A mixed integer nonlinear model for continuous steel casting production is proposed. For each casting line a set of allowed products is fixed; each product is characterized by a nominal length with a corresponding tolerance range. The model is used to formulate a constrained optimization problem whose objective consists of finding casting lines speeds and cutting plan that minimize scrap material...
In this paper we present the integration of a linear-time-varying model-predictive-control (LTV-MPC), designed to stabilize a vehicle during sudden lane change or excessive speed-entry in curve, with a slip controller that converts the desired longitudinal tire force variation in pressure variation in the brake system. The lateral controller is designed using a three-degrees-of-freedom vehicle model...
In this paper, we consider a class of cranes scheduling problem; cranes serve locations moving along a track and they can not over cross. By exploiting Petri nets formalism we obtain a model for crane movements and crane position constraints. We then consider task time-based constraints and formulate the general scheduling problem when the control target is to minimize a given objective function....
Unified Modeling Language is proposed as an effective framework for constructing simulation models of hybrid manufacturing systems. The plant processes jobs through a network of machines and buffers. Machines are represented as hybrid automata in which continuous time dependent operating conditions are modeled through ordinary differential equations. Machines are connected through buffers. Modularity,...
