Optimisation of aircraft maintenances in the polish armed forces

Maintaining the aircrafts (AC) of the Polish Armed Forces in operating condition is determined by adequate resources to secure maintenance and repairs possessed by the companies implementing these tasks on them. The article characterises and then describes formally the Aircrafts Maintenance System in the Polish Armed Forces. The assumptions of the aircraft maintenance system model, proposed model structure, and mapping of aircraft maintenance performance were described. The most important elements (such as data, decision variables, boundary conditions and assessment criterion function) of an optimisation task aimed at minimising the executed aircraft maintenances’ costs were formulated. For this purpose, the record of evaluation criterion functions of the companies performing aircraft maintenance was shown. The article was completed with a conclusion, which underlined the importance of the proposed optimisation model. The optimisation model proposed in the article allows evaluating the aircraft maintenances’ organisation and their parameters. The formal record concerns both in the case of one-dimensional maintenance (one aircraft type) and multi-dimensional one (various aircraft types)
