Evaluering av diskret händelsesimulering för produktionssystem : En jämförelsestudie av FACTS Analyzer och Plant Simulation i undervisande sammanhang / Evaluation of discrete-event simulation for production systems : A comparative study of FACTS Analyzer and Plant Simulation in an educational context

Ahl, Victor, Klasén, Erik January 2024 (has links)
The use of simulation programs in production environments is crucial due to the many advantages they offer, such as facilitating calculations of production capacity, cycle times, and optimal buffer sizes. These tools allow for the simulation of various scenarios and cost-effective testing of different strategies, making them invaluable for companies striving to improve production and performance.  The purpose of this work is to conduct a case study using FACTS Analyzer and then compare the results with another simulation software that supports 3D simulations. By conducting the same case study in both programs, we can draw conclusions about the factors companies should consider when acquiring simulation software. The data will be collected through qualitative methods such as observations and interviews, complemented by quantitative methods through experiments within the case study. The results show that FACTS Analyzer and the chosen program Plant Simulation serve different purposes but within similar areas. FACTS Analyzer offers a simple and effective 2D simulation experience that is particularly useful for students and companies planning production. On the other hand, Plant Simulation provides extensive capabilities to model everything from individual production lines to entire facilities in a clear 3D environment, making it easier for people without in-depth knowledge of the field to understand the simulations. In conclusion, the study shows that both programs can complement each other by offering unique capabilities in different domains, providing companies with a competitive advantage by optimizing their production and planning processes.

From Snow White to Frozen : An evaluation of popular gender representation indicators applied to Disney’s princess films / Från Snövit till Frost : En utvärdering av populära könsrepresentations-indikatorer tillämpade på Disneys prinsessfilmer

Nyh, Johan January 2015 (has links)
Simple content analysis methods, such as the Bechdel test and measuring percentage of female talk time or characters, have seen a surge of attention from mainstream media and in social media the last couple of years. Underlying assumptions are generally shared with the gender role socialization model and consequently, an importance is stated, due to a high degree to which impressions from media shape in particular young children’s identification processes. For young girls, the Disney Princesses franchise (with Frozen included) stands out as the number one player commercially as well as in customer awareness. The vertical lineup of Disney princesses spans from the passive and domestic working Snow White in 1937 to independent and super-power wielding princess Elsa in 2013, which makes the line of films an optimal test subject in evaluating above-mentioned simple content analysis methods. As a control, a meta-study has been conducted on previous academic studies on the same range of films. The sampled research, within fields spanning from qualitative content analysis and semiotics to coded content analysis, all come to the same conclusions regarding the general changes over time in representations of female characters. The objective of this thesis is to answer whether or not there is a correlation between these changes and those indicated by the simple content analysis methods, i.e. whether or not the simple popular methods are in general coherence with the more intricate academic methods. / <p>Betyg VG (skala IG-VG)</p>
