Educational objectives The course objective is to provide basic knowledge for the management of a production system as a whole, in order to optimize its performance in terms of cost reduction and service level fulfillment.
The main knowledge gained will be:
theoretical knowledge on materials management, such as inventory control policies for items with independent demand
theoretical knowledge related to material with dependent demand, such as heuristic for lot sizing, forecasting, and basic concepts of Material Requirement Planning

The main skills are:
application of forecasting techniques on historical data for the calculation of future requirements
Ability of develop the Sales and Operations Plan (S & OP)
Ability to develop Master Production Schedule (MPS)
Ability to optimize order quantities and reorder points
Ability to optimize the time interval between orders and the order-up-to levels
Prerequisites In order to understand and to apply most of the techniques described in the course it is essential the knowledge of the following topics:
- Integral, indefinite integrals, multi-variable functions, maximum and minimum bounded
- Probability density functions, basic concepts of statistics.
It is also important to have succesfully taken an exam about Facilities Planning.
Teaching methods The course is organized as follows:
- Theoretical lessons on all topics of the program
- Classroom exercises consisiting in solving practical problems
The exercises are held during class time, and immediately follow the theoretical lesson to which they refer
Other information Attendance is not comulsory but strongly adviced.
Learning verification modality The exam consists of a written exam.
The written exam consists in an exercise in which the student has to solve a problem related to subject as demand forecasting, inventory control, MRP. The exercise aim is to determine the ability to correctly apply the theoretical knowledge, the understanding of the issues proposed, and the concentration ability needed to perform correctly the calculation needed to solve the problem. The test duration is approximately 1h 30m
The oral exam consists of 3 questions designed to ascertain the level of knowledge and understanding of the issues on theoretical and methodological aspects of the program. The duration of the test is about 30 min.

Learning verification modality The exam includes an oral test which consists of a discussion lasting about 45 minutes aimed at ascertaining the level of knowledge and understanding reached by the student on the theoretical and methodological contents indicated in the program. The oral exam will also allow to verify the student's communication skills with language properties and autonomous organization of the exhibition on the same theoretical topics.
Extended program Quality control, the framework in the European Union, history and evolution of quality, the quality manual, accreditation and certification, statistical tools for quality control, reliability, traceability of measurements, legal responsibility from defective product, accelerated tests, innovative diagnostic techniques for quality control: non-contact temperature measurements, stress measurement by thermoelasticity, strain measurement by Digital Imaging Correlation, vibrometry and anemometry laser Doppler. The main advantages, metrological characteristics, measurement problems and causes of uncertainty are discussed. Application examples are also provided.
