In the sense of Von Karman large displacement, the governing equation of nonlinear dynamic response of the clamped circular plates under impact of a mass is established by using the virtual displacement principle and Galerkin's method in this paper. The effect of coupling between the impact load and the displacement of. the circular plates is considered. The governing equation is solved by applying the time increment method and the singular perturbation theory, and the asymptotic solutions of nonlinear dyna...

ABSTRACT According to the point of view of enterprise strategy management, Activity-Based Management of Whole Business Process combines supply, production and distribution of enterprise tightly and appropriately. In strategic, from the high point when all comes to all of enterprise, ABMWBP attaches importance to effect of every activity to targets of management and strategy, and advocates that every activity must be for whole benefits. In tactics, by going into the most elementary part of enterprise business---activities, and by controlling resources consumed by it, costs of activities are reduced and the process efficiency is improved greatly.

企业生产经营全过程作业管理的理论和方法是从企业全过程的战略高度出发，把企业供、产、销有机地结合在一起；在战略上，全过程作业管理站在企业全局的高度，重视每一项作业对企业经营目标和战略目标的作用，提倡每一项作业的安排必须服从企业的整体利益；在战术上，它通过深入到企业生产经营最细微的作业层次，从构成企业基本活动的作业着手，通过控制作业的资源消耗，达到控制企业成本、提高过程效率的目的。
