The model of procurement process that takes into account the consequences of technical system unreliability (in Polish) Model procesu zaopatrzenia z uwzglednieniem skutków niezdatności systemu technicznego

One of the basic exploitation decision is to choose successful maintenance strategy. A lot of maintenance models accept an assumption that unlimited resources are necessary to make all maintenance actions in the system. This assumption, however, is not accepted by all authors, because usually resources are used according to needs and replenished again. The thesis concentrates on the problem of spare elements provision in the technical systems, when elements are critical from the up-time point of view. Based on the research we can conclude that if one chooses the best inventory order level and order quantity, one should take into consideration reliability characteristics of provisioned system. When the possible severe consequences of system down-time are taken into account, the best parameters of system procurement policy change in comparison with reference models.
