건설프로젝트는 현장여건의 변화와 불확실성으로 신뢰성 높은 계획을 수립하기 힘들고 따라서 건축시공시뮬레이션 시스템의 도입으로 그러한 문제점을 해결하고 신뢰성 높은 계획을 수립하려는 노력을 보이고 있다. 그러나 현시점의 시뮬레이션 시스템은 단순 애니메이션 용도로만 사용되고 실제 엔지니어링 업무를 지원하는 경우도 드물다. 최근 들어 이러한 한계점을 탈피하고 보다 시뮬레이션 시스템을 보다 적극적으로 사용하기 위한 연구와 개발이 이루어지고 있다. 하지만 BIM의 가장 핵심이 업무 효율성이라는 점에서 이러한 BIM기반 건축시공시뮬레이션시스템 등의 BIM기반 시스템은 성능 분석이 매우 필요한 요소라고 판단된다. 본 연구에서는 이를 위하여 시뮬레이션의 핵심 업무 프로세스를 정의하고 표준 시나리오를 정의하여 이를 기준으로 성능을 분석하는 방법론을 제시함으로써 좀 더 효율적이고 적극성을 갖춘 시뮬레이션 시스템 개발을 가능하게 하고자 한다.

It is important to identify informative variables in high dimensional data analysis; however, it becomes a challenging task when covariates are contaminated by measurement error due to the bias induced by measurement error. In this article, we present a two-step approach for variable selection in the presence of measurement error. In the first step, we directly select important variables from the contaminated covariates as if there is no measurement error. We then apply, in the following step, orthogonal regression to obtain the unbiased estimates of regression coefficients identified in the previous step. In addition, we propose a modification of the two-step approach to further enhance the variable selection performance. Various simulation studies demonstrate the promising performance of the proposed method.

Manufacturing companies' cost competitiveness with respect to equipment management can be achieved by satisfying additional market demands by their own capacity without purchasing additional equipments. In essence, it can be accomplished by making continuous investigation into bottlenecks and improvement on them. Therefore, equipment performance measure systems should be designed so that they can support manufacturing companies' such endeavors. With the purpose of establishing an effective equipment performance measurement system for detecting and improving bottlenecks, this study (1) suggests some desirable features that such a system should have, (2) evaluates conventional equipment performance measurement systems in terms of their usefulness for the detection and improvement of bottlenecks, and (3) proposes an improved system. We also perform a simulation experiment to demonstrate the limitations of the conventional systems and show how the proposed system can resolve the problems.

In this study, the performance of the DPRMs is evaluated and the measurement precision for the pile driving is presented. The DPRMs is a visual-measurement system for the pile rebound and the penetration movement using a high speed line-scan camera. But the measurement errors of the DPRMs are caused by the strong impact for the pile driving. Therefore, the DPRMs should guarantee its measurement values for the pile driving. For this reason, the performance of the DPRMs by the vibration signal analysis is studied. It is found from this study that the measurement values of the DPRMs are reliable.

The influence factors on the development of information technology(IT) infrastructure for knowledge management(KM) were not empirically investigated and identified. This study empirically examines the relationships among strategic performance measurement systems(SPMS), organizational learning, the strategic alignment of business strategy with information systems(IS) strategy, which is the necessary condition to provide the kinds of knowledge required for the successful realization of business strategy, and the active construction of IT infrastructure for KM. This study demonstrates that SPMS directly affects the organizational learning, with which the members of an organization acquire the types of knowledge about strategic goals or objectives and the ways attaining these goals, and indirectly influences the IS strategic alignment through organizational learning. Thus, the alignment between business strategy and IS strategy can be facilitated and activated by the adoption and implementation of SPMS. According to the results of this study, it is observed that the IS strategic alignment and organizational learning positively affect the activation of the development of KM IT infrastructure in a firm. The results of this study also shows that the construction of KM IT infrastructure, which supports the realization of KM activities, such as knowledge creation, transfer and sharing, can enhance the strategic position of a firm, and the intensified competitiveness of a firm can lead to the improvement of performance.

This study investigates the general applicability of the measurement scale for assessing channel-member performance for the supplier's view that was proposed by Kumar, and Achrol (1992). First, we attempted to examine whether the measurement-scale could be used without any change; the results from the initial data-analysis proposed that the scale needed a certain amount of a revision for further utilization. It seemed that the scale needed some adjustment for being applied to this study; their scale was developed with the data collected from the network of independent dealers handling multiple product items or multiple brands in the U.S. and Canada, while the data of this study were provided by a Korean car manufacturer having a dealer network selling and servicing only its own brand without ownership. Accordingly, we determined that it was necessary to develop a newly finalized performance-measurement scale revising Kumar et al.'s. During the data-analysis of the data resulted in a scale of fifteen items measuring three facets-financial performance, behavioral performance, and competence, each of which consisted of five items respectively. This empirically developed scale looked more valid for the situation of this study than the Kumar, Stern, and Achrol's which was composed of twenty-one items measuring seven facets--three items each.
