Integer and Binary Linear Programming - 5 - Application Example

There are two main reasons for using integer variables when modeling problems as a linear program: 1. The integer variables represent quantities that can only be integer. For example, it is not possible to build 3.7 cars. 2. The integer variables represent decisions (e.g. whether to include an edge in a graph) and so should only take on the value 0 or 1. WebExample integer programming problems include portfolio optimization in finance, optimal dispatch of generating units (unit commitment) in energy production, design optimization …
