The ICS, Intercom is the equipment which mixes and distributes the audio signal from other LRUs and plays the Voice Messages. Henceforth, it is of immense contributory importance to the pilots. Especially, the audio routing, which controls On/Off mode of each audio channel, is significant in executing a pilots' mission. But the audio routing process is quite complicated as it has the interface combination of many control signals. Underthecondition, the exceptional handling becomes difficult, which decreases maintainability and productivity. In the present work, to prevent such a situation, the author suggests amethodology,whichwillhavealower impact when the software is changed and provides high maintainability and productivity for audio routing processing.

Component-based software development (CBSD) is a method for building large software system by integrating previously-existing software components. Software development method using components has several advantages such that reducing time to delivery and development costs, and increasing productivity etc. But integrating components developed from multiple vendors is too difficult As a result it is required the understanding on the context of use to develop reusable components. The context of use for software component of determined by software architecture. Therefore, it is possible to develop an application based on components if is based on software architecture. Also, it is essential to consider domain concepts for CBSD. To increase the reusability of components. we should develop components in a domain which is a set of related systems. In this paper, we proposed a domain architecture development methodology that supports component-based software development. Domain architecture that represents components and their relationship is produced through domain analysis and design process. We believe that component development methodology using proposed domain architecture can efficiently develop highly reusable components as well as easily develop and application using information acquired from domain architecture.

Component-based development(CBD) has acquired a substantial acceptance in both academia and industry as an effective inter-organizational reuse technology. A component framework in product line engineering(PLE) which consists of related components, connectors and their semantics has a greater potential for reusability than components. In frameworks, components are glued with association, dependency and connections. Problems occur like affecting the implementation code of components when they are glued and replaced because the association and dependency relationships between COTS components which are acquired for application development do not match exactly. Especially, a connector may not only connect related components, but also mate partially-matched COTS components fit together. However, little has been studied to date about connectors that can be used practically. In this paper, we present a meta-model for connectors and show how a connector can be designed and implemented in practice. We propose five main patterns of connectors. Proposed major patterns Provide design guidelines for practical and efficient connector configuration based on component framework. And also, applying techniques and applied case studies of the major patterns show greatly increased applicability and reusability of the component without component modification.

It is well recognized that component-based development (CBD) is an effective approach to manage the complexity of modem software development. To achieve the benefits of low-cost development and higher productivity, effective techniques to maximize component reusability should be developed. Component is a set of related concepts and objects, and provides a particular coarse-grained business service. Often, these components include various message flows among the objects in the component, called 'business workflow`. Blackbox components that include but hide business workflow provide higher reusability and productivity. A key difficulty of using blackbox components with business workflow is to let the workflow be customized by each enterprise. In this paper, we provide techniques to model the variability of family members and to customize the business workflow of components. Our approach is to provide formal specification on the component variability, and to define techniques to customize them by means of the formalism.

This paper manufacturing one system and use this separatively, plan, and embody system that apply integration design method in research about characteristic of internal core of 8051 micro-processors and system reusability so that can use as module of other system. The proposed system itself by object style so that reusability may be possible in proposed method and object style for connection between this systems is required. Set on these request and when systems have own information and were linked with other systems, by supplying own information automatic movement itself is realized and system itself embodies ashes so that can be applied to other system. The proposed method in this paper analyzes and compares with existent Z-80 education board, as well as system that propose offers extensibility, it handles most function to software and development period, expense and baud dimension confirmed advantage of and so on that reduce. Also, design for object style system architecture and showed feature that extensibility and portability are augmented.

Component-Based Development (CBD) has emerged as a new effective technology that reduces development cost and time-to-market by assembling reusable components in developing software. The degree of conformance to standards and common features in a domain largely determines the reusability of components. In addition, variability within commonality should also be modeled and customization mechanism for the variability should be designed into components. Enterprise JavaBeans (EJB) is considered a most suitable environment for implementing components. However. the reusability of EJB is limited because EJB does not have built-in variability design mechanisms. In this paper, we present efficient variability design techniques for implementing components in EJB. We propose a method to customize the variability of EJB-based components by applying three variability design mechanisms; selection, plug-in, and external profile. And we elaborate the suitable situations where each variability design mechanism can be applied, and conduct a technical comparison to other approaches available.

The software which is used for electronic bulletin boards have shortcomings that the addition of new function and new information's type to the order point software is very difficult, and the aggressive adaption of newly introduced type of media is impossible because the software is developed by custom solution. Eventually new cost and time are required to enhance functionality or performance to software of DID(Digital Information Display). In this paper, we proposed the scheme to package DID's contents and to customize it using plug-in method. We conducted a case study of this scheme. The platform which can install Apps to DID as one of content was designed. Apps can be inserted by plug-in type on DID platform and run separately with DID framework. As a result, We got advantage that various contents, functions and Apps which are drived on Android can be displayed without any restriction and dependency because Apps itself is one of dynamic notice object. This solution increase reusability of Apps or contents, and can be used easily in various places such as airports, stations, terminals, and front desk by customizing.

As the most common application development of software development time, error-free quality, adaptability to frequent maintenance, such as the need for large and complex software challenges have been raised. When developing web applications to respond to software reusability, reliability, scalability, simplicity, these quality issues do not take into account such aspects traditionally. In this situation, the traditional development methodology to solve the same quality because it has limited development of new methodologies is needed. Quality of applications the application logic, data, and architecture in the entire area as a separate methodology can achieve your goals if you do not respond. In this study secure coding, the big issue, web application factors to deal with security vulnerabilities, web application architecture, design procedure is proposed. This proposal is based on a series of ISO/IEC9000, a web application architecture design process.

An important technical issue in recent software development is to make needed software by the composition of components that are assemblable, and configurable, and independently extracted. The main advantage of component-based software development is reducing development time and cost. It is more cost-effective in development time to use components that are already developed than developing from scratch. There are two ways of component-based software development: one is to compose self-developed components, and the other is to by the components developed by third-parties and compose them. In the second case, existing non component programs must can be used for reuse in the component development. In this paper, we approach two methods for increase of reusability of Java program. First, we suggest the technique of extracting the elements suitable for the Beans component model from Java program, and then we show a process and a guideline of converting the extract elements into the Beans component model. Second, we suggest a technique of automatically extracting component information from the Java Beans component, expressing them in XML, its is possible to reuse the efficient component environment.
