METHOD AND EQUIPMENT FOR THE IMMEDIATE TARGET CALL ALLOCATION IN LIFT GROUPS BY REASON OF OPERATING COSTS AND OF VARIABLE BONUS AND PENALTY POINT FACTORS

摘要

In this method, target calls (R~~) are definitively allocated immediately to the individual lifts (N) for serving of the call by reason of higher rank and lower rank function requirements and these allocations are indicated immediately on the input storeys (E1 to E16). For this purpose, a weighted sum corresponding to higher rank function requirements is formed from partial operating costs (K1 to K n), this sum is modified into operating costs (K NR) in the sense of lower rank function requirements by means of variable bonus and penalty point factors (BF1...; MF1...) and a target call (R~~) is allocated to the lift (N) with the lowest operating costs (K NR). A target call allocation algorithm (ZZA) according to steps 1 to 6 (SR1 to SR6) with subordinate algorithms for the bonus and penalty point tracking (NFA) and the costs computation (KBA) serves for implementation of this method. The bonus and penalty point factors (BF1...; MF1...) are continuously made to follow the traffic volume or the cage load group by group or lift by lift with the tracking algorithm (NFA). The computation of the operating costs (K NR) takes place in the costs computation algorithm (KBA) according to a special costs formula, wherein the re-adjusted bonus and penalty point factors (BF1...; MF1...) act multiplicatively ona six-part partial costs sum. This allocation procedure improves above all the user friendliness and the quantitative aspects "waiting times" and "times to target". It utilises capacity reserves at low traffic for additional function requirements on the serving of calls.
