DEVELOPMENT OF INTEGRATED CHEMICAL PROCESS DESIGN SYSTEM CONSIDERING LIFECYCLE

本研究的目的是开发一个考虑生命周期的化工过程集成设计系统。(1)利用IDEF0对过程生命周期进行分析，将过程生命周期分为分子设计、材料设计和工艺设计三个阶段，并将其表示为活度模型。该模型明确了活动之间的材料和信息流动。特别确定了设计间歇式工艺操作的配方制备要求。通过考虑产品生命周期信息和配方信息的收集方法，设计集成设计系统的结构。(2)提出了一种新的产品生命周期建模方法，包括原材料、生产、消费、回收和处置。通过对待设计工艺生产的产品的生命周期进行建模，我们可以评估产品对环境的影响，并可以在考虑生命周期的工艺设计活动中选择反应和溶剂。(3)设计了一个信息系统，将化工过程设计生命周期中的各个活动视为一个对象，实现化工过程设计活动之间的交互。然后，我们实现了原型软件，使我们能够在网络中利用分布式对象。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都需要进一步的研究。

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.
