An analysis of dynamics of demand-inventory model formulated with a system of three first order difference equations with three parameters. The origin, rules, assumptions and example of application are presented. The numerical analysis is performed using bifurcation diagrams and phase portraits. Graphical observation of evolution of trajectories suggests chaotic behaviour occurrence. © 2017 Author(s).

Cooperation in the supply chain requires a lot of information exchange between different companies. In order to achieve appropriate data exchange open communication standards are needed which are commonly agreed and approved. In the field of logistics a number of standards already defined. The aim of the paper is to compare existing communication standards to the market needs and expectations. Authors present conclusions from pilot survey conducted within selected group of transport users and logistics service providers regarding information exchange by planning and execution of transport services. © 2012 Springer-Verlag.

Companies are facing problems regarding reduction of their logistics costs. Good organization of transport processes can bring a lot of profits both economical and environmental. Companies participating in supply process more and more often prefer to create temporary relations and form virtual cooperation networks than to keep traditional long-term contracts. The aim of the paper is to present the tool that supports the coordination of transport in virtual logistics clusters. The main problems and requirements are identified. Moreover authors present the results of questionnaire conducted among transport users and transport providers regarding the communications standards. © 2012 Springer-Verlag.

The improvement of transport processes gains a lot of interest from enterprises and governments. Configuration of supply chain should meet both economical and environmental goals. Companies participating in supply process more and more often prefer to create temporary relations and form virtual cooperation networks than to keep traditional long-term contracts. The aim of the paper is to present the potential of multiagents application for coordination of processes in virtual supply chain. The theoretical background of the project is presented. The main problems and requirements of the virtual supply chain coordination are identified. The reference model is described. Finally authors present a case study from pharmaceutical industry. © 2011 Springer-Verlag.

The common access to the broadband Internet allows small and medium enterprises (SME) to joindifferent cooperation network. For over decade European Commission in order to fulfill the obligations of sustainable policy promote intermodal transportation. Despite all these efforts the utilization rate of road transportation is still growing reaching last year 76,9%. Intermodal cargo may be carried out in one and the same loading unit or vehicle, on the whole route from the sender to the consignee using the different modes of transport. Planning and coordination of intermodal transportation requires participation of different companies. The main problem still is lack of consistency between processes which are undertaken by various supply chain participants. The aim of this paper is to propose the concept of broader cooperation between intermodal transport process participants based on semantic web and multi-agent system. The application of semantic web and multi-agent system allows to improve the information exchange among different companies and better intermodal transport planning and coordination. © 2011 Springer-Verlag Berlin Heidelberg.

Global real-time monitoring of means of transport and freight is necessary if we want to use the available resources in a sustainable way. Up-todate information about the fleet and cargo can also improve the efficiency and effectiveness of the logistics processes organization in supply chains. Such monitoring also enhances transport security. Generally accessible solutions for global tracking, however, are expensive and quite unreliable. The purpose of this article is to present the concept of the T-Traco system, which is used for global tracking of vehicles and cargo. Its main advantage, in comparison to the existing solutions, is the use of the USSD communication channel, which is more reliable and much cheaper than GPRS and SMS. © Springer International Publishing Switzerland 2015.

The work presents a method of the vehicle routing and scheduling using the modified Branch and Bound Simulation method for vehicles simultaneously carrying loads from multiple orders. Limitations concerning vehicle loads and time windows in pickup and delivery points are taken into consideration. The developed algorithm appoints the shortest, the fastest and the cheapest routes with a certain known accuracy. A modification of the BBS method is described A sample of result using Google API is shown.

2015 IEEE International Conference on RFID Technology and Applications, RFID-TA 2015 | Year: 2015

The aim of the study was to determine the effectiveness of the use of RFID technology in selected processes at store with construction materials of the one of DIY retail network in Poland. During the research, author was focused on examination the effectiveness of the use of RFID tags and determination the efficiency of the process compared with traditional barcodes or manually performed actions. For the purpose of the study, 120 000 items within the store had been marked with RFID tags, all hardware components of the system were selected and connected with the existing IT environment through the use of dedicated applications and interfaces. Results of this study confirmed the high efficiency of RFID technology while pointing to problematic areas and products, requiring individual approach and carry out further tests. The study also showed "weaknesses" on the side of the retail network, which in the case of a decision to the full implementation must be subjected to a thorough change. Among of these areas the most important are: IT environment, construction of trolleys, the design of some of the shelves and the course of selected processes. © 2015 IEEE.

Current model of organization of supply chains results in inefficient use of transport resources, high transport costs, increasing congestions and CO 2 emission. This effect has been demonstrated by research conducted by the author as well as by the European Environmental Agency. This situation can be change by development of alternative business model for collaboration in organisation of the transport processes within the supply chains. The aim of this paper is to present practical implementation of the developed by the author T-Scale platform that enables collaboration between independent transport users and transport service providers. Moreover, an overview of existing communication platform with its major functionalities are presented. The work is summarized by the major benefits of collaboration achieved by the group of companies operating in the FMCG sector in Poland. © 2013 Springer-Verlag.

In the age of rapid economic changes, companies are forced to continuously search for ways of transport and logistics processes rationalization. For manufacturing and distribution companies reduction of logistics costs and in particular transport ones is the most important. The aim of the chapter is to present concept of cooperation between group of manufacturing and transport enterprises in the sphere of transport processes̀ implementation in supply chains. Author is going to describe new business reference model for the entire supply chain that would cause positive effect on enterprisès activity in the short and long term (load factor) and also on the region in which the enterprise operates. Presented model will be validated in real business cases with participation of the industry. © Springer-Verlag Berlin Heidelberg 2011.
