    Opis:
    Introduction/background: The article presents a literature analysis related to the concept of distribution network configuration. The main determinants of network configuration and their impact on key solutions used in networks are also indicated. As a key solution related to the correct management of demand, including forecasting, the author considered centralisation in networks. The article also presents the results of research carried out on 5 distribution networks, in which the correlations between the elements of their configuration and the results of forecasts made using the tool previously created by the author are examined. Aim of the paper: The purpose of the article is to present the concept of distribution network configuration in the conditions of centralised demand forecasts, with the central unit at the level of logistics operator. In addition, the article will consider the hypothesis regarding whether the configuration of the distribution network affects the accuracy of forecasts. Materials and methods: The purpose of the article and verification of the hypothesis was carried out with the help of literature studies, results of the conducted case study, and on the basis of the results of forecasts obtained using the prognostic tool created by the author in the R environment. Results and conclusions: The article demonstrates the basic ability of a logistics operator, working in MDP in the distribution network, to make forecasts and analyse the distribution network. In addition to that, the article presents results indicating that a properly selected configuration of the distribution network has a positive effect on the accuracy of forecasts contained in it.

    Opis:
    Purpose: The main goal of article focuses on identification the main research directions for transferring the function of centralised demand forecasting to 3PL enterprise. To meet this goal the concepts connected with central demand forecasting in distribution network was considered and it was taking into account the meaning of demand management and forecasting in logistics. There were also distinguished the main stages which could include the attributes of central forecasting enterprise. Design/methodology/approach: Paper includes literature analysis connected with centralised forecasting and specification of determinants which could be the main reference point in finding the enterprise able to get the function of centralised forecasting. Findings: According to literature review determinants of distribution network configuration in the centralised forecasting is showed and also there is showed a possibility of transfer the function of centralised forecasting to logistic operator. Originality/value Paper shows determinants of distribution network configuration in the conditions of centralised forecasting and takes into account possibility of transfer this function to logistic operator.

    Opis:
    Purpose: This article addresses the issue of forecasting demand for products flowing in a distribution network conducted from the perspective of a 3PL logistics operator. Its purpose is to present a tool based on the R software, which is to be used for automatic forecasting of time series. Design/methodology/approach: The work uses the algorithm of automatic forecasting of time series implemented in the "forecast" package. The algorithm was used in a loop for different lengths of the time series to determine the best length of the series. The minimal RMSE value in the training set and in the test set were considered as optimality criteria. Findings: It is shown that the best time series length is 60 weeks in the considered case. Originality/value: The procedure for selecting the best time window length for forecasting demand for products in distribution network.

    Opis:
    Purpose: The purpose of this paper is to analyze material flow from the perspective of a logistics operator operating in a distribution network at Material Decoupling Point (MDP). This analysis will focus on classifying the flowing products into the appropriate groups in terms of their sales characteristics, release volume and the value of the coefficient of variation. This analysis will also involve product classification in terms of forecast accuracy. Design/methodology/approach: Main method used for the research focuses on analyzing one of distribution network. Analyze considered examination of material flow and tests of forecast tool to improve operational issues. Findings: Logistics operator is able to forecasting demand of products in distribution network. It is interesting area of research developing in the future. Originality/value Forecasting is considered here as a kind of development perspective for the operator who currently does not make forecasts. Forecasting implementation could be in these case
