For several years, a research about the simulation for shipyard and shipbuilding has been performed. This research is based on the concept of PLM (Product Lifecycle Management) and DM (Digital Manufacturing). Global leading companies and research center are trying to get a good position of PLM, especially M&S field. Digital shipbuilding is to computerize shipyard facilities and shipbuilding processes, and to simulate expected scenarios of shipbuilding processes using a computer model in order to resolve a potential problem such as a bottleneck processes, and over loaded resources. In this paper, simulation methodology for shipbuilding is described. In addition, a local and global strategy for the use of simulation methodology is suggested. Finally, case studies about an indoor shop and an outdoor shop are described.

Software architecture is the blueprint for a software system and should provide consistent guidelines for design, implementation, and maintenance throughout the entire lifecycle of the system. Components, interactions between the components, well-formed structure, reasons, and various perspectives reflecting various stakeholders' concerns changing through the phases of software lifecycle are the key elements of software architecture. The architect identifies and engages the stakeholders, understands and captures stakeholder's concerns including those regarding life cycle, and lets the concerns reflected in the architecture. To do so, architect should take into consideration various contextual elements regarding the system too. We make an extended list of the elements, especially those of business application software architecture, that the architect should take into consideration and construct a model of the relationships between the elements.

The purpose of this paper is to examine empirically how to balance advertising expenditure before and after launch with regard to the direction of word of mouth in the motion picture industry. The vector auto-regression model is applied to assess the dynamic impact of advertising and word of mouth on sales. Empirical data, including advertising, word of mouth, and sales (the number of entries) of 83 movies are used for analysis. The research results show that for a movie having more positive word of mouth in the pre- and post-launch periods, it is worthwhile to spend the advertising budget in the pre-launch period only and to spare it in post-launch period. However, it is worthwhile to spare the advertising budget in the pre-launch period for movies having less positive word of mouth before and after launch, and to concentrate spending in post-launch period instead. Mangers who handle products and services facing shortened lifecycles, such as games, eBooks, and digital music contents, need to check the quality of pre-launch word of mouth for their advertising budget decisions in the pre- and post-launch periods and spend more of the advertising budget in the post- (pre-) launch period if pre-launch word of mouth is negative (positive). For products and services with a shortened lifecycle, it is recommended to spend more of the advertising budget in the post- (pre-) launch period if pre-launch word of mouth is negative (positive).

BIM (Building Information Modeling)은 토목 구조물의 3차원 객체모델을 기반으로 기획 단계부터 설계, 시공 및 유지보수 단계에 이르기까지 대상 구조물에 관련된 모든 정보를 통합적으로 생성, 관리하는 기술이다. 현재 국내외의 다양한 건설 산업 분야에서는 건설 생산성 향상을 위하여 BIM 기술을 도입하여 활용하고 있다. 그러나 이러한 BIM 기술을 적용하여 효율적인 엔지니어링 업무를 수행하기 위해서는 무엇보다 참여 주체간의 협업 시스템이 필요하다. 따라서 본 논문에서는 토목 프로젝트 참여 주체의 요구사항을 분석하여 건설 프로젝트 관리를 위한 BIM 기반의 CPLM (Construction Project Lifecycle Management) 시스템을 설계, 개발하였다. CPLM 시스템은 건설 프로세스 단계에 따른 정보의 관리와 공유가 가능한 환경을 제공한다. 향후 CPLM 시스템을 실무에 도입함으로써 기존의 업무 프로세스를 개선하고 데이터를 효율적으로 관리할 수 있게 되어 의사결정에 도움을 줄 수 있을 것으로 기대된다.

RUP(Rational Unified Process) 객체 지향적이며 사용사례 및 아키텍처 중심의 반복적인 개발방법론이다. 이전에 수행된 대부분 공공분야의 대규모 소프트웨어 개발은 폭포수형 개발 프로세스를 적용하였으나 최근에는 소프트웨어 개발에 따른 위험을 최소화 하고 품질을 향상하기 위하여 RUP와 같은 반복 개발방법의 적용을 시도하고 있다. 그러나 대규모 복합 체계의 개발 프로세스와 그 일부인 소프트웨어 개발 프로세스로서 RUP를 적용한 국내의 연구 자료는 미흡한 실정이다. 본 논문에서는 RUP를 기반으로 복합 체계의 일부인 소프트웨어를 개발하는 프로세스를 고찰하고자 한다. 이를 위하여 국내 CIS 소프트웨어 개발 사례를 통하여 체계개발 프로세스와 통합된 RUP프로세스를 제시하고 기존의 폭포수형 프로세스 및 RUP와 비교 경가론 한다. 된 논문의 연구결과는 공공기관에서 대규모 복합체계의 소프트웨어를 개발하는 경우에 RUP 기반 프로세스의 조정, 개발관리에 있어서 위헌의 최소화와 최종 제품의 품질향상에 기여한 것으로 믿는다.

Purpose: The purpose of this study is to propose an Integrated Safety Evaluation Process (ISEP) that can enhances the safety aspect of the safety-critical system. This process utilizes the advantages of the iterative Systems Engineering process combined with the safety assessment process that is commonly and well defined in many standards and/or guidelines for railway, aerospace, and other safety-critical systems. Methods: The proposed process model is based on the predefined system lifecycle, in each phase of which the appropriate safety assessment activities and the safety data are identified. The interfaces between Systems Engineering process and the safety assessment process are identified before the two processes are integrated. For the integration, the elements at lower level of Systems Engineering process are combined with the relevant elements of safety assessment process. This combined process model is represented as Enhanced Functional Flow Block Diagram (EFFBD) by using CORE(R) that is commercial modelling tool. Results: The proposed model is applied to the lifecycle and management process of the United States aircraft system. The US aircraft systems engineering process are composed of twelve key elements, among which the requirements management, functional analysis, and Synthesis processes are considered for examplenary application of the proposed process. To synchronize the Systems Engineering process and the safety assessment process, the Systems Engineering milestones are utilized, where the US aircraft system has thirteen milestones. Taking into account of the nine steps in the maturity level, the integrated process models are proposed in some phases of lifecycle. The flows of processes are simulated using CORE(R), confirming the flows are timelined without any conflict between the Systems Engineering process and the safety assessment process. Conclusion: ISEP allows the timeline analysis for identifying activity and data flows. Also, the use of CORE(R) is shown to be effective in the management and change of process data, which helps for the ISEP to apply for the development of safety critical system. In this study, only the first few phases of lifecyle are considered, however, the implementation through operation phases can be revised by combining the elements of safety activities regarding those phases.

The cost of software maintenance occupies about two thirds in the software lifecycle. However, it is not easy to estimate the cost of software maintenance because of various viewpoints about software maintenance, unclear estimation methods, and complex procedures. Until now, the cost estimation model has used compensation factors for software characteristic and environment on the basis of program size. Especially, most of existing models use maintenance rate of total software cost as a main variable. This paper suggests the software maintenance cost estimation model that uses the result of calculating real maintenance efforts. In this paper, we classify functional maintenance and non-functional maintenance as software maintenance activity type. For functional maintenance, present function point of target software is needed to evaluate. The suggested maintenance cost evaluation model is applied to a software case in public sector. This paper discusses some differences between our model and other modes.
