一、前言 网络计划技术是系统工程中的一个重要方法,由于它的先进性,科学性和有效性,近年来在国内外得到普遍的重视。它可以通过网络技术优化,正确地处理工期-成本关系,寻求生产网络在最低成本时的最佳工期,从而取得明显的经济效益。我国目前应积极创造条件使网络优化真正发挥作用。 I. Preface Network planning technology is an important method in system engineering. Due to its advanced nature, scientificity and effectiveness, network planning technology has gained universal attention at home and abroad in recent years. It can optimize the network technology, correctly handle the duration - cost relationship, the production network at the lowest cost to find the best time to achieve significant economic benefits. At present, China should actively create the conditions for network optimization to really make a difference.
