Opis: Enticed by the promise of larger sales and better access to customers, consumer goods compa- nies (CGCs) are increasingly looking to evade traditional retailers and reach their customers directly–with direct-to-customer (DTC) policy. DTC trend has emerged to have major im- pact on logistics operations and distribution channels. It oers significant opportunities for CGCs and wholesale brands to better control their supply chain network by circumventing the middlemen or retailers. However, to do so, CGCs may need to develop their omni-channel strategies and fortify their supply chains parameters, such as fulfillment, inventory flow, and goods distribution. This may give rise to changes in the supply chain network at all strategic, tactical and operational levels. Motivated by recent interests in DTC trend, this master thesis considers the time-evolving supply chain system of an international healthcare company with preordained configuration. The input is bottleneck part of the company’s distribution network and involves 20% ≠ 25% of its total market. A mixed-integer linear programming (MILP) multiperiod optimization model is developed aiming to make tactical decisions for designing the distribution network, or more specifically, for determining the best strategy for distributing the products from manufacturing plant to primary distribution center and/or regional distribution centers and from them to customers. The company has got one manufacturing site (Mfg), one primary distribution center (PDP) and three dierent regional distribution centers (RDPs) worldwide, and the customers can be supplied from dierent plants with various transportation modes on dierent costs and lead times. The company’s motivation is to investigate the possibility of reduction in distribution costs by in-time supplying most of their demand directly from the plants. The model selects the best option for each customer by making trade-os among criteria involving distribution costs and lead times. Due to the seasonal variability and to account the market fluctuability, the model considers the full time horizon of one year. The model is analyzed and developed step by step, and its functionality is demonstrated by conducting experiments on the distribution network from our case study. In addition, the case study distribution network topology is utilized to create random instances with random parameters and the model is also evaluated on these instances. The computational experiments on instances show that the model finds good quality solutions, and demonstrate that significant cost reduction and modality improvement can be achieved in the distribution network. Using one-year actual data, it has been shown that the ratio of direct shipments could substantially improve. However, there may be many factors that can impact the results, such as short-term decisions at operational level (like scheduling) as well as demand fluctuability, taxes, business rules etc. Based on the results and managerial considerations, some possible extensions and final recommendations for distribution chain are oered. Furthermore, an extensive sensitivity analysis is conducted to show the eect of the model’s parameters on its performance. The sensitivity analysis employs a set of data from our case study and randomly generated data to highlight certain features of the model and provide some insights regarding its behaviour.

Opis: V magistrski nalogi sem predstavila poezijo Lili Novy, ki je bila izdana v dveh pesniških zbirkah Temna vrata (1941) in Oboki (1959) ter v pesniški zbirki Črepinje in druge pesmi (2005), v kateri so izbrane pesmi napisane v nemškem jeziku in prevedene v slovenski jezik. V nalogi sem se osredotočila na motive časa, minevanja in starosti. Prva dva dela temeljita na pregledu in povzemanju teoretskih in literarno teoretskih besedil. V prvem delu sem predstavila nekatere teorije, ki so skušale razložiti pojem časa. V drugem delu sem predstavila recepcijo poezije Lili Novy, ki je bila ob izidu njenih dveh pesniških zbirk skromna in še danes ni veliko raziskovalcev in raziskovalk, ki bi se z njeno poezijo ukvarjali. Kljub temu, da poeziji priznavajo kvaliteto, še vedno ni sprejeta v slovenski literarni kanon. V tretjem delu sem analizirala poezijo s fokusom na motivih časa in minevanja, ugotavljala sem, kako se lirski subjekt sooča s tem, da čas mineva in s tem prinaša spremembe, tako kolektivno kot v intimnem doživljanju posameznika.

Opis: A consequence of Grice’s maxims is that the proposition which is asserted is the most informative one in the set of relevant propositions which the speaker believes to be true (cf. Grice 1967). This consequence contradicts in reality in the case there are two relevant propositions which are both more informative than the assertion but contradict each other. This contradiction is the so-called “symmetry problem” in the literature. This thesis introduces the symmetry problem and disscusses two approaches to dissolve it, in which the second one develops from the first one.

Opis: Waste management is a global problem, as waste production continues to rise, and the methods used today, such as landfilling and incineration, can cause many environmental issues. Waste gasification, among other technologies, is a promising alternative since waste is turned into useful energy resources and reduces emissions with the formation of syngas. Thus, this thesis investigated the potential of waste gasification systems in sustainable waste management and circular economy. Focusing on its energy and economic potential, modeling methods were used to recreate real-world systems, with the goal of properly estimating the true sustainability potential of the waste gasification systems. Biomass gasification was evaluated through thorough thermodynamics and economic analysis. Although the initial calculations failed to provide positive results by showing the energy of 54 MJ, instead of the expected energy release, further analysis with the optimized conditions and different assumptions, provided more accurate results. By increasing the share of oxidized CO from 10% to 25%, and reducing the wet material from 35% to 10%, total released heat was estimated to be −148.9 MJ. With the right assumptions, the gasification process was proved to provide good energy values necessary for the sustainability of such a process. Additionally, the financial analysis produced a high Net Present Value (NPV) of EUR 3,434,411.46, Internal Rate of Return (IRR) of 21.81%, and a short payback period (PP) of 4.48 years, hence proving the strong economic potential and financial strength of such technology. Therefore, biomass waste gasification was concluded to be a positive investment opportunity with valuable long-term economic benefits, while still providing good energy balance.
