플랜트 프로젝트의 성과 향상을 위해 EPC 업체들은 통합적 관점에서의 프로젝트 사업관리 방식 개발에 대해 지속적인 관심을 보이고 있다. 특히, Advanced Work Packaging (AWP)는 프로젝트 생애주기 관점에서 기존의 "작업체계" 개념을 통합하여 프로젝트 수행 방식을 일부 재조정하는 방식으로 사업성과 개선을 위한 방법으로 제시되고 있다. 그러나 아직까지 국내 EPC 업체들은 AWP 도입의 초기 단계로, AWP를 수행하기 위한 구체적인 연구가 부족한 실정이다. 이에 따라, 본 연구에서는 AWP 체계의 도입을 위해 EPC 기업에서 갖추어야 하는 조직역량 도출을 목표로 하였다. 문헌 고찰과 현직자 인터뷰를 통해 AWP 도입시 발생할 것으로 예측되는 주요 리스크를 도출하였으며, 맥킨지 7S 모델 체계에 맞추어 이를 방지하기 위한 29개의 조직역량 항목을 도출하였다. 이후 AWP 전문가 5인의 검증 과정에서 추가적으로 도출된 8개의 조직역량 항목을 반영하여 최종적으로 효과적인 AWP 도입을 위해 필요한 조직역량 37개를 도출할 수 있었다.

The project schedule risk in the engineering and facility construction industry is increasingly considered as important management factor because the risks in terms of schedule or deadline may significantly affect the project cost. Especially, the project-based operating companies attempt to find the best estimate of the project completion time for use at their proposals, and therefore, usually have much interest in accurate estimation of the duration of the projects. In general, the management of projects schedule risk is achieved by modeling project schedule with PERT/CPM techniques, and then performing risk assessment with simulation such as Monte-Carlo simulation method. However, since these approaches require the accumulated executional data, which are not usually available in project-based operating company, and, further, they cannot reflect various schedule constraints, which usually are met during the project execution, the project managers have difficulty in preparing for the project risks in advance of their occurrence in the project execution. As these constraints may affect time and cost which role as the crucial evaluation factors to the quality of the project result, they must be identified and described in advance of their occurrence in the project management. This paper proposes a Bayesian Net based methodology for estimating project schedule risk by identifying and enforcing the project risks and its response plan which may occur in storage tank engineering and construction project environment. First, we translated the schedule network with the project risks and its response plan into Bayesian Net. Second, we analyzed the integrated Bayesian Net and suggested an estimate of project schedule risk with simulation approach. Finally, we applied our approach to a storage tank construction project to validate its feasibility.

Modular integrated construction (MiC) is an innovative construction method where components of a building are manufactured in an offsite factory, trucked to the job site in sections, set in place with cranes, and assembled together to form a whole building. Where circumstances merit, favorable conditions exist and implemented effectively; MiC improves project performance. However, several key factors need to converge during implementation to realize the full benefits of MiC. Thus, a thorough understanding of the factors which are critical to the success of MiC projects is imperative. Drawing on a systematic review of 47 empirical studies, this research identified 25 key success factors (KSFs) for MiC projects. Of these, the five topmost cited KSFs for MiC projects include effective working collaboration and communication among project participants; standardization, optimization, automation and benchmarking of best practices; effective supply chain management; early design freeze and completion; and efficient procurement method and contracting. The study further proposed a conceptual model of the KSFs, highlighting the interdependences of people, processes, and technology-related KSFs for the effective accomplishment of MiC projects. The set of KSFs is practically relevant as they constitute a checklist of items for management to address and deal with during the planning and execution of MiC projects. They also provide a useful basis for future empirical studies tailored towards measuring the performance and success of MiC projects. MiC project participants and stakeholders will find this research useful in reducing failure risks and achieving more desired performance outcomes. One potential impact of the study is that it may inform, guide, and improve the successful implementation of MiC projects in the construction industry. However, the rigor of the analysis and relative importance ranking of the KSFs were limited due to the absence of data.

Construction is a collaborative endeavor. The complexity in delivering construction projects successfully is impacted by the effective collaboration needs of a multitude of stakeholders throughout the project life-cycle. Technologies such as Building Information Modelling and relational project delivery approaches such as Alliancing and Integrated Project Delivery have developed to address this conundrum. However, with the onset of the pandemic, the digital economy has surged world-wide and advances in technology such as in the areas of machine learning (ML) and Artificial Intelligence (AI) have grown deep roots across specializations and domains to the point of matching its capabilities to the human mind. Several recent studies have both explored the role of AI in the construction process and highlighted its benefits. In contrast, literature in the organization studies field has highlighted the fear that tasks currently done by humans will be done by AI in future. Motivated by these insights and with the understanding that construction is a labour intensive sector where knowledge is both fragmented and predominantly tacit in nature, this paper explores the integration of AI in construction processes across project phases from planning, scheduling, execution and maintenance operations using literary evidence and experiential insights. The findings show that AI can complement human skills rather than provide a substitute for them. This preliminary study is expected to be a stepping stone for further research and implementation in practice.

Global construction projects manifest more risks than do other industries. Often, firms doing business in construction markets find these risks intimidating. To secure corresponding profits, many global contractors attempt to forecast the effects of risks and establish risk management strategies. However, one key problem with present-day risk management methods is that they are basically analytical or mathematical-oriented approaches which are not easy to adopt in real business. Based on preliminary investigations and evaluations of current tools, this research elicits more practical algorithms for risk checklist by constructing risk scenarios over the whole period of project execution. For the application of the algorithms, a "SE/RF" (Source-Event/Regular-Floating) checklist is suggested, which sorts out risk sources and their subsequent events, as well as dividing various risk factors into either regular or floating categories. In addition, the "PIS" (Probability-Impact-Significance) method is introduced, in place of traditional "PI" (Probability-Impact) methods, by adding the additional criterion of "risk significance" to determine the degree of risk exposure in a more realistic way. As a result, we draw the significant finding that the "PIS" method presents a closer evaluation regarding degree of risk exposure as compared to the level of expert judgments than those from traditional methods. Finally, we provide an integrated procedure for international project risk management with all of the research achievements being incorporated.

Many companies have implemented ERP systems to enhance their process competitiveness. Since most ERP systems down to date are implemented and managed on each separated business-unit or company level, such systems run short of the consideration about global business processes and global system managements. In order to integrate a successful global ERP, it is essential to apply the well-systematic implementation methodology which considers global standardization and global IT requirements. It is, however, the actual circumstance that such well-structured methodologies for global ERP implementation are hardly shown not only from domestic site but from foreign one. This paper indicates the global ERP implementation guideline with integrated approach including; the standard process design for efficient execution of global business; the ERP implementation method considering global IT requirements; and, the management method for global system operation. GSI ERP methodology is composed of 3 Phase：Global Strategy Planning, Global Template Construction and Global Roll-Out. Phase1; Global Strategy Planning contains Environment Analysis, GSI direction and Implementation Plan. Phase2; Global Template Construction contains Business blueprint, GSI operation design and Global template implementation. Phase3; Global Roll-out contains local business analysis, local ERP implementation and Global ERP Operation.

국내 ESCO 사업은 에너지효율향상 제도 중에 하나로 1992년도에 도입되어 시행되고 있다. 현재 스마트그리드, 신재생에너지 등의 에너지시장 여건의 변화와 수요반응의 중요성이 부각되었다. 이에 사업 모델의 다양화 요구됨에 따라 해외 사례를 통한 국내 활용방안을 검토하였다. ESCO 산업이 활성화되었다는 유럽이나 미국에서의 사업영역은 에너지 공급 설비 및 공급 서비스부터 최종 사용자까지를 포함한 전 영역의 에너지 설비의 효율 개선 조치를 포함한다. 이런 ESCO 해외비즈니스 모델은 다양한 유형으로 구분이 가능함을 알 수 있으며, 그 유형을 프로젝트 수행방식, 공급자 수요관리, 파이낸싱의 방법, 기후변화 및 배출권 등, 신재생에너지, 에너지투자, IT연계관련, 신 ESCO사업, 기타의 기준으로 구분하였다. 본 연구에서는 각각의 비즈니스 사례 적용방안으로 국내에서도 IEC (Integrated Energy Contracting) 계약방식을 활용하는 것을 제안한다. 또한 에너지절약이라는 목표달성을 위해 개별사업유형의 나열함으로써 이를 허용하는 형태는 오히려 관련 시장 활성화를 가로막는 장애요인으로 작용하고 있는 바, 현행 에너지이용합리화사업을 위한 자금지원지침을 개정방안으로 투자사업 및 설치사업 모두를 포함하는 다양한 에너지절약사업을 대상사업으로 추가하되, 네거티브시스템(Negative system)의 도입을 제안한다.
