A Methodological Approach to Modelling National Input-output Logistics Flows

Abstract

The effective management of logistics flows requires the right methodology and tools, which can be used on all managerial levels, including national. In particular, in the aspect of the real problem of increase of the effectiveness of Poland's logistics system, it is necessary to develop a model of macro-logistics flows as a managerial tool to all its decision-makers. This real problem initiates scientific questions of a methodological character, in particular how to model the national input-output logistics flows, how to construct such a model, and some more general issues regarding the national logistics system, its aims and structure, if the model and modelling are assumed to be core management elements of the system. Thus, the national input-output logistics flows are the object of research, which is aimed to develop a model of these flows, especially in the case of the Polish economy. The above aim is carried out with the usage of the following methods: literature study, input-output table and Sankey diagram.
