A Visual Basic software program, PACCS, was developed to aid NASA engineers plan, design, and operate biomass production components for Advanced Life Support Systems. PACCS integrates mathematical crop models of simulated controlled environment hydroponic production of wheat, soybean, and white potato with scheduling and analysis tools. Analysis options allow for studies on the feasibility of growing multiple crops in shared environmental zones and sensitivity of off-nominal environmental conditions on desired crop production schedules. A model-based predictive controller was included in PACCS to compensate for environmental disturbances in the production system.
