Opis:
The maintenance of helicopters at the airports of the Polish Armed Forces in the state of technical efficiency determines the possession – by the entity securing their maintenance, repair – of appropriate resources and the maintenance system. The article presents the current state of the operation processes of helicopters in the Polish Army. The characteristics of the helicopter maintenance system model and the basic assumptions were described, and the mathematical records of input data to the system were identified and presented. The selected elements of the optimisation task, its decision variables, and constraints were formulated. The initial assessment of the quality of the proposed solution of the helicopter maintenance system model. The essence of the system optimisation problem, which relates to minimising the cost function and maximising the system’s readiness function, was emphasised. In addition, an example of appropriateness of applying such an approach is presented on the basis of the School Aviation Base. The article was concluded with a short summary, which stressed the importance of this type of the optimisation system.

Opis:
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).

Opis:
Transport is one of the most environmentally destructive branches of economy. It contributes to environmental degradation and influences negatively on human live. It should therefore seek to reduce the negative impact on the environment. The paper presents many aspects of development of the national transport system. In article characterized technical constraints and environmental issues, which are applicable to the designing of pro-ecological transport system. Presented in it also indicators of the proposed design solution quality. In shaping the pro-ecological system the special role plays environmental restrictions, because they mainly determine the quality of solutions in terms of minimizing the negative impact of transport on the environment. Technical factors are equally important, because they allow, among others, reducing the external costs of congestions and allow on the creation of transport tasks on the appropriate level. In particularly, EU requirements for sustainable development of the transport system, the components of the external costs arising from the sphere of transport, indicators and ecological limitations in designing of pro-ecological transport system, ecological limitations, technical limitations, indicators for assessing pro-ecological transport system are presented in the paper.
