Optimization Models for Batch Scheduling

Having presented the general features of typical batch scheduling problems we introduce a roadmap that describes the main features of current optimization 

In order to overcome the previous limitations and generate data-independent models, a wide variety of optimization approaches employ a continuous-time representation. In these formulations, timing decisions are explicitly represented as a set of continuous variables defining the exact times at which the events take place.

In contrast to the discrete-time representation, continuous-time formulations are based on an extensive range of alternative event representations which are focused
