Title:
APPARATUS AND METHOD FOR DISTRIBUTION PREDICTION
Document Type and Number:
Japanese Patent JP3822523
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete method for prediction for a distribution predicting apparatus.
SOLUTION: The left side of a distribution predicting circuit 10 is a circuit 25 for an event A and the right side is a circuit 26 for an event B, and the both are connected by an admittance element 19 having a resistance value Rab. Denoting the current number of persons of the event A as Va, the current number of persons of the event B as Vb, the admittance of the admittance element (e.g. the resistance element) 19 between the events A and B which is calculated from statistical data of temporal transition of a past distribution of persons as Yab (=1/Rab), temporal variation in the rate of an increase in the predicted number of persons of the event A as A(t), temporal variation in the rate of an increase in the predicted number of persons of the event B as B(t), the voltage value of a DC voltage source 14 of the event A as Va×A(t), and the voltage value of a DC voltage source 18 of the event B as Vb×B(t), a current Iab(t) flows to the admittance element 19 with switches 16 and 17 closed. The current Iab(t) flowing to the admittance element 19 is calculated to predict a flow of persons between the events A and B.
