The object of this research is to develop a computerized algorithm of cost estimation method to forecast the total construction cost in the bidding stage by the historical and elemental work cost data. Traditional cost models to prepare Bill of Quantities in the korea construction industry since 1970 are not helpful to forecast the project total cost in the bidding stage because the BOQ is always constant data according to the design factors of a particular project. On the contrary, statistical models can provide cost quicker and more reliable than traditional ones if the collected cost data are sufficient enough to analyze the trends of the variables. The estimation system considers non-deterministic methods which referred to as the 'Monte Carlo simulation. The method interprets cost data to generate a probabilistic distribution for total costs from the deficient elemental experience cost distribution.

With the size of construction projects getting larger and more complex, the amount of information is increased exponentially. Although there are a lot of construction companies that try to accumulate as-built information from construction sites. it has not been quite satisfactory. This is due to the lack of task information framework that can measure project performance and collect as-built information. Therefore the objective of the paper is to identify the information that can be derived from daily reports and to suggest a unit task information framework to accumulate as-built information.

본 연구는 국내에 있는 한 금융사에서 사용하고 있는 기존 인사평가시스템을 사례로 하여 시스템 운영자와 사용자(모든 임직원)가 시스템을 효율적으로 운영하고 사용할 수 있도록 인사평가시스템을 재구축하였다. 새로 구축될 인사평가시스템의 효율을 보다 높이기 위해 인사평가 업무와 평가 절차를 분석하고 그러한 평가체계를 기존 legacy 시스템(인사평가시스템)에 어떻게 반영이 되었는지도 분석하였다. 해당 금융사는 기존 평가시스템을 통하여 임원과 직원뿐 아니라, 비정규직원까지 년마다 상반기와 하반기로 나누어 업적과 역량평가를 각각 두번씩 실시하고 있었다. 평가결과는 나중에 보상이나 승진 시에 중요한 고과자료로 활용하고 있었다. 업적과 역량평가 뿐만 아니라, 신업사원을 대상으로 하는 정규직 수습평가와 계약직을 대상으로 한 역량평가 그리고 전직원이 대상인 다면평가도 실시하고 있었다. 그런데 여러 해에 걸쳐 인사평가를 실시하는 과정에서 평가프로세스가 여러 차례 변하였고, 많은 평가대상자를 평가하다 보니 예외적으로 처리해야 하는 경우도 발생하였다. 이런 변화와 예외적인 사항을 기존 Lagacy시스템에 반영하다 보니 평가데이터를 관리하는 테이블이 처음보다는 많이 늘어나게 되어 현재 약 170개에 달하고 있었다. 이렇게 많은 테이블 중에는 당시에는 사용했으나, 현재는 사용하지 않게 된 것도 포함되어 있었다. 프로그램 소스도 마찬가지로 새로운 요구사항과 많은 예외사항 처리로 인해 복잡해지고 프로그램 소스의 수도 늘어나게 되었다. 이로 인해 평가시스템 담당자는 시스템을 관리하기가 복잡해지고, 새로운 변화나 요구사항에 대응하기가 어려운 사항이었다. 그리고 담당자가 시스템 관리에 더 더욱 어려움을 겪게된 것은 시스템 담당자가 여러 번 바뀌는 과정에서 인수인계에 제대로 이루어 지지 않게 되었고 인사평가시스템 관리문서도 시스템 변화에 따른 히스토리 내용이 제대로 관리되지 못하고 있었기 때문이다. 그래서 이번 연구에서는 기존 legacy 시스템의 테이블과 프로그램 소스를 분석하여 방만하게 늘어날 데이터 관리 테이블을 효율적으로 줄이고, 예외적인 사항을 새로운 인사평가시스템에서 포괄적으로 수용할 수 있도록 재설계하였다. 또한 인사평가시스템 운영중에도 사용자(임직원)들로부터 있을 수 있는 예외적 요구사항을 미리 예측하여 운영담당자가 신속하고 정확하게 대응 할 수 있도록 하였다.

To effectively maintain manufacturing collaboration, the development of effective performance measurements for the collaboration is required. Most existing key performance indicators however were developed to measure the performances of internal activities or outsourcing of a company. For that reason, it is necessary to devise new key performance indicators that the partners participating in the collaboration can arrange and compromise with each other to reflect their common goals. In this paper, we propose collaborative Key Performance Indicators(cKPIs), which is used to measure the collaboration work of multiple manufacturing partners on the basis of the Supply Chain Operations Reference(SCOR) model. Also, a modified Sigmoid function is devised as a desirability function to reflect the characteristics of Service Level Agreement(SLA) between two partners. The proposed indicators and the desirability functions can be utilized to perform and maintain the successful collaboration by providing a way to the quantitative measurement.
