Projects on steel‐making plant follow the stages of steel‐making plant system life cycle. In each life cycle stage, there are exit criteria to be fulfilled before a project can continue to the next stage. Among the exit criteria, we focus on one of the technical exit criteria, that is, the technology maturity. Technology maturity is measured using technical readiness level (TRL) and TRL concept has been largely adopted by numerous organizations and industry. However, the assignment of a certain TRL as one of the exit criteria of life cycle stages are not well adapted. In other words, TRL is not considered as a critical exit criteria of a system life cycle stages. In this paper, we would like to propose that the TRL should be one of the exit criteria of each life cycle stage. In this research, we propose a steel‐making plant system life cycle, define the technical readiness level for a steel‐making plant, and assign a target TRL for each life cycle stage as an exit criteria of that stage. The benefits of target TRL assignment to the life cycle stages are as follows: (1) the technical risk of developing/inserting a technology can be controlled on each life cycle stage, (2) the cost incurred if the technology to be developed/inserted is failed can be analyzed in each life cycle stage, and (3) as a standardization effort of technology readiness at each industrial plant life cycle stage. By directly assigning target TRL for each life cycle stages, we look forward to a more coordinated (in terms of exit criteria) and highly effective (in terms of technical risks identification and eventually project failure prevention) technology development and assessment processes.
Engineering industry is considered as a key industry which will drive the future of Korea. However, Korean engineering companies have recently made a huge loss and the lack of engineering capability is pointed out as a main cause of this situation. Unlike Korean engineering companies, world leading engineering companies have their own systems Engineering Standards/Guides ensuring successful fulfillments of the feasibility study, concept design and basic design processes.
An Engineering standard for an organization is an essential means to shorten the time for engineering design, to maintain the engineering quality and to secure the engineering efficiency in the development of the complex system. One of the main reasons of Korean Engineering companies' lack of engineering capability is the absence of the Engineering standard.
In the paper, we have developed a steel‐making plant Engineering standard based on a systems engineering standard. We used both ISO/IEC/IEEE 15288 and NASA SE Handbook as main reference standards. First, we have introduced a lifecycle definition and a product breakdown structure of a general steel‐making plant. Then we have introduced detailed engineering processes of feasibility study and concept design phase. Finally we have introduced exit criteria for outputs of feasibility study and concept design phase to assess the degree of achievement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
