Plan for passage decision of elevators using fuzzy measurement of personal area

We herein define two fuzzy sets using the personal fuzzy real number contained luggage as measured by a camera in an elevator system. Almost full elevators can decide pass the hall with longer queuing length compared a space of elevator car using the maximum decision probability approach (MDPA). Moreover, we progress the MDPA to the approach with an expected total effective thing (utility) function which is obtained using the action mode influence and effective thing analysis (AMIEA) like failure mode effect analysis (FMEA). Finally, we propose a variable λ-level fuzzy decision making approach using the concept of utility analysis.
