本文根据与L~1优化设计问题等价的线性规划问题具有的对称结构,给出了一种确定初始基本容许解的方法。对于单变量系统和线性加权法多变量系统L~1优化设计问题,不须引入人工变量,对多变量系统L~1优化的min-max解法只需引入部份人工变量,並且引入的方法也具有特色。 According to the symmetrical structure of the linear programming problem which is equivalent to the L ~ 1 optimal design problem, this paper gives a method to determine the initial basic allowable solution. For the optimal design of L ~ 1 in multivariable systems with single variable system and linear weighted method, no artificial variables need to be introduced, only some artificial variables need to be introduced for the min-max solution of multivariable system L ~ 1 optimization, and the methods introduced Distinctive.
