Elevator call allocation and routing system

An elevator system for allocating destination calls, said elevator system comprising:

• a group controller,
• a guiding portion that guides the passenger in the elevator system,
• at least one multi-deck elevator,
• at least one destination call device that accepts input of a destination floor at the beginning of a journey route, said input defining the starting point and final point of a passenger's journey route in the elevator system,
• an alternative route determination unit that forms possible route alternatives from the starting point to the final point of the passenger's journey route;
• a cost function generator that generates a cost function for the route alternatives, said function containing at least one travel time term;
• a travel time term value determination unit that determines the value of the at least one travel time term corresponding to each route alternative in the cost function;
• a cost calculator that calculates the total cost of each route alternative by using the generated cost function;
• a route allocator that allocates, for the passenger, the route alternative with the smallest calculated total cost;
• a guidance portion that guides the passenger to a waiting lobby and/or elevator according to the allocated route alternative;
• and
• a transfer route model unit that determines a travel time forecast for one or more transfer routes in the elevator system based on a criterion dependent on the state of the elevator system.

A computer readable medium having embodied thereon a program that, when executed in or with an elevator system, said elevator system including at least one multi-deck elevator, and a destination call device with which a passenger gives his/her destination floor at the beginning of the journey route, thereby defining the starting point and final point of the passenger's journey route in the elevator system, causes said elevator system to perform a method for allocating destination calls, the method comprising:

• generating possible route alternatives from the starting point to the final point of the passenger's journey route;
• determining a cost function for the route alternatives, said cost function containing at least one travel time term;
• determining the value of the at least one travel time term corresponding to each route alternative in the cost function;
• calculating the total cost of each route alternative by using the cost function;
• allocating, for the passenger, the route alternative having the lowest calculated total cost;
• guiding the passenger to a waiting lobby and/or elevator according to the route alternative allocated;
• and
• generating a transfer route model in which one or more travel time forecasts for one or more transfer routes in the elevator system are determined on the basis of a criterion dependent on a state of the elevator system.
