FITradeoff Method for the Location of Healthcare Facilities Based on Multiple Stakeholders’ Preferences

Multiple stakeholders’ preferences are considered for solving a healthcare facility location problem in the city of Milan, Italy. The preference modeling is based on the Flexible and Interactive Tradeoff (FITradeoff), a Multicriteria Decision Making (MCDM) method used to elicit criteria scaling constants in additive models. FITradeoff is an easy tool for decision makers, because it requires them to exert less effort than other traditional elicitation methods, as the tradeoff procedure. Therefore, it is expected that fewer incon- sistencies will appear during the elicitation process. Sixteen criteria were used to evaluate in which of six potential areas a new hospital could be sited. An analyst with a strong background in MCDM interviewed four actors, and elicited their preferences with the help of the FITradeoff Decision Support System (FITradeoff DSS).
