ACOUSTICS AND AMBIENT LIGHTING TECHNIQUE
(objectives)
The educational objectives consist in acquiring the physical and psycho-physical basic concepts underlying sound and light perception mechanisms, in the knowledge of acoustical and photometric quantities used in the two areas, of the measuring instruments, of the sound propagation in enclosures and open spaces, of the main types of artificial light sources and of daylighting, of sound-absorbing materials and sound insulation. This represents the basis for the design of the acoustical and luminous environment, both by using simplified calculation methods, and by resorting to the use of dedicated software.

INDUSTRIAL PRODUCTION MANAGEMENT
(objectives)
This course is aimed at providing the basic methodological tools required for production planning and control in manufacturing systems. Specific methods used in make to stock, assemble to order, make to order, and engineering to order are analyzed, also discussing the differences between push and pull production systems. The course follows the traditional hierarchical approach including aggregate production and capacity planning, master production scheduling, materials and manufacturing resources requirements planning (MRP and CRP techniques), order release planning and job scheduling. furthermore, techniques for demand forecasting and implementation of just in time lean manufacturing systems are presented. The course also provides tools to estimate the performances of manufacturing systems, i.e. the links between work in process, throughput and cycle time, including variability effects and lot sizing decisions. finally, production planning decisions are put in perspective with strategic decisions, with capacity planning issues and with inventory management problems.
