Part-Period Balancing

Public class: PartPeriodBalancingSolver.

Early primary reference:

J. J. DeMatteis (1968), An economic lot-sizing technique I: The part-period algorithm, IBM Systems Journal 7(1).

The classical Economic Part Period is

\[EPP=A/h. \]

The method chooses the cycle whose accumulated part-periods are closest to EPP. It is also widely described as the Least Total Cost / Part-Period Balancing family.

GetEconomicPartPeriod(problem) exposes the threshold used by the solver.
