Cooperative stock optimization for integrative supply chain management

A stock management data processing system configured for stock rebalancing, the system comprising:

• a host computing platform of one or more computers, each with memory and at least one processor, the host computing platform comprising a supply chain information sharing application operable to provide transparent and secure access to data in a knowledge graph from over a computer communications network from different actor information systems executing in respectively different servers for correspondingly different actors in the supply chain through an information sharing interface adapting messages internal to the actor information systems to the knowledge graph of the supply chain information sharing application, the knowledge graph organizing and integrating data according to an ontology and applying a reasoner to derive new knowledge,
• the host computing platform further comprising a first communicative coupling over the computer communications network to different remote computing systems, a first subset of the different remote computing systems corresponding to individual inventory holding clients and providing stock level information in the knowledge graph for different items in inventory at different geographic locations and tracked by respective ones of the remote computing systems, a second subset of the different remote computing systems each publishing transport capacity in the knowledge graph of corresponding transporter clients each able to transport items from one of the different geographic locations to another of the geographic locations;
• and,
• a stock rebalancer module coupled to the knowledge graph and comprising computer program instructions executing in the memory of the host computing platform and enabled to register the inventory holding clients each as individual publishers of inventory level data to the knowledge graph, and further register the transporter clients each as individual publishers of transport capacity to the stock rebalancer in terms of an amount of volumetric space available to accommodate transport of items within a geographically defined area, receive from one of the inventory holding clients in the knowledge graph, an indication of an overstock condition of a specified item and contemporaneously receive from another of the inventory holding clients, an indication of an understock condition of the specified item, and respond to the receiving of the indications of both the overstock and under stock conditions for the specified item by:
• identifying one of the transporter clients indicating excess capacity sufficient to bear transport of the specified item in a quantity indicated by the understock condition,
• messaging the one of the inventory holding clients, the another of the inventory holding clients and the one of the transporter clients indicating the overstock, the understock and the excess capacity condition,
• querying a table of override rules with an identity of the specified item, an identity of the one of the inventory holding clients publishing the overstock condition, an identity of the one of the inventory holding clients publishing the understock condition, an identity of the identified one of the transport clients and a cost of transportation by the identified one of the transport clients, and receiving in response an indication of whether or not the specified item is prohibited by an override rule referenced in the table to be transported from the one of the inventory holding clients publishing the overstock condition to the selected one of the one of the inventory holding clients indicating the understock condition, and,
• directing the identified one of the transport clients to transport the specified item in the indicated quantity from the one of the inventory holding clients indicating the overstock condition to the one of the inventory holding clients indicating the understock condition on condition that the override rules do not prohibit the specified item from being transported from the one of the inventory holding clients publishing the overstock condition to the selected one of the one of the inventory holding clients indicating the understock condition.

A computer program product for stock rebalancing, the computer program product including a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform a method including:

• executing a stock rebalancer in a host computing system and communicatively coupling the stock rebalancer to a supply chain information sharing system also executing in the host computing system, the supply chain information sharing system operable to provide transparent and secure access to data in a knowledge graph through an information sharing interface adapting messages to the knowledge graph, the knowledge graph organizing and integrating data according to an ontology and applying a reasoner to derive new knowledge;
• registering in the stock rebalancer separate inventory holding clients each as individual publishers of inventory level data to a stock rebalancer, and further registering separate transporter clients each as individual publishers of transport capacity to the stock rebalancer in terms of an amount of volumetric space available to accommodate transport of items within a geographically defined area;
• adapting messages received over a computer communications network from each of the inventory holding clients and the transporter clients to the knowledge graph through the information sharing interface of the supply chain information sharing system;
• receiving an indication from the knowledge graph in the stock rebalancer as placed therein from one of the inventory holding clients, an indication of an overstock condition of a specified item and contemporaneously receiving an indication from the knowledge graph in the stock rebalancer as placed therein from another of the inventory holding clients, an indication of an understock condition of the specified item;
• and,
• responsive to the receiving of the indications of both the overstock and under stock conditions for the specified item:
• identifying one of the transporter clients indicating excess capacity sufficient to bear transport of the specified item in a quantity indicated by the understock condition,
• messaging the one of the inventory holding clients, the another of the inventory holding clients and the one of the transporter clients indicating the overstock, the understock and the excess capacity condition,
• querying a table of override rules with an identity of the specified item, an identity of the one of the inventory holding clients publishing the overstock condition, an identity of the one of the inventory holding clients publishing the understock condition, an identity of the identified one of the transport clients and a cost of transportation by the identified one of the transport clients, and receiving in response an indication of whether or not the specified item is prohibited by an override rule referenced in the table to be transported from the one of the inventory holding clients publishing the overstock condition to the selected one of the one of the inventory holding clients indicating the understock condition, and,
• directing the identified one of the transport clients to transport the specified item in the indicated quantity from the one of the inventory clients indicating the overstock condition to the one of the inventory holding clients indicating the understock condition on condition that the override rules do not prohibit the specified item from being transported from the one of the inventory holding clients publishing the overstock condition to the selected one of the one of the inventory holding clients indicating the understock condition.
