一个用于工程系统最优设计的混合整数非线性规划方法的改进

A Modification to ″Mixed Integer Non-Linear Programming and Optimal Design of Chemical Engineering System″

对文献［２］中所提出的一个用于化学工程系统最优设计的混合整数非线性规划方法及其算法进行分析。举例说明原算法所存在的不足，指出在某些情况下该算法难于执行的原因。在原算法的构思下改进了算法，并给出了收敛性证明，保证了改进算法的可执行性，使算法具有更好的适用性和有效性。

In this paper some oversights and omissions are discussed about a MINLP Algorithm for Engineering System Design(see Journal of Chemical industry and Engineering (China), 1991, 42(l). P33～39). The mistakes and causes are illustrated with a numerical example. In order to ensure the feasibility of the algorithm for implementation, thepaper proposes a modification to the original algorithm and proves its convergence.
