Heuristic optimization of the p-median problem and population re-distribution

This thesis contributes to the heuristic optimization of the p-median problem and Swedish population redistribution.   The p-median model is the most representative model in the location analysis. When facilities are located to a population geographically distributed in Q demand points, the p-median model systematically considers all the demand points such that each demand point will have an effect on the decision of the location. However, a series of questions arise. How do we measure the distances? Does the number of facilities to be located have a strong impact on the result? What scale of the network is suitable? How good is our solution? We have scrutinized a lot of issues like those. The reason why we are interested in those questions is that there are a lot of uncertainties in the solutions. We cannot guarantee our solution is good enough for making decisions. The technique of heuristic optimization is formulated in the thesis.   Swedish population redistribution is examined by a spatio-temporal covariance model. A descriptive analysis is not always enough to describe the moving effects from the neighbouring population. A correlation or a covariance analysis is more explicit to show the tendencies. Similarly, the optimization technique of the parameter estimation is required and is executed in the frame of statistical modeling. 

Social reproduktion i Värmland : Klass, utbildning och livsstil

Social reproduction in Värmland, Sweden This study uses the 2014 SOM-survey of the Swedish region of Värmland (n = 1420) to study the ways in which social reproduction is expressed in a regional setting. Following the sociology of Bourdieu the study presents statistically significant results that highlight that a.) class habitus shapes the type of home one creates for oneself and b.) one’s level of education, and that c.) the orientation towards the ”legitimate” culture is particularly pronounced among those with relatively high volumes of economic and cultural capital and finally that d.) a regional elite is consecrated in the cultural and urban center of the region. Although the sociological explanation to ”why we do what we do” is not the only one, this study shows that it is an important one. Class, expressed as class habitus and volume of economic and cultural capital, continues to shape peoples’ life choices and their orientations in the social world.
