Some Aspects of the Application of Genetic Algorithm for Solving the Assignment Problem of Tasks to Resources in a Transport Company
Get PDFThe article defines the assignment problem of tasks to resources in a transport company. The paper describes mathematical model of a transport system taking into account the assignment of vehicles to the tasks. It also provides stages of creation of the genetic algorithm for solving the assignment problem in the transport compan
Towards the Best Public Transport in Suburban Areas on the Example from One Polish Agglomeration
Get PDFThe aim of this paper is to find the best public transport system suitable for suburban areas. Two measures of evaluation are developed, in sense of spatial and temporal accessibility. Three options of transport system are evaluated with the use of these measures, with consideration of different time horizons. The first option was the existing bus system. The second option concerns the modification and development of the bus system with the addition of rail transit. A futuristic "dial-a-ride" system is studied in the third option. The ranges of residences from past, present and future are shown for selected time horizons in relation to transportation network. The study concludes that only advanced "dial-a-ride" system can offer good conditions for people who choose public transport means compared to private car transport. The analyses were conducted for an exemplary village located within one Polish agglomeration. The conclusions could be adopted in other cities and countries due the similarity of urbanisation and transportation processes around the whole worl
Engineering Graduate Studies for Public Security Professionals: the Bachelor Thesis at the End of the Studies
Get PDFThis work presents the latest results concerning the Bachelor Thesis developed at the end of the fourth course in the Security Engineering Degree. A combined approach has been selected applying technological issues to crime problems, and also attending to legal and social aspects involve
Challenges of Innovation in the Developing Countries. The Need for Engineers' Education
Get PDFThere has never been any doubt about the importance of promoting innovation that speeds up the development of all domains of our lives. Processes, services, products, everything needs to be improved in a permanent way. However, to innovate means to make effort. Kline has proposed a chain-linked model that describes the innovation process. The market need is the main source to innovate, but a proper interaction between production, marketing and R&D is required to dynamise innovation. The performance of innovation can be measured by the number of patents, R&D applications or professional literature citation
Fast Screening Method for the Assessment of Freight Demand at the Initial Planning Stage of a New Transport and Logistics Centers
Get PDFThis paper presents an empirical approach that allows pre-feasibility assessment of logistics infrastructure for defined locational and fleet constraints. It aims at developing a fast screening method for the assessment of demand of a public Transport and Logistics Center, which is important for properly selecting the Center’s size and minimising the risk of over or under-estimation of capacity needs. The results are useful for policy makers to facilitate the early planning and commercialisation phases of a TLC project. The method develops the appropriate cost functions in order to compare two logistics strategies: one that involves the use of TLC to achieve economies of scale, and another one that assumes direct deliveries from origin to destination to save time and handling costs. The method has been applied as a pilot study in a case of a regional Center in Greece, advocating its applicability and reusabilit

Implementing Risk Management Principles in the Traffic and Transportation Processes
Get PDFThe paper is based on the basic safety and security factors of the traffic and transportation systems. It identifies the main groups and types of risks in traffic based on the particularities of the traffic and transportation systems. In general it characterizes the scope of the individual risk management phases in traffic conditions. It specifies successive steps of risk management and forms of their outputs in transport enterprise
Function of Motive Situation in Procedure of Leadership of Train Equipped with System ERTMS
Get PDFThe Railway Infrastructure Manager in Poland initiated the implementation of the ERTMS system. This paper presents the description of level system, modes of work traction vehicles, basic parameters of system and also the exemplary principles of the system operations. These parameters are the elements used by operating scenarios which describe the behaviour in traffic situations on railway lines included in the development of the ERTMS syste
