As the technology of information and communication has developed over recent years, an embedded system is applied in multiple industries and becomes more complicated. For this reason, embedded system development cost and time are also increased. For decreasing the cost and time, this paper suggests requirement evaluation method for concurrent development of an embedded system based on Discrete Event System(DEVS) Formalism. This paper proposes a method of describing the requirements specification in the form of DEVS atomic model. Also, the paper proposes the evaluator model that compares evaluation target system and the requirements model that is an implementation of requirement specification and proposes the evaluation method using them. In addition, we propose a method to utilize the requirement model created for requirements evaluation in the concurrent development process of the embedded system. As the case study, this paper proceeds requirement evaluation of Kinect depth data processing system.

Requirement management is an essential process that has a significant influence on the project success. Due to the evolutionary development nature of requirement, the effective management for requirement must include change process and configuration control. This paper describes how to implement effective requirement management process to the Korea Tilting Train eXpress development with the application of a model based systems engineering tool.

In this work, we first introduce two main approaches to writing requirements and then propose a method based on Natural Language Processing to improve requirement authoring and the overall coherence, cohesion and organization of requirement documents. We investigate the structure of requirement kernels, and then the discourse structure associated with those kernels. This will then enable the system to accurately extract requirements and their related contexts from texts (called requirement mining). Finally, we relate a first experimentation on requirement mining based on texts from seven companies. An evaluation that compares those results with manually annotated corpora of documents is given to conclude.

The research and development stage can improve the goal level of the project through systematic operation and management of systems engineering. The test evaluation tasks in the R&D process have a lot of connections with the system engineering in terms of requirement management, and the methodology for deriving the requirements when establishing the test evaluation items has been consistently required. In this paper, we propose the process of effectively establishing and using QFD (Quality Function Deployment), a tool to manage customer requirement, and drawing up HOQ (House of Quality) in the search and exploratory development stage of the self - propelled mortar project.

Needs of fuel's performance evaluation for the dual-cooled fuel pellet (annular shape) necessitate the irradiation test in the test reactor. Irradiation test rig for the HARARO reactor, which is a special-purposed equipment used for material, irradiation and creep test, must satisfy the operational requirement on the hydraulic characteristics and structural integrity. In this paper, pressure drop and flow-induced vibration test for the newly developed non-instrumented test rig were carried out using FIVPET as a out-pile evaluation test. The test results show that the new test rig satisfy the HANARO operational requirement with sufficient margin. The spectral response characteristics of the flow-induced vibration of the test rid were also discussed.

We develop the evaluation method of functional requirements for excavator design. The functional requirement of the product can be deduced from voice of customer. QFD method is used in order to convert customer requirement to functional requirement. The measure of information index is used to evaluate quantitatively the product quality characteristics. The correlation score between customer requirements and functional requirements and benchmarking score of competitors are basic data for the measure of information.

For improve level of information security, the necessity of evaluation and certification of Information Security System(ISS) in increasing. Evalustion and Certification Institute have evaluated ISS for risk prevention of information dysfunction in an advanced countries. But, the problem of the time and cost occurred when it is caused by with application of unlike evaluation criteria each other. The result of effort to solution, Common Criteria(CC) and Common Evaluation Methodology(CEM) is using for evaluation of ISS and mutual recognition. Evaluation participant is needed flexible and active interpretation of CC and CEM for an efficient evaluation preparation and performance.

The requirement verification is the integral part of the weapon system R&D to reduce cost and schedule. And, a systems engineering is an interdisciplinary engineering management process that evolves and verifies an integrated, life-cycle balanced set of system solutions that satisfy customer needs. Therefore, this study analyzes the national defense need and acquisition management process, investigates the systems engineering verification activity. Through the requirement verification example in terms of technical evaluation this study presented the requirement verification approach in the weapon system R&D.

Auditors' subjective opinions m audit activities weaken reliability in audit judgments. This paper suggests fixed quantity models through requirement priority for improving objective evaluation and priorities of requirements in information system audit. The value of requirements was evaluated based on customers' requirements with a premise that they are not in the same level. Furthermore, the audit objective judgments were enhanced to enable fixed quantity of subjective audit by subdividing detailed evaluation index of requirement priority standards into importance of service and function on orderers' perspective, and sectioning cost and schedule on contractors' perspective.
