Towards a Heuristic for Scheduling the James Webb Space Telescope
نویسندگان
چکیده
Scheduling the James Webb Space Telescope (JWST) requires modeling and minimizing the buildup of angular momentum of the spacecraft. Accounting for momentum management is expected to be a major driver of spacecraft efficiency and lifetime. We develop a heuristic that reduces momentum buildup and show how the heuristic can be used in a simulation of the operations concept for JWST scheduling. Through experimental data we show how the heuristic improves momentum usage while maintaining high spacecraft efficiency on a representative science mission for JWST. Finally, we explore how the momentum heuristic closely mirrors the strategies required to efficiently schedule the Hubble Space Telescope.

Multi-Objective Evolutionary Algorithms for Scheduling the James Webb Space Telescope
Effective scheduling of the James Webb Space Telescope (JWST) requires managing the trade-off between multiple scheduling criteria including minimizing unscheduled time, angular momentum build-up, and the number of observations that miss their last opportunity to schedule. Previous studies examined momentum management and wasted space and showed that effective JWST scheduling requires modeling ...
متن کاملAn Efficient Genetic Algorithm for Task Scheduling on Heterogeneous Computing Systems Based on TRIZ
An efficient assignment and scheduling of tasks is one of the key elements in effective utilization of heterogeneous multiprocessor systems. The task scheduling problem has been proven to be NP-hard is the reason why we used meta-heuristic methods for finding a suboptimal schedule. In this paper we proposed a new approach using TRIZ (specially 40 inventive principles). The basic idea of thi...
