“…The satellite image downlink scheduling problem and its variations have been studied by many authors. Some of these works were focused on case studies for specific satellites or space missions [11,14,20] whereas others are more general purpose in nature [9,10,12,15,16,29,31,32,33]. Literature from machine scheduling [7,25,28,27] and resource-constrained project scheduling [19,26] are also relevant in solving the satellite image downlink scheduling problem (SIDSP).…”
