The article deals with the possible application of the Solver optimization module to solving the single-circuit transport problems. First, the article describes the single-circuit transport problems and the optimization module Solver itself. Using the specific model example of beer distribution, the author demonstrates the algorithm which may be applied to solving single-circuit transport problems by means of Solver. The travel route designed by Solver is then compared with the originally proposed route. The values being compared include the total length of travel routes created and the associated variable costs spent on serving customers and also route design time. Thus, using the practical example of beer distribution, the manuscript has demonstrated the algorithm which is used for addressing the single-circuit transport problems. Nonetheless, possible application of the Solver tool is not limited to seeking a solution to the travelling salesman problem only. It can also be implemented even to discussing the multi-circuit transport problems with various confinements.
This paper is aimed to compare two regulations concerned with the issue of determining the amount of a provable loss or, newly, a compensation, i.e. Government Decree No. 493/2004 Sb., regulating the provable loss in the public line transport and specifying the method of the exercise of the professional government supervision in the road transport over funding the traffic services, and Regulation No. 296/2010 Sb. on the procedures for establishing the financial model and setting the maximum amount of the compensation. Both regulations suggest the different methodology for determining the amount of compensation in a transport company for the accounting period. The goal is to analyse which methodology encourages the explanatory power of individual items of economically substantiated costs and revenues and whether it has a consistent influence on the final value of compensation. The question is raised of whether we can achieve the same or at least a similar amount of compensation if both methodologies of the provable loss or compensation calculation are applied in the municipal bus transport.
Abstract:The actual task is to research QoS (Quality of Service) instruments in order to improve existing and develop new methods. This paper presents the modified method of double QoS, which differs from standard one by application of multi-level traffic analysis by user groups, types of traffic and priorities. The efficiency of the proposed method is proved experimentally on routers with the Mikrotik operating system by means of local computer network simulation, based on virtual machines. The experiments were conducted with generated multitraffic with a uniform distribution for Packet Size and Internet Departure Time parameters. Compared results of router work with standard and modified methods. Using the proposed method allows reducing the number of dropped packets by simply configuring the router system tools and thus improving the quality of user service.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
