Purpose: The purpose of this thesis is to develop a simulation model that represents the S-train network. The model will then be analysed in order to improve the regularity. We will then present a locally optimized proposal on the placement of the buffer time for every train line. Delimitation: This report intends only to analyse a ”normal day” during rush hour. We will ignore unexpected course of

This master thesis studies a two-echelon distribution system for perishable items with two non identical retailers. Each location is managed following a standard continuous (R, Q) ordering policy. The demand occurs solely at the retailers and follows independent Poisson processes. Customers are backordered when the retailer is out of stock. The items are considered as fixed lifetime perishables. W

Three standard approaches of finding Value at Risk; age weighted historical simulation, volatility weighted historical simulation and t – distribution were compared with Value –at – Risk calculated using generalized extreme value theory during the period 2000 to 2010 to see which approach that would give the most accurate forecast of actual losses during the two volatile times within the time fram
This study aims to examine what it is that makes that cyclist do not follow the traffic rules as much as motorists. It also aims to try to find different aspects of cyclists and motorists which can influence their behavior in traffic. In this study it has been used a qualitative research method and focus groups interviews. The theoretical framework is based on Ajzens, Theory of planned behavior (T
Seagrass fragmentation is a process that results in changes to landscape features and can seriously impact certain fauna groups. To understand how habitat fragmentation and patch size influences predator-prey interaction has become an important task for researches worldwide, in order to visualize how this process affects key species in this environment. We performed laboratory experiments to inves
In the ongoing joint venture between Ericsson and ST Microelectronics, EMP spend data needed to be extracted, consolidated and analyzed to support the ongoing joint venture. Provide an understanding what spend analysis is and how it can support the business and operations in the company. Purpose: The purpose with this master thesis was to create a foundation of spend analysis knowledge at the comp
Med den lavinartade ökningen av Internetanvändning de senaste tio åren har det även kommit nya sätt att utföra telefonsamtal på. VoIP möjliggör telefontrafik över nätverk och integrerar på så sätt telefontrafiken och datatrafiken till ett och samma nät. Vi har undersökt vilka hinder som kan tänkas ligga i vägen för en övergång till VoIP inom Sveriges kommuner. Vi har även lyft fram vilken kunskap
This Master Thesis was carried out at Ecolean Development AB, which is a subsidiary to Ecolean AB.
