This paper is based on the interim result of ongoing research and development project to develop a software system which support procurement activities, namely PeMSS (Procurement Engineering Management Support System). PeMSS is a system that enables development requirements for each equipment and help designing equipment meeting the purchase requirements. Procurement at EPC (Engineering Procurement and Construction) and operational stage of a plant is an important area that determines the integrity and profitability of the plant. Procurement of unsuitable equipment due to selection of suppliers that do not meet or omit critical requirements in purchase specification can result in enormous cost increase due to such as delay in EPC project, unsatisfactory performance and reduced plant operation time. In spite of the importance of the procurement engineering, there is a lack of support system for systematic preparation of purchase specification, so development of the procurement specification is basically relying on the experience of the engineers in charge. Accordingly, it is needed to develop the PeMSS to help procurement engineers develop procurement specification based on systems engineering approach. This paper introduces the design of the PeMSS.

Supercritical carbon dioxide power system is the next generation electricity technology expected to be highly developed. The power system can improve net efficiency, simplify cycle configuration, and downsize equipment compared to conventional steam power system. In order to dominate the new market in advance, it is required to found Front End Engineering Design (FEED) Framework of the system. Therefore, this study developed the FEED framework including design processes for the supercritical carbon dioxide power system, information elements for each process, and relationships for each element. The developed FEED framework is expected to be able to secure systematic technological capabilities by establishing a common understanding and perspective among multi-field engineers participating in the design.

After the era of big data has arrived, the big data technology has been applied to diverse industries including communication, distribution, banking, and so on. With the increasing importanace of the big data in conventional industries, it has also been applied to plant industry recently. This paper reviews the current status of the big data in plant industry, including its concept, cases, applied technologies, analytic methods, and effects. To do this, this paper reviews the existing literatures from oil and gas plant, nuclear power plant. This research is expected to contribute to identify the opportunities of the big data in plant industry.

Steel in a continuous reheat furnace is heated to higher temperature to be treated in the rolling steel process. Due to this reason the continuous reheat furnace system requires an optimal control system to adjust the temperature inside the furnace. Level 2 control systems for continuous reheat furnaces generate automatic heating set points for the level 1 system of the furnace based on the mathematical thermal model which can give a good estimation of steel heating inside the furnace and is used to adjust heating requirements to optimize furnace combustion. For the current study the analytic methodology based on the design procedure from the systems engineering to develop new level 2 control system of a continuous reheat furnace was proposed. The system analysis and the requirements of the level 2 control system were derived using the unified modeling language (UML) 2.0, and the design of database and the graphic user interface (GUI) for the level 2 control system were conducted.

Implementation of Model-based Systems Engineering(MBSE) depends on a model supporting efficient communication among engineers from various domains. And SysML is designed to create models supporting MBSE but unfortunately, SysML itself is not practical enough to be used in real-world engineering projects. SysML is designed to express generic systems and requires specialized knowledge, so a model written in SysML is less capable of supporting communication between a systems engineer and a sub-system engineer. Domain Specific Languages(DSL) can be a great solution to overcome the weakness of the standard SysML. A SysML based DSL means a customized SysML for a specific engineering domain. Unfortunately, current researches on SysML Domain Specific Language(DSL) for the plant engineering industry are still on the early stage. So as the first step, we have developed our own SysML based Piping & Instrumentation Diagram (P&ID) creation environment and P&ID itself of a specific plant system, using a widely used SysML authoring tool called MagicDraw. P&ID is one of the most critical output during the plant design phase, which contains all information required for the plant construction phase. So a SysML based P&ID has a great potential to enhance the communication among plant engineers of various disciplines.
