건설공사의 성공적인 수행을 위해서는 프로젝트의 성과에 대한 주기적이고 반복적인 측정 및 그에 대한 조치가 필요하다. 이에 비용, 일정, 품질은 프로젝트 성과 측정의 주요 대상이 되며, 비용 및 일정의 경우 정량화할 수 있고, 상호연관성이 높기 때문에 통합관리의 필요성이 매우 높다. 이러한 비용일정 통합관리를 통한 성과측정 방법이 바로 EVMS이며, 이러한 새로운 관리방식의 성공적인 국내적용을 위해선 그 관리 방법의 절차 및 의미가 명확히 인식되어야 한다. 이에 본 연구는 비용, 일정, 여유시간을 종합적으로 고려한 새로운 최적의 성과측정기준선(Performance Measurement Baseline)설정 및 진도율 산정 방법을 제시하고자 한다. 제시된 방법을 통해 비용 및 일정정보가 통합된 성과측정기준선이 마련되었으며, 진도율 산정에 있어서도 작업간 영향요소 및 공기지연가능성을 고려한 종합적인 작업별 가중치가 산정되었다.

With the introduction of supply chain management concept, the nature of a firm is fundamentally changed. Control is no longer based on direct control of the business processes, but rather based on integration across member organizations in the supply chain. Firms are trying to achieve a competitive edge by managing their supply chain performance to gain advantages in cost and service differentiation. The supply chain elements of a sea port involves ILSP (Inbound Logistics Service Provider) at the input side and OLSP (Outbound Logistics Service Provider) at the output side. The goal of sea port is to satisfy the needs of different parties, both upstream and downstream, in the chain with greater effectiveness and efficiency than it's competitors. In this context, the purpose of this paper is to derive conceptualization of the SCP (Supply Chain Performance) in the sea port from literature review on the previous researches and to tackle their theoretical and practical implications. The paper deals with conceptualizing SCP in sea port using the SCOR (Supply Chain Operation Reference) model. It incorporates both the effectiveness and efficiency aspects of performance measurement. And it also recognizes customer related reasons for measuring performance.

Because of both precise measurement and efficient quality control, coordinate measuring machines(CMMs) have been widely used in the industry. The purpose of this paper is to present a method to estimate the CMM measurement uncertainty using design of experiments. A factorial design is applied to carry out the performance test proposed by ISO 10360 and to investigate CMM measurement errors associated to orientation and length of the length bar. In order to assess the measurement uncertainty for the performance test, an analysis of the uncertainty components that make up the uncertainty budget has been carried out. The procedure for evaluating the uncertainty of it follows GUM ("Guide to the expression of uncertainty in measurement"). The results show that the proposed method is suitable to investigate CMM performance and determine the contribution of machine variables to measurement uncertainty.

The Quality of Experience (QoE) of next Generation wired/wireless network services based upon IP networking is becoming a popular issue in recent years. The user experience of Internet services such as IPTV, online game, web surfing and etc, are becoming the most desirable factors to service providers to improve service performance and customer's satisfaction. However, collecting user experience from customers and obtaining the QoE parameters from the Quality of Service (QoS) parameters such as bandwidth, delay, jitter or admission control algorithm, are difficult subjects because of the various service types and user characteristics. In this paper, we propose a framework which contains service classification, QoE analysis and service enhancement steps for a suitable QoE measurement and management protocol. We define the user satisfaction indicators of the Internet services, classify the categories of each type of services, and analyse the Key Performance Indicator (KPI) in each type of services to perform the QoS parameters and improving the service qualities.

In the manufacturing industry, there has been a significant increase in the use of coordinate measuring machines(CMM). In this paper, the sources of CMM measurement performance are discussed. The effects of workpiece position, length and orientation are analyzed by using the design of experiments. Both a fractional factorial design and a factorial design are employed to conduct the experimental study. The analysis of variance is performed to determine the significance of factors in the experiment and regression analysis is applied to make the measurement approximate model. The results show that position along the Z axis, length and orientation affect the CMM measurement performance.

Performance measurement is not an easy task. However, it is necessary to measure the expected value of the informatization project to be invested, to help the successful progress of the informatization project, and to confirm the result of the informatization project. This study describes the evaluation systems of the defense informatization project in Korea used after the end of the informatization project (post-implementation evaluation stage). In the post-implementation evaluation stage of proposed system, the informatization project is evaluated in terms of performance achievement, project plan compliance, project management, and economic validity. For each element, this study suggests metrics and practical measurement method. With metrics and their method, it can be evaluated which project is better than others. Moreover, the lessons learned can be developed. Under scarce budget condition, defense organizations can make better performance from IT project with the evaluation system suggested in this study.

Most organizations adopt their own performance measurement systems. Those organizations select performance measures to meet their goals. Organizations can give only limited description of what performance measures are. Kaplan and Norton suggest that the Balanced Scorecard (BSC) to complement the conventional performance measures. The BSC can provide management system with a comprehensive strategic vision and integrates non-financial measures with financial measures. The BSC is widely used for measuring corporate performance. This paper investigates how the BSC-based performance measures can be applied to Learning City. The Learning City's performance measures and strategy map on the basis of the BSC are suggested in this research. This paper adopt the AR(assurance region)-DEA model which could limit the range of weight on performance measures to prevent each viewpoint of BSC from having unlimited elasticity. The proposed model is based on CCR model including a property of unit invariance to use the data without normalization process.

건설기업의 경영성과는 제각기 다른 프로젝트들의 경영성과 합과 같으므로, 건설 프로젝트 수행에 따른 경영성과 측정은 기업 경쟁력 확보를 위해 필수적이다. 그러나 현재까지 대부분의 연구는 건설 산업 및 기업의 성과 측정과 관련되어 있으며, 개별 프로젝트의 성과 측정을 위한 연구는 여전히 미비한 실정이다. 특히 건축 프로젝트는 발주자, 형태, 사업주체에 따라 다양한 특성을 가지고 있지만, 이러한 구분에 따른 성과지표 선정은 이루어진 바없다. 따라서 본 연구는 건축 프로젝트의 시공 및 시운전 단계에서 공통적으로 경영성과를 측정할 수 있는 지표뿐만 아니라, 프로젝트 특성에 따라 세분화된 분야의 지표를 선정하는 것을 목적으로 한다. 향후 본 연구에서 제시한 지표들은 이를 평가할 수 있는 방법을 개발하고, 실제 건축 프로젝트에 적용하여 정량화된 점수로 산출이 가능할 것이다. 또한 플랜트 및 토목 프로젝트의 경영성과를 측정할 수 있는 지표 선정을 위한 참고자료로 사용될 것으로 사료된다.

Purpose: The purpose of this study is to investigate the design optimization modeling of screening procedures based on the assessment of misclassification errors. Methods: Misclassification errors due to measurement variability are derived for normally distributed quality characteristics. Further, an optimization model for ensuring the level of outgoing quality is proposed and demonstrated through an illustrative example. Results: It is shown that two types of misclassification errors (i.e., false acceptance and false rejection) may be properly compromised through an analytical assessment of measurement errors and an optimization modeling. It is also discussed that a variety of optimization modeling may be enabled based on the derivation of measurement errors. Conclusion: It may be concluded that the design of screening inspection may further be facilitated by including the effect of measurement errors on the performance of screening inspection procedure.

This paper proposes a R&D project performance measurement model for private firms combining balanced scorecard (BSC) and data envelopment analysis (DEA). The efficiency of R&D projects is measured in terms of each of the three perspectives of BSC by using DEA : the internal process perspective (DEA-P), the customer perspective (DEA-C), and the financial perspective (DEA-F). The performance indicators of the three perspectives of BSC are considered as outputs of the corresponding DEA models. To provide strategic implications for R&D planning, we also propose the R&D project performance matrices composed of two different types of efficiency dimensions. The proposed model is expected to be fruitfully utilized for R&D performance measurement of private firms.
