최근에 ISO/IEC 9126과 ISO/IEC 14598에 기반한 소프트웨어 품질 평가는 다양한 분야에서 넓게 받아들여지고 있다. 그러나 소프트웨어 품질에 대한 이러한 표준들은 소프트웨어 제품에 대한 품질 모델과 품질 평가 프로세스의 실제적인 활용을 위한 지침을 제공하고 있지 않다. 그리고 대부분의 소프트웨어 사업에서 품질관리는 이러한 표준을 적용하기보다는 결함사항을 관리하는 방식으로 수행되고 있다. 그래서 본 논문에서는 국방 CBD 방법론의 산출물에 대한 정량적 품질 평가 방법을 제시한다. 특히, 본 논문에서 제시된 방법은 대부분의 표준 품질 평가 프로세스를 허용하면서 소프트웨어에 대한 이해관계자들에게 신중하게 작성된 설문서를 제시하여 얻어진 자료를 AHP 기법을 통하여 분석된 품질특성의 중요도를 이용하는 정량적 품질 모델을 적용한다. 또한, 소규모 소프트웨어 사업에서 얻어진 국방 CBD 방법론의 산출물에 대하여 품질평가 점검표를 적용하여 제안된 방법을 시험하였다. 결과적으로 제시된 방법은 고품질 소프트웨어를 획득하는 것이 가능함을 확인할 수 있었다.

This paper suggests the product supply process model based on the store and production capacity, assortment planning and quick response for fast fashion retailers with BPMN. In the fast fashion industry, the standardized business process model is required to respond quickly market trends and customer requirements based on the quantitative and qualitative criteria. Thus we define the product supply processes which incorporate forecasting and assortment plan, cost and profitability of the production, store capacity based on the visual merchandising, and production capacity of the fast fashion retailers. Also we design the key performance indicators to evaluate the effectiveness of these product supply processes. The product supply process model for the fast fashion has great significance in embracing the fast fashion product development process because it presents the holistic view of the product supply process of the fast fashion and provides a performance evaluation mechanism. A case study shows that adopting the processes, a Korean fast fashion company achieves improvement in various performance indicators.

Construction accidents occur reiteratively in similar fashions. There have been several attempts to develop a safety program for preventing construction accidents on sites. It will be very effective to use previous accident cases for establishing proper safety plan and managing safety process. This research develops a case-based construction safety management system which enables construction managers or safety managers to prevent potential accidents during the construction process. The case-oriented approach is performed through the representation of previous accident cases in accordant with the similarity to the conditions of current site. It uses a case-based reasoning which is one of the reasoning methods of an expert system. A prototype system for the reasoning model was implemented using one of the case based system development tools. The system was applied to a real construction site to verify its capability and validity. It was founded that the causes of accidents were successfully removed, so the proposed model proved to be reasonable. Additional research is needed to resolve the technical problem how to adapt the countermeasures for accident prevention provided by the reasoning model.

Model-based test, a well-known method of the black box tests, is consisted of the following four steps : model construction using requirement, test case generation from the model, execution of a SUT (software under test) and detection failures. Among models constructed in the first step, state-based models such as UML standard State Machine are commonly used to design event-based embedded systems (e.g., weapon control systems). To generate test cases from state-based models in the next step, coverage-based techniques such as state coverage and transition coverage are used. Round-trip path coverage technique using W-Method, one of coverage-based techniques, is known as more effective method than others. However it has a limitation of low failure observability because the W-Method technique terminates a testing process when arrivals meet states already visited and it is hard to decide the current state is completely same or not with the previous in the case like the GUI environment. In other words, there can exist unrevealed faults. Therefore, this study suggests a Extended W-Method. The Extended W-Method extends the round-trip path to a final state to improve failure observability. In this paper, we compare effectiveness and efficiency with requirement-item-based technique, W-Method and our Extended W-Method. The result shows that our technique can detect five and two more faults respectively and has the performance of 28 % and 42 % higher failure detection probability than the requirement-item-based and W-Method techniques, respectively.

In order to alleviate the environmental pressure caused by production process of thermal power plants, the application of cleaner production is imperative. To estimate the implementation effects of cleaner production in thermal plants and optimize the strategy duly, it is of great significance to take a comprehensive evaluation for sustainable development. In this paper, a hybrid model that integrated the analytic hierarchy process (AHP) with least squares support vector machine (LSSVM) algorithm optimized by grid search (GS) algorithm is proposed. Based on the establishment of the evaluation index system, AHP is employed to pre-process the data and GS is introduced to optimize the parameters in LSSVM, which can avoid the randomness and inaccuracy of parameters' setting. The results demonstrate that the combined model is able to be employed in the comprehensive evaluation of the cleaner production in the thermal power plants.

새로운 개발 패러다임으로 컴포넌트 기반 소프트웨어 개발이 소개되었다. 이 접근방식은 재사용 가능하면서 독립적인 단위의 컴포넌트들을 기반으로 소프트웨어를 개발하기 때문에 기존의 소프트웨어 개발 방식과는 차이가 있다. 따라서, 컴포넌트 기반 개발(CBD)은 크게 두 단계인 컴포넌트 개발 프로세스와 컴포넌트 조립 프로세스 즉, 어플리케이션 개발 프로세스로 구분된다. 컴포넌트 개발 프로세스는 컴포넌트가 품질 좋은 소프트웨어를 위한 열쇠이기 때문에 컴포넌트 기반 소프트웨어 개발에서 핵심적인 부분이라고 할 수 있다. 현재 이와 관련하여 학계 및 산업체에서 많은 방법론이나 도구들이 소개되고 있다. 그러나, 이러한 방법론이나 도구들은 실제 컴포넌트 개발 프로젝트에 손쉽게 적용할 수 있을 정도의 체계적이면서 유연한 모델링 기법들을 제시하고 있지 못하고 있다. 또한 현존 기법들은 컴포넌트 모델링에 있어서 독단적인 기법을 갖고 있거나 혹은 경험적 지침 정도만을 제공하고 있는 수준이다. 그 결과 많은 컴포넌트 개발자들이 컴포넌트 모델을 어떻게 개발해야 할지, 언제 어떠한 다이어그램을 개발해야 할지 등에 대한 어려움을 직면하고 있다. 본 논문에서는 이러한 문제를 해결하기 위해 메타 모델 기반의 접근법을 제시하고자 한다. 특히 계층과 개발 단계에 따른 메타 모델들을 제시하고자 한다. 이로써 개발자들은 적절한 시기에 적합한 모델들을 개발할 수 있게 된다.

Decision problem called an optimal release policies, after testing a software system in development phase and transfer it to the user, is studied. The applied model of release time exploited infinite non-homogeneous Poisson process. This infinite non-homogeneous Poisson process is a model which reflects the possibility of introducing new faults when correcting or modifying the software. The failure life-cycle distribution used superposition which has various intensity, if the system is complicated. Thus, software release policies which minimize a total average software cost of development and maintenance under the constraint of satisfying a software reliability requirement becomes an optimal release policies. In a numerical example, after trend test applied and estimated the parameters using maximum likelihood estimation of inter-failure time data, estimated software optimal release time. Through this study, in terms of superposition model and simply model, the optimal time to using superposition model release the software developer to determine how much could count will help.

Information systems quality engineering is one of the most problematic areas in practice and research, and needs cooperative efforts between practice and theory [Glass, 1996]. A model for evaluating the quality of system development process and ensuing success is proposed based on information processing theory of project unit design. A nomological net among a set of quality variables is identified from prior research in the areas of organization science, software engineering, and management information systems. More specifically, system development success was modelled as a function of project complexity, system development modelling environment, user participation, project unit structure, resource availability, and the level of iterative nature of development methodology. Based on the model developed from the information processing theory of project unit design in organization science. appropriate quality metrics for each variable in the proposed model are matched. In this way, a framework of relevant systems development and success quality metrics for controlling systems development processes and ensuing success is proposed. The causal relationships among the constructs in the proposed model are proposed as future empirical research for academicians and as managerial tools for quality managers. The framework and propositions help quality manager to select more parsimonious quality metrics for controlling information systems development processes and project success in an integrated way. Also this model can be utilized for evaluating software quality assurance programmes, which are developed and marketed by many vendors.
