Notes: -the number of new tasks, disturbance-the number of common tasks that are rearranged in the adjusted schedule, NC: the number of emergency tasks completed, NITM: the number of emergency tasks inserted by task merging, NI: the number of emergency tasks inserted directly, NIR: the number of emergency tasks inserted by rearranging, and NID: the number of emergency tasks inserted by deleting.
