How sustainability assessments using multi-criteria analysis can bias against small systems

摘要: Multi criteria analysis (MCA) has emerged as a popular decision making tool in the water industry. However, there are some restrictions with the method and its practical application that can bias against smaller systems in relation to larger centralized alternatives. This paper specifically identifies these biases, in relation to small recycled water systems and suggests ways to account for the bias. This will aid in the fair and robust comparison of smaller alternatives in relation to larger centralized options.
