English Abstract
Flexible Manufacturing Systems are computer controlled systems consisting of programmable numerically controlled machines, tools, load/unload stations, automated material handling system, and a real-time control system.
It is required to design and implement real-time scheduling algorithms to generate a sequence of operations and task flows in order to use available resources.
Therefore, it is necessary to assign a priority for each operation and each task in order to balance the workload of available machines and tools.
This can be achieved by using real-time fuzzy-based scheduling algorithms to minimize the time required to complete each task.
Several parameters related to the required operations have been considered in sequencing and routing.
In this research, an FMS with four CNC machines (two drilling machines, and two milling machines) combined with a load/unload station and a conveyor belt are proposed.
The labVIEW environment has been used for the system realization and testing.
A fuzzy logic algorithm was used in scheduling modules to reduce system complexity when dealing with incomplete data and vague information.
Three fuzzy-based algorithms were applied; the first one for operation sequencing, the second one for task sequencing, while the third one is used for task routing.
Computer simulations for several case studies have been done to test and proof the flexibility of the system and the effectiveness of the proposed schedulers.
The obtained results concluded that the proposed methodology for sequencing and routing is promising for such FMS.
The performances of the proposed fuzzy scheduling algorithms are compared with those obtained from published literature.
The obtained results show clear improvement has been achieved by applying fuzzy algorithms in sequencing and routing.
