The aim of this paper is to find an algorithm to establish and maintain a virtual enclosure around a mobile unit. The area may take any form and should be scalable up to and including national borders. The enclosure is managed on the mobile unit. The target system is Android. Smartphones, tablets and more recently, cameras is examples of mobile units.

Never before have so many moved so frequently as now. Mobility lies at the centre for the concern ofstates, business and technological development. Some even claim that we are witnessing a mobility turn inthe social sciences. However, as the capacity to move has increased so too has the control and surveillanceof mobility become more extensive. Since September 11, 2001 security has been the defining paradigm fora variety for actors.

The market for security is one filled with great opportunities. The security services companies are numerous and diverse, the Swedish market is dominated by two large companies: Securitas Bevakning AB and Falck Security AB. In this study we have focused on the bigger of the two, Securitas. This report describes and analysis the security service branch and its surroundings in an involved manner. The target group of the result is mainly people within the security branch.

 Det statistiska kvalitetsverktyget Statistisk Processtyrning, SPS, introducerades på BT Products AB i Mjölby utifrån en specifik implementeringsprocess. Introduktionen utfördes i en målningsprocess och genom detta arbete kunde aktuell process utvärderas och orsaker bakom eventuell urskiljbar variation eftersökas. I gällande process målas gods till eldrivna truckar svarta genom elektrostatisk pulvermålning, där eftersträvad färgskikttjocklek är 70 µm. Målningen utförs automatiserat av fyra robotar och för att erhålla kunskap om processens uppförande studerades och analyserades utfallet statistiskt utifrån en bestämd kvalitetsindikator, färgskikttjockleken. Data samlades in utifrån denna indikator genom kontinuerlig mätning på utvalt objekt och med hjälp av en mätmall för att erhålla jämförbara observationer.
