A Multiple Attribute Decision Analysis of Manned Airlock Systems

Abstract

This study is a multiple attribute decision analysis involving five manned airlock alternatives. The five alternatives are the present shuttle airlock system augmented with additional consumable gas tanks four variations of the Crewlock, a new airlock design concept proposed by Mr. William Haynes of the Aerospace Corporation. The purpose was to identify which airlock system can best support both the normal shuttle mission extravehicular activity (EVA) and the shuttle's EVA requirements during construction of the space station. Only physical characteristics and performance parameters are included in the analysis. Cost factors are not addressed. The analytic hierarchy process (AHP) was used to structure the problem and helped identify and rate ten airlock attributes, safety, reliability, weight, size, volume, transit time, depressurization time, repressurization time, expendable gas usage, and number of EVA periods per mission. Compromise programming was used to identify the airlock system closest to the 'ideal solution' using the AHP-derived weights. Keywords: Theses; Void fillers; Decision making; Operations research.
