Description

This invention relates to a building planning support system and a building planning support method. When planning the installation of elevators and other lifting equipment in a building, the number of users on each floor is estimated in advance. The number and size of elevators to be installed are then determined based on a simulation of the necessary transport capacity for that estimated number of users. Patent Document 1 describes a technique for calculating mobility demand data by associating the number of people in a building, the number of people, and the layout data. This technique involves performing simulations based on the calculated mobility demand data to determine pedestrian congestion and elevator car positions, and then using this data to plan elevator installation.

A building planning support system according to one embodiment of the present invention will be described below with reference to the attached drawings. [Overview of simulation using building planning support system] Figure 1 shows an overview of the simulation performed by the building planning support system 100 in this embodiment. As shown in Figure 1, the building planning support system 100 simulates whether movement between floors within the building 10 will be carried out appropriately, based on the expected number of people on each floor of the building 10 where the elevator EV1 is installed. Here, the users of elevator EV1 within building 10 include not only general users P1-P5 who are pedestrians, but also autonomously mobile robots R1-R4. The elevator car of EV1 can accommodate both users P1-P5 and autonomously mobile robots R1-R4. In addition, users P1-P5 include a wheelchair user (user P1 in Figure 1). In the following explanation, users will also be referred to as human agents, and mobile entities such as autonomously mobile robots will also be referred to as heterogeneous agents. The building planning support system 100 simulates elevator usage based on the number of elevator users P1 to P5 expected on each floor during a certain time period and the number of autonomously mobile robots R1 to R4. In the building planning support system 100, the output unit 140 outputs passenger simulation results, which are simulation results for users, and robot simulation results, which are simulation results for autonomous mobile robots. The output unit 140 also outputs elevator simulation results, which determine whether the number of elevator cars and the size of the elevator cars to be installed in the building 10 are appropriate. The following describes the details of the building planning support system 100 that performs such simulations.

The building planning support system 100 is composed of a computer device which is an information processing device, and includes a simulation unit 110, a storage unit 120, an input unit 130, and an output unit 140. The simulation unit 110 includes a CPU (Central Processing Unit) 111, which is a control unit that controls calculations for the simulation; a work memory 112 that executes calculation processing under the control of the CPU 111; and a program 113 that is executed by the CPU 111. The program 113 is stored in a storage medium such as ROM (Read Only Memory). The memory unit 120 consists of a large-capacity storage device such as an HDD (hard disk drive) or SSD (solid state drive), and stores the information necessary for the simulation. For example, the memory unit 120 stores elevator specification information 121, heterogeneous agent specification information 122, traffic demand information 123, and building specification information 124. Details of this information will be described later. The input unit 130 consists of a receiving unit that receives information and an input device that accepts operations from the oper
