Abstract
This paper analyzes Telemetry, Track and Command(TT&C) requirement of TT&C schedule problem and constructs a 0-1 integer programming model for TT&C schedule problem. The model's constraints are relaxed respectively by three kinds of relaxation strategies( (λ,v), and (μ, v) and (λ,μ) ), and three kinds of Lagrangian relaxation problems are obtained, and each relaxation problem's upper bound is obtained by subgradient optimization algorithm. It demonstrates validity of upper bound obtained by subgradient optimization algorithm by two scenarios, and the influences of different relaxation strategies on performance of algorithm are compared.关键词
