This paper focuses on modelling and performance evaluation of an Intermodal Freight Transport Terminal (IFTT), the rail-road inland terminal of a leading Italian intermodal logistics company. The IFTT is regarded as a discrete event system and is modelled in a timed Petri net framework. By means of suitable performance indices, we simulate the Petri net model and evaluate the operational performance...
We present a Decision Support System (DSS) for real-time management of railway networks. The DSS employs a mathematical programming approach addressing traffic rescheduling under unexpected disturbances in a mixed-(single- and double-) tracked network. The DSS simulates the network behavior with the mathematical programming model based on the railway topology and constraints, rescheduling the timetable...
Due to their outstanding strain capability, Magnetic Shape Memory actuators are a promising technology for positioning systems. Their wide hysteresis and dependence on temperature require a control system capable to cope with time-varying hysteresis as well as other uncertainties. In this paper, we adopt a modified Prandtl-Ishlinskii operator to capture and compensate by inverse model the hysteresis...
