Abstract

A computer system for automatically ordering consumables for a printer or a similar machine where the inventory is monitored by comparing the amount of material delivered, for example, by scanning the incoming cartons, against the amount used, for example, by the machine automatically sending to the computer counts of the various units consumed. The computer is equipped with a set of rules for automatically reordering new supplies. In an alternative case, the rules would request a concession, in terms of price or some other parameter such as quantity, from one or more vendors before ordering.

Claims

1. A method for using an automatic system for tracking and ordering units comprising the:

A. a method of tracking an inventory of a current number of units comprising the steps of;

(1) adding a first number of units received from a vendor to the current number of units, and

(2) in response to a signal, subtracting a second number from the current number, and

B. the method of ordering additional units when the current number is at or below a predetermined threshold comprising the steps of;

(1) assembling a list of parameters for one or more quantities of units for one or more vendors, the parameters being price, quality, delivery schedule or quantity,

(2) using a set of rules programmed into an expert system with fuzzy rules for determining a selection based on information given by vendors without user intervention on an ordering site, and

(3) ordering the selection, and

C. the method wherein cryptographic methods of digital signature techniques are used to provide;

(1) the vendor with proof of order from an ordering computer, and

(2) receiving proof of receipt of the order from the vendor, and

D. the method wherein automatic electronic payment for goods ordered upon receipt of goods, and

E. the method wherein newer upgrades or products are advertised by the vendor using cryptographic means to;

(1) filter unsolicited messages from known vendors, and

(2) filter unwanted message from unknown vendors.

2. The system of claim 1 wherein each vendor is allowed to change a parameter in the list.

3. The system of claim 1 wherein the unit is a consumable.

4. The system of claim 1 wherein the automatic system, ordering computer and vendor communicate by a network.

5. The system of claim 4 wherein the ordering computer could include a cluster of ordering computers.

6. The system of claim 1 wherein the vendor receives proof of the order from the ordering computer and the ordering computer receives proof of the receipt of the order from the vendor.

7. The system of claim 1 wherein electronic filtering is used to allow only a change in a parameter from a selected vendor by having a message conform to a predetermined format.

8. An automatic system for tracking and ordering units comprising the steps of:

A. a method of tracking an inventory of a current number of units comprising the steps of;

(1) adding a first number of units received from a vendor to the current number of units, and

(2) in response to a signal, subtracting a second number from the current number, and

B. the method of ordering additional units when the current number is at or below a predetermined threshold comprising the steps of;

(1) assembling a list of parameters for one or more quantities of units for one or more vendors, the parameters being price, quality, delivery schedule or quantity,

(2) using a set of rules programmed into an expert system with fuzzy rules for determining a selection based on information given by vendors without user intervention on an ordering site, and

(3) ordering the selection, and

C. the method wherein cryptographic methods of digital signature techniques are used to provide;

(1) the vendor with proof of order from an ordering computer, and

(2) receiving proof of receipt of the order from the vendor, and

D. the method wherein automatic electronic payment for goods ordered upon receipt of goods.
