To increase crew efficiency during a long duration space mission, we have developed a Sequence Dependent Structured Matrix (SDSM) which enables designers to quickly derive the shortest paths astronauts (mission specialists) need to perform their daily tasks. This research aims to develop a new efficient tool by combining two or more DSM interpretations which help increase the ability of proper decision makings for complex situations as space travel. The results of this work have been used for arranging crew quarters in the spacecraft suited for Mars mission. In the same approach, we have been able to generalize the concept and construct different specific types of DSM; such as, Astronauts’ Privacy DSM to effectively manage constraints imposed by the harsh space environment. With proper data processing and with help of PSM32 software we have been able to successfully study different clusters and partition the most prominent of which is explained.
