Methods for Calculating the Efficiency of Logistics Centres
Journal Title: Archives of Transport - Year 2013, Vol 27, Issue 3
Abstract
Changes in the organization of the transport system, such as building a logistics centre, bring them uncertainties linked with the risk of investments failure. One of the first steps of creating such a logistics centre is carrying out a thorough economic analysis. Localization and organizational analysis and then the assessment of the functioning of the future centre is possible mainly thanks to the economic effectiveness calculation, which takes into account the expenditure, the operating costs, and benefits of creating a logistics centre in a selected place and gives the answer concerning the reasonableness of organizing such a centre. The article describes various types of the economic effectiveness calculations. As a result of the analysis performed a formula has been suggested, which can be used in the case of estimating the rationality of organizing a sample Logistic Centre consisting of four infrastructural elements. All of the described above simple and complex methods for calculating economic efficiency are the starting point for a discussion on the use of REE calculation for Logistic Centre in Southern Podlasie.<br/><br/>
