Main concerns of IT project managements are concentrated on the output control and process management. IT project, however, is difficult to measure the quality of achievement, because it produces invisible and intangible outputs. Many studies have been carried on to quantify the intangible aspects of process management. However, most of them have been focused on the technological aspects. This study measures the priority of factors to manage IT project by applying the IT-BSC and PMBOK method. Established indexes include the factors of managerial, social and future-oriented perspectives to check the different aspects of project management over the technical factors. This study uses AHP method for quantitative measurement. This study can be meaningful because of following reasons. First, this study re-arranges IT project management evaluation indexes by balanced scorecard. Second, this model includes human factors of developers and users who are directly related to the project development and operation. Third, important items of each stakeholder have been separated, and the weights of each item have been quantified to have fixed values.

기업은 날이 갈수록 심화되는 경쟁 환경에 대비하기 위해 많은 공급업체들과의 협력관계를 점차 강화해나가고 있다. 정보기술이 발전함에 따라 기업들은 SCM (Supply Chain Management)을 도입하여 이를 실현해나가고 있는 추세이다. 이에 따라, 공급사슬상의 관련 기업간의 상호작용과 정보공유에 기반한 공급사슬 통합이 추진되고 있으며, 정교한 관리를 위해 프로세스 간의 통합을 통해 하나의 글로벌 프로세스로서 SCM을 관리할 필요가 대두되고 있다. 이러한 관점에서 프로세스를 하나의 객체로서 관리하는 BPM (Business Process Management)을 활용하여 SCM을 체계적으로 관리할 필요가 있다. 그러나, 지금까지의 BPM은 비즈니스 프로세스의 자동화 및 통제 등에 주력해왔기 때문에, 전체 프로세스 관점에서 이를 효율적으로 실행하는 기능을 제공하지 못하고 있다. 따라서, BPM을 통해 SCM 프로세스를 단순히 자동화하여 실행한다면, 각 참여 업체들이 글로벌 프로세스의 관점에서 효율적으로 업무를 수행하기 어렵다. 본 논문에서는, 각 공급업체들이 전체 프로세스 관점에서 효율적으로 업무를 수행하는 방법을 제안한다. 제안한 방법을 통해 각 업체들은 전체 프로세스 내 관련 경로의 긴급도 및 관련 업무의 우선처리순위 정보를 제공 받을 수 있다. 따라서, 관련 정보를 토대로 각자의 업무를 수행하기만 하면, 글로벌 SCM 프로세스의 효율성을 향상시킬 수 있을 것이다.

This paper design and implements a synchronized agent mechanism that be able to synchronize SFT (Slow Frequency Transaction) data among e-business processes in distributed environment. This synchronized agent system is adopted to use mobile agent to guarantee the interoperability of the distributed processes and to solve some problems at the client/server architecture and proposes a policy to synchronize data of e-business processes on the any platforms of distributed heterogeneous systems. The proposed synchronization policy is based on the time-stamp transaction with the system priority on the unicasting transportation.

Some process algebras were applied to enterprise business modelling for formal specification and verification. ${\pi}$-calculus and mobile ambient can be considered for the distributed and mobile, especially to represent the movements of distributed real-time business processes. However there are some limitations to model the movements: 1) ${\pi}$-calculus passes the name of port for indirect movements, and 2) mobile ambient uses ambient to synchronize asynchronous movements forcefully. As a solution to the limitations, this paper presents a new process algebra, called ${\delta}$-calculus, to specify direct and synchronous movements of business processes over geo-temporal space. Any violation of safety or security of the systems caused by the movements can be indicated by the properties of the movements: synchrony, priority and deadline. A tool, called SAVE, was developed on ADOxx metamodelling platform to demonstrate the concept.

The existed approaches to analyzing real-time schedulability take place exponential time and space complexity of this methods, since these uses a fixed priority scheduling and/or traverse all possible state spaces. This paper judges whether it is satisfied a given deadlines for real-time processes regarding a minimum execution time of process, periodic, deadline and a synchronizion time of processes by using the transaction rules of process algebra, and proposes a retrieval algorithm for unschedulable processes based on GUI environment. And we implement and evaluate the scheduling state analyzer that displays visually the result of schedulabiliy analysis for real-time processes.

Statechart는 상태 기계를 기반으로 하는 정형 명세 언어로 반응형 시스템의 행위를 상태와 그 상태에서 받는 이벤트에 의한 전이로 표현한다. 프로세스 알제브라의 한 종류인 ACSR은 이벤트 기반으로 프로세스들 간의 통신과 프로세스의 우선 순위, 자원 소모 등의 표현 이 용이한 정형 명세 언어이다. 본 논문에서는 서로 다른 관점의 명세를 하는 이 두 가지 언어가 서로를 보완하여 ACSR을 이용하여 Statechart의 공유 자원에 대한 사용과 제어를 표현하여 보다 시스템을 정확하게 명세할 수 있는 언어를 제시한다. 이를 위해 두 언어의 연결을 위한 정형적 문법과 의미를 제시한다.

There is a wide variety of data quality attributes such as the ones proposed by the ISO/IEC organization and also by many other domestic and international institutions. However, it takes considerable time and costs to apply those criteria and guidelines to real environment. Therefore, it needs to define data quality evaluation attributes which are easily applicable and are not influenced by organizational environment limitations. The purpose of this paper is to derive data quality attributes and order of their priorities based on customer requirements for managing the process systematically and evaluating the data quantitatively. This study identifies the customer cognitive constructs of data quality attributes using the RGT(Repertory Grid Technique) based on a Korean quality standard model (DQC-M). Also the correlation analysis on the identified constructs is conducted, and the evaluation attributes is prioritized and ranked using the AHP. As the results of this paper, the consistent system, the accurate data, the efficient environment, the flexible management, and the continuous improvement are derived at the first level of the data quality evaluation attributes. Also, Control Compliance(13%), Regulatory Compliance(10%), Requirement Completeness(9.6%), Accuracy(8.4%), and Traceability(6.8%) are ranked on the top 5 of the 19 attributes in the second level.

The container ports have been increasingly changed according to the industry structure and differentiated customer's needs. So it seems to need the differentiated service strategies to have their competitiveness. To assess the customer requirements objectively, this paper associated the service process of container ports with the service quality scale by using the Quality Function Development(QFD). This paper analysed the service process of Busan port and then compared it with those of Shanghai port and Tokyo port which are the typical port of the northeast asia. Also, after drawing the importance of the service process as well as its priorities by representing the relation between service quality scale and processes of the container ports, this paper proposed the House of Quality(HOQ) for service quality improvements.

Several approaches to anlayzing real-time schedulability have been presented, but since these used a fixed priority scheduling scheme and/or traverse all possible state spaces, there take place exponential time and space complexity of these methods. Therefore it is necessary to reduce the state space and detect schedulability at earlier time. This paper proposes and implements an advanced schedulability analysis algorithm to determine that is satisfied a given deadlines for real-time processes. These use a minimum execution time of process, periodic, deadline, and a synchronization time of processes to detect schedulability at earlier time and dynamic scheduling scheme to reduce state space using the transition rules of process algebra. From a result of implementation, we demonstrated the effective performance to determine schedulability analysis.

Recently, companies have interests in the adoption and diffusion of customer relationship management(CRM). And, as information and communication technologies and Internet technologies proliferate, they also have interests in e-CRM, which implements CRMusing online communication channels. Until now, many researchers have tried to identify the success factors of CRM and evaluate their relative importance. However, only a few studies have dealt with the success factors of e-CRM. For this reason, we aim at identifying and evaluating the success factors of e-CRM in order to provide the companies with the guideline for preparing the implementation of e-CRM. Our study adopts analytical hierarchy process(AHP) as a tool for evaluating these factors because it has been widely applied and validated for a long time. Whereas prior studies have analyzed the success factors from the organizational and technological perspective, our study analyzes them from the functional perspective. As a result, we found that the companies should manage all the CRM components including analytic-operational-collaborative CRM in good balance. Also, we found that the sufficient support from CEO, the acquisition of good quality customer data, and theonline processing capability for responding customers' requests effectively are important for the success of e-CRM.
