| Abstract | The primary goal of the systems engineering is the creation of a setof high quality products and services that enable the accomplishment of desiredtasks and needs of the clients or user groups. A typical systems engineering projectcan be divided in to three phases: definition, development, and deployment. Thedefinition phase involves the activities of requirement elicitation and refinement.By the end of system definition phase, we have all the system functional and nonfunctionalrequirements. One of the results of development phase is initial workingmodel of the system. The deployment phase consists of activities of operationalimplementation, operational testing and evaluation, and operational functioning andmaintenance. In a project life cycle there are numerous issues to be sorted out duringthe various phases to finally deliver a successful product. We proposed solution tothe problems of requirements engineering & management, design conflict detection,and stakeholders conflict resolution. This thesis is based on the recent advances inindustrial practices and research in the field of system design engineering.The objective of this thesis work is to propose an innovative and holistic conceptionmethodology taking into account the multidisciplinary environment and multiplestakeholders. We have proposed a requirements modeling language based on theGORE techniques. We have proposed a few of tools for reducing the ambiguity ofrequirements such as: using negation and test cases using negation for contractingdifficult requirements. Requirement management techniques are proposed to providebetter requirements traceability and aid for other systems engineering activities.Few guidelines have been designed to guide the design of traceability policies. Criteriaweighting technique has been designed to better carry out the conflict resolutions,during the various life cycle stages. Using the same criteria weighting technique aflexible multi criteria multi participant decision methodology is proposed for variousdecision problems arising during the life cycle of systems engineering project.Finally, a comprehensive prescriptive systems engineering approach is proposedusing all the previously made contributions and an illustrative case study of a realongoing project is presented developed using the supporting tool SysEngLab, whichimplements majority of the methods and techniques proposed during thesis. |
