Two constructions of continua: inverse limits and compactifications
Tina Sovič, 2013, doktorska disertacija

Opis: In the thesis we talk about two different constructions of continua. First we present the generalized inverse limits, with help of which we construct Wazewski's universal dendrite. What follows is a description of the compactifications of a ray and the presentation of results about their span. The first chapter will be an introduction to the continuum theory trough interesting examples, as sin(1/x)-continuum, Hilbert cube, Brouwer-Janiszewski-Knaster continuum and pseudoarc. We will present some of their properties, among which irreducibility, smoothness and span zero are the most important ones for us. In the continuation we intend to present some various constructions of continua. The main focus will be on the generalized inverse limits and compactifications of rays, which will also be a central part of the thesis. In this chapter, we also study inverse limits in the category of compact Hausdorff spaces with upper semi-continuous functions. We show that the inverse limits with upper semi-continuous bonding functions, together with the projections are weak inverse limits in this category. The following two are the most important chapters in the thesis. The first is a detailed description of a construction of the family of upper semi-continuous functions f, such that the inverse limit of the inverse sequence of unit intervals and f, as the only bonding function, is homeomorphic to Wazewski's universal dendrite for each of it. Among other results we will also give a complete characterization of comb-functions, for which the inverse limits of the type described above are dendrites. The next important chapter will be about compactifications of rays. In the first part of this chapter we will use compactifications to prove that for each continuum Y there is an irreducible smooth continuum that contains a topological copy of Y. The second part presents the main results of this chapter; i.e. the span of a compactification of a ray with a remainder that has a span zero is also zero. In the proofs of this chapter we will help ourselves with a discretization of span.

UPORABNOST ZASNOVE UPRAVLJANJA BLAGOVNIH SKUPIN V MARKETINGU
Tadej Gosak, 2015, magistrsko delo

Opis: Zaostrene gospodarske razmere v zadnjih letih občutijo v domala vseh gospodarskih panogah. Padec potrošnje in manjša kupna moč se v proizvodnih podjetjih kažeta v manjši prodaji, viških proizvodnih zmogljivosti in nižjih prodajnih cenah. Podjetja s težavo odplačujejo kredite za investicije iz časa konjunkture in imajo potrebe po dezinvestiranju. Soočajo se tudi s pomanjkanjem likvidnih sredstev za tekoče poslovanje. Z obstoječimi programi ustvarjajo premalo dodane vrednosti, njihov fiksni stroški so previsoki. S podobnimi težavami se soočajo tudi v trgovskih organizacijah. Manjša kupna moč se kaže v manjših izdatkih gospodinjstev in spremenjenih nakupnih navadah. Ob ekonomskih učinkih, ki so posledice recesije, pa je kriza primeren trenutek, da podjetja v svoje delovanje uvedejo nove prakse poslovanja, s katerimi želijo izboljšati poslovno učinkovitost in ta način delovanja prenesti v nenehno izboljševanje poslovnih procesov. Za učinkovitejše poslovanje ki se bolje osredotoča na potrošnika, je praksa razvila upravljavski koncept t.i. category managementa, ki temelji na načrtnem in sistematičnem upravljanju sortimenta. Category management v poslovanje uvaja model kooperacije in poudarja sodelovanje med trgovsko in proizvodno organizacijo. Obe sta v tem modelu zavezani k projektnemu sodelovanju, katerega cilj je povečanje prodaje in dobička. Magistrska naloga bo obravnavala teoretične vidike category managementa, ki jih bomo nadgradili z raziskavo njegovega vpliva na obseg prodaje, vključili pa bomo tudi nekatere primere iz prakse.
