A method, a medium, and a system for distributing a warehouse task from a warehouse management hub to a programmable logic controller comprise receiving at least one warehouse task at a warehouse management hub including attributes for physically transferring at least one product into a warehouse, out of the warehouse or within the warehouse, determining, by the warehouse management hub and based on the attributes of the warehouse task, one of a plurality of warehouse management devices for processing the warehouse task, sending, by the warehouse management hub, the warehouse task to the determined warehouse management device, identifying, by the determined warehouse management device and based on the attributes of the warehouse task, a first one of a plurality of programmable logic controllers, and sending, by the determined warehouse management device, a message including information for carrying out the warehouse task to the identified programmable logic controllers.

Distributing a warehouse task from a warehouse management hub to a programmable logic controller in a distributed warehouse system

Methods and system are disclosed that improve warehouse management operations. in one aspect, an enterprise application (e.g., warehouse management system) receives a message to process a request from a programmable logic controller. In response to a failure to process the request, status identifiers may be determined. The status identifiers may indicate errors that may have resulted in response to the failure to process the request. Based on the errors, the enterprise application may be configured with time intervals to re-process the request. After a lapse of the configured time interval, the enterprise application may be asynchronously triggered to automatically re-process the request.

Re-processing requests in automated warehouses

The present disclosure relates to a material handling method of performing by means of an automatic mechanical material handling equipment controlled by a control system at least a first and a second access task for accessing respectively at least a first and at least a second article stored in a material handling storage system, the first and second access tasks having been assigned a first and a second execution priority respectively. The method comprises a) controlling the automatic mechanical material handling equipment to perform the first access task having the highest priority; and in parallel to performing the first access task a1) evaluating data indicative of the material handling storage system for determining that a first intermediate task is to be performed, wherein the first intermediate task is required in order to perform by the automatic mechanical material handling equipment the second access task; and a2) assigning an execution priority to the first intermediate task higher than the second execution priority; b) controlling the automatic mechanical material handling equipment to perform at least the first intermediate task and the second access task according to the order of execution priorities.

Material handling method

A system and method for concurrency management in an environment, in which a common pool of objects is shared by multiple users. A virtual lock owner is created for a main thread of a processing task. The main thread spawns parallel threads to update the objects in the common pool with locks. The virtual lock owner is passed to each parallel thread. Each thread (including the main thread) is associated with a thread dependent lock indicator identified by the virtual lock owner. The lifetime of the thread dependent lock indicator is coupled with the lifetime of the associated thread. The virtual lock owner is also associated with a thread independent lock indicator that has a lifetime independent of the lifetime of the main thread. Thus, the parallel threads can perform object update with lock protection even if the main thread aborts.
