Problem type: MIP (small)
Keywords: Piecewise linear, special ordered set, SOS2, network object.
Description: The Piecewise Linear Transportation problem models a simple transportation model with one complication, namely the objective function representing the cost is a piecewise linear function. This piecewise linear cost function is used to model price discounts. The piecewise linear function is modelled using the integer linear programming trick of Chapter 7.6 of the AIMMS Optimization Modeling book.
Note: The Piecewise Linear Transportation problem is described by Christensen and Labbe (2015) but the model formulation in this project differs from their formulation.
