Abstract

A system and method are provided for maintenance of service areas within a facility by a plurality of attendants, wherein each service area has one or more product dispensers that require periodic refill. Via a sensor configured with each product dispenser and a control system in communication with the sensors, a product level or amount of product in each dispenser is determined. Based on information from the sensors, a respective refill time is computed for refilling each of the dispensers. Location of the attendants is tracked on a continuous or periodic basis. As a function of the computed refill times and location of the various attendants, one of the attendants is selected to service one or more of the product dispensers in a particular service area. An alert message is generated and transmitted to the selected attendant that gives the location of the particular service area within the facility. Determination of the selected attendant is made such that the selected attendant reaches the particular service area at or near the computed refill time of the one or more product dispensers in the particular service area facility.

First claim

What is claimed is:

1. A method for maintenance of a plurality of service areas within a facility by a plurality of attendants, wherein each service area has one or more consumable product dispensers that require periodic refill, the method comprising:
for each product dispenser, receiving, by a control system, information detecting a product level or amount condition of product in the product dispenser with a sensor configured with the product dispenser, the sensor in communication with the control system;
based on information from the sensors, computing, by the control system, a real time depletion rate, and, based upon the real time depletion rate and historical depletion data, calculating a respective refill time for refilling each of the product dispensers;
tracking, by the control system, location of the maintenance attendants within the facility;
as a function of the computed refill times, location of the attendants, and distance between the location of the attendants and one or more of the product dispensers in a particular service area containing an alerting product dispenser, selecting, by the control system, one of the attendants to service the alerting product dispenser and, optionally, one or more of the product dispensers in the particular service area containing the alerting product dispenser;
communicating and transmitting, by the control system, an alert message to the selected attendant that gives the location of the particular service area containing the alerting product dispenser within the facility and the computed refill time for the alerting product dispenser, and instructing the selected attendant to service the particular service area containing the alerting product dispenser on or before the computed refill time for the alerting product dispenser; and
wherein the selected attendant is determined such that the selected attendant reaches the particular service area containing the alerting product dispenser at or near the computed refill time of the alerting product dispenser in the particular service area;
wherein determination of the selected attendant is based on a predicted time for the selected attendant to reach the particular service area from an actual position of the selected attendant; and
wherein the attendants have established maintenance routes within the facility, and determination of the selected attendant is further based on the selected attendant reaching the particular service area at the predicted time while proceeding along their established maintenance route,
further comprising defining maintenance routes for the attendants within the facility for predefined time periods based on the computed refill times within the predefined time period.

2. The method as in claim 1 , wherein the product dispensers are any one or combination of towel dispenser, soap dispenser, or toilet tissue dispenser.

3. The method as in claim 2 , wherein the sensors are any one or combination of mechanical sensor, non-contact electrical sensor, weight sensor, or optical sensor.

4. The method as in claim 1 , wherein determination of the selected attendant is also based on an actual distance between the selected attendant and the particular service area.

5. The method as in claim 1 , wherein the particular service area is a service area assigned to the selected attendant's maintenance route.

6. The method as in claim 1 , wherein the particular service area is a service area assigned to a different attendant's maintenance route.

7. The method as in claim 1 , wherein the alert message also includes the refill time for the one or more product dispensers in the particular service area.

8. The method as in claim 1 , wherein multiple product dispensers are located in the particular service area, and when an alert message is generated for any one of the product dispensers in the particular service area, the method further comprises making a determination, by the control system, if one or more non-alerting product dispensers in the particular service area should be refilled by the selected attendant at the same time as the alerting product dispenser.

9. The method as in claim 8 , wherein the determination of whether the non-alerting product dispensers should be refilled is based on the computed refill time for the non-alerting product dispensers and location of other attendants in the facility.

10. The method as in claim 1 , wherein the alert message is transmitted to the selected attendant when the selected attendant comes within a defined distance from the particular service area.

11. The method as in claim 10 , wherein the selected attendant is determined to be a first one of the service area attendants that comes within the defined distance from the particular service area.

12. The method as in claim 1 , further comprising generating and storing, by the control system, a profile for each of the attendants, the profile including characteristics indicative of the individual attendant's speed and ability to refill the product dispensers at the service areas within the facility, and wherein the defining maintenance routes for the attendants include consideration of the attendant profiles.

13. The method as in claim 1 , further comprising generating and storing, by the control system, a profile for each of the attendants, the profile including characteristics indicative of the individual attendant's speed and ability to refill the product dispensers at the service areas within the facility, and wherein determination of the selected attendant includes consideration of the attendant profiles in addition to attendant location.

14. The method as in claim 13 , further comprising:
monitoring, by the control system, and updating the attendant profiles; and
determining, by the control system, the selected attendant based on a characteristic in a particular attendant's profile desired to be modified over time by repetitive product refill alert messages.

15. The method as in claim 14 , wherein the repetitive product refill alert messages are for increasingly more difficult product refill tasks in terms of any one or combination of distance to product dispenser, volume or amount of refill product needed, speed required to complete refill procedure within a defined time from alert message, relative time in the attendant's work shift, or frequency of refill alert messages.
