An algorithm to modify consistent initialization of differential-algebraic equations obtained by pantelides algorithm using minimally singular subsets

In this paper, an algorithm for index reduction of differential algebraic equations (DAE) is proposed. Pantelides has already been proposed as purpose. This conventional succeeded in reducing the calculation time required reduction. However, there exist some DAE systems whose cannot be reduced correctly with because it uses sufficient condition to reduce index. We propose modify solution obtained by deal a wider class systems. The deals using necessary and systematically that algorithm. implemented functions on Maxima evaluated examples.
