To reform and improve the productivity of construction industry, 1) it should be encouraged to improve the construction production process and 2) it is required to enhance reliability of construction information based on the systematic thinking process. To promote the information reliability created during construction production process, Lean Construction Research Center(LRC2) is developing a supporting system to improve design/material supply/schedule management, functioning to efficiently manage the information created at construction production processes and developing a web based construction information system that provides result management/decision making support/knowledge based information services.

Higher productivity and less cost during the manufacturing process of ships are required to maintain international competitiveness of modern shipbuilding industries. The integrated hull/ outfitting/ painting scheduling(IHOP) process is a final point, where logistics are finally being integrated and upcoming schedules are made. Therefore, more profits are expected from IHOP by effective management. In this thesis, IHOP is proposed in order to solve how to choose block erection date with IHOP scheduling logic. The result of IHOP scheduling is highly advised to utilize fabrication, outfitting shops. A standardized operation and load of resource will eventually be applied in long-term time span point of view for this will make it easy to enable capacity planning and workforce planning. It is also expected to eliminate inefficiency in overtime work and efficiently utilize manpower in short-term.

In an era where construction projects are becoming increasingly large and complex, the Korean construction industry faces the challenge of implementing systematic and cohesive schedule management practices. This study initially delineates the concept of schedule management capabilities, systematically categorizing them into five distinct domains: law and regulations, requirements of project owners, capabilities of professionals and organizations, task capability, and the adoption of smart construction technologies for schedule management. Through a survey targeting industry professionals, this research assesses the perceived importance and the actual proficiency level in schedule management across these categories, employing an Importance Performance Analysis(IPA) to scrutinize these capabilities. The findings underscore the acknowledged significance of diverse aspects of schedule management, yet reveal discrepancies between the current proficiency levels and their perceived importance, pinpointing areas necessitating enhancement. Critical improvement needs identified encompass the planning of budgets for schedule management, development of regulations for assessing construction periods, deployment of specialized on-site staff for schedule management, and investment in advanced schedule management software solutions. Consequently, this study offers a nuanced analysis and strategic insights for enhancing schedule management practices, aiming to facilitate their effective implementation in the field.

The construction industry has complicated production processes with diverse disciplines and subcontractors, which is the major cause of lowered productivity. To solve this problem, multi-trade subcontract system is recently suggested. Some general construction companies have applied this method to some sections of work process. However, this is in the early stage of application. The purpose of this study is to define an integrated contract package for improving both contractor and subcontractor efficiency. First, this study recognizes construction company to need of multi-trade subcontract system. Finally, it suggests feasible activities which can be useful for a construction company to apply to this subcontract system.

In multiple apartment construction project, BCWS is a critical management factor and has a great influence on the success of the project. Due to the many apartment buildings & facilities which produce numerous activities, there are several problems in making out a time schedule of work as well as production and management of precise BCWS from the allocation of resources. In this study, actual condition survey was executed in terms of the calculation and the management of BCWS. This study propose better solutions for efficient calculation of BCWS through the analysis of the problems and standard schedule & progress curves.

The Ministry of Construction-Transportation released a plan about EVMS in 1993 in order to prepare measures for an efficient public construction project, and prepared an enforcement proposal concretely in June for 2000 years, and have enforce a public project by an example with a target. Therefore, accurate analysis and evaluation about field progress are required for efficient management of a building construction, and must be established building construction management system for fast action about a problem However, unified management cannot be consisting because a work progress system is different from details estimate system within a country. and There is not still a definite standard in progress measurement for an application of EVMS. A purpose of this study is to present an improvement about a problem of progress measurement for an application of EVMS. The contents of a study, inquired into a progress measurement method and a standard to use in the field of a public construction and private construction and Checks a problem and presented an improvement item necessary for and is as follows. $\circled1$ must establishes a control account and progress measurement standard. $\circled2$ must manage progress in a activity viewpoint. $\circled3$ must use an accurate CPM process management technique.

이 글에서는 공정시스템공학의 주요 연구분야를 설명의 편리를 위해서 분류하였으나 실제로 그 경제가 확실치 않는 경우도 많다. 예를 들어 설계가 끝난 후 최적 운전을 연구하다 보면 설계를 다시 수정하는 것이 좋은 경우가 생긴다. 이 때에는 설계와 운전을 동시에 고려하여야 한다. 한편 설계, 제어, 운전이 유기적으로 통합되어 종합적인 관리 시스템으로 발전하게 될 것으로 전망되며, 이러한 공정시스템공학의 핵심기술은 환경, 에너지, 전자재료, 생물화공 등 많은 새로운 산업으로의 확대 적용도 기대되고 있다.

Recently, a research of the urban regeneration has been performed very actively. This is one of the efforts to resolve various social and economic problems coming from the existing deteriorated building and facilities by new urban development or redevelopment. However, an urban regeneration has a characteristic to be unable to ensure the project performance due to the exposed numerous risks coming from the various and complex stake-holders, and its mega sizes. This paper proposes the method of risk performance index in order to improve an efficiency of performance measurement expanding to the risk view point from the existing integrated cost/schedule performance measurement. A risk performance index is compatible with the existing EVMS, and can make the performance measurement in 3 dimensions of the integrated cost/schedule/risk with 18 sub-indexes and variables.

본 연구는 연속 회분식 반응기(SBR) 공정에서 시계열 데이터 마이닝을 이용하여 공정에 사용된 기기의 고장 진단 알고리즘 개발에 대한 내용을 보여주고 있다. 공정에서 비정상적인 반응을 유발하는 장비 관리에 대한 연구는 폭넓게 수행되고 있지 않으므로, 이러한 장비 진단은 소규모 하$\cdot$폐수처리장을 무인자동화로 통합관리에 유용하게 적용될 수 있다. 본 연구에서는 진동신호를 이용하여 무인자동화를 위해 선행되어야 하는 공정기기의 공장진단에 관한 알고리즘을 개발하였다.
