Because night vision intensifier tubes are produced with highly variable qualities, they are binned and sold in discrete grade batches. This wastes money and degrades overall system performance. With two mixed-integer linear programs (one for grouping tubes into systems, and another for assigning systems to customers), OptimalNightVision is able to greatly improve end-product quality and reduce costs.<p>OptimalNightVision is the only (publicly available) inventory optimization platform for night vision intensifier tubes.<p>Tech: Django, Pyomo for formulation, GLPK for solving.<p>Feedback and questions are very welcome :)
