项目摘要

A pipe-less batch plant has attracted special interest recently for multipurpose manufacturing of high-functional chemical products. The recipe-driven autonomous distributed operation and management system for the advanced plant was investigated by referring to some techniques of the distributed artificial intelligence.1. The process sequence with various characteristics of chemical plants is written in a form of the recipe that consists of several sub-parts. Each sub-recipe is allocated to a proper hardware unit during execution of a process. The whole plant is appropriately operated only with local communication among the concerned units.2. The instantiation of recipe makes possible the generality of recipe and the appropriate placing of knowledge and decision making. Consequently, the operation and management system is realized not only with the advantage caused by the distribution, i. e., the even load and the easiness of maintenance, but also with the consistency that is indispensable for the chemical plants.3. A message protocol based on the contract net model is successfully applied for negotiation among multiple units. By using the action of reserve in allocating units, local schedule is appropriately performed.4. A dynamic and hierarchy approach to the complicated multiple criteria decision-making is proposed by referring to the analytic hierarchy process (AHP).

无管间歇装置最近引起了人们对多功能高功能化工产品生产的特别兴趣。借鉴分布式人工智能的一些技术，研究了基于配方驱动的先进工厂自主分布式运行管理系统。具有化工厂各种特点的工艺序列是以配方的形式编写的，该配方由几个子部分组成。在过程执行期间，每个子配方被分配给适当的硬件单元。只有在有关机组之间进行本地通信的情况下，整个工厂才能正常运行。配方的实例化使配方的通用性成为可能，使知识和决策的合理放置成为可能。从而实现了运行管理系统，既具有分布式带来的负载均匀、维护方便的优点，又具有化工厂不可缺少的一致性。一种基于合同网模型的消息协议被成功地应用于多个单元之间的协商。利用储备在分配单位中的作用，适当地执行当地的计划。针对复杂的多目标决策问题，借鉴层次分析法，提出了一种动态递阶决策方法。
