The present invention relates generally to the field of efficient movement, and more particularly to determining an optimal path for an elevator.
An elevator is a type of transportation that moves people or goods between floors, or levels, of a building or other structure. Elevators are generally powered by electrical motors that either drive traction cables or counterweight systems like a hoist or pump hydraulic fluid to raise a cylindrical piston (e.g., a jack). Because of wheelchair access laws, elevators are usually a requirement in new multistory buildings, especially where wheelchair ramps would be impractical.
Aspects of an embodiment of the present invention disclose a method, computer program product, and computing system for determining an optimal path for an elevator. A processor receives information, wherein the information includes social media data associated with a user and calendar entries associated with the user, indicating one or more locations within a building. A processor analyzes the received information. A processor determines a location to send an elevator within the building to minimize movement of the elevator, based on the analyzed information. A processor causes the elevator to move to the location.
Embodiments of the present invention recognize that, in modern large-scale structures, efficient use of elevators is critical to the movement of people within the structure. This has to do with both “busy” parts of the day where many people are attempting to change location, as well as issues with the use of space and the cost of installation of additional elevators. Many large-scale structures have moved to a system of using both express elevators and local elevators to reduce the number of floors at which each elevator needs to stop.
Additionally, there have been many attempts at automating the selection of an elevator car based on a particular floor of choice in an attempt to enhance the efficiency of the elevator car, as opposed to sending the closest elevator car when called without any idea of the floor the end user wishes to travel.
While the aforementioned improvements have enhanced the efficiency of the elevator to a certain degree, embodiments of the present invention recognize the improvements are not capable to truly extract the efficiencies that are capable with using modern analytics, machine learning, facial recognition, and sensor networks. Increasing the efficiency of elevators reduces the amount of space within a building that must be dedicated to elevators, as well as increasing user satisfaction with reduced wait times and quicker movement within the structure.
Embodiments of the present invention describe an approach for utilizing key information gathered about personnel (e.g., building staff) within a building to help allocate elevator resources. By gathering data via the infrastructure already present within a building (e.g., cameras, facial recognition, badge reads, employee calendar information, etc.), embodiments of the present invention allow building administrators, and businesses in general, to determine the optimal location and route for an elevator at any given time. In doing so, embodiments of the present invention may alert key personnel as to where the elevator should be. Additionally, embodiments of the present invention may automate the location of the elevator within the building. The determinations allow personnel within a business to approach an elevator and, in most cases, have the elevator awaiting, assuming the elevator is not already in use. In the event of multiple pickups across multiple locations, embodiments of the present invention allow for multipoint pickup based upon the high levels of efficiency. The added level of efficiency allows for not only faster response times for personnel pickup, but a significant reduction in the requisite power needed/used. Embodiments of the present invention determine an optimal path for one or more elevators.
Embodiments of the present invention will now be described in detail with reference to the Figures.

Herein, an embodiment of the present invention focuses on an elevator that moves vertically. Other embodiments may include other types of transportation for people and goods that may serve a similar purpose as an elevator. Additionally, in some embodiments, an elevator may, at some point, move in other directions, besides vertically.
In step 210, elevator efficiency program 110 receives information. The information received allows elevator efficiency program 110 to run an elevator more efficiently. In one embodiment, elevator efficiency program 110 receives calendar entries from any system that a business may use to document calendar entries that involve a room allocation (e.g., a room reserved for a meeting) that include a date and time, while also taking into account the people who are not registered as traveling within the calendar system. Additional calendar entries may involve large numbers of people being away from a building at a particular time. Elevator efficiency program 110 may store the received calendar entries to database 120 for future use.
In some embodiments, elevator efficiency program 110 receives information that includes public and/or private social media entries from social media server 40 that indicate the movement of people within a building, or create an inference about possible movement of people within the building. For example, three people within a building tweet one another to meet on the dining floor. In reference to obtaining private information, elevator efficiency program 110 receives permissions (not shown) to access private information. For example, a person may have the option to opt-out or opt-in with regard to providing access to his or her personal and/or private information (e.g., private social media entries). Elevator efficiency program 110 may store the received calendar entries to database 120 for future use.

Other information received from sensor 80 may include data from movement within a building and between floors as measured by way of badge access credentials, facial recognition, and/or any other methods of counting individuals moving throughout the building with an emphasis on the time of day and day of the week and floor movement patterns. Sensor 80 may include weight sensors within the elevator cars to determine available remaining weight capacity, as well as optical and facial recognition sensors to determine remaining volumetric and two-dimensional capacity within an elevator car. Elevator efficiency program 110 may store information received from sensor 80 to database 120 for future use.
In some embodiments, elevator efficiency program 110 receives courier tracking data from courier server 70 for parcel delivery, including expected/predicted delivery times and destinations within a building. Elevator efficiency program 110 may store the received tracking data to database 120 for future use.
In other embodiments, elevator efficiency program 110 receives geographically relevant weather data from weather server 60 to help predict the number of people within a building. For example, during extreme weather, i.e., very hot or very cold and rainy weather, there may be an expectation that people will stay in the building for longer periods of time once they enter. During a day where the weather conditions are pleasurable, there is an expectation that people are in and out of the building at a higher frequency. The people may be in and out of the building for lunch, meetings, gathering with friends, or a number of other reasons that people may gather outside. Additionally, on days with heavy snow, there is an expectation that people may not even be able to leave the house, and thus, there may be an expectation that there will be fewer people in the building. Elevator efficiency program 110 may store the received weather data to database 120 for future use.
In some embodiments, elevator efficiency program 110 receives mass transit system schedules within a geographical region from mass transit system server 50 to provide information on possible delays and arrival times of building occupants. Elevator efficiency program 110 may store the received mass transit data to database 120 for future use.
In other embodiments, elevator efficiency program 110 receives historical elevator usage data. The historical elevator usage may come from a number of places, including, but not limited to: any of the above-mentioned servers, reports created by a building administrator, and/or any other method that may be able to provide elevator efficiency program 110 with relevant data to assist in making the elevators within a building run more efficiently. Elevator efficiency program 110 may store the received historical usage data to database 120 for future use.
In step 220, elevator efficiency program 110 analyzes the information. In one embodiment, elevator efficiency program 110 applies analytics to take into account total expected elevator traffic for each accessible floor in a building throughout the day. In some embodiments, elevator efficiency program 110 applies analytics to the calendar and social media information to predict the movement of people and groups of people within a building. In other embodiments, elevator efficiency program 110 applies analytics to current occupancy data obtained from badge/closed-circuit television (CCTV) camera/facial recognition sources to determine occupancy ratio and predict elevator usage. In some embodiments, elevator efficiency program 110 applies analytics to predict elevator car utilization based on past trends of similar usage within a building. In other embodiments, elevator efficiency program 110 applies analytics to courier tracking information to determine time of courier arrival and internal building destination to predict elevator usage. Weather forecast information can be used to assist with predictive occupancy and time of an arrival to a building and used to model expected elevator usage.
In step 230, elevator efficiency program 110 determines an optimal elevator path. Throughout the day, in one embodiment, elevator efficiency program 110 determines where to stage elevator cars. In some embodiments, elevator efficiency program 110 determines optimal paths, on an as need basis, to increase the efficiency of personnel flow throughout a building. In other embodiments, as an added benefit, when elevator efficiency program 110 determines an optimal elevator path, the reduced elevator car movements will result in greater electrical energy savings.
In step 240, elevator efficiency program 110 causes the elevator to move. In one embodiment, elevator efficiency program 110 causes the elevator to move by sending instructions to the elevator based on the determined optimal elevator path or elevator location. In other embodiments, elevator efficiency program 110 sends the instructions to an administrator to allow the administrator to move the elevator as the administrator sees fit.
