Opis:
The article discusses the problem of computer aided decision making processes in inland waterway transport. Inland waterway transport is of minor importance in the Polish transport system. One of the reason for this is the difficulty in making decisions about transportation. This is due to the high variability of navigational conditions on Polish waterways, thus the low reliability of this mode of transport. This does not change the fact that the inland waterway transport of bulk goods, oversized and hazardous materials is the most efficient and least burdensome means of transport. For this reason, one should aim to increase the share of freight with the use of inland vessels. The paper indicates the possibility of supporting decision making processes in the organization of inland waterways transportation. For shippers or other persons organizing transport of goods, various issues can be important: the cost of transportation, delivery or handling method. Often, due to the lack of appropriate tools transportation is directed to the cars. Access to appropriate computer programs that calculate of the some parameters for the carriage or optimization criteria, may increase the use of inland waterway transport, and consequently a reduction in external and social costs, associated with carriage of cargo. The paper describes the possibilities.

Opis:
Electronic equipment used in transport operates under various conditions. Due to characteristic nature of their application, they should be highly reliable. This paper presents a methodology of optimising a bistable operation process of those systems factoring in economic factors, i.e. the funding allocated to routine inspections. Its practical application was also discussed, which would entail computer aided maintenance software.

Opis:
This paper describes an application of the dynamic programming method to determine the safety of one’s own ship trajectory during encounter of other ships. A dynamic model of the process, with kinematic constraints of state and determined by a three-layer artificial neural network has been used for the development of control procedures. Non-linear activation functions in the first and second layers may be characterised by a tangent curve while the output layer is of a sigmoidal nature. The Neural Network Toolbox of the Matlab software has been used to model the network. The learning process used an algorithm of backward propagation of the error with an adaptively selected learning step. The considerations have been illustrated through an example implemented in a computer simulation using the algorithm for the determination of the safe ship trajectory in situations of encounter of multiple ships, recorded on the ship’s radar screen in real navigational situation in the Kattegat Strait.

Opis:
The paper introduces the process of safe ship control in collision situations using a differential game model with m participants. The basic model of process includes non-linear state equations and non-linear, time-varying constraints of the state variables as well as the quality game control index in the forms of game integral payment and final payment. As an approximated model of the manoeuvring process, a model of a multi-step matrix game in the form of a dual linear programming problem has been adopted here. The Game Control (gc) computer program has been designed in Matlab/Simulink software in order to determine the own ship safe trajectory. The considerations have been illustrated with computer simulation examples using the gc program for determining safe own ship trajectory in real navigation situations when passing commonly-encountered ships.
