The paper describes deployment experience of a decision support system for planning fuel supplies within a network of gas stations, which is based on simulation, multi -agent and expert modeling. Authors focus on various methods used in decision support system BPsim.DSS. Mainly the system is used by logistical management and planning departments. The system implement such features as forecastin...

It is proposed to install a hybrid fuel cell electric propulsion system on a domestic ferry. The fuel cell hybrid system is compared with the existing diesel propulsion system for this ferry using a developed time-domain threedegree of freedom ship simulator implemented in the MATLAB/Simulink environment. Performance comparison of the two systems is made in terms of first cost, fuel cost, syste...

Maintaining a fuel cell system in correct operating conditions when subjected to fast load changes requires good system control. In order to design such a controller, a simple PEFC system model describing all the important system dynamics and cross couplings is required. The simple model shown here describes the fuel cell auxiliary systems in a state space approach, linking user input to fuel c...

A high pressure combined air-fuel injection system is designed and tested for an experimental free liquid-piston engine compressor. The application discussed utilizes available high pressure air from the compressor’s reservoir, and high pressure fuel to mix and then inject into a combustion chamber. This paper addresses the modeling, design and control for this particular high-pressure air-fuel...

The paper describes part of an EU research project, aiming at the development of a new distributed aircraft fuel management system, using smart components. Along the research is necessary to develop and check candidate solutions for the distributed control. A simulation system has been created, using two interconnected computers. One of the computers simulates in real time the networked electro...
