Decision problems,
made explicit.
Case studies go beyond the final metric. Every repository links to working code, assumptions, and the trade-offs behind the result.
DATA SYNCED / BUILD TIME
Predictive Maintenance: RUL + Scheduling
RUL prediction connected to capacity-constrained maintenance scheduling, with uncertainty and negative findings reported explicitly.
ALNS for Pickup & Delivery
Adaptive destroy and repair operators for pickup-and-delivery routing with time windows, capacity, and precedence constraints.
Charging Facility Location & Routing
A multi-part optimization study spanning robust routing, charging infrastructure, fairness, coalition costs, and decentralized behavior.
TSP and VRPTW Optimization
Exact routing formulations under capacity, time windows, vehicle penalties, and driver working-time constraints.
UFL Lagrangian Heuristic
Lower and upper bounds for uncapacitated facility location using Lagrangian relaxation and subgradient optimization.
TSP Optimization Heuristics
Constructive heuristics, GRASP, 2-opt, and iterated local search compared on Euclidean TSPLIB instances.
Hospital Outpatient Simulation
A discrete-event model of appointments, walk-ins, doctors, X-ray rooms, priorities, queues, and time-dependent service.
Queueing Models Calculator
An interactive desktop calculator for five M/M/* queueing systems and their operational performance measures.
Generalized Assignment — TA
A capacity-aware Threshold Accepting metaheuristic evaluated against a Gurobi LP-relaxation lower bound.
