INDUSTRY: Metals and Mining

REGION: Australia / New Zealand



To provide accurate, optimized consulting services to mining companies with no prior optimization model building experience.


AVCS was able to access a trial license of Gurobi, its training documentation, and customer service to develop a quality solution for their client, in spite of not having any experience with optimization.

Easy Learning Curve: From idea to full concept model in a few days

AVCS staff accessed the Gurobi website and it wasn’t long before the latest version of Gurobi was fully installed, trial licensed and it was loaded into VB.Net to commence modeling. Gurobi’s online help and sample models are a godsend for people who have no prior optimization model-building experience. With the ability to break down the problem into a series of logical components, AVCS staff immediately commenced developing its first MILP optimization model.

In the space of a couple of days, the model progressed from just an idea into a full-blown concept program that would function on a small dataset running the trial license to demonstrate a properly optimized solution. The model-building process was very straightforward using the .NET interface and having the ability to define the optimization problem using easily understandable logical expressions rather than requiring a PhD in applied mathematics was fantastic.


The Results: Adoption by both consulting firm and client

This modeling endeavor ended positively for everyone involved; AVCS and the client both ended up purchasing Gurobi licenses, the client has a fantastic product which allows them to complete an almost impossible task quickly and easily, and AVCS was given the opportunity the develop internal optimization model building capabilities.

Subsequent to this initial work, AVCS has already developed an internally used software product for another common and complex mine engineering task and we are looking forward towards our next development opportunity with Gurobi.
