Uvajanje računalniško podprte proizvodnjeUroš Trupej
, 2013, undergraduate thesis
Abstract: V svoji diplomski nalogi sem se osredotočil na uvajanje računalniško podprte proizvodnje in kakšne prednosti prinaša. Računalniško podprta proizvodnja združuje moderno računalniško tehnologijo z naprednimi obdelovalnimi stroji in povezavo z informacijskim sistemom, kjer je človek še vedno vodilo napredka. Na teoretičnem primeru sem prikazal kakšne spremembe mora neko podjetje opravit in kakšne pogoje mora zadostiti, da lahko uvede računalniško podprto proizvodnjo.

Abstract: Since the transport causes about 26% of global CO2 emissions, the need to reduce greenhouse gas emissions (GHG) is becoming increasingly necessary. To achieve this objective, several approaches were adopted, like for example the employment of alternative sustainable technologies, or the enforcement of changes in driving skills. In contrast with this kind of approaches, an interesting approach is to reduce the vehicle miles of travel (VMT). In this paper, the concept of VMT reduction based on a heuristic optimization approach is introduced. The suitability of this concept has been tested for the School Bus Routing Problem (SBRP). Working mechanisms of the adopted heuristic optimization algorithms are briefly explained. As can be seen from the results, the optimization of bus stops, bus routes and driving schedules can significantly reduce the amount of VMT and consequently the amount of CO2 emissions.
Keywords: transport planning, environment, heuristic optimization approach, school bus routing problem

Abstract: Logistics forwarder, as organizer and planner of coordination and integration of all the transport and logistics chains elements, uses adequate ways and methods in the process of planning and decision-making. One of these methods analysed in this paper, which could be used in optimisation of transport and logistics processes and activities of logistics forwarder, is the multicriteria optimisation method. Using that method, in this paper is suggested model of multicriteria optimisation of logistics forwarder activities. The suggested model of optimisation is justified in keeping with method principles of multicriteria optimization, which is included in operation research methods and it represents the process of multicriteria optimization of variants. Among many different processes of multicriteria optimization, PROMETHEE (Preference Ranking OrganizationMethod for Enrichment Evaluations) and Promcalc& Gaia V. 3.2., computer program of multicriteria programming, which is based on the mentioned process, were used.
