Dynamic Lotsizing (Windows 10, Windows 10 Mobile)

Solve the dynamic single-item uncapacitated lotsizing problem, also known as Wagner-Whitin problem.

  • Exact solution
    • dynamic programming
  • Heuristic solution with
    • Silver-Meal heuristic (minimize costs per period)
    • Groff heuristic (equate marginal setup and holding costs)
    • Least unit-cost heuristic (minimize costs per unit)

The heuristics are used in many standard MRP and APS software systems. Here is an illustration of the Silver-Meal heuristic:
