated by a scoring rule designed by a buyer. Three auction schemes-first score, second score, and second preferred offer-are introduced and related to actualpractices. If the buyer can commit to a scoring rule in his best...

Analytical Target Cascading in Aircraft Design

Analytical Target Cascading (ATC) is a product development tool that computes component design specifications such that the final system design is consistent and meets design targets. ATC is useful for complex product design that must be approached by decomposition, and facilitates concurrent design activities. While ATC has been applied successfully to automotive design, this article introduce...

Comparative analysis of design/build and design/bid/build project delivery systems in Lebanon

Design/bid/build and design/build are two principal project delivery systems used worldwide. The performance of each project may differ with the type of procurement system used. This study has two aims: firstly, to assess and compare the performance of design/bid/build and design/build projects in Lebanon; secondly, to compare the results with the performance of equivalent systems in the Far Ea...

Vizcraft: a Multidimensional Visualization Tool for Aircraft Connguration Design

We describe a visualization tool to aid aircraft designers during the conceptual design stage. We define the design for an aircraft by a vector of 10–30 parameters. The goal is to find a vector that minimizes an objective function while meeting a series of constraints. VizCraft integrates the simulation code that evaluates the design with visualizations for analyzing the design individually or ...
