Only 9 CFU course:
Kelton, Law, Simulation modeling and analysis, McGraw Hill.
Kelton, Law, Sadowsky, Simulation with Arena, McGraw Hill
To understand and assess the coherence between the production process and the product type, identifying the critical factors for the design and management of production facilities. Knowing how to define a technical performance measurement system for a manufacturing plant, to be used for diagnostic purposes. Having Knowledge of the main maintenance philosophies, their strengths and weaknesses, applicability and economic optimization. Developing skills for Reliability Centered Mainenance and Total Productive Maintenance. Being able to model the operations with tools such as Queuing Theory, the Montecarlo method
The 9 CFU course, or the 3 CFU laboratory associated, develop the skill to employ the discrete event stochastic simulation, in order to develop design and re-engineering solutions for the production systems and its management.
The teaching aims for the students enrolled in Environmental Engineering are partially different: they must learn how to approach mechanical aspect of plants, acquiring basic knowledge in order to correctly manage, besides the sanitary process aspects, even plant engineering assets , and the mechanical failures by which they are affected. They must know how to select the appropriate maintenance philosophy for the different assets and different use, and how to manage it using the proper information technology support.
"Industrial Statistic" or "Probability and statistic"
Frontal lectures, training in IT laboratory or by BYOD based on industrial data logs analysis, discussion of cases.
For 9 CFU course: lectures immediately followed by training in IT laboratory or by means of BYOD
Examination dates upon request
Type of Assessment
For 9 CFU course, or for the 6 CFU together with 3 CFU laboratory:
Development of a group project work (no more than 5 students), using the scheduled hours for "industrial plant simulation laboratory".
The oral examination will be based on the discussion of the project work developed, its theoretical bases, the methodologies employed.
The project work stems from the analysis of a log file produced by plan automation software, like MES records or SCADA logs, in order to diagnose strength and weakness of the functioning. The students have to propose solutions able to improve performance, assessed by means of a digital simulation model, validated AS IS, and compared with the TO BE solution. The group produces a technical report and an executive summary that is presented and discussed during the oral examination.
The mark is given taking into account the scientific bases, the assessment, methodologies, bibliographic references and results, weighting 80% for quality of the report and of its contents, and 20% for the answers given during the discussion.
