Improvement of Vehicles Maintenance Management Process Performance Through the Implementation of Controlling

The article raises an important issue concerning the reporting systems which are used in transport companies. Research conducted by the author focused on the reporting system which functions in maintenance service station of one of the largest road transport operators in Poland. The goal of this article is to analyse the current reporting system in force in the audited company and to develop a model solution, supporting the management of vehicles maintenance performance. Prepared model should incorporate the concept of controlling

The Potentials in the Integration of Planning Enterprise Activity

Planning, including planning in logistics, consists the primary function of management, as it is logically and chronologically first in the management process. The efficiency of the subsequent activities in the company depends on the proper realization of this stage. Therefore, finding possibilities of improving this part of management process, aimed at reducing the risk of undertaken planning decisions, creates an important issue in the research activity. One of the possible ways of improving planning process is to integrate it within internal company's activity, as well as to include it to cooperation with partners. As a result, the aim of this article is to identify needs and opportunities of integration for selected planning levels in company's work

Preliminary safety assessment of Polish interchanges

Interchanges are a key and the most complex element of a road infrastructure. The safety and functionality of interchanges determine the traffic conditions and safety of the entire road network. This applies particularly to motorways and expressways, for which they are the only way to access and exchange traffic. A big problem in Poland is the lack of comprehensive tools for designers at individual stages of the design process. This applies to guidelines or other documents regarding the location, choice of interchanges type and selection of design pa-rameters. This does not provide sufficient material for designing safe and functional interchanges. This situation results in numerous hazards that occur on existing interchanges and errors that are still being made at all stages of the design process. Consequently, there is a risk of accidents in the area of interchanges, which often have serious consequences. The purpose of the research presented in the article is to identify main groups of hazards on the interchanges and to classify them based on field tests and audits of project documentation. The prepared classification uses the results of analyzing data on road accidents. As part of the research, a database was built that includes in-formation on road accidents and traffic, as well as data on all existing interchanges on motorways and express-ways in Poland. These data includes: interchange type, length of exit and entry lanes, total interchanges length, type of cross-section on main roads and ramps. The number and type of ramps occurring at a given interchange as well as the type of intersections, if any, were also taken into account. Based on the assessment, the level of safety was determined for individual types of interchanges. Then, the impact of selected road and traffic factors on safety was presented. The critical elements of interchanges are entries, exits, weaving sections and intersections. Assumptions were also adopted for the classification of identified haz-ards. A comprehensive safety assessment for interchanges allowed the development of assumptions for their design guidelines. On the basis of database exploration and field research, the main problems and hazards regarding the functioning of interchanges were identified

Information flow in CPFR strategy

Information flows are often of greater importance than material and financial flows. As a result the competitive advantage of a company is largely determined by the internal and external communication system. Efficient and timely information exchange are of particular importance for the management of integrated supply chains. However, this information flow may be a barrier for trade partners at the same time. In the light of modern logistic conceptions such as CPFR, where a thorougly prepared system of data exchange between partners is essential, the current challenge is the opening up of companies for the informational needs of their partners
