The requirement validation is vital for every successful software development. In this process, the requirements from the users are checks and analyzed with its consistency, completeness and correctness. The validation of requirements is a very vast research area in software engineering. In this presented article, some quality research approaches are cited for the software engineering researche...

A Virtual Organization (VO) consists of some real organizations with common interests, which aims to provide inter organizational associations to reach some common goals by sharing their resources with each other. Providing security mechanisms, and especially a suitable access control mechanism, which enforces the defined security policy is a necessary requirement in VOs. Since VO is a complex ...

This paper gives a pictorial view of the relevance of lean thinking, particularly the applicationof muda as a supplement to the sustainable improvement diagnosis technique of existing public office buildings,for a fuller assessment of users’ requirement in Nigeria. The impact of perceived muda was related to the triplebottom line of sustainable development on perceived job productivity and desi...

Requirement elicitation is an analysis, abstraction, synthesis, extracted process which obtains real and correct software requirements from users' demands, thoughts and expectations. The accuracy and integrity of software requirements is crucial to the success of the software. Although many software engineering techniques have been applied, incomplete, inaccurate or inconsistent requirements st...

In the requirement specification phase, several users express the same requirement. In fact, they are situated in different contexts. The context detection of such expressed requirement faces many problems. Among these problems, we cite the implicit aspect of a context. In this work, we propose an approach to detect the requirement context by expliciting this context notion with contextual para...

—In device-to-device (D2D) communication system, rational resource allocation can effectively reduce the interference between cellular users and D2D users. In this paper, based on the QoS requirement of cellular users and D2D users, we propose a channel allocation and power control optimization algorithm, which takes limit transmission power of each cellular user and total D2D users into consi...

Requirements in software development are fundamental in order to document and describe what the system to be developed basically “is” and how it should behave. The requirements are elicited, anlyzed and prioritized in the requirement process to produce a software requirement specification (SRS). The SRS can contain many requirements and large volumes of information, which calls for good require...

AbstructFor wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells. By effecting the lowest interference environment, in meeting a required minimum signal-to-interference ratio of p per user, channel reuse is maximized. Distributed procedures for doing t...

Nowadays the natural requirement of users is to retrieve the best answers for the criteria they have. To explain, what kind of objects user prefers, we need to know, which values of properties are suitable for the user. We assume that each property is possibly provided by an external source. Current algorithms can effectively solve this requirement, when the sources have the same ordering as th...

One of the existing problems in requirement engineering consists in arriving to capture final user requirements as well as possible. But it is clear that engineering methods such as goal-oriented models or system-oriented requirement diagrams such as SYSML are sometimes too hard for end-users. In this paper we define a systematic process allowing ennd-users to specify requirements using cogniti...
