This selection includes delivered systems, applied research, validated prototypes, and platforms under development. Each entry explains the problem, my role, what was created, the available evidence, and its current status.
I developed and computationally validated a mixed-integer method that plans aircraft utilization and preventive maintenance together for instances representing about 1,500 assets. Tested cases reached verified optimal solutions in under seven minutes; the work remains a research implementation, not an operational deployment.
A complete 2009 system design for material requirements planning in manufacturing plants, covering operational workflows, MRP calculation logic, data structures, user interactions, controls, and reporting. The verified outcome is the design artifact itself; later implementation and commercial results remain unconfirmed.
A solver-independent planning engine that integrates age-based maintenance with permutation flow-shop scheduling. Three formulations—deterministic, fuzzy bi-objective, and stochastic—balance delivery tardiness and maintenance cost while accounting for maintenance effects on processing, combined maintenance activities, and uncertainty in processing and maintenance times.
