Simulation as one of the core technologies for digital enterprises: assessment of hybrid scheduling methods

The paper tackles the problem of managing the uncertainties during the execu-tion of predictive schedules in a dynamic environment. The dynamic environ-ment in question is represented by a simulation model – connected to a produc-tion scheduler system – with flexible modelling capabilities. The paper ad-dresses the simulation module of the proposed architecture highlighting its main functionalities and advantages, compared to former simulation-based so-lutions. By applying the proposed architecture, which constitutes a coherent part of a Digital Factory solution, the solution methods for stability-oriented rescheduling can be profoundly tested and analyzed. Evaluation of several scenarios of the rescheduling threshold and the timing of rescheduling are also presented in a case study
