Process Accompanying Simulation – a General Approach for the Continuous Optimization of Manufacturing Schedules in Electronics Production

چکیده
The paper will present the successful realization of simulation based manufacturing planning and control in electronics production. The principle has been implemented in various applications as supplementary decision aid in connection with ERP systems. A theoretical model of virtual and real time explains relations between simulation and production planning. In all cases the discrete event simulator ROSI has been used, which provides comfortable functions for manufacturing models. Scenarios are being optimized by meta-heuristic methods like Genetic Algorithms. As real production and simulation are producing data in the same logical format, a comparison technique is being proposed that enables the observation of errors between reality and simulation, where simulation can be retriggered when the error is rising too high. In addition the adaptation of parameters is derived of this comparison. Examples clarify all contributions.

Periodic flexible maintenance planning in a single-machine production environment
Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...
