The objective of this paper is to provide the conceptual selection framework of SLA metrics to maximize the operation efficiency and satisfaction of IT outsourcing and how to select most efficient auto service call center and system. With these metrics, both customers and service providers can measure service performance of IT outsourcing service. Hence, it is expected to boost operation efficiency and customers' satisfaction. In that sense, this study gives the value to both outsourcing and outsourced companies through suggesting the proper SLA metrics selection framework which provides the standards of service performance measurement and the management of IT outsourcing service in accordance with their business strategy quantitatively and qualitatively. Also we perform a survey for two customers in real business to prove the logicality of this selection framework is working and to find out relationship between SLA practice and customers' satisfaction while they outsource their IT service.

In logistic environments, a process, in that it manages the flow of materials among partners, involves more than one organization. In this regard, a logistic process, as a combined process consisting of multiple sub processes, needs to be managed with controling interaction among partners. In achieving systematic management of a logistic process, traditional Business Process Management (BPM) cannot be used for the entire flow, since it lacks the ability to manage interactions among partners. Particularly in logistic environments where RFID technologies are used, how to deal with the connection between RFID event and logistic flow has not been properly addressed. To overcome this limitation, this paper proposes a new method of managing multi-organizational logistic processes based on RFID events. We define inter-workflow pattern, and suggest ECA(Event-Condition-Action) rules for auto triggering of logistic processes. To adjust the rules to RFID events, we invent RFID-based ECA rules using complex event. A prototype system has been developed for the purpose of demonstrating the effectiveness of our approach.

Continuous development of Personal Computer(PC) combined with the decrease of price and the expansion of operating system in PC like Windows 95, and Windows N/T makes it possible for the user to consider PC-bas-ed Automated Happing/Facilities Management (AM/FM) system. Therefore, the purpose of this study is to establish a PC-based data automation system of pipe infrastructures-water, sewer, and drainage-and road in Korea Land Corporation. In order to achieve this goal, relevant literature survey was done first. Secondly, the study site was determined by discussion with Korea Land Institute. Thirdly, PC-based CAD software for AM/FM in the world market were surveyed, and AutoCAD Map was selected because KLC had been using hundreds of AutoCAD copies already. After that user needs assessment was done to visit on-site office, local branch office, and the corresponding city office for the system design and database design. After the graphic data were digitized and the attribute data were entered into the batabase, the data automation system was established, and tested for application. Finally, the guidelines and problems for PC-based data automation in AM/FM was discussed.

Current MEP designs are mostly applied by 2D-based design methods and tend to focus on simple modeling or geometry information expression such as converting 2D-written drawings into 3D modeling without taking advantage of the strength of BIM application. To increase the demand for BIM-based MEP design, geometric information, and property information of each member of the 3D model must be conveniently linked from the phase of the Design Development (DD) to the phase of Construction Document (CD). To conveniently implement a detailed model at each phase, the detailed level of each member of the 3D model must be specific, and an automatic generation of objects at each phase and automatic detailing module for each LOD are required. However, South Korea's guidelines have comprehensive standards for the degree of MEP modeling details for each design phase, and the application of each design phase is ambiguous. Furthermore, in practice, detailed levels of each phase are input manually. Therefore, this paper summarized the detailed standards of MEP modeling for each design phase through interviews with MEP design companies and related literature research. In addition, items that enable auto-detailing with DYNAMO were selected using the checklist for each design phase, and the types of detailed methods were presented. Auto-detailing items considering the detailed level of each phase were classified by members. If a DYNAMO algorithm is produced that automates selected auto-detailing items in this paper, the time and costs required for modeling construction will be reduced, and the demand for MEP design will increase.

This paper deals with the critical role when adjustments of the regression model parameters play in forecasting. It attempts to formulate a methodology or systematic procedure for (1) detecting the points of adjustments and (2) finding the adjusted regression model parameters. The paper shows how the information of past experience in forecasting can be used future forecasting.

본 연구는 turbine compressor airfoil의 측정 및 검사 업무에서 edge(leading edge/trailing edge) 부위에서 자주 발생하는 프로브 slip현상으로 인한 측정 오차를 최소화하기 위하여 터빈 압축기의 airfoil 형상 규격에 대하여 살펴보고, 균일 샘플링방법을 이용하여 최소제곱법으로 보상하여 최적의 형상을 구하는 방법을 제시하고자 한다. 국내 기업에서는 airfoil형상의 edge부위를 검사할 때 leading edge부위의 타원 형상과 trailing edge부위의 원 형상을 AutoCAD상에서 임의로 그려서 규격을 검사하고 있다. 따라서 본 연구에서는 edge부위에서 발생하는 측정오차를 최소화하기 위하여 보다 정확하고 체계적인 fitting 방법을 도입함으로써, airfoil의 형상치수에 관한 규격검사 업무의 신뢰성과 효율을 향상시키고자 한다.

Environmental factors for automotive consist of temperature, humidity, vibration(sine & random), gas, an electrical load and so on. These environmental factors are impressed in a automotive. Dependability is essential requirement in many electronic parts. Among components of automotive, the connector connecting electrical signals is one of the most important parts. Automotive -connector is inspected according to each manufacturer's test standard in which dependability should be considered. This paper aims to verify that current test standard is suitable for dependability, and present an inductive life test for automotive connector based on the field data in use-condition.
