Abstract: Systems’ Requirements Engineering
The primary goal of the systems engineering is the creation of a set of high-quality products and services that enable the accomplishment of desired tasks and needs of the clients or user groups. A typical systems engineering project can be divided into three phases: definition, development, and deployment. The definition phase involves the activities of requirement elicitation and refinement.
By the end of the system definition phase, we have all the system functional and nonfunctional requirements. One of the results of the development phase is the initial working model of the system. The deployment phase consists of activities of operational implementation, operational testing and evaluation, and operational functioning and
Maintenance. In a project life cycle, there are numerous issues to be sorted out during The various phases to finally deliver a successful product. We proposed a solution to the problems of requirements engineering & management, design conflict detection, and stakeholder conflict resolution. This thesis is based on the recent advances in industrial practices and research in the field of system design engineering.
The objective of this thesis work is to propose an innovative and holistic conception methodology taking into account the multidisciplinary environment and multiple stakeholders. We have proposed a requirements modeling language based on the GORE techniques. We have proposed a few of tools for reducing the ambiguity of requirements such as: using negation and test cases using negation for contracting difficult requirements. Requirement management techniques are proposed to provide better requirements traceability and aid for other systems engineering activities.
Few guidelines have been designed to guide the design of traceability policies. Criteria weighting technique has been designed to better carry out the conflict resolutions, during the various life cycle stages. Using the same criteria weighting technique a flexible multi-criteria multi-participant decision methodology is proposed for various decision problems arising during the life cycle of the systems engineering projects. Finally, a comprehensive prescriptive systems engineering approach is proposed using all the previously made contributions and an illustrative case study of a real ongoing project is presented developed using the supporting tool SysEngLab, which implements the majority of the methods and techniques proposed during the thesis.

This chapter briefly introduces the research work accomplished during the thesis.
The research works presented in this thesis were carried out in Laboratoire d’Analyse et d’Architecture des Systems of Center National de la Recherché Scientifique (CNRS-LAAS), Toulouse, France, with the research funding from Ministry of Higher Education and Research (MESR). The research was carried out with Ingénierie Système et Intégration (ISI) group, i.e., Systems and Integration Engineering group at LAAS-CNRS. ISI team works in the context of the design of complex systems by improving development life-cycle processes, particularly requirement engineering & management, modeling & simulation, verification & validation, and Safety Engineering, In a method, process, and tool vision. First, the background and motivation of this thesis are introduced. The primary research goal of the thesis, i.e., a comprehensive methodology for the design
In systems engineering is presented. Next, in order to achieve the primary goal, the primary research goal is divided into a set of three sub-goals: requirements engineering, requirements management & traceability, and decision-making.
The necessary technical objectives to achieve the sub-goals are identified and research themes necessary to achieve these objectives are determined. Next, a brief insight into the actual research themes is presented and their significance to the systems engineering is high-lightened. The research problems are identified and difficulty to address them is also discussed briefly. Finally, the structure of the thesis and the links Between the various chapters are presented.
The Kavian Scientific Research Association (KSRA) is a non-profit research organization to provide research / educational services in December 2013. The members of the community had formed a virtual group on the Viber social network. The core of the Kavian Scientific Association was formed with these members as founders. These individuals, led by Professor Siavosh Kaviani, decided to launch a scientific / research association with an emphasis on education.
KSRA research association, as a non-profit research firm, is committed to providing research services in the field of knowledge. The main beneficiaries of this association are public or private knowledge-based companies, students, researchers, researchers, professors, universities, and industrial and semi-industrial centers around the world.
Our main services Based on Education for all Spectrum people in the world. We want to make an integration between researches and educations. We believe education is the main right of Human beings. So our services should be concentrated on inclusive education.
The KSRA team partners with local under-served communities around the world to improve the access to and quality of knowledge based on education, amplify and augment learning programs where they exist, and create new opportunities for e-learning where traditional education systems are lacking or non-existent.
