Resumen
The premise for approaching the subject is the need to support companies in selecting the best stock replenishment system, taking into account all external or internal limitations related to delivery terms and order volumes assuming that safety stock is the central factor ensuring the achievement of the intended availability level. In order to meet the objective, several stock replenishment systems are briefly described. Then, prerequisites for their proper selection are identified and classified. As a result, a selection table is developed along with an algorithm for selecting an optimal stock replenishment system based on an economic or qualitative criterion.
