ABSTRACT:
FIELD OF INVENTION
The present invention relates generally to article processing and delivery, and specifically to a computer-implemented method and system for optimally routing an article through a network of processing, delivery and routing stations, centrally tracking the location, controlling, and routing the article within the network either individually or as part of a group of articles.
BACKGROUND OF THE INVENTION
More so today than at any time in the past, businesses and consumers require more efficient, flexible, and economic methods for transportation and delivery of articles such as raw materials, manufactured goods, packages, parcels and parts. Today's retailers, wholesalers and manufacturers make use of advanced “supply-chain” models to maintain minimal inventories and “work in progress”, make maximum use of limited warehousing and storage capabilities, and in the process reduce costs while maintaining output capabilities sufficient to meet changing demand. In order to fully realize the benefits of these modern logistics and manufacturing models, businesses require systems which minimize transit times, allow for maximum control of goods (i.e., the ability to re-route and hold articles in transit) and permit up-to-the-minute tracking of articles. In addition, in order to minimize transportation and translocation costs, it is beneficial to have the ability to consolidate or de-consolidate groups of articles while in transit without loosing the ability to track and route articles individually. It is also important for businesses to have accurate information regarding estimated production, delivery and pick up times for articles, to be able to adjust such times to meet production requirements and to have “end to end” accountability of shipments in transit.
In a manufacturing setting, it is also necessary to maintain complete control over the tracking and routing of parts, assemblies, raw materials and other articles as they flow through a production process. Important characteristics of a routing and tracking system for use in a manufacturing situation include the ability to account for and divert parts and partial assemblies to locations in the manufacturing process where they are needed the most. Additionally, such a system must be able to accurately track Work-In-Process in order to actually project production throughput and timing for finished goods. In some industries such as pharmaceuticals, medical device manufacturing and aircraft parts manufacturing, such a system may play an integral role in tracking parts, assemblies or materials for regulatory related purposes. The manufacturing settings in question can be contained within a single building or be spread out geographically and any tracking a routing system used must be flexible enough to allow for either situation or a combination thereof.
In addition to their own manufacturing and supply chain needs, businesses require similar routing, tracking and control features for shipments whose ultimate recipient is a customer, whether it be a consumer or another business. In order to increase customer satisfaction and gain a competitive advantage, suppliers and retailers need to be able to provide the most accurate real time or near real time information regarding the location of an article, and the ability to re-route articles on an item or container basis.
From the consumer standpoint, modern retailing channels, such as mail-order catalogs, broadcast media, and the Internet, have increasingly relied on deliveries to allow purchasing of goods without the necessity of physically visiting traditional “brick and mortar” retail locations. In order to induce more consumers to utilize remote or virtual purchasing channels, it is imperative that delivery options be as convenient as possible and that they approach the options available to buyers in physical stores. It is important for consumers to be able to determine the exact location of an order and to be able to modify shipment routings to suit their convenience. It is also desirable to minimize delivery times by optimizing article delivery routes interactively and in real time based on timely updated fast-changing conditions such as traffic, available equipment, regional weather, etc.
Previous attempts have been made to provide methods for moving delivering, tracking or routing articles as described in U.S. Pat. No. 6,094,642 to Stephenson et al. (hereinafter “the '642 patent”); U.S. Pat. No. 5,043,908 to Manduley et al. (hereinafter “the '908 patent”); U.S. Pat. No. 6,047,264 to Fisher et al. (hereinafter “the '264 patent”); U.S. Pat. No. 4,630,216 to Tyler et al. (hereinafter “the '216 patent”); and U.S. Pat. No. 6,073,114 to Perkins, III et al. (hereinafter “the '114 patent”); all of which are incorporate herein by reference.
The '642 patent describes an integrated data collection and transmission system and method for collecting and transmitting data related to package delivery. The system and method utilize various components that are commonly connected via one or both of an infrared communications link and a microradio link. This system is limited in that it only provides tracking capabilities and no routing, re-routing, optimization or consolidation features.
The '908 patent describes a system for monitoring the delivery of mail pieces passing through multiple stages in a delivery network. The system relies on the application of a unique tracking ID to each piece of mail entering the network and associating with each such piece a set route and scheduled arrival times and dates at each stop along said route. The ID and corresponding schedule is stored in a central database maintained in a computer which is capable of querying local computers at each delivery stop. Upon arrival at each stop along its prescribed route, a mail piece's ID is recorded and an actual arrival time and date is entered into a local database maintained in said local computers. Periodically, the central computer queries all local stations for presence of a particular item. If an item fails to arrive at a delivery stop on schedule, or is delivered to an incorrect stop, an alarm is triggered which prompts an action within the system to locate a lost item and to expedite its delivery when, and if, it is located.
Because the system described by the '908 patent assigns a predetermined route to a mail piece upon entry into the delivery network, it can neither account for changing conditions nor change the route of a shipment on that basis. In addition, this system does not permit consolidation or de-consolidation of items in transit or tracking on an item-level basis for mail pieces grouped together for delivery to a common address. Finally, this system only allows for changes to the route of a mail piece when an alarm is triggered and does not permit changes to the final destination of the mail piece. Therefore this system does not provide complete control over delivery of items within it nor does it optimize the delivery route.
The '264 patent describes a method for automatically generating and transmitting e-mail messages to customers appraising them of tracking events related to their in-transit packages. The invention disclosed by the '264 patent is directed at merchants who ship goods to customers via common carriers who, in turn, track packages by referring to a unique tracking identification number. This invention allows customers to automatically receive updates, via e-mail, regarding the location of packages after they have been shipped by the merchant. Because it is merely a notification system the invention described in the '264 patent does not account for conditions affecting routing or delivery nor can it change, or in any way control, the route of a shipment on that, or any other, basis. In addition, the system does not permit consolidation or de-consolidation of items. Therefore this system also does not provide any control over delivery of items within it nor their delivery routes.
