This work proposes a decision-making framework that integrates models, data, and decision-makers into data-connected decision cells, organized within a decision graph. The framework formalizes decision processes and enables systematic and adaptive workflows across decision layers. The framework can be applied to various use cases, including supply chain optimization and process design, to address the evolving challenges of the chemical industry. It enables a shift from component-level optimizations toward system-wide optimization strategies that account for the interconnected nature of complex production systems.</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"97 4","pages":"344-354"},"PeriodicalIF":1.5,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.202400118","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the filtration kinetics of a depth filter can be investigated using various model approaches (dendrite growth model or fiber growth model) to describe particle separation in the clogging phase, it is not yet possible to transition to surface filtration by continuing the same model calculation. A new modeling approach with a multilayer construction and an offset for the growth of the dust cake is presented, which enables the description of particle separation by using analytical models throughout the entire filtration process without a separate add-on model for the change between depth and surface filtration. The continuous evaluation of the locally resolved structural changes, i.e., in the individual sub-layers, as well as the associated changes in the separation efficiency of the single-collectors in the growing two-component filtering system provide insightful information about the filtration kinetics during the entire filtration process and about the process of dust cake formation.<sup>1)</sup></p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"97 4","pages":"334-343"},"PeriodicalIF":1.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.202400154","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
