DEVELOPMENT OF INTEGRATED CHEMICAL PROCESS DESIGN SYSTEM CONSIDERING LIFECYCLE

(1)利用IDEF0对由分子设计、材料设计和工艺设计组成的过程生命周期进行了分析，并将其表示为活动模型。该模型明确了活动之间的物流和信息流。特别是确定了设计间歇过程操作所需的配方制备要求。通过考虑收集产品全生命周期信息和配方信息的方法，可以设计出集成设计系统的结构。(2)提出了一种由原材料、生产、消耗、回收和处置组成的产品全生命周期建模方法。通过对待设计过程所产生的产品的生命周期进行建模，可以对产品的环境影响进行评价，并可以在考虑生命周期的过程设计活动中选择反应和溶剂。(3)以生命周期中的每一项活动为对象，设计了一个与化工过程设计活动交互的信息系统。在此基础上，实现了原型软件，使我们能够利用网络中的分布式对象，在对象间接口的标准化、详细模型的开发、与其他仿真环境的连接以及优化模块的加入等方面还需要进一步的研究。

The am of this study is to develop an integrated chemical process design system considering lifecycle.(1) Process lifecycle, which consists of molecular design, material design and process design, was analyzed and represented as an activity model using IDEF0. This model clarified the flow of materials and information between activities. Especially, requirements for the preparation of recipes to design batch process operation were determined. The structure of integrated design system can be designed by considering method to gather the information of product lifecycle and the recipes.(2) A new method to model product lifecycle, which consists of raw materials, production, consumption, recycling and dispose, was developed. By modeling the lifecycle of product produced by the process, which is to be designed, we can evaluate the environmental impacts of the product and can select reactions and solvents in the process design activity considering lifecycle.(3) An information system was designed to interact the chemical process design activities by treating each activity in the lifecycle as an object. Then, we implemented prototype software, which enables us to utilize distributed objects in network.Standardization of interface between objects, development of detailed model, connection of other simulation environment and inclusion of optimization module is needed in further study.
