Considering the gap between academic research and real world application, the characteristic of manufactories of "much variety and little batch", this paper discusses the abstraction and modeling of the workshop performance using colored Petri net characterizing definite description of DEDS. And rule bases are applied into the model to tackle the dynamic events and disturbances with dynamic scheduling. After analysis on agile response of MES and integration of its scheduling model, by adopting distributed component technology the workshop scheduling model was capsulated as a scheduler to realize the scheduling module of MES easier to be integrated and rapidly reused. Finally a prototype of scheduler is proposed.

鉴于最优调度理论与实际调度应用的距离，以及多品种单件小批量车间生产的特点，本文以某模具制造企业生产车间为研究对象，利用对离散动态系统具有准确描述能力的着色 Petri 网对车间生产进行了抽象和建模；并通过向网系统中引入规则约束，为车间内的动态事件和扰动提供了动态调度；在对 MES的敏捷性及其车间调度模块的集成性进行了多方面分析后，利用分布式组件技术将调度模型进行了软件封装，以便为 MES 提供一个功能独立、易集成、可快速重用的生产调度模块；最后给出了一个 MES 车间调度服务器和调度室客户程序的原型实现。

Based on the acquisition –processing-abstraction of data, the structures an quantities of land use/cover change, the change of degree, the land use/cover dynamic degree and the index of the land use/cover dynamic degree were researched and analyzed comprehensibly in two different periodes(1990-1999,1999-2002) and sum up the conclusion.

结构变化不明显。水域、居民地、耕地动态度比较大，变化较为剧烈；未利用地动态度最小，变化缓慢。1990-2002年间水域、居民地、耕地与其他土地利用/覆盖类型间相互转化面积差额较大，转入面积大于转出面积，即在相互频繁转换同时单边转入明显；林地、草地、未利用地与其他土地利用/覆盖类型间相互转化面积差额不大，处于一种动态均衡状态。

By referring to these cases and models, essential abstraction was drawn to facilitate theoretical analysis, which makes this paper more convincible.

objective:with the local lobster shell as the raw material,we inquire into the abstraction and preparation of chitin and chitosan to develop a new raw material resources for chitosan.methods:use methods such as take off protein,calcium,colour,deacetylate and purification to prepare chitosan to study deacetylate degree,molecular weight and other characters of chitosan,then compare with infrared spectrum of bio-chemical chitosan on market.results:the chitin and chitosan obtained from lobster shell are 14.8% and 8.9%, respectively.
