Job ID: 32884382

Budget: $50 – $120 AUD

I need someone to solve a mathematical model to optimize a supply chain (minimize costs).
the optimization to be done using Gurobi optimizer ( useful library for optimizing SC) and python language (Spider).
you must be experienced in optimization + coding.
80 % of the code is ready with some errors.
The mathematical model has an objective function of minimize cost and number of linked constrains.
Sample of work need to be provided.
