Method for immediate allocation of landing calls

Method for allocating calls entered via the landing call devices of elevators belonging to an elevator group using a genetic allocation procedure, characterized in that

• the service routes for the elevator cars are established via a search performed by the genetic allocation procedure, which decides which elevator is to serve which landing call,
• a call fixation control unit takes care of the reservation and release of landing calls and the control of signaling, the service routes thus established for the elevator cars are input into the call fixation control unit, which registers each landing call as being reserved for the elevator car suggested for it,
• in the case of a reserved landing call, the call fixation control unit determines an elevator car which is allowed to serve the call,
• in the case of a free landing call, all elevator cars can potentially be used to serve the call,
• in the case of a reserved landing call, only the assigned elevator car is ready to serve the call,
• the call fixation control unit decides which landing call is free and which is reserved,
• the call fixation control unit reserves the landing call for the elevator car to whose service route it was allocated by a landing call allocation unit during a first round of allocation,
• the call fixation control unit limits the alternative elevator cars of the gene corresponding to the call in the genetic allocation unit to one alternative, which is the elevator car previously allocated for the landing call.
