Selection of information - the choice of only qual-ity ones, i. e. essential ones, is a big problem in management decision-making. Implementation of systemic approach i. e. dialectical-network thinking (DNT) can help to deal with it. The paper presents a holistic thinking approach in a case study for the Slovenian parcel postal problem. The volume of parcel flows at the Post of Slovenia between Posts is increasing rapidly and it requires a new design of the postal network. This paper presents a reorganization of parcel services between Postal Logistics Centers and Posts by adding Regional Parcel Centers and Parcel Posts to the network. A case for the area covered by Ljubljana Postal Logistics Center is given, which takes into consideration the sorting out and the retaining of parcels in the Posts, Parcel Posts and Regional Parcel Centers within their individual areas.20082017-06-02 10:35:53Znanstveno delo65984sl
