Obiettivi dell'insegnamento
Nowadays, an impressive amount of data can be collected in real industrial scenarios (Industry 4.0). The course presents a set of quantitative tools and methods for managing, modeling, monitoring data in industrial and business scenarios.  Specific attention is given to quality data, i.e., all the key indicators of products and processes which play a relevant role in creating added value for the company. 
 
After successfully completing the course, students should be able to do the following:
 
1. Understand the philosophy and basic concepts of quality data modelling, monitoring and improvement.
2. Extract relevant information from complex, high-dimensional data
3. Identify models to predict the expected pattern of quality and performance indicators
4. Design and use appropriate tools to design and manage data in industrial and service scenarios.
 

The course fits into the overall program curriculum pursuing some of the defined general learning goals. In particular, the course contributes to the development of the following capabilities:

  • Understand context, functions, processes in a business and industrial environment and the impact of those factors on business performance

  • Design solutions applying a scientific and engineering approach (Analysis, Learning, Reasoning, and Modeling capability deriving from a solid and rigorous multidisciplinary background) to face problems and opportunities in a business and industrial environment

  • Develop new ideas and solutions in business and industrial scenarios evolving over time


Risultati di apprendimento attesi

Lectures will provide the basic tools to understand functions and processes, using appropriate quantitative tools for data analysis. 
Recitations in computer labs will show how the learned tools can be effectively used to design new solutions using a scientific approach to face the problems at hand (applying knowledge and understanding). 

The lab project will foster an additional insight to develop new ideas and solutions in business and industrial scenarios (making judgements and learning skills). 


Argomenti trattati
  1. Quality engineering & Industry 4.0: data analysis as a basic tool for modeling, monitoring, control and improve.
  2. Approaches for quality data modeling: 
    • Standard assumptions and related tests; 
    • Modeling patterns via linear models; 
    • Modeling autocorrelated data via time series analysis; 
    • Modeling multivariate data and dimensional reduction
    • Modeling survey data: Categorical and ordinal data
  3. Quality monitoring of continuous variables
    • Traditional statistical process control (SPC)  for the mean and the variance
    • SPC for autocorrelated data: Problems of traditional control charts for autocorrelated data; Model based and model-free approaches for quality control of autocorrelated data.
    • Multivariate SPC: Design and managing multivariate control chart for the mean and the variance.
    • Toward zero-defect manufacturing: process quality and product specifications. Capability analysis. Univariate and multivariate control charts for small shifts (EWMA, CUSUM).
  4. Quality monitoring of discrete, categorical and ordinal data (for management engineering only).
    • SPC for Binomial and multinomial data
    • Logistic and ordinal regression
  5. Acceptance Sampling and Quality control – Lot-by-lot acceptance plans for univariate and multivariate data (for management engineering only - hints)
  6. Quality Improvement – The role of improvement in the six-sigma roadmap. Quality improvement via empirical model building (for management engineering only- hints).

Prerequisiti

A five-credit course in Statistics is required.

Students should mainly know:

- basics of statistical distributions (normal, poisson, binomial. Chi-square, Chi)

- Confidence intervals and Hypothesis tests

 A short recap will be provided in the first few classes of the course.


Modalità di valutazione

Written Exam 

The written exam is aimed at verifying if the students have suucessfully acquired knowledge of the basic tools to understand functions and processes. One of the test in the written exam is aimed at testing if students are able to use the newly acquired knowldge to design solutions for qualitative data analysis, using the data and information at hand.

The final mark in the written exam can range from "fail" to "30".

Project work

An optional (highly suggested) project work is possible. In this case the students will be facing a real industrial problems using complex data sets to be analysed and monitored. The project work allows students to enhance their skills to develop new ideas and solutions in real industrial scenarios.

Oral exam

The oral exam is optional and can be undertaken only if the written exam is sufficient (mark higher than >18). A maximum increase of the final grade of 3/30 can be achieved with the oral exam
