  A new field re-configuration technique, Multiple Rooks of Chess (MRC), for
multiple deployable Integral Field Spectrographs has been developed. The method
involves mechanical geometry as well as an optimized deployment algorithm. The
geometry is found to be simple for mechanical implementation. The algorithm
initially assigns the IFUs to the target objects and then devises the movement
sequence based on the current and the desired IFU positions. The
reconfiguration time using the suitable actuators which runs at 20 cm/s is
found to be a maximum of 25 seconds for the circular DOTIFS focal plane (180 mm
diameter). The Geometry Algorithm Combination (GAC) has been tested on several
million mock target configurations with object-to-IFU ({\tau} ) ratio varying
from 0.25 to 16. The MRC method is found to-be efficient in target acquisition
in terms of field revisit and deployment time without any collision or
entanglement of the fiber bundles. The efficiency of the technique does not get
affected by the increase in number density of target objects. The technique is
compared with other available methods based on sky coverage, flexibility and
overhead time. The proposed geometry and algorithm combination is found to have
an advantage in all of the aspects.
