Färskvaror, automation och framtidenEldh, Philip, Närsten, Olliver January 2019 (has links)
Det finns för närvarande en stark, nationell och internationell, efterfrågan på effektivare bruk av resurser och färskvaror, bland annat från svensk dagligvaruhandel, den svenska regeringen och FN. Naturvårdsverket visar samtidigt att i Sverige så slängs cirka 1.3 miljoner ton mat årligen och att 40% av detta slängs i konsument och butiksled. Detta till trots att dagligvaruhandeln har automatiserade inköpssystem, så kallade Automatiska Ordersystem (AOS). Med utgångspunkt ur dessa system har författarna undersökt, med hjälp av evidensbaserad managementmetodik, intervjuer och observation, Axfoods AOS, Autoorder (AO) utifrån ett inventory managementperspektiv hur systemets nuläge ser ut samt utvecklat en prototyp-modell. Dynamiken av systemet låg fokus, utifrån teoretisk applicering från nutida forskning inom Inventory management. Studien resulterade i teoretisk prototyp som ämnar att bidra till underlag för vidare forskning av AOS. / There’s currently a strong demand, national and international, for a more effective use of resources and perishable goods, among those behind this demand is the Swedish government, the UN and the daily grocery business interest group, Svenskt Näringsliv. At the same time the environmental protection agency in Sweden reports that 1.3 million tons of food are thrown away yearly and that 40% of this originates from the end consumer and the daily grocery business. This problem occurs even though the daily grocery business operates with automated ordering systems (AOS). With this as a starting point the authors have, using evidence-based management methods, interviews and observations, studied the current stat of the Swedish grocery chain Axfood’s AOS, called Autoorder (AO) from an inventory management-based perspective. This resulted in a simple prototype model, where the dynamic modelling of inventory management took center, to act as a foundation for future research within AOS.

Makroekonomiska faktorers påverkan på svenskt och amerikanskt aktieindex : En studie om hur olika makroekonomiska variabler påverkar aktiemarknaden mellan 1970–2021 / Macroeconomic determinants of Swedish and American stock index : A study about various macroeconomic variables effects the stock market between 1970-2021Brolin, Magnus, Olsson, David January 2022 (has links)
Under ekonomiska konjunkturcykler är sambandet mellan grundläggande makroekonomiska variabler och aktiemarknadens avkastning högst intressant att undersöka. Syftet med denna uppsats är att undersöka hur aktiepriser på den svenska- och amerikanska aktiemarknaden påverkas av relevanta makroekonomiska faktorer under tidsperioden 1970–2021. Genom ko-integrationstest, Vector Error Correction modeller och kausalitetstest på årsdata finner vi signifikanta resultat för att den svenska aktiemarknaden divergerar från jämvikt av en chock i penningmängd. För den amerikanska aktiemarknaden finner vi fler signifikanta resultat och att en chock i statsskulden skapar en divergerande effekt i fjärde laggen men en konvergerande effekt i andra. För att fördjupa undersökningen genomförs en bivariat analys för att undersöka hur aktiepriser påverkas av BNP som en indikation på ekonomisk tillväxt och även hur aktiepriser påverkas av lång och kort ränta som en konjunkturindikator. Resultaten varierar för Sverige och USA. Det kausala sambandet mellan aktiepris och BNP visar att aktiepris påverkar BNP för Sverige. För USA finner vi däremot inga signifikanta resultat gällande det kausala sambandet. För sambandet mellan amerikanskt aktiepris mot kort och lång ränta så visade det sig att kort ränta orkar divergens mot jämvikt för aktiemarknaden. För Sverige påvisade resultaten att kort ränta orsakar konvergens och lång ränta divergens vid en chock i aktiemarknaden. / During economic cycles, the relationship between fundamental macroeconomic variables and stock market returns is highly interesting to examine. The purpose of this thesis is to investigate how share prices in the Swedish and American stock markets are affected by relevant macroeconomic factors during the period 1970–2021. Through co-integration tests, Vector Error Correction models and causality tests on annual data, we find significant results for the Swedish stock market to diverge from equilibrium by a shock in the money supply. For the US stock market, we find more significant variables and a result that a shock in the central government debt creates a divergent effect in the fourth layer but a converging effect in the second. To deepen the survey, a bivariate analysis is carried out to examine how share prices are affected by GDP as an indication of economic growth and how share prices are affected by long-term and short-term interest rates as a business cycle indicator. The results vary for Sweden and the USA. The causal relationship between share price and GDP shows that share price affects GDP for Sweden. For the United States, however, we find no significant results regarding the causal relationship. For the relationship between the US share price against short and long interest rates, it turned out that short interest rates can withstand divergence towards equilibrium for the stock market. For Sweden, the results showed that short-term interest rates cause convergence and long-term interest rate divergence in the event of a shock in the stock market.
