MVE145 - Statistical quality control, 7,5hp - Sp2, 2007/2008


Product quality is fundamental for every company. Poor quality can
cause warranty costs and liability claims and in worst case and this
can in worst case jeopardize the future of the company. It is
therefore very important to secure the quality and maintain it at a
high level.

Product design is essential for the customer impression of product
quality. Reliability, serviceability and usability are fundamental
characteristics of high designed quality. Robust design assures that
the product can function in different environments, used by different

Even if the product is well designed the production process must be
able to deliver the designed products, at least within tolerances,
but preferable on target with minimum variance.

This course is about produced quality.

The main goal of the course is to understand variation and how to manage different types of variation.
Variation can come from chance causes, systematic causes  or measurement errors. Data can be 
univariate, multivariate, independent  or dependent. Data can be discrete or continuous and can come
from many different distributions.
