Equipment maintenance and automated inventory management using predictive modeling

A computer system for performing automated inventory management, the computer system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising instructions to:
• determine a service level, using a predictive model, for a count of inventory units for one or more sites of a plurality of sites, wherein the predictive model is provided with a reorder point and reorder quantity as input, wherein the predictive model further uses as input a mean daily demand for each site of the plurality of sites, an average issue size at each site of the plurality of sites, a mean supplier lead time for shipments of the inventory units, a price per inventory unit, and a central-to-remote site transfer time, and wherein the count of inventory units for the one or more sites is determined based on a notification that an autonomous robotic device at a particular site has performed an action that consumes one or more inventory units;
• in response to determining that the service level does not satisfy a threshold value, adjust the reorder point;
• determine that the adjusted reorder point yields a corresponding service level, wherein the input to the predictive model is used to determine that, according to the predictive model, the corresponding service level provided by the adjusted reorder point satisfies the threshold value;
• automatically transmit instructions, using a network interface, to cause a reorder of inventory units in response to determining that a count of inventory units is below the adjusted reorder point;
• and
• control the autonomous robotic device, by transmitting instructions using the network interface to the autonomous robotic device, to automatically maintain equipment at a site of the plurality of sites using the inventory units, wherein the autonomous robotic device automatically maintaining the equipment causes one or more inventory units to be consumed by removing at least one consumed inventory unit from the equipment and inserting at least one new inventory unit into the equipment.

A computer program product for performing automated inventory management, the computer program product comprising one or more computer readable storage media collectively having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• determine a service level, using a predictive model, for a count of inventory units for one or more sites of a plurality of sites, wherein the predictive model is provided with a reorder point and reorder quantity as input, wherein the predictive model further uses as input a mean daily demand for each site of the plurality of sites, an average issue size at each site of the plurality of sites, a mean supplier lead time for shipments of the inventory units, a price per inventory unit, and a central-to-remote site transfer time, and wherein the count of inventory units for the one or more sites is determined based on a notification that an autonomous robotic device at a particular site has performed an action that consumes one or more inventory units;
• in response to determining that the service level does not satisfy a threshold value, adjust the reorder point;
• determine that the adjusted reorder point yields a corresponding service level, wherein the input to the predictive model is used to determine that, according to the predictive model, the corresponding service level provided by the adjusted reorder point satisfies the threshold value;
• automatically transmit instructions, using a network interface, to cause a reorder of inventory units in response to determining that a count of inventory units is below the adjusted reorder point;
• and
• control the autonomous robotic device, by transmitting instructions using the network interface to the autonomous robotic device, to automatically maintain equipment at a site of the plurality of sites using the inventory units, wherein the autonomous robotic device automatically maintaining the equipment causes one or more inventory units to be consumed by removing at least one consumed inventory unit from the equipment and inserting at least one new inventory unit into the equipment.
