- FIG. 2 is a flowchart showing an outline of an assigned car determination procedure for a new hall call according to Embodiment 1 of the present invention
- FIG. 3 is a diagram for explaining the concept of a risk floor.
- risk floor candidates are first selected in step S201. This risk floor candidate selection will be explained using Fig. 3.
- Figure 3 shows the state that the # 1 through # 4 cars are moving from the 1st floor to the 10th floor.
- the # 1 car is UP on the 5th floor.
- the # 2 and # 3 cars are traveling in the Down direction on the 7th floor and in the UP direction on the 4th floor, respectively.
- the # 4 car is on the 1st floor in a door-open standby state. In this situation, assume that a new hall call in the Down direction occurs on the 9th floor.
- any number of floors may be selected as appropriate. Basically, it is determined based on the position and moving direction of each car at the time when a landing call is newly generated.
- the farthest floor (the so-called back floor) is selected for the arrival of the force.
- the back floors are selected for cars # 1 to # 3 that are running.
- the # 1 force is the 4th floor UP direction
- the # 2 car is the 8th floor Down direction
- the # 3 car is the 3rd floor UP direction.
- Car # 4 is in the door-open standby state, but if assigned to a new hall call, it will travel in the UP direction. Therefore, the # 4 car is assumed to be in the first floor UP direction, and the second floor Down, which is the farthest floor here, is selected as the risk floor candidate.
- each risk floor candidate is selected as described above, it is assumed that a hall call is temporarily generated on this floor for each risk floor candidate in step S202 and step S203 in FIG.
- the prediction calculation that calculates the arrival prediction to the assumed landing call floor when each force is assigned to the landing call of each risk floor candidate, and the evaluation value calculation based on the arrival prediction calculation result Do each.
- step S202 an arrival prediction calculation is performed.
- This prediction calculation is to calculate how many seconds each force can reach each floor.
- This procedure is disclosed in, for example, Japanese Patent Application Laid-Open No. 54-102745 (Patent Document 3), and has been widely implemented in the group management control from the past. Therefore, the procedure is briefly described here.
- an estimated arrival time table creation program is created in advance as follows, and the estimated arrival time calculated by periodically executing this program is stored, and when a hall call occurs. This is the one that will be memorized!
- Figure 4 is a flowchart of the predicted arrival time table creation program.
- the hall call, car call, and car status (car direction, car position, door open / close, travel status) required to create the predicted arrival time table Etc.) is loaded into a predetermined memory.
- 1 is set in the index register (step S401)
- an initial value that changes according to the state of the force is set in the time table
- the time table T is set in the estimated arrival time table (Ste S402).
- the initial value is different between when the car is stopped and when the car is running, and the initial value when the car is running is set to be smaller than the initial value when the car is stopped.
- step S402 the floor is then advanced by one floor (step S403), and it is determined whether the floor is at the car position (step S404). If the floor is not in the car position, the time required for traveling on the first floor (eg 2 seconds) is added to the time table T (step S405).
- this time table T is set in the estimated arrival time table (step S406). Then, it is determined whether or not there is a car call or an assigned hall call on the floor of interest (step S407), and if those calls exist, the process of step S408 is performed. That is, the time required for stopping the first floor (for example, 10 seconds) is added to the time table T. If there is no car call or assigned hall call in step S407, jump to step S403 and repeat the same process.
- step S404 if the floor is at the car position, an estimated arrival time table is created in the same manner for the next car. When all the cars are finished, this program is finished. As described above, the estimated arrival time table is created by scanning all floors, all directions, and all baskets.
- step S203 the evaluation value is calculated based on the calculation result of the predicted arrival time in step S202.
- This evaluation value calculation is performed, for example, by obtaining an evaluation function value such as the following equation.
- step S204 based on the evaluation value calculation results performed up to step S203.
- the risk floor is selected from the risk floor candidates selected in step S201.
- the evaluation value when the force is assigned is extracted. This value is the evaluation value Vr for the risk floor candidate r.
- V r m i n J, I)
- V (R) m a X V r
- the floor having the largest evaluation function value and the largest impact on the transport efficiency within the building, that is, the floor that is likely to generate long waiting is selected as the risk floor.
- the assigned car for the new hall call is determined by the procedure after step S205.
- step S205 and step S206 prediction calculation and evaluation calculation are performed when each car is assigned to a new hall call.
- the procedure of step S205 is basically step S20.
- step S206 is almost the same as the procedure in step S203. Assuming that a new hall call and a risk hall call occurred simultaneously, as shown in the following equation, The evaluation value is obtained for the case where it is assigned to the hall call.
- step S 20 When the evaluation values are calculated for all cases as described above, step S 20 is calculated.
- the thread combination (i, j) of the assigned car with the best evaluation function city (i, j) is taken out, and the assigned to the new hall call out of this assigned car combination (i, j). Decided to make the final allocation capacity for the i-car.
