[A computer-aided design assessment system for recovery life support technology options]

Area of Science:

• Space engineering
• Decision science
• Life support systems

Context:

• Manned space stations require robust Environmental Control and Life Support Systems (ECLSS).
• Assessing and selecting technologies for ECLSS is complex due to evolving mission requirements and crew needs.
• Existing decision-making processes may lack the advanced computational support needed for optimal system design.

Purpose:

• To design and implement a computer-aided decision support system (CDSS) for ECLSS.
• To develop an advanced multiobjective decision methodology and a hierarchic assessment index model for recovery life support systems.
• To provide recommendations for candidate technology selection and development within ECLSS.

Summary:

• The developed CDSS integrates a database of technology options, crew metabolic loads, and mission variables.
• It employs advanced algorithms to generate product criteria for technology assessment.
• The system's structure includes a database, methodology base, and model base, managed effectively, with a user-friendly control system for enhanced man-computer interaction.

Impact:

• Facilitates informed decision-making in the design and assessment of space station ECLSS.
• Enhances the selection and development process for critical life support technologies.
• Improves the efficiency and effectiveness of ECLSS design through advanced computational support and user interaction.
