INTRODUCTION

TheReturn to main menuThe Statistical Process Control is a mathematical analysis method to understand and forecast the behaviour of “critical to quality” dimensions. The gauss chart, built using a set of values acquired over times for each dimension (sampling), represent the probability distribution of success results, compared to the project specifications (target value, lower limit, upper limit). Each value contained in the set is called survey. The central SPC is a web platform were all the sets of values of each critical measure (for each production plant) are collected, analyzed and shown in visual web user interfaces.
