Productivity is the most important factor directly link to success and failure of a work in construction industry. To evaluate this productivity, simulation technique is verified as a fine inspection tool through various experiment reports. On this project, we have proved the part of improvement on productivity using this simulation technique, applied to this field sites. We have used CYCLONE, which is the most appropriate simulation technique on this project. As a result of Simulation analysis, it has been confirmed that the productivity was enhanced due to the advancement of equipment, hence the reduction of air is being effected.

This study takes a statistical approach to quantify tile impact of wort stopped on the following day's site productivity. Therefore, this study is aimed to verify this null hypothesis: 'A work stopped in a construction field does not impact on the following day's productivity and productivity achievement ratio'. For the purpose, work, stopped is presumed as a dummy variable impacting site productivity in multiple linear regression analysis. Moreover, the quantified impact of work slopped on productivity achievement ratio is identified based on this study. This study shows that construction managers should persevere in their efforts to secure the work continuity in order to improve site productivity and productivity achievement ratio.

최근 농장을 방문하여 책임자 분들과 얘기를 하다보면, "육용종계의 생산성이 예전 같지가 않다." "수정율이 떨어진다."라는 말을 많이 듣게 된다. 종계의 생산성과 수정율 문제는 여러 가지 원인이 있겠지만, 그 중에서도 수탉관리를 통해 그 문제점을 해결해보고자 한다.

Recently, Construction market is contracted by economic slump and regulation. As the solution of this plan, construction productivity is gathering strength. However, the study on the productivity in construction section is insufficient until now. Construction section has many factor about productivity. The point of this study, we analysis the factor of construction productivity improvement and relationship with system thinking. And we show the strategy of construction productivity improvement.

Effectiveness of Just in time managing system can be obtained by removing unexpected lead-time and maintaining consistency on the physical transportation of construction resource. Construction resource management is essential on checking on load data from production of shop to field, and it is based on building resource life cycle information. In this study, production, transportation, and assembly disciplines of concrete construction should real time communications exchanging information related to shop-field with each other, Establishing information support system is an important initial step for promoting active cooperations among these resource life cycle on data flow. To achieve this, on suitable using management point, we suggest a concrete construction control model.
