Problems of Transportation Process Reliability Modelling

Generally speaking a transportation system is a system in which material objects are moved in time and space. Thus, the function of transportation is to realize the movement of persons and goods from one place to another by safety and efficient way with minimum negative impact on the environment. Thus, identification of transportation system needs knowledge in three major areas: – identification of components of the system, – identification of activities involved in putting the transportation system in place, from planning to operation and maintenance, – identification of issues that may not be included in the transportation decision-making processes, although they may be affected by the decisions. The transportation system is a very complex one with different functional characteristics depending on medium of movement, the particular technology used and demand for movement in the particular medium. Aspects of the modes are: – vehicle – each mode has particular vehicle that provide carriage and flow (also non-motorized like walking or bicycle), – the way – each mode has what is called a road, guide way, right of way etc., – control – two form of control are usually present in transportation: – control of the system, – control of the vehicle, – the technology of motion – each mode uses a specific technology to facilitate the movement of the vehicle in its way, – the technology of power − each mode has a particular type of engine designed to provide the most efficient power source for that mode,
