この発明は並設されたエレベータを一群として管理する
エレベータの群管理装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator group management device that manages elevators installed in parallel as a group.
近年、エレベータの群管理は、乗場で呼びが登録される
と即時にサービスするエレベータを選択して割当てそれ
を表示する方式が主流となった。In recent years, the mainstream of elevator group management has become a system in which when a call is registered at a landing, the elevator to be serviced is immediately selected, assigned, and displayed.
エレベータを選択する基準として最も重要なのは待時間
を小さくすることであるが、サービスするエレベータを
表示する以上、その表示が狂わない事も重要である。し
たがって、評価基準の中に直接予報外れ率（割当てられ
たかごよりも他のかごが先に到着する確率）を入れた方
式もよく採用されている。The most important criteria for selecting an elevator is to minimize waiting time, but as long as the elevators being serviced are displayed, it is also important that the display does not go out of order. Therefore, a method that directly includes the forecast failure rate (the probability that another car will arrive before the assigned car) is often adopted as an evaluation criterion.
例えば、特公昭６１−３１７０８号公報によれば、ｊ号
機に乗場呼びを割当てたときの評価値ｒ」をＩｊ＝Σ
（ｔｋ２＋ Ａ−Ｐｋ）
ｍｌ
ここに、ｔｋ：乗場呼びｋの予測待時間Ｐｋ：乗場呼び
ｋのサービスかとよりも他のかごが先に到着する確率
Ａ：重み係数
Ｎ：登録されている乗場呼びの数
とし、Ｉ、の最も小さくなるかごｊ（ｊ＝１・・・８）
に呼びを割り当てる方式が記述されている。For example, according to Japanese Patent Publication No. 61-31708, the evaluation value r when a hall call is assigned to car No. J is expressed as Ij=Σ
(tk2+A-Pk) ml where, tk: Predicted waiting time for hall call k Pk: Probability that another car will arrive before the service of hall call k A: Weight coefficient N: Registered hall call Let the number of I be the smallest basket j (j=1...8)
The method for allocating calls is described.
しかし、Ａという重み係数を入れている事からも分かる
ように、全体の予測待時間（またはその２乗）を小さく
することと、予報外れ率を小さくすることは相入れない
ところがあり、Ａにより重視の程度を決めており、実際
の予報外れを検出してその頻度によりＡの値を変えるよ
うにしている。すなわち、予報外れが多ければＡを大き
く、少なければＡを小さくして待時間と予報外れのバラ
ンスをとっている。However, as can be seen from the inclusion of the weighting coefficient A, reducing the overall predicted waiting time (or its square) and reducing the forecast failure rate are incompatible; The degree of emphasis is determined, and the value of A is changed depending on the frequency of actual forecast deviations detected. That is, if there are many forecast errors, A is increased, and if there are fewer forecast errors, A is decreased to maintain a balance between waiting time and forecast errors.
しかしながら、上述した従来例では交通状況や予報外れ
状況などに応じて予報外れ率そのものの計算の仕方を変
えるようにしている訳ではないので、予報外れ率の予想
が現実と合っていない場合、待時間との重み付けを変え
ただけでは根本的な予報外れ減少の対策とはならないと
いう問題点があった。However, in the conventional example described above, the calculation method of the forecast failure rate itself is not changed depending on traffic conditions, forecast failure conditions, etc., so if the prediction of the prediction failure rate does not match the reality, the waiting time There was a problem in that simply changing the weighting relative to time was not a fundamental measure to reduce forecast errors.
この発明は、上記のような問題点を解消するためになさ

ある。The elevator group management device according to the present invention has a plurality of elevators installed, and when a hall call occurs, a forecast comprehensive evaluation value consisting of a linear sum of two or more evaluation factors is temporarily assigned to each elevator, and the In an elevator group control device that allocates the above-mentioned call to the elevator for which the forecast is optimal and makes a forecast, when a forecast failure occurs, a comparison means for comparing the above-mentioned forecast comprehensive evaluation value of a car for which the forecast was made and a car for which the forecast was missed; and a weighting coefficient varying means for varying the weighting coefficient of the evaluation element in a direction in which the comparison difference becomes smaller.

きる。In this invention, when a forecast error occurs, the overall forecast evaluation values of the car that made the forecast and the car that missed the forecast are compared, and the weighting coefficients of the elements that create the evaluation value are changed in the direction that the difference becomes smaller. By doing this, it is possible to more accurately determine the possibility that the forecast will be incorrect, so that the probability that the forecast will be incorrect for the elevator serving the hall call is reduced, and the passengers waiting at the hall can wait for the elevator with peace of mind.

The forecast comprehensive evaluation value is calculated according to the detailed flow shown in FIG. That is, in FIG. 4, first, in step 531, the first-come-first-served expected evaluation value PI^~ of the ANC machine is calculated.
Calculate PIG. The first arrival expected evaluation value PIA of Unit A is PIA = win (TYB, TYC) / TY
A Here, min (TYB, TYC) is the minimum expected arrival time of cars other than car A. TYA is the expected arrival time of car A [anticipated arrival time] = [number of stops to the 1st floor] number of stops] x 2.

となる。Next, in step S32, car call occurrence evaluation values P2A to NP2G for each car are calculated. The car call occurrence evaluation value is 1.0 if there is a car call on the floor currently being considered (first floor), and 1.0 from the floor where the call is located if there is an assigned call in the down direction up to the first floor. It is assumed that a car call occurs on the floors between the two floors with a probability of 0.1, and that a car call on the first floor is calculated by subtracting the sum of the probabilities that a car call occurs on the above floors from 1. In addition, in cases other than the above, considering that when a car is stopped due to a car call, a person going to the first floor may board the car, the probability that a car call will occur on the first floor per stop is set to 0.1. Applying the above calculation to Fig. 2, the evaluation value P2^ of the occurrence of the collision of car A is as follows: P2A= 1-0.1 x 3 = 0.7 The evaluation value P2B of occurrence of the collision of car B is as follows: P2B= 0.1x
2 = 0.2 The car call occurrence evaluation value P2G of car No. C is P2C = 1.0.

TA is PTA = PIA Xo, 8 + P2A Xo
, 2-1.04+0.14=1.18. Also, B
The forecast comprehensive evaluation value PTB of the unit is PTB±PIB x O

The series of allocation processing is completed. Each car control device (2A) of Car A displays the car to be serviced by lighting the hall lantern (42A), and the waiting customers wait in front of it.

図のステップＳ１に戻る。However, suppose that car A is delayed due to a car call, and car C arrives first. When a so-called "forecast failure" occurs, the process proceeds from step S5 to step S56, and step 551. of the detailed diagram shown in FIG. S52. In S54, the elements of the evaluation values are compared. In this case, the forecast car is car A and the first car is car C, so in step 551, the first-come, first-served predicted evaluation value of the forecast car is PIA = 1.30, and the first-come-first-served predicted evaluation value of the first car is PIC = 0.77. , “NO.
”. In step S54, the car call occurrence prediction evaluation value for the forecast is P2^-0.7, and the car call generation prediction evaluation value for the first arrival car is P2C=1. becomes O, rYE
Becomes S.J. In step 555, the value of α is multiplied by 0.9, so the value of α, which was 0.8 until now, is now 0.8 xo, 9
MO, 72, which means that the car call occurrence prediction evaluation value will be given more importance in the future. Once this step is completed, the third
Return to step S1 in the figure.

。In the above embodiment, the first-come-first-served expected evaluation value and the expected car call occurrence evaluation value were explained as elements of the expected comprehensive evaluation value, that is, the evaluation value for allocating elevators in consideration of forecast deviations, but the present invention is not limited to these. . For example, the maximum expected arrival time and the minimum expected arrival time may be determined by taking into account variations in expected arrival times, and this time or a combination of this time and other times may be used as an element. If we adopt the idea of ``221 Urunet'', which has been in the spotlight in recent years, we can learn coefficients by taking raw data such as car position, car direction, car call position, and hall call position as elements and taking their linear sum. I will continue to do so.

Since the weighting coefficients of the elements that create the values are varied, the probability of failure in the prediction of the elevator serving a hall call is reduced, and passengers waiting at the hall can wait for the elevator with peace of mind.
