Efficiency as an assessment measure of warehouse facilities location in logistics network

The paper presents an approach to the assessment of the location of facilities in the warehouse logistics network with the efficiency of its operations. Determination of efficiency of complex systems of this type should take into account wide range of issues. The system efficiency results on the one hand from the efficiency of its action and on the other hand from the ability to use available system elements to achieve the objectives. Efficiency is a main criterion to the evaluation of the activity both at the level of the whole system, as well as in its subsystems or components. Most often, it refers to the principle of rational management formulated in two variants: performance (maximization effect) and economical (minimizing effort). The article poses the thesis that based on studies of speed and reliability of execution of tasks it is possible to assess the potential locations of warehouse facilities in the studied logistics network. Were also presented factors affecting the efficiency of the functioning of individual cells of the logistics network. Was pointed to the technical, economic, organizational and reliability aspects affecting the efficiency and reliability of the logistics network in terms of both supply and distribution. It was also presented a modular block diagram of an assessment method for localizing logistics facilities in the logistics network.
