This thesis aims to describe and analyze various Statistical Quality Control techniques and
their application in a manufacturing process with real data. This will be done after an initial
statistical analysis that will allow us to group and interpret the factors which influence the
quality of gasoline produced at the refinery of a Greek company in Thessaloniki. Gasoline is a light liquid, volatile and inflammable and also one of the main and most
useful petroleum derivatives, mainly extracted from its fractional distillation. There are several factors which, during the refining, can influence the quality of the
outgoing product (gasoline), others to a small and others to a greater extent. In this thesis are
presented, analyzed and interpreted the variables that are directly linked to factors that can
affect the quality of gasoline produced during the production process. Various performance
indices will also be calculated and appropriate control charts will be constructed that will help
us come to conclusions about how to improve the final product.
