Interval-Valued Spherical Fuzzy Analytic Hierarchy Process Method to Evaluate Public Transportation Development

Consensus creation is a complex challenge in decision making for conflicting or quasi-conflicting evaluator groups. The problem even more difficult to solve, if one respondents are non-expert and provide uncertain hesitant responses survey. This paper presents methodological approach, the Interval-valued Spherical Fuzzy Analytic Hierarchy Process, with objective handle both types of problems simultaneously; considering scoring synthesizing different stakeholder group opinions by mathematical procedure. spherical fuzzy sets superior other extensions flexible characterization membership function. employed incorporating makers’ judgements about functions set into model an interval instead single point. In paper, AHP method has been applied public transportation problem. Public transport development appropriate case study introduce new analyse results due involvement three classically groups: passengers, non-passenger citizens representatives local municipality. Data from real-world survey conducted recently Turkish big city, Mersin, help understanding concept. As comparison, all likenesses differences outputs have pointed out reflection picture computation same data. demonstrated analysed detail step-by-step description procedure might foment applications model.
