1. A system, comprising:

  • a supply chain network comprising one or more suppliers and two or more sites;

    a computer system coupled with a database stored on a non-transitory computer readable medium, the computer system comprising a processor, a memory, an object model configured to generate a mathematical model representing an allocation problem as an optimization problem comprising an objective function and one or more constraints, wherein each of the one or more objective functions comprises two or more part variables, each part variable representing a quantity of a part to be procured from the one or more suppliers, the computer system configured to;

    receive the one or more constraints from the database;

    optimize the objective function subject to the one or more constraints to solve the mathematical model and determine an optimized solution to the allocation problem;

    receive one or more inputs comprising modifications to at least one of the objective function and the one or more constraints from the database;

    modify the one or more constraints based on the one or more inputs;

    determine a correlation between the one or more constraints and the resulting optimized solution by solving a new mathematical model based on the one or more modified constraints;

    modify the object model based on the one or more inputs;

    determine a correlation between the modified object model and the resulting optimized solution by solving a second new mathematical model based on the modified object model; and

    determine a quantity of each part to be procured from at least one of the one or more suppliers based on the optimized solution of the allocation problem; and

    cause the quantity of each part to be procured by at least one of the two or more sites based, at least in part, on the optimized solution of the allocation problem.
