Editing Integer programming (section)

===Production planning===
Mixed-integer programming has many applications in industrial productions, including job-shop modelling. One important example happens in agricultural [[production planning]] and involves determining production yield for several crops that can share resources (e.g. land, labor, capital, seeds, fertilizer, etc.). A possible objective is to maximize the total production, without exceeding the available resources. In some cases, this can be expressed in terms of a linear program, but the variables must be constrained to be integer.
