Train Set Organization (TSO) is to arrange the train set in railway freight transportation. Bilevel programming techniques were proposed to solve the Stackelberg game in which play is sequential and cooperation is not permitted. In this paper, an optimizing model for TSO is developed by the bilevel techniques. First, we analyzed the multiple level nature of management on TSO and simplified it i...

In train collisions, multi-level rail passenger vehicles can deform in modes that are different from the behavior of single level cars. The deformation in single level cars usually occurs at the front end during a collision. In one particular incident, a cab car buckled laterally near the back end of the car. The buckling of the car caused both lateral and vertical accelerations, which led to u...

The Propose of this paper is to introduce a new model for crude oil fouling in preheat trains of crude distillation unit. The experimental results of Australian light crude oil with the tube side surface temperatures between 200-260 oC and fluid velocity ranged 0.25 to 0.4m/s were used. The activation energy of chemical reaction depends on the surface temperature has been calcula...

Safety is important as technology advancement increasing daily. Accidents in transportation industry happen every day and given bad impact to the industry. Public transports become an alternative to the urban people, as the traffic congestion getting worse today which will results on increasing number of locomotives, as to fulfill the service demands, at the same time will increase number of tr...

The most important operating problem for intercity rail lines, which are characterized with the train operations at rapid speed and high frequency, is to design a service-oriented schedule with the minimum cost. This paper proposes a phase-regular scheduling method which divides a day equally into several time blocks and applies a regular train-departing interval and the same train length for e...

In this paper we present an optimization model for train scheduling. This model constitutes one of the three major components of a solution approach for solving the transit network design problem. The problem of scheduling can be defined in the following general terms. Given the origin destination matrix for the train trips for design period, the underlying train network characterized by the ov...

This paper addresses the determinants of three types of railroad related fatalities: trespasser fatalities, those at grade crossings, and those involving passengers and employees. Of particular interest are the effects of railroad deregulation (the Staggers Act) on railroad related fatalities. Models are developed using specification error analysis and seemingly unrelated regression. Deregulati...

In model-driven development of safety-critical systems (like automotive, avionics or railways), wellformedness of models is repeatedly validated in order to detect design flaws as early as possible. Validation rules are often implemented by a large amount of imperative model traversal code which makes those rule implementations complicated and hard to maintain. Additionally as models are rapidl...

This paper addresses first experiments in the usage of model engineering to generate control/command code from a high-level description of the system featuring the notions of architecture and configuration. This principle has been applied generate IEC-611313 control/command code for an industrial PLC to control the circuit and the engines of an electric train. It has been implemented using the ...

In this paper we analyse a multi-server queueing model with locking. The model is motivated by a situation we encountered at a maintenance facility for trains. Maintenance is done at parallel tracks, where each track ooers space to two trains. Trains can enter and leave the tracks from one and the same side only. This gives rise to locking of the front train: in order to leave the maintenance t...
