An Introduction to Optimal Satellite Range Scheduling by Antonio Jose Vazquez Alvarez, Richard Scott Erwin

By Antonio Jose Vazquez Alvarez, Richard Scott Erwin

The satellite tv for pc variety scheduling (SRS) challenge, a massive operations learn challenge within the aerospace which includes allocating projects between satellites and Earth-bound items, is tested during this publication. SRS ideas and recommendations are acceptable to many components, including:

  • Satellite communications, the place initiatives are verbal exchange periods among units of satellites and floor stations
  • Earth remark, the place initiatives are observations of spots on this planet via satellites
  • Sensor scheduling, the place projects are observations of satellites through sensors at the Earth.

This self-contained monograph starts with a dependent compendium of the matter and strikes directly to clarify the optimum method of the answer, which include points from graph idea, set idea, online game idea and trust networks. This e-book is available to scholars, execs and researchers in numerous fields, together with: operations learn, optimization, scheduling thought, dynamic programming and online game conception. Taking account of the allotted, stochastic and dynamic versions of the matter, this booklet offers the optimum way to the fastened period SRS challenge and the way emigrate effects into extra advanced instances. Reference algorithms and conventional algorithms for fixing the scheduling difficulties are supplied and in comparison with examples and simulations in sensible scenarios.

S. Erwin, Robust fixed interval satellite range scheduling, in 2015 IEEE Aerospace Conference (IEEE, Big Sky, 2015). Chapter 2 Scheduling Process In this chapter we put the scheduling process in the context of the various missions that the problem arises in. This chapter is intended for readers that are approaching SRS, or for professionals from other industries, to show where all the constraints of this problem come from. As we mentioned in the previous chapter, SRS is applicable in satellite communications, Earth observation, and sensor scheduling.

2. We present in this chapter the baseline for the satellite range scheduling problem, and thus we start with the basic problem, where the topology is centralized so that the schedule can be computed once and for all the entities, which will follow it; and the interactions, characterized as requests, remain deterministic and unchanged along the scheduling horizon. 2 Model for the Requests The operators of the mission will define a set of requests for the interactions among the satellites and the ground stations, which will be constrained to occur inside the visibility windows described in the previous section.

Given that the problem from [14] can be solved in polynomial time for a fixed number of machines, the result is also extensible to the no-slack no-redundant no-precedence SRS problem with a fixed number of ground stations or satellites. From Definitions 2 and 8, SiRRSP is a subproblem of MuRRSP, and no-priority of priority. For the m-ary capacity case, we can transform those passes associated to multiple capacity entities into m passes associated to m fictitious entities in polynomial time, thus generating an instance of a problem with unitary capacity.
