Network analysis applications in energy management systems play a key role in the economic and reliable operation of power systems. In order to provide operators with useful network information, the accurate results of topology processing, state estimation, power flow, and contingency analysis must be simulated. This paper proposes a validation methodology of network analysis applications in energy management systems. The energy management systems was checked to ensure that it meets the originally specified functions based on the proposed methodology. In addition, the performance of state estimation is evaluated with the reference of the proposed methodology. The proposed methodology is being conducted by energy management systems and the Korean power systems have been utilized for the test systems.

Nowadays, the modeling of information systems have been enabled by various models and methodologies that are used for different purposes and perspectives upon the systems. The integrated modeling methodology that integrates these models and methodologies has become important concerns in system integration such as CIM and PDM. The primary objective of this paper is to propose a comprehensive integrated modeling methodology that integrates the OOIDEFO function model, OOIDEFO information model, node model, user interface model, and organization model for an effective analysis, design and implementation for system integration. This methodology covers the generic requirements of modeling methodology such as graphical notations, modeling processes, and abstraction mechanisms. Also, this methodology uses an 00 paradigm throughout the entire systems development life cycle. In order to prove the consistency and efficiency of the proposed methodology, the CIMS for ship production is modeled and prototyped.

This paper presents a formalism-based methodology and its implemented environment which constitutes a sound framework for real-time systems development. The software and/or hardware systems developed in such a formal manner are well structured and maintainable. We first propose a set-theoretic VSSS (Variable Structure System Specification) formalism. This formalism is the core of the presented methodology which supports a means of formal specification for real-time systems. We then develop the environment, including VSSS language definition, a translator for the language, and supporting libraries for real-time execution. Finally, a demonstration of the methodology in development of a real-time event manager, a subsystem of an ATM-based communication system, shows the correctness and efficiency of the methodology.

A decrease in the fertility rate leads to a reduction of troops, so the need to efficiently operate the troops is growing. Therefore, it is necessary to develop a system for estimating warship manpower. In this study, system development was performed according to the CBD methodology. The user requirements were defined and the system function that satisfies the requirements was derived. And through the development process, the CBD methodology and the systems engineering process were compared. As a result, similarities were confirmed in the analysis and concept design stages, so the possibility of merging the two processes was suggested.

Recently, most of the information system use environment is changing to GUI environment based on windows and web. Most of the development tools for building such a GUI-based information system support object-oriented and event-driven programming concepts. However, there is still a lack of a development methodology that systematically supports event-based information system construction. From a business perspective, an information system is one that supports business processes efficiently and effectively to improve business performance. These business processes are composed of business activities which involve a series of business events. A business event is executed according to a business scenario. Therefore, it is necessary to grasp these events in the requirements analysis stage and to apply it on the system development methodology. However, information systems development methodology which systematically reflect the event processing concept still is insufficient. From this viewpoint, this paper proposes an event-driven scenario-based development methodology that can meet the recent development environment of information systems, and applies the proposed methodology to a small scale information system development case.

The primary purpose of this study was to investigate a robust search methodology that could be used in full-text information retrieval systems. A robust search methodology is one that can be easily used by a variety of users (particularly naive users) and it will give them comparable search performance regardless of their different expertise or interests In order to develop a possibly robust search methodology, a fully functional prototype of a fuzzy knowledge based information retrieval system was developed. Also, an experiment that used this prototype information retreival system was designed to investigate the performance of that search methodology over a small exploratory sample of user queries To probe the relatonships between the possibly robust search performance and the query organization using fuzzy inference logic, the search performance of a shallow query structure was analyzes. Consequently the following several noteworthy findings were obtained: 1) the hierachical(tree type) query structure might be a better query organization than the linear type query structure 2) comparing with the complex tree query structure, the simple tree query structure that has at most three levels of query might provide better search performance 3) the fuzzy search methodology that employs a proper levels of cut-off value might provide more efficient search performance than the boolean search methodology. Even though findings could not be statistically verified because the experiments were done using a single replication, it is worth noting however, that the research findings provided valuable information for developing a possibly robust search methodology in full-text information retrieval.

A methodology is often used in solving complex problems. As a typical case of complex problem solving, development of information systems mostly requires a use of system development methodology. However, it is not always easy or smooth for organizations to adopt the methodology and to achieve a positive outcome from their application in real project situations. Although there are a few studies to find out success factors in the implementation of the methodology, they did not take into consideration essential characteristics of the methodology. This study aims to analyze the quality of the methodology as a key determinant to influence the performance of the methodology application.

We propose a new generic design methodology for different types of PSS. Product - Service System (PSS) has received much attention recently from academia and industry because of its benefits. PSS can provide customers values and functionalities, as well as physical products, to fulfill economic, social and environmental goals. Many methodologies have been proposed for designing PSSs. Most of the existing methodologies are domain specific and were proposed to solve specific problems in certain projects. Some methodologies are generic but they provide neither guideline to practitioners and designers nor reflect the differences in various PSS types. As a generic approach to guide practitioners and designers in designing PSS effectively, the proposed methodology also takes into account user involvement, business model and organizational structure. The proposed methodology is demonstrated through design examples of different types of PSSs.
