Event Driven Dynamic Scheduling System in Electronic boards Assembly

This paper introduces a dynamic scheduling/rescheduling system for the definition of an operating production plan, regarding the automatic insertion of electronic components on printed circuit boards. Thanks to the characteristics of the dynamic scheduling system, the plan is updated during the planning period as a reaction to any event which causes disturbances on the production process flow. Objective of the reactive scheduler is to manage ''disturbances'', which could be either technical (e.g. machine downtime) or logistic (e.g. urgent orders; lack of components), while pursuing several objectives such as the minimisation of setup number as well as setup times, and the minimisation of the production makespan
