摘要

由于化学工艺的复杂性及其目标函数的多样性,改进工艺设计需要广泛的知识、大量的时间和巨大的人力资源。然而,基于机器学习的方法使用大量积累的数据,通用性有限,仅适用于特定工艺,无法理解模型决策的基础。本研究提出了基于 GPT 的改进工艺混合变换器(GIPHT),这是一种利用大型语言模型(LLM)的工艺设计改进生成系统。LLM 基于自然语言,无需可解释的人工智能分析就能理解模型决策的基础。GIPHT 由多智能体组成,可为不同的化学工艺提供更多的功能和性能。我们还提出了 "详细简化流程图输入行输入系统 "格式,以自然语言表达流程图,包括有关流程条件的增强信息。我们采用了结构化提示系统,并通过提示工程在 LLM 领域进行了验证。GIPHT 根据其提出的改进方法搜索和提取数据,为决策过程和依据提供解释,克服了传统黑箱人工智能模型的局限性。它为处于工艺设计早期阶段的设计工程师提供了方向性思路,并可用于培训工艺工程师,支持改进过时的工艺并将其转化为更环保的工艺。

GPT Prompt Engineering for a Large Language Model-Based Process Improvement Generation System

Process design improvements require extensive knowledge, considerable time, and huge human resources due to the complexity of chemical processes and their diverse objective functions. However, machine learning-based approaches using vast accumulated data are limited in low versatility, applicable only to specific processes, and unable to understand the basis of model decisions. This study proposes the GPT-based Improved Process Hybrid Transformer (GIPHT), a process design improvement generation system utilizing Large Language Model (LLM). LLMs, being natural language-based, allow for understanding the basis of model decisions without need of explainable AI analysis. GIPHT is composed of multi-agent to enhance versatility and performance for diverse chemical processes. We also propose the Detailed Simplified Flowsheet Input Line Entry System format to express process diagrams in natural language, including enhanced information about process conditions. A structured prompt system is employed and validated in the LLM domain through prompt engineering. GIPHT searches and extracts data based on its proposed improvement methodology, providing explanations for the decision-making process and the basis, overcoming limitations of the traditional black-box AI models. It offers directional ideas to design engineers in the early stages of process design and would be used for training of process engineers, supporting improvement of outdated processes and transformation into more environmentally friendly processes.

期刊介绍: The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
