Optimizing Flexible Complex Systems with Coupled and Co-Evolving Subsystems under Operational Uncertainties
Koki Ho, Masafumi Isaji, Malav Patel +1
The paper develops a novel design optimization framework and associated computational techniques for staged deployment optimization of complex systems under operational uncertainti…
Optimisation of Categorical Choices in Exploration Mission Concepts of Operations Using Column Generation Method
Nicholas Gollins, Masafumi Isaji, Koki Ho
Space missions, particularly complex, large-scale exploration campaigns, can often involve many discrete decisions or events in their concepts of operations. Whilst a variety of me…
Generalizing Space Logistics Network Optimization with Integrated Machine Learning and Mathematical Programming
Koki Ho, Yuri Shimane, Masafumi Isaji
Recent growing complexity in space missions has led to an active research field of space logistics and mission design. This research field leverages the key ideas and methods used…
Multidisciplinary Design Optimization Approach to Integrated Space Mission Planning and Spacecraft Design
Masafumi Isaji, Yuji Takubo, Koki Ho
