The developed computerized decision support system analyzes the effects of alternative improvement strategies on various project goals. Potential improvements to the system include rehabilitation and replacement of existing facilities, reconfiguration of the system with gravity-delivery pipelines, increased water storage, on-farm improvements, managerial improvements and various combinations of each of these singular alternatives. Project goals include technical measures of increased adequacy, efficiency, dependability and equity of water delivery, as well as non-technical measures such as relative cost, social acceptability, institutional acceptability and environmental impact. The technical measures of system performance are analyzed using the MODSIM river basin network flow model and fuzzy membership functions. The non-technical measures of system performance are analyzed using either ordinal scales or ratio scales that are developed interactively with the project decision makers. Each performance measure is weighted to allow more importance to be placed on certain performance measures over others. A multicriteria decision analysis is then used to develop an aggregate ranking of each alternative based on the system performance ratio/scale and weighting. The final product gives decision makers a ranking of alternatives which can be used to identify desirable projects for future study.born digitalCD-ROMsproceedings (reports)engCopyright and other restrictions may apply.
