From concept to daily operational use

Amal has built optimization systems for logistics, transportation, aviation, energy and manufacturing — the industries where a scheduling decision is measured in vehicles, aircraft or shifts rather than percentages.

That work covers most of what Gradient Path now does. Bus driver routing, aircrew scheduling, aircraft tail assignment, rail maintenance crews, locomotive and railcar movement, airport gate allocation — each built, deployed and put into daily operational use, several still running. Before founding Gradient Optimization he was a Senior Research Scientist at Apple; earlier, at Gurobi Optimization itself, solving modelling problems for customers across transportation, energy and finance.

PhD in Computer Science and Operations Research, Griffith University. MEng in Industrial Engineering and Management, Asian Institute of Technology. BSc in Electrical Engineering, University of Moratuwa.

Core expertise

What the work involves.

Mathematical optimization

LP and MIP modelling, constraint programming, and heuristics — genetic algorithms, simulated annealing, tabu search.

Scheduling & routing

Workforce, crew, fleet and asset problems, at the sizes real operations actually run.

Advanced analytics

Simulation and stochastic models where the inputs themselves are uncertain.

Operationalization

Getting models out of notebooks and into production systems people depend on daily.
