| 1. A method for continuous replenishment planning of a consignment inventory, comprising:
providing a consignment storage including material from each vendor of a plurality of vendors;
setting, for a pre-determined time period, a target quantity of material for each vendor of the plurality of vendors wherein
the target quantity of material includes a first quantity of material to be stored in the consignment storage;
determining at least one of a high quantity value, a low quantity value, and a safe limit quantity value for each vendor of
the plurality of vendors, wherein the high quantity value, the low quantity value and the safe limit quantity value each include
a value associated with a quantity of material stored in the consignment storage;
selecting material to be dispatched from the consignment storage, from each vendor of the plurality of vendors, wherein the
selecting material includes calculating vendor priority, and wherein the calculating vendor priority includes:
calculating, for each vendor of the plurality of vendors, a target rate wherein the target rate equals a vendor target quantity
divided by a summation of all vendor target quantities;
calculating, for each vendor of the plurality of vendors, a consumption rate wherein the consumption rate equals a vendor
issued quantity from consignment-storage divided by a summation of all vendor issued quantities from consignment storage;
calculating, for each vendor of the plurality of vendors, an achieved rate whereby the achieved rate equals the consumption
rate minus the target rate; and
dispatching the selected material; and
automatically updating a vendor stock status record periodically, wherein the vendor stock status record provides an indication
of a current quantity of material stored in the consignment storage by each vendor of the plurality of vendors.
