The system of IT support for logistics in the rail transport

Abstract

The paper presents the requirements, architecture and important features of a modern IT system of logistics for rail transport. The purpose of the system is to provide logistic support of transport issues relating to the work performed in the sectors of transport and maintenance of railway enterprises. In particular, special attention was paid to optimization problems of strategic and operational planning applying modern optimization algorithms. System architecture, the basic functional modules and their relationship are presented as an example of the system used by the Polish rail operators, engaged in the transport of both passenger and freight. The system is characterized by centralized architecture, divided into an application server, a database server and a terminals server. The system takes full advantage of modern mobile technologies. The study outlines basic logistics processes implemented in the system, among others,: planning of transport using background maps and a scheme of railway network, records of vehicles and employees, allocation of transport work for individual units, planning cycles of vehicles and trains, scheduling work for vehicles, train driver crews and train attendant teams, creating work schedules, short-term and long-term dispatches, verification and accounting of the work time, accounting transport and train drivers performance.

Ensuring the economic and environmental efficiency in managing the flows of construction and demolition waste by using tools of economic and mathematical modeling

“…It is assumed that the information and logistics system (centrally) should solve the problems of collection, transportation, and distribution of waste flows from construction and demolition, respectively, the transport task is an important component of the information and logistics system [21]. In this case, the transport problem should solve the problem of waste delivery as potentially secondary raw materials to the processing plant.…”

Modele decyzyjne w systemach informatycznych wsparcia logistyki dla transportu kolejowego

“…Dane z modułu "kartoteka pracowników" są niezbędne m.in. do planowania pracy personelu czy rozliczania czasu ich pracy [Kisielewski 2016]. Kartoteka infrastruktury zawiera dane ewidencyjne, fabryczne i techniczne infrastruktury kolejowej, mapę sieci kolejowej oraz dane aktualne na temat wyłączenia infrastruktury kolejowej z użytkowania.…”

“…Następnie, na podstawie dostępności infrastruktury i pojazdów kolejowych, dokonuje przydziału pojazdów kolejowych do zaplanowanych obiegów. System powinien zaplanować najbardziej efektywny plan z punktu widzenia pracodawcy, biorąc pod uwagę wszystkie przepisy krajowe i wewnętrzne [Kisielewski 2016].…”

Inventory Management of Railway Logistics Park Based on Artificial Neural Network

“…As the core logistics system in China, railway logistics gains advantage and realizes centralized transport from the numerous railway stations and lines across the country [1][2][3]. With the development of information technology (IT), the economic advantages of railway logistics have been highlighted in production and operation (P&O), and infrastructure.…”
