Construction process works in sequence order and there are many different software for managing project and activity. So, there are many limitations such as in the stage of activity data loss can occur, in each stage concurrent cannot operate in construction industry. In order to solve these problem, agents have to cooperate each other and they need to share of data. Therefore, the purpose of this paper is to develop a process model and the process model will be use in the future to make Construction Project Life-Cycle Management based on concept of PLM(Product Life cycle Management) in the manufacturing industry, CE(Concurrent Engineering) and BlM(Building Information Modeling)

Recently, in an attempt to overcome the defects of quiescent power shutdown system, smart quiescent power control system has been developed. However, due to its higher investment costs, feasibility evaluation must be conducted. While LCCA (Life Cycle Cost Analysis) model is useful to estimate net savings of alternatives that differ with respect to initial costs and operating costs, the environmental burdens are not considered. On the contrary, LCA (Life Cycle Assessment) model is suitable to assess environmental impacts associated with the stages of a product's life but it does not consider costs. In this study, a comprehensive analysis on the economic and environmental impacts of smart quiescent power control system is conducted by using LCCA and LCA model. In addition, sensitivity analysis is carried out to quantify accuracy of estimates.

In this study, the appraisal in record continuum theory is analyzed in conjunction with the appraisal in life cycle model. In order to understand the more fundamental implications of appraisal in electronic record environment, it is essential to analyze the appraisal inherent in record continuum theory. Record continuum theory can provide a theoretical basis for appraisal in electronic record environment in that it is a theoretical system in opposition of the appraisal based on life cycle model and dualistic records management system resulting from it. In particular, considering that the appraisal is a purposive act of seeking the meaning of records, the reinterpretation of the concept and meaning of records intended in record continuum theory enables us to derive the different appraisal logics than before. Therefore In this study, based on comparison with the appraisal based on life cycle model and the new record concept presented in record continuum, the appraisal in record continuum theory is analyzed focusing on three aspects.

The aim of the paper is systematically to organize the historical facts of financial IT development process through various tracking and proved knowledge, it is to propose the direction and the advanced frame of core-banking model in next generation for the year 2020s. To achieve it, this study variously analyzed the meaningful pattern of development process of financial IT by backtracking life-cycle of Core-Banking model and it presented new model of Core-Banking for the past 40 years. In research findings, the life cycle of financial IT system and core-banking model have been analyzed about 10 years and the longest model of life cycle is about 33 years. As a result, It proved to be desirable that the advanced frame of the Core-Banking model adds the functions of business hub and product life cycle management to basic frame of its existing model in the future. In addition, big bang development method of new next generation system must be sublated. Also, They need to be initiated more business-oriented than IT-oriented. Along with this, the financial IT should be developed into the convergence industry, and it needs to extend the systematization of Core-Banking model studies and more professionals. Finally, this study has arranged the financial IT development process in domestic and presents new frame through analyzing intensively the Core-Banking model for the first time Therefore, it can be contributed to serve the guideline regarding the direction in new next generation system.

A life cycle cost analysis model for public water supply systems should be different from the ones for other civil and architectural facilities as the operation and the maintenance cost of the water supply systems mainly come from the various mechanical systems and the pipeline systems of the collecting/treating/distributing facilities. This paper presents a cost classification scheme and a life cycle cost analysis model for public water supply systems. A value analysis (VA) procedure that is well suited for practical purposes is also presented. The presented life cycle model and the value analysis procedure were applied to a real world project, and this case study is discussed in the paper. The model and the procedure presented in this study can greatly contribute to the value-oriented design alternative selection, the estimation of the maintenance cost, and the allocation of budget for water supply system construction projects.

In this study, a model is developed based on Life Cycle Energy Analysis (LCEA) method with Genetic Algorithm (GA) to determine optimal diameter of Water Distribution System (WDS). For hydraulic analysis the EPANET2.0 program is linked with developed model, pipe-aging equation and pipe-breakage equation are built in to developed model to simulate pipe change through life cycle. The model is then applied to two sample WDSs for optimal energy design. After determining optimal diameter for each WDS, the total cost is calculated based on determined diameter and compared with well-known optimal diameter set of each WDS. Results show that optimal energy design of WDSs through the developed model can be an alternative option for optimal design of WDSs for reducing energy with lower in cost.

Recently, the demand on the practical application of life-cycle cost effective design and rehabilitation of bridges is rapidly growing in civil engineering practice. However, in spite of impressive progress in the researches on the Life-Cycle Cost (LCC), the most researches have only focused on the theoretical point but did not fully incorporate the critical issues for the practical implementation. Thus, this paper is intended to suggest a systemic integrated approach to the practical application of various LCC methodologies for the design and rehabilitation of bridges, For that purpose, hierarchical definitions of LCC models are presented to categorize the approach of LCC assessment applicable for the practical implementation. And then, an integrated LCC system model is introduced with an emphasis on data uncertainty assessment and user-friendly knowledge-based database for its successful implementation. Finally, in order to demonstrate the LCC effectiveness for design and rehabilitation of real bridge structures, illustrative examples are discussed.
