Abstract

The system and method include a fleet of vehicles to provide material to a plurality of tanks at various customer locations. An inventory indicator associated with each of the tanks provides a quantity signal to the central station indicating the quantity and temperature of each of the tanks. A processor at the central station monitors the quantity signals of each of the tanks to determine past usage rates of the contents of each of the tanks. The processor projects future tank quantities based on the past usage pattern and determines possible routes for each of the vehicles to each of the tanks. The processor optimizes the routes, delivery amounts, and delivery schedule to minimize total delivered cost for the products based on the projected future tank levels and the possible routes to dispatch each of the vehicles.

Claims

1. A system for using a fleet of vehicles to provide material to a plurality of tanks at various customer locations comprising:

a central station;

an inventory indicator associated with each of the tanks and providing a quantity signal to the central station indicating the quantity in each of the tanks; and

a processor at the central station for;

collecting and storing information from the inventory indicators;

monitoring the quantity signals of each of the tanks to determine past usage rates of the contents of each of the tanks;

projecting future tank quantities of each of the tanks based on the determined past usage rates;

determining possible delivery routes for each of the vehicles to each of the tanks;

optimizing the delivery routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost;

optimizing the delivery amounts for the routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost;

optimizing the delivery schedule for the routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost; and

dispatching each of the vehicles in accordance with the its optimized route and delivery schedule.

2. The system of claim 1 wherein each tank has a capacity and wherein the processor assigns a maximum order level for each tank which maximum order level is less than the capacity of the tank and wherein the processor optimizes the routes, delivery amounts and delivery schedule for a particular tank based on a delivery that would not be made unless the tank level is below maximum order level of the particular tank and the tank level is above the minimum inventory level.

3. The system of claim 2 wherein each tank has a heel level and wherein the processor assigns a minimum inventory level for each tank which minimum inventory level is greater than the heel level of the tank and wherein the processor optimizes the routes, delivery amounts and delivery schedule for a particular tank based on a delivery schedule that prevents the tank level from being less than the heel level of the particular tank.

4. The system of claim 1 wherein the processor generates discretionary orders and mandatory orders and wherein the processor optimizes the routes, delivery amounts and delivery schedule for a particular tank based on a delivery schedule that takes into account both discretionary orders and mandatory orders.

5. The system of claim 1 wherein the processor minimizes delivered cost based on fixed resources of drivers and equipment while maintaining all tanks with a minimum inventory.

6. The system of claim 1 further comprising a satellite link including a transponder on each of the vehicles communicating with the central station, said satellite link monitoring the position of the dispatched vehicles, indicating to the vehicles instructions from the central station and indicating to the central station the position of the dispatched vehicles.

7. The system of claim 6 wherein each of the dispatched vehicles indicates to the central station via the satellite link the amount of material delivered to a particular tank at a particular customer location and wherein the processor initiates the generation of billing information provided to each customer based on the amount of material delivered to a particular tank as indicated to the central station.

8. The system of claim 1 including an inventory memory storing level data indicating the level of material in each of the tanks, a past usage memory storing past usage data indicating the past usage rates of the material in each of the tanks, a future usage memory storing future usage data indicating information for projecting future usage of the material in each of the tanks, and a truck route memory storing routing data indicating the routes to be taken by the vehicles for supplying materials to each of the tanks.

9. The system of claim 8 including projection instructions projecting future levels of the tanks based on the level data, the past usage data and the future usage data, and including optimizing algorithms selecting the optimum routing data based on the projected future levels.

10. The system of claim 9 including billing instructions executed by the processor for generating invoicing and usage reports for each particular tank corresponding to past usage and delivery of materials to each particular tank.

11. The system of claim 1 wherein the processor assigns a consumption class to each particular tank based on past usage of the material in each particular tank and wherein the processor projects future tank levels based on the consumption class.

12. The system of claim 1 further comprising a meter on each vehicle for measuring an amount of material delivered to each particular tank, said meter having a transmitter for transmitting to the central station the amount of material delivered at each particular tank.

13. The system of claim 1 further comprising a temperature sensor at each tank for indicating a temperature corresponding to the temperature of the material in the tank and a link interconnecting the sensor and the central station and providing the indicated temperature to the central station.

14. A system for providing material to a plurality of tanks at various customer locations comprising:

a fleet of vehicles to provide materials to the plurality of tanks;

a central station;

an inventory indicator associated with each of the tanks and providing a quantity signal to the central station indicating the quantity in each of the tanks; and

a processor at the central station for;

collecting and storing information from the inventory indicators;

monitoring the quantity signals of each of the tanks to determine past usage rates of the contents of each of the tanks;

projecting future tank quantities of each of the tanks based on the determined past usage rates;

determining possible delivery routes for each of the vehicles to each of the tanks;

optimizing the delivery routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost;

optimizing the delivery amounts for the routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost;

optimizing the delivery schedule for the routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost; and

dispatching each of the vehicles in accordance with the its optimized route and delivery schedule.

15. A method for using a fleet of vehicles to provide material to a plurality of tanks at various customer locations comprising the steps of:

collecting from an inventory indicator associated with each of the tanks a quantity signal indicating the quantity in each of the tanks;

storing information from the inventory indicators;

monitoring the quantity signals of each of the tanks to determine past usage rates of the contents of each of the tanks;

projecting future tank quantities of each of the tanks based on the determined past usage rates;

determining possible delivery routes for each of the vehicles to each of the tanks;

optimizing the delivery routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost;

optimizing the delivery amounts for the routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost;

optimizing the delivery schedule for the routes for each of the vehicles based on the projected future tank quantities and based on the possible routes to minimize delivered cost; and

dispatching each of the vehicles in accordance with the its optimized route and delivery schedule.
