Incorporating dynamic information of upstream activities by downstream activities
Yanyan Liu · Computer Integrated Manufacturing Systems · 2011
An experience condition for information released by upstream activities was presented based on knowledge accumulation rate and relevance between upstream information and downstream activities.Aiming at the time of downstream activities incorporating dynamic information of upstream activities,a model of net benefit was constructed considering trade-off between benefits and the rework cost of incorporation on the premise of a fixed deadline,non-linear evolution of performance and uninterruppted time.Net benefit maximization was proved to be existed.A threshold for downstream activities incorporating dynamic information of upstream activities was presented.That was to say,incorporation only occurred when the information arriving time was greater than or equal to this threshold,otherwise ignored this piece of information to wait for more information.A numerical example was given to verify the rationality of the model.
