The problem of choice the optimum law of nonuniform alloying the power core for preparation the anisotropic quartz fibres of Panda type

The problem of searching the optimum dependence of alloying by boron oxide the power core of anisotropic optical fiber of Panda type is considered. The task of optimization is set for the purpose of increase the common temperature deformation of a power core at performing the conditions of durability at all technological production phases. At the decision the method of Nelder-Meed is used. Restrictions under the terms of durability are considered by means of penal functions method. Parameters of optimization are coefficients of the function describing the distribution law on radius of a core of boron oxide in clear quartz. Dependence of distribution is approximated by two cubic splines. The optimum distribution law of alloying additives taking into account durability conditions is received.
