In this paper, we illustrate a new method to overcome the failures of the theory proposed by Elmaghraby and Kamburowski (1992) and De Reyck (1998) for the analysis of activity criticalities and flexibilities in non-preemptive project scheduling with generalized precedence relations under unlimited resources. These failures, discussed in detail in this paper, call for a new approach to study this problem. We provide new definitions of criticalities and consequently new tools for their identification within a more general framework without ambiguities.

具有广义优先关系的项目调度：一种分析关键性和灵活性的新方法

在本文中，我们说明了一种新方法来克服 Elmaghraby 和 Kamburowski（1992）以及 De Reyck（1998）提出的理论的失败，这些理论用于分析在无限条件下具有广义优先关系的非抢占式项目调度中的活动关键性和灵活性。资源。本文详细讨论了这些失败，需要一种新的方法来研究这个问题。我们提供了关键性的新定义，并因此在更通用的框架内提供了用于识别它们的新工具，没有歧义。
