Abstract: For effectively managing and scheduling remotely sensed data processing task and improving the utilization ratio of processing resources, this paper presents a mathematical model of the problem based on the characteristics of the problem. A quick simulated annealing algorithm is proposed for solving this problem, which uses two types of neighborhood structure: total counterchange (including total redistribution and total swap) and local counterchange (including local redistribution and local swap). Finally, experiment results compared with the results of heuristic algorithm, show the effectiveness of the proposed approach.

Abstract: With the development of remote sensing technology, remote sensing data frequency-intensive has received and processed, the demand of remote sensing applications has kept an increasing growth. The management and planning for multi-source remote sensing data processing became very complicated with the evolution of remote sensed application requests. The way of effect management and scheduling can improve utility of processing resources and sufficiently exert abilities of remote sensing processing center. Based on the multi-objective optimization characteristic of the problem, this paper presents the mathematical model of the problem. An ant colony optimization algorithm is proposed for solving this problem. At last, experiments results show the effectiveness of our approach compared with the results of heuristic algorithm and simulated annealing algorithm.

Abstract: The slew operations of earth observation satellites are tightly constrained, observation scheduling with task merging can improve satellites observing efficiency. The model of satellite observation scheduling problem with task merging is proposed in this paper article and a Very Fast Simulated Annealing algorithm (VFSA) is developed to solve the problem. The VFSA algorithm employs compose and decompose neighborhoods for dynamic task merging. To avoid the local optimum solutions and improve the exploration abilities, re-annealing and three diversification strategies, perturb, rearrange and restart are defined in VFSA. Experiments results show the effectiveness of our approach.
