Group Decision Support System for Multicriterion Analysis A Case Study in India

چکیده
The selection of the best irrigation system is examined in the multiobjective context for a case study of Sri Ram Sagar Project, Andhra Pradesh, India. Eight performance criteria, on farm development works, environmental impact, supply of inputs, conjunctive use of water resources, productivity, farmers' participation, economic impact and social impact are evaluated for thirteen irrigation systems. Analytic Hierarchy Process (AHP) is employed to overcome the difficulties arising from the complexity, subjectivity and lack of group consensus in the evaluation of an irrigation system. Spearman rank correlation coefficient is employed to assess the correlation between different ranking pattern. Group consensus is achieved through Geometric ranking rule (multiplicative ranking). Studies revealed that AHP is quite accessible and conductive to group consensus building. Comparison of the results indicated that the methodology is quite versatile and can be used in any field of engineering and management with suitable modifications.

Uncertain and stochastic states have been always taken into consideration in the fields of risk management and accident, like other fields of industrial engineering, and have made decision making difficult and complicated for managers in corrective action selection and control measure approach. In this research, huge data sets of the accidents of a manufacturing and industrial unit have been st...
متن کاملAn application of principal component analysis and logistic regression to facilitate production scheduling decision support system: an automotive industry case
Production planning and control (PPC) systems have to deal with rising complexity and dynamics. The complexity of planning tasks is due to some existing multiple variables and dynamic factors derived from uncertainties surrounding the PPC. Although literatures on exact scheduling algorithms, simulation approaches, and heuristic methods are extensive in production planning, they seem to be ineff...
متن کاملA Model-Driven Decision Support System for Software Cost Estimation (Case Study: Projects in NASA60 Dataset)
Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...
