Abstract
The invention relates to systems and methods for improving planning, scheduling, and supply chain management. Various embodiments of the invention provide systems and methods for managing inventory of different types of items in a supply chain. One aspect of the invention focuses on a method for managing inventory of similar items in a supply chain. The method includes determining a flow path for items in a supply chain, wherein the flow path comprises at least one operation. The method also includes receiving inventory data for items at each operation; storing the inventory data; determining a demand factor for the items; and determining a cost factor for the items. The method further includes based in part on the demand factor and the cost factor, determining an exchange curve for the items; and displaying a portion of the inventory data for the items and the exchange curve.

11. A method for managing lot sizes of similar items in a supply chain, wherein the supply chain comprises at least one station, the method comprising:
-
(a) determining an initial lot size for items at a first station;
(b) receiving routing data for items at each station;
(c) storing the routing data;
(d) based on the routing data, determining a cycle time for the items flowing from the first station through the supply chain;
(e) based on at least the cycle time for the items flowing from the first station through the supply chain, selecting a desired cycle time for the items; and
(g) based on at least the selected desired cycle time for the items, adjusting the initial lot size for the items at the first station.

-
(a) determining an initial lot size for a first type of item at a first station;
(b) determining an initial lot size for a second type of item at the first station;
(c) receiving routing data for each type of item as the items flow from the first station through the supply chain;
(d) storing the routing data;
(e) based on the routing data, determining a cycle time for each type of item flowing from the first station through the supply chain;
(f) based on at least the cycle time for the items flowing from the first station through the supply chain, selecting a desired cycle time for each type of item; and
(g) based on at least the desired cycle time for each type of item, adjusting the initial lot size for each type of item at the first station. - View Dependent Claims (13, 14, 15, 16, 17)
