This paper is analyzed of the characteristics of development operations and development security operations of the software and product, and the use analysis tools from a software code perspective. Also, it is emphasized the importance of human factors and the need to strengthen them, when considering security design rules. In this paper, we consider a secure process for managing change, focusing on fast and accurate decision-making in terms of procedural factors, when considering development security operations. In addition, the paper discussed the need for maturity model analysis in relation to the development security operating characteristics, and analyzed the meaning of the analysis elements through detailed procedures for the strength and integration elements of the dynamic and static elements accordingly. The paper also analyzed factors such as scanning activity and code analysis for threat modeling and compliance and control.

In this study, an improved method of setting the RAM goals for surveillance system using OMS/MP and field operations data of similar systems is suggested and a case study of surveillance system A is given. Newly suggested methods for setting the RAM goals consist of the procedures such as On/Off time analysis of configuration equipment based on OMS/MP, field operations data analysis of similar systems, adjustment of preventive maintenance time, the number of corrective maintenances, and TALDT in wartime, introducing new subsystem to reliability structure of surveillance system, and reflecting expert's opinion. A case study of surveillance system A shows that newly suggested method in this study for setting the RAM goals is reasonably acceptable and practically applicable to other similar systems.

Reusing software is a promising solution which overcomes the software crisis in the software development environment by improving the software productivity, reliability and maintainability. To develop software, some developers reuse existing softwares, but without an adequate design environment, software reuse would not be applicable. The purpose of this paper is to design and implement the X system, and measure empirically its resuability in the development phases. The development processes of the X system used a software reuse design guidelines within the Object-Oriented Design method and the Ada programming language. In order to measure the resuability, metrics was proposed and applied for each phase of development. The results of this paper address some reusability measurement that may be used as basic data when estimating the amount of reuse for a combined development project of military applications.

Petri Nets are a graphical and mathematical modeling and promising tool for describing and studying that are characterized as being concurrent, asychronous, dynamic, distributed and parrallel. The purpose of this paper is to analyze FMS Throughout-Rate by development of Petri Nets So, it applied to FMS composed of 7 machines and 4 different job types. The result of this paper shows the advantage of using Petri Nets.

During the whole product design and development processes, the concurrent engineering relies on strong and permanent interactions between the departmental functions. Concurrent or simultaneous engineering in new product development is a new concept which needs to be redefined. This paper deals with a concurrent engineering model which represents how concurrency, as an organizational process, is related to a interfunctional project team. Four dimensions shaping the sucess of the concurrent engineering are suggested with detailed meausrement instruments. Moreover, an empirical study on the effects of the four dimensions on the efficiency of the product development processes is carried out in the field of electronic industries.

This paper proposes a framework for product development including hardware and software components. The framework provides separation of the hardware dependent software, an integrated product development process, and integration of software components with product configurations and product structures. In order to separates the hardware dependent software, the framework considers product configuration modules and engineering changes of associated hardware and software components. The proposed product development process integrates development of the hardware dependent software into the existing product development process. In order to integrates the hardware dependent software with product configurations and product structures, the framework represents software components by existing product data models in Product Data Management (PDM). The framework is applied to development of a robot system including hardware and software components in order to show its effectiveness.

Even though there are some studies on the deep drawing process and process planning, little study has been done on the methodology of process planning of secondary operations of deep drawing such as 'piercins'. In this paper, first, we systematized the methodology of the process planning of secondary operations on axisymmetric cup. Second we described the development of the expert system for their CAPP For these studies, we extracted the knowledge of their process planning from experts and analysed and systemized them. To develop the expert system, rule-based reasoning paradigm is used. The shape information of manufacturing features of secondary operations are manually input to the system through SUI. The process planning results are automatically connected to AutoCAD. We believe that the systematized process knowledge and the development of the expert system for its CAPP could give lots of aids to the associated field.

In this study we propose a technology selection model, which captures technology seeds for new business area by a fuzzy structural modeling method and then, design a model, which evaluates the validity of New Business Development plans for the selected technology seeds with regard to the properties of manufacturing, product, market, and economy as well. Finally, a fuzzy inference system is designed in order to decide the degree of success of New Business Development plans based on the preceding validity evaluation.

Demand for new information services is ever increasing as information technology advances in an unprecedented pace. Capabilities of information technology to overcome the time and space limitations enables efficient storage and processing of a large volume of data shared by many users in geographically dispersed areas. As the users ask for more useful information services, it is necessary to develop information services tp meet the needs of users. Enhancing information services is also necessary to cope actively with the pressures to open the information service is also necessary to cope actively with the pressures to open the information and telecommunications market as the level of Korean information services industry is still in its infancy. Value Added Network(VAN) services have a tremendous growth potential and its economic and social impact would be great as the information society matures. This study suggests a direction for the development of value added and new-media services based on the survey of individual and business users of information services.
