Types of Scheduling in Flexible manufacturing systems
This is known that a flexible manufacturing system consists of many components that are employed for control, monitoring and processing of the overall system. For the clear demonstration a typical layout of flexible manufacturing system is shown in following figure. For the overall system coordination, the coordination of all components is significant. The typical components in flexible manufacturing system that are normally scheduled are:
(a) AGV scheduling,
(b) Pallet scheduling, and
(c) Machine Scheduling.
A description of sample dataset is shown in Table no.3.
