The paper presents the development of inter-branch transport based on the example of Gdansk Airport. It was characterized as the Pomeranian Metropolitan Railway as one of the carriers in the forwarding-and-discharging system of this port. The forecasts for the development of transport by the Pomeranian Metropolitan Railway Passengers using the Gdańsk Airport were determined.

The basic problem concerning the waste management system is work organization, which should be effective with maximum profit and minimum financial outlays. This means that the key factor for the efficient functioning of this system are all types of costs. When collecting waste, the main operational cost factors are the driver's working time and the service time of the waste collection vehicle, as well as the route that the vehicle has to cover. The article presents route optimization solution for a vehicle collecting urban waste (both mixed and segregated) is a simple method of determining the order of driving through individual city streets. The prepared solution is universal and is not limited only to the surveyed housing estate. It presents a pattern that can be applied to other routes in a similar way. Shortening the distance and thus the working time is a result of minimizing empty runs and moving several times over the same section. Developing an optimal route for so many values requires very complicated calculations and would not reflect the real possibilities of waste collection by employees and MZGK Company. The presented solution can be used as an instruction to take the first steps to optimize the operation of the vehicle and as an initial point for further modifications of the operating system.

In this paper the synthesis of models and algorithms to identify situations at the orthogonal structure of decision rules in simulation management tasks and operating indicators in production systems was accomplished. Necessary and sufficient condition for identification of decision-making situations was formulated and proved.

The paper uses the diagnostic survey method to analyze consumer preferences in the field of air ticketing, with particular emphasis on the role of modern information technology. On the basis of the research, it has been unequivocally stated that passengers are heavily involved in the use of information technology in the area of ticket purchase and booking, which highlights the great importance of technological innovation in the operation, promotion and further development of services in the air transport market.
