A typical non-convex problem is that of optimizing transportation costs by selection from a set of transportation methods, one or more of which exhibit economies of scale, with various connectivities and capacity constraints. An example would be petroleum product transport given a selection or combination of pipeline, rail tanker, road tanker, river barge, or coastal tankship. Owing to economic batch size the cost functions may have discontinuities in addition to smooth … WebMixed-Integer Nonlinear Program 3 minimize f(x,y) subject to g j (x,y) ≤ 0 j ∈ J Ax + By ≤ b x continuous y integer Important special cases: Convex MINLP: f and g j are convex MIQP: f is ...
