Additional costs are the costs of rejected customers which are costs associated with deciding customers to leave the post office. Aim of this article to indicate the methodology of costs allocation of queuing system of post office and display the costs calculation method of rejected customers.

    (University of Zilina, 2019) Harantová, Veronika; Kalašová, Alica; Čulík, Kristián; Otahálová, Zuzana
    A high-quality network is currently a prerequisite for sustainable transport systems. The sharp increase in automobile traffic has resulted in increased transport problems. The most serious transport problems include traffic infrastructure congestion, increased accident risk and of course environmental impact. Daily mobility and securing the transport of goods is one of the key transport objectives. The most critical point of the road network is the intersection. Therefore, great emphasis is placed on the vehicle to pass smoothly and safely when passing through this place. In this paper an analysis of the current status of the selected roundabout is created. Based on the survey it is proposed three solutions to improve the traffic conditions of the intersection. Aimsun micro-simulation was also used to create solutions.
