Computers & Chemical Engineering

Computers & Chemical Engineering (commonly abbreviated as Comput. Chem. Eng.) is a peer-reviewed journal published by Elsevier, founded in England in 1977 and issued twelve times a year. It is the longest established specialist title in process systems engineering, publishing original research that solves chemical engineering problems computationally.《计算机与化学工程》（Computers & Chemical Engineering，常用缩写为 Comput. Chem. Eng.）是由爱思唯尔出版的同行评审学术期刊，1977 年创刊于英国，现为每年十二期的月刊。该刊是过程系统工程方向历史最久的专业刊物，刊载以计算方法解决化工问题的原创研究。

Scope

Computers & Chemical Engineering holds that computational methods must land on engineering problems, asking for reproducible algorithms and worked examples of engineering consequence rather than comparisons of convergence speed on abstract instances. Its principal subject areas include:Computers & Chemical Engineering 的取稿立场是「计算方法必须落到工程问题上」，要求论文给出可复现的算法与具工程意义的算例，而非只在抽象算例上比较收敛速度。收文范围覆盖的主要方向包括：

• Process simulation: steady-state and dynamic flow-sheet simulation, equation-oriented and sequential modular approaches, and solution strategies with initialisation for large systems.过程模拟： 稳态与动态流程模拟、方程取向与序贯模块方法、大规模系统的求解策略与初始化。
• Optimisation and scheduling: mixed-integer nonlinear programming, global optimisation and convex relaxation, and modelling plus solution of production scheduling and supply chains.优化与调度： 混合整数非线性规划、全局优化与凸松弛、生产调度与供应链的建模求解。
• Process control and monitoring: model predictive and advanced control, data-driven fault diagnosis, and process monitoring with anomaly handling.过程控制与监测： 模型预测控制与先进控制、数据驱动的故障诊断、过程监测与异常处理。
• Machine learning applications: surrogate and reduced-order modelling, reinforcement learning attempted in process control, and model interpretability with data quality.机器学习应用： 代理模型与降阶建模、强化学习在过程控制中的尝试、模型可解释性与数据质量。
• Molecular and multiscale modelling: computer-aided molecular design, predictive modelling of thermodynamic properties, and bridging from molecule to plant.分子与多尺度建模： 计算机辅助分子设计、热力学性质的预测建模、从分子到工厂的跨尺度衔接。

Research articles and reviews predominate, joined by short communications and topical issues, and the journal asks that pseudocode or implementation detail be available, since conclusions without an account of method are not considered.稿件类型以研究论文与综述为主，兼收短篇通讯与专题专辑；本刊要求算法的伪代码或实现细节可查，仅有结论而无方法交代的稿件不予考虑。

History

• Founding (1977): the journal opened with volume 1 in 1977 under Pergamon Press, at the moment chemical engineering began bringing mainframe numerical power into flow-sheet calculation.创刊（1977年）： 本刊于 1977 年以第 1 卷创刊，由帕加蒙出版社出版，其时化工界正把大型机的数值能力引入流程计算。
• Discipline building: process systems engineering was not yet a settled discipline in the 1970s, and together with the conference series founded at about the same time this journal gave the subject a fixed place to publish and to argue.学科建制： 过程系统工程在二十世纪七十年代尚未成为稳定学科，本刊与同期成立的系列会议一道，为该方向提供了固定的发表与交锋场所。
• Publisher transition: Pergamon Press was later absorbed into Elsevier and the title moved with it, while the place of publication has continued to be recorded as England.出版方更替： 创刊时的帕加蒙出版社其后并入爱思唯尔集团，本刊随之转入后者名下出版，注册地仍记为英国。
• Frequency: issues appeared quarterly at first, moving to monthly around the 1990s and settling at twelve a year, where it remains.刊期演变： 本刊创刊初期为季刊，二十世纪九十年代前后转为月刊，其后固定为每年十二期并沿用至今。
• Metric trend: the impact factor climbed from 3.1 in 2017 to 4.1 in 2021 and stood at 4.9 in 2025, upper-middle in both chemical engineering and interdisciplinary computer applications.指标走势： 影响因子自 2017 年的 3.1 缓步上升至 2021 年的 4.1，2025 年为 4.9，在化工与计算机跨学科应用两类目中均列中游偏上。

Editors

An editor-in-chief directs the journal with an international board, and referees come mainly from process systems engineering and computational mathematics. Manuscripts arrive online, and expectations on instance size and reproducibility are raised at triage. Neither the publisher nor the board publishes an acceptance rate or review duration for the title.本刊由主编统筹并设国际编委会，评审人以过程系统工程与计算数学两方面专家为主；稿件经在线系统投递，编辑部对算例规模与可复现性的要求在初审即提出。出版方与编委会均未公布本刊的录用比例与审稿时长。

• Reproducibility: authors must give complete data or a generation procedure for their instances, and work reporting results without reproducible inputs is often asked to supply them.可复现性： 编辑部要求作者给出算例的完整数据或生成方式，仅给结果而无可复现输入的工作常被要求补作。
• Engineering relevance: the office judges whether instances are of engineering scale, and algorithms validated only on toy problems without scaling tests struggle in review.工程意义： 编辑部会判断算例是否具备工程规模，仅在玩具问题上验证算法而不作工程缩放的稿件难以通过评审。
• Conference links: subject matter overlaps heavily with the international conferences of process systems engineering, extended conference papers are often gathered here, and post-conference expansion is encouraged.与学会的关系： 本刊的题材与过程系统工程领域的国际会议高度重叠，会议扩展论文常在此结集，编辑部亦鼓励事后扩展投稿。
