Case Studies

Included in this section are case studies for some of our major international & national clients outlining the challenges they faced and how Orbit Systems were able to utilize Operations Research techniques and systems to overcome the challenges. Each of the clients below has seen significant benefits from the introduction of our solutions, including over USD$4,000,000 saved per annum.

Optimisation Systems

Our staff have advanced degrees in the theory of Operations Research, and we have added to the theory with years of practical application in this area. Recent advances in both computing power and mathematical solvers available have made a number of “too hard” problems a possibility for solution by text-book solutions thought to be too complex for a “real world” problem.

In a recent project, we solved a multi-commodity network distribution model for NZ Post that would have been impossible even 2 or 3 years ago.

While direct optimisation is not always possible, Orbit Systems is well equipped to determine whether optimisation is appropriate, and to handle this type of project.

Our capabilities include

Linear, quadratic and non-linear programming
Dynamic programming, including stochastic dynamic programming
Stochastic optimisation and decision trees
Game theoretic models
Network modelling and routing

Example Products & Services

Orbit Systems uses GAMS, CPLEX and Matlab for many optimisation projects.
Dublin: A Cournot-based oligopoly model that incorporates multiple nodes and hydro reservoirs. This model was successfully used to show the Commerce Commission the effects on competition of Contact Energy’s $500 million purchase of a power station in New Zealand.
