Lezioni della classe erogate in presenza
It is suggested for students to have attended a basic course on mathematics and a basic course on statistics before this course.
The scope of this course is to allow participants a thorough exploration of business analytics and of how computational modelling can be combined with big data to achieve given industry goals. In a well known communication to the European Parliament on 2 July 2014, the European Community evidenced the need of training a generation of managers who know how to combine information derived from data into models to support decisions. In fact, in recent years, the data driven revolution is changing the way in which institutions and corporations make decisions. We are heading towards industry 4.0. The great availability of data, the increased computing and information technology capabilities are creating new jobs and changing the way in which companies operate. The February 2018 report of the UK Government Office for Science highlights that computational modelling is a source of competitive advantage for corporations. In the first part of the course, participants are exposed to the fundamental theoretical and methodological basis, analyzing relevant quantitative and mathematical methods. In the second part, students are exposed to industry case studies. With the participation of data scientists and experts coming from the industry participants discover how innovative methods based on big data and information technology have allowed to solve modern industrial problems.
- Computational Modelling: Introductory Principles.
- Formulation of quantitative models via Linear Programs.
- The symplex method, Duality.
- Sensitivity Analysis.
- Network Type Problems.
- Big Data and Lasso: The Dantzig Selector.
- Industry 4.0 and Descriptive Analytics: Business Case studies.
These case studies are discussed and solved in the presence of guest lecturers from Siemens and from the involved partner companies.
- Formulate a computational model to solve business and management problems.
- Appreciate the principles and the solution algorithms of linear programs at the basis of dedicated software for their application.
- Distinguish the wide range of business problems whose solution is supported by computational models.
- Recognize the challenges posed to quantitative methods by large dimensionality and big data and identify the corresponding technological solutions.
- Organize information to build a quantitative model in line with the input posed.
- Translate a business problem into a corresponding computational modelling frame.
- Use dedicated software in order to obtain quantitative information.
- Interpret solutions derived from implementing the chosen model in order to make optimal decisions.
- Analyze quantitative models with sensitivity analysis tools to obtain "managerial insights".
- Face-to-face lectures
- Guest speaker's talks (in class or in distance)
- Case studies /Incidents (traditional, online)
The course makes use of a combination of teaching techniques. Face-to-face lectures are used for the sessions in which methodological and theoretical parts of the paper are proposed and discussed.
- In these sessions students are assisted in identifying the quantitative model, in implementing the model through dedicated software and in performing sensitivity analysis.
- In the second part of the course, students are exposed to the solution of industry case studies presented in a triplet of lectures. After the exposition by the experts of the industrial problem, participants are introduced to the methods of solution and are guided in critically discussing the results, the methodologies adopted and in identifying weaknesses and remaining open questions.
Assessment, both for attending and non-attending students, is based entirely on a written exam organized as follows. For the first part of the course there is problems to solve divided into open-ended numerical questions and multiple-choice questions. For the second part of the course there are questions concerning the methodological aspects of the illustrated case studies. Students have the possibility to take the exam either through a partial (50% of the grade) and a final example (50% of the grade) or through a general written exam (100% of the grade). The general written exam is the union of the partial and the final.
