The telescope scheduling is a key component of telescope operation, which is used to assist scientists to make reasonable observation plans, improve the operation efficiency of telescopes, and get high-quality data from observations. However, because of the different requirements of various science projects, the scheduling process of the telescope is very complicated. In this work, for the project of short-period and multi-objective observation, we consider the effects of slew time between two objectives and observation elevation of the telescope, and model the problem. The greedy algorithm is used to make a plan of pulsar TOA (Time of Arrival) observation of the Nanshan 26m telescope in Xinjiang Astronomical Observatory, Chinese Academy of Sciences. Simulations show that the list completed by the algorithm can reduce the slew time consumption of the observation process, improve the quality of observation data, and reduce the burden of scientists on the arrangement of the observation list.
