  Aiming at improving the survey efficiency of the Wide Field Survey Telescope,
we have developed a basic scheduling strategy that takes into account the
telescope characteristics, observing conditions, and weather conditions at the
Lenghu site. The sky area is divided into rectangular regions, referred to as
`tiles', with a size of 2.577 deg * 2.634 deg slightly smaller than the focal
area of the mosaic CCDs. These tiles are continuously filled in annulars
parallel to the equator. The brightness of the sky background, which varies
with the moon phase and distance from the moon, plays a significant role in
determining the accessible survey fields. Approximately 50 connected tiles are
grouped into one block for observation. To optimize the survey schedule, we
perform simulations by taking into account the length of exposures, data
readout, telescope slewing, and all relevant observing conditions. We utilize
the Greedy Algorithm for scheduling optimization. Additionally, we propose a
dedicated dithering pattern to cover the gaps between CCDs and the four corners
of the mosaic CCD array, which are located outside of the 3 deg field of view.
This dithering pattern helps to achieve relatively uniform exposure maps for
the final survey outputs.
