Fail-Safe Signalization and Interlocking Design for a Railway Yard: An Automation Petri Net Approach
The most important issue in railway systems is to provide safe transportation. Since no error can be tolerated in railway systems it is an obligation to use reliable signalization and interlocking systems which have to decide what to do in unexpected situations like switch disruptions or signal light defects. By the rapid development in railway systems more formal methods are needed for modelin...

متن کاملScheduling railway freight cars
It is dif®cult to allocate the freight cars and to determine how to load the several varieties of goods into them. In order to improve ef®ciency, a knowledge-based system (KBS) is developed and integrated into the existing railway information system. This paper introduces the development of the system and the framework in which the KBS are integrated into the existing system environments. Under...
متن کاملFlow assignment model for quantitative analysis of diverting bulk freight from road to railway
Since railway transport possesses the advantage of high volume and low carbon emissions, diverting some freight from road to railway will help reduce the negative environmental impacts associated with transport. This paper develops a flow assignment model for quantitative analysis of diverting truck freight to railway. First, a general network which considers road transportation, railway transp...
متن کاملA New Document Embedding Method for News Classification
Abstract- Text classification is one of the main tasks of natural language processing (NLP). In this task, documents are classified into pre-defined categories. There is lots of news spreading on the web. A text classifier can categorize news automatically and this facilitates and accelerates access to the news. The first step in text classification is to represent documents in a suitable way t...
