Abstract

A method of managing a plurality of washrooms in a facility for servicing by service personnel and, more particularly, for establishing servicing operations which provide for service of at least selected of the dispensers before their consumable product supply falls below a pre-selected refill value.

First claim

We claim:

1. A system for managing a plurality of washrooms in a facility for servicing by service personnel comprising:
a server; and
a plurality of smart dispensers, each for dispensing a consumable product at different locations fixed within the facility, and with each smart dispenser having a maximum capacity for the consumable product,
wherein each smart dispenser has a system for monitoring a supply of the consumable product available in the smart dispenser and communicating data regarding the consumable product available in the smart dispenser to the server;
wherein the server establishes for each smart dispenser a predictive consumption profile representing the consumable product estimated to be available in each smart dispenser with time into the future,
wherein the server establishes for each smart dispenser a refill value for the consumable product available in each smart dispenser,
wherein the server establishes for each smart dispenser a refill time when the consumable product available in each smart dispenser is expected to reach the refill value as a function of the predictive consumption profile for that smart dispenser,
wherein the server establishes for each smart dispenser a service time required for service personnel to refill the consumable product in that smart dispenser,
wherein the server determines one or more pathways for service personnel to travel between each washroom within the facility and a travel time for each pathway,
wherein the server establishes a route for each service personnel by selecting successive pathways for each service personnel to travel along to service smart dispensers as a function which (a) minimizes the sum of the travel times of the pathways of the route and the service times for each smart dispenser serviced, (b) provides for service of each of the smart dispensers before the consumable product available in any smart dispenser is expected to reach the refill value;
wherein there are one or more offices within the facility where one or more service personnel are located when not servicing the smart dispensers,
wherein the server determines one or more pathways for service personnel to travel between each office and the washrooms within the facility and a travel time for each pathway, and
wherein the server establishes the route for each service personnel including both the pathways for service personnel to travel between each washroom within the facility and the pathways for service personnel to travel between each office and the washrooms within the facility by selecting successive of the pathways for each service personnel to travel along to service smart dispensers as a function which (a) minimizes the sum of the travel times of the pathways of the route and the service times for each smart dispenser serviced, and (b) provides for service of each of the smart dispensers before the consumable product available in any smart dispenser is expected to reach the refill value.

2. The system according to claim 1 , wherein the facility has one or more product storage spaces;
wherein the server determines one or more pathways for service personnel to travel between each product storage space and each washroom within the facility and a travel time for each pathway;
wherein each product storage space has a system for monitoring a supply of the consumable product available in the product storage space and communicating data regarding the consumable product available in the product storage space to the server;
wherein the server establishes the route for each service personnel including the pathways for service personnel to travel between each product storage space and each washroom within the facility, the pathways for service personnel to travel between each washroom within the facility, and the pathways for service personnel to travel between each office and the washrooms within the facility by selecting successive of the pathways for each service personnel to travel along to service the smart dispensers as a function which (a) minimizes the sum of the travel times of the pathways of the route and the service times for each smart dispenser serviced, and (b) provides for service of each of the smart dispensers before the consumable product available in any smart dispenser is expected to reach the refill value.

3. The system according to claim 1 , wherein the facility has one or more product storage spaces;
wherein the server determines one or more pathways for service personnel to travel between each product storage space, each office and each washroom within the facility and a travel time for each pathway;
wherein each product storage space has a system for monitoring a supply of the consumable product available in the product storage space and communicating data regarding the consumable product available in the product storage space to the server;
wherein the server establishes the route for each service personnel including the pathways for service personnel to travel between each product storage space, each office and each washroom within the facility, the pathways for service personnel to travel between each washroom within the facility, and the pathways for service personnel to travel between each office and the washrooms within the facility by selecting successive of the pathways for each service personnel to travel along to service the smart dispensers as a function which (a) minimizes the sum of the travel times of the pathways of the route and the service times for each smart dispenser serviced, and (b) provides for service of each of the smart dispensers before the consumable product available in any smart dispenser is expected to reach a nil value.

4. The system according to claim 1 , further comprising a location system for monitoring in real time a location of each service personnel within the facility.

5. The system according to claim 4 , wherein the server monitors the supply of the consumable product available in each smart dispenser in real time.

6. The system according to claim 5 , wherein the server modifies the route in real time having regard to the real time location of each service personnel within the facility and the consumable product available in each smart dispenser in real time.

7. The system according to claim 1 , wherein for each route, the server sets one of the one or more offices as a route finish location.

8. The system according to claim 1 , wherein for each route, the server sets one of the one or more offices as a route start location.

9. The system according to claim 1 , wherein the server establishes for each smart dispenser the predictive consumption profile based on a function of (a) historical monitoring of each smart dispenser and (b) predicted usage of each smart dispenser.

10. The system according to claim 1 , wherein the server establishes one or more servicing operations,
each servicing operation having one of the service personnel, a start time, a selected group of the smart dispensers, and the route for each service personnel;
wherein the server selects the service personnel, the start time, the selected group of the smart dispensers, and the route for each servicing operation as a service function which provides for service of each of the smart dispensers to replenish the consumable product in the smart dispensers before their respective refill time.

11. The system according to claim 10 , wherein the system selects the service personnel, the start time, the selected group of the smart dispensers, and the route for each servicing operation to provide for servicing of predetermined one or more key smart dispensers of the smart dispensers to extend the refill time for each key smart dispenser.
