【摘要】：具有时间转化约束项目网络是对传统网络的创新,其考虑了时间转换约束对项目网络的影响。但是,在已有时间转换约束项目网络的研究过程中都是假设在整个工期内工作效率是固定不变的,忽略了人为因素。而人在工作过程中具有学习效应,即随着时间的推移人由对活动的生疏逐渐到能够熟练完成活动,在这个过程中工作效率也有了很大的提高。本文在前人研究的基础上,考虑了人的行为因素对具有时间转换约束网络的影响,给出了在人的学习效应和时间转换约束双重作用下的机动时间的计算公式,进而给出工序持续时间的计算公式,并在此基础上建立了网络关键线路的变化模型。最后,通过实例验证了该模型的有效性和合理性。
[Abstract]:The project network with time conversion constraints is an innovation to the traditional network, which takes into account the influence of time conversion constraints on the project network. However, in the research of the existing project network with time conversion constraints, it is assumed that the work efficiency is fixed and the artificial factors are ignored. In the process of work, people have the effect of learning, that is, with the passage of time, people gradually from the unfamiliar activities to be able to skillfully complete the activities, in the process of work efficiency has also been greatly improved. On the basis of previous studies, this paper considers the influence of human behavior factors on the network with time conversion constraints, and gives a formula for calculating maneuvering time under the dual action of human learning effect and time conversion constraint. Then the calculation formula of the working procedure duration is given, and the variation model of the network critical circuit is established on the basis of the formula. Finally, the validity and rationality of the model are verified by an example.
