The impact of the pantograph of a rail vehicle on the overhead contact line depends on many factors. Among other things, the type of pantograph, i.e., the material of the sliding strip, influences the wear and possible damage to the sliding strip. The possibility of predicting pantograph failures may make it possible to reduce the number of these k...

Damage to the pantograph or sliding strip may cause the blocking of the railway line. This is the main reason for which the prediction of pantographs' failure is important for railway carriers and researchers. This article presents a sliding strips failure prediction method as a main means of preventing disruptions to the transport chain. To develo...

A Sybil attack, where a malicious node creates multiple fake or captured identities, is one of the most well-known attacks against wireless sensor networks (WSNs). This attack can leave devastating effects on operational and routing protocols, such as voting, data aggregation, resource allocation, and misbehavior detection. In this paper, a simple...
Article

In this study, the authors have investigated warehouse processes to identify critical ones that are wasteful. The aim of this research study was to improve the efficiency of warehouse processes by reducing travel time and cost in replenishment and order picking. To achieve this objective, the authors have proposed a mathematical model and discrete...
Article
Full-text available
The most important factors conditioning the competitiveness of a warehouse are time and money. A randomly or improperly chosen storage process influences three types of costs: the movement of goods, waiting time, transportation costs. To increase the effectiveness of goods completion, i.e. to decrease processing time and cost, appropriately selecte...

The article looks at the simulations of the possibility of theft risk occurrences with taking into account different types of cargo, its price and a carriage phase. The risk analysis was conducted by using original algorithms developed on the basis of artificial neural networks that take into account, among others, the probability of the cargo thef...
Article
The research was carried out to verify the impact of using systems to monitor cargo location and parameters in the transportation chain. Three variants of cases were examined – a reference variant (without cargo monitoring systems), variant I (positioning systems), and variant II (monitoring cargo location and parameters). It was possible to assess...
Conference Paper
Just-in-Time (JiT) system, used by most manufacturing companies, is being increasingly replaced by more efficient Just-in-Sequence (JiS) system. The latter one allows direct delivery of products to the production line without the warehouse storage process. In this paper the impact of JiS application on the effectiveness of internal transport system...

In the first part of the article describes the main factors influencing the development of outsourcing and the benefits from the use of the outsourcing companies. Currently in Poland the services industry what is TLS represents only about 15% of the companies using the outsourcing services. In the second part discusses the courier services market i...
Conference Paper
Full-text available
Transport is an essential element of global supply chains and therefore the intermodal transport increasingly becomes popular. The risk analysis for each element of the supply chain, including the identification of occurring risks is extremely important for the functioning of the supply chain. Risk identification allows taking actions aimed to redu...
Conference Paper

In this paper, presented selected aspects of the impact that the distribution of products in a warehouse has on the picking of orders. This problem is particular important for medium and large warehouses characterized by considerable rotation of goods. The aim of this study was to assess the impact of the method of classification of products that w...
Article
Full-text available
The organization of cargo loading and unloading processes onto railway wagons is more problematic than in road transport. It is due to large volumes of loads transported by rail. The loads are usually oversized. Their loading requires a significant amount of work put into moving rail wagons and a lot of shunting work. Such operations generate consi...

In this paper a dedicated online support system has been described. The system was developed to forecast a fuel consumption by buses and to support determination of fuel consumption standard. The system, based on route characteristics, vehicles parameters and information dealing with the driver driving style and skills, make it to forecast the fuel...

Using the example of one of the biggest suppliers of automotive parts and sub-assemblies, the article presents the JIT (Just in Time) and JIS (Just in Sequence) deliveries based on the SAP system. JIS means that parts are pre-sorted into bins by the supplier, so that assembly workers can withdraw these parts in the right order just as defined by th...

Project
Project goal: Development of a data collection solution for moving objects in the enterprise, enabling multi-dimensional data analysis and proactive management support. Project description: The implementation of the project will allow obtaining information about all the traffic taking place in the enterprise and to perform multidimensional analysis of the acquired data. In order to get the information needed for the project implementation, it will develop a real-time location-based technology that is dedicated to environment variables. The developed technology will be implemented as a prototype called SKK Hive Analysis. The implementation of this project will be based on the development of its own Bluetooth 4.0-compliant (Bluetooth Low Energy) solution for object localization. This standard was chosen due to low power consumption, so transmitters can work on their own power supply (battery life of about 2 years), so there is no need to upgrade the power grid in the Enterprise. In addition, the technology used will increase the precision of locating objects. The result of the project will be the development of a fully functional, real-time closed-space facility dedicated to industrial applications.
