Abstract
This research presents AGVS implementation
procedures for JIT systems. The introduced AGVS is
dispatched by input and output thresholds imposed on
the input and output queues of work stations.
Threshold values are computed based on process time.
The physical states of queues are detected by sensing
devices and compared with thresholds to dispatch
vehicles. Methematical model is defined to calculate
required number of vehicles. Three guided-path
models of AGVS are introduced: chessboard
unidirectional, tandem bi-directional, and cyclic bidirectional
guided-path models. Simulation models are
established to perform system simulation for
performance evaluation. Vehicle number is updated
by analyzing the simulation results. Moreover, based
on the performance evaluation, the best guided-path
model should be adopted for actual system
implementation.
