Systems Analysis of Water Distribution Networks

Engineering systems analysis has been presented as a process which integrates computer-based analytic methods into design practice. As described, it implies significant changes in the content of the engineering design process and the manner in which engineering design is executed. The engineering systems analysis method proposed overcomes many of the current limitations on the use of computer techniques and therefore appears to be a useful framework for systems design. Specifically, the process recognizes the multiplicity of objectives and criteria of evaluation, searches out the best design strategies and configurations by sensitivity analysis, and distinguishes carefully between the mechanical evaluation of the alternatives and the judgmental selection of the preferred design. This systems analysis methodology was applied to an actual design problem, the planning for the $1 billion Third City Tunnel for New York City.
