The benefits due to the utilization of chemicals are the important foundation of industries and consumers. In the contrast to the positive aspects of chemical substances, some chemicals have been marked, concerned carefully, and finally, regulated, because of the previous accidents, damages, and impacts on the environment, health, and safety (EHS). The design and operation of process system should be able to address such risk originating from decision. Various methods and technologies have been developed for supervising the positive and negative aspects of chemical substances. The implementation of such knowledge on process systems engineering into practice has been necessitated.//This thesis presents the structuration of knowledge on process design and evaluation for risk-based decision making, where different assessment methodologies such as LCA and RA are appropriately applied on their perspectives and logically connected with business activities in practicable style. The risk-based decision making should be considered not only at the early design phase of process and project, but also at the process improvement phase. For activating such continuous improvements, the practicability of risk-based approaches is enhanced. The actual case study of implementing risk-based decision making was performed on the design of metal cleaning.//Knowledge structuration was defined in this thesis as five acquisition and conversion concepts of knowledge: experience and experiment, reasoning analysis, association, extended association, integration with activity, and activation by mechanism. The related knowledge on process design and evaluation was divided into five categories of knowledge: the methods of risk specification (RSM), evaluation (EvM), alternative generation (AGM), process simulation (PSM), and risk interpretation (RIM).//A method of associating LCA and RA into decision making was developed for EvM. The meanings of indicators in LCA and RA were carefully analyzed. The main difference of them is the temporal and spatial aspects of evaluated risks. Based on the objectives of assessment and decision making, the knowledge on process evaluation should be connected with design activities. For appropriate and effective utilization of different assessment methodologies, RSM for selecting risk indices and indicators was proposed on the basis of scientifically- and practically-validated logic. Additionally, the attributions of risk indices and indicators were specified as the temporal and spatial aspects, to associate the knowledge on assessment. These enable the comprehensive consideration of risk occurred by decision.//For AGM based on the evaluation results of process in use, the requirements of process models were defined, and they were developed through reasoning and associating the evidences from experiments by actual industrial machine and CFD analysis. Obtained knowledge on process behavior was stored as decision tables for alternative generation. Based on the needs from EvM and AGM, quantitative process models for PSM were developed by physical analysis. Such models enable the evaluation of alternative processes. The way of interpreting all evaluation results can be based on RIM enabling absolutely understanding of the physical meanings of risk indices and indicators and relatively comparison of the evaluation results. Both are available in risk-based decision making, and knowledge utilized in risk specification can be useful resources.//The interaction of each method was analyzed and implemented into a business model visualized by IDEF0 function modeling language. At the same time, the information system models required for the activation of risk-based decision making can be discussed and modeled by IDEF1x and UML information modeling languages. The combination of these modeling languages can visualize the achievements of knowledge structuration.//The general applicability of knowledge structuration and proposed structured knowledge on process design and evaluation was verified by discussion on the inclusion of them into the existing concept for process improvement. The effective and appropriate implementation of such scientific knowledge into practice needs several models on activity and information. For making it more effective, the templates for strategic problem identification, knowledge structuring, business activity, and software information modeling were developed.//In summary, this thesis proposes the templates of promoting knowledge structuration as well as appropriate structured knowledge on process design and evaluation. The pentagonal knowledge structure and its business activity and supporting software system models are the scenario-based framework of applying engineering and scientific knowledge into practice in risk-based decision making. It can be a strong milestone for the knowledge structuration implementing distributed knowledge, skill, technology, and heuristics into practice for improving decision making for sustainable future.","subitem_description_type":"Abstract"}]},"item_7_dissertation_number_26":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第24630号"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6465","nameIdentifierScheme":"WEKO"}],"names":[{"name":"菊池, 康紀"}]}]},"item_7_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00002280","subitem_identifier_reg_type":"JaLC"}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"doctoral"}]},"item_7_text_22":{"attribute_name":"学位分野","attribute_value_mlt":[{"subitem_text_value":"Engineering (工学)"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"Department of Chemical System Engineering, Graduate School of Engineering (工学系研究科化学システム工学専攻)"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"博工第7064号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院工学系研究科 化学システム工学専攻"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kikuchi, Yasunori"}],"nameIdentifiers":[{"nameIdentifier":"6464","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-31"}],"displaytype":"detail","filename":"1237956302._5758.pdf","filesize":[{"value":"5.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1237956302._5758.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/2286/files/1237956302._5758.pdf"},"version_id":"cb21fc5d-93c4-45b4-a178-77a76f955d1a"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Structuration of Knowledge on Process Design and Evaluation for Risk-Based Decision Making","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Structuration of Knowledge on Process Design and Evaluation for Risk-Based Decision Making"}]},"item_type_id":"7","owner":"1","path":["280","317"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-03-01"},"publish_date":"2012-03-01","publish_status":"0","recid":"2286","relation_version_is_last":true,"title":["Structuration of Knowledge on Process Design and Evaluation for Risk-Based Decision Making"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:43:55.135288+00:00"}
