International Classification:

G05B 19/418
G06F 17/50
G06F 19/00
G06F 9/44

US Classification:

705 8, 700 97, 700108, 705 7, 705 9, 703 1

Abstract:

A dynamic planning method (DPM) generates a DPM project planning model. The DPM project planning model provides an activity pre-structured process model for activities of a DPM project plan. The DPM project planning model also provides a relationship pre-structured model for activity time precedence relationships of the DPM project plan. The DPM project planning model is dynamically adjusted to generate a DPM project plan, whereby reliability buffers are associated with one or more activities of the plan. Time precedence relationships are associated with the reliability buffers and with the activities. A variety of DPM simulation outputs are also generated. The DPM simulation outputs provide a comparison of the DPM project plan with conventional project plans generated by conventional project planning models.

Abstract:

A reliability buffering technique applies a reliability time buffer to a project planning model having activities. The reliability time buffer is placed before an associated downstream activity to provide a buffered downstream activity. The reliability buffer is provided having a time duration value and an activity time precedence relationship, including a lead or lag value, with at least one upstream activity. The time duration value and the activity time precedence relationship are generated so as to reduce the overall schedule delay resulting from possible time delays that occur in the one or more upstream activities and to increase the overall project schedule advance from possible schedule advances in the one or more upstream activities.

International Classification:

G06F 1130

US Classification:

3951851

Abstract:

A method of managing faults in a computer system including the steps of detecting an error, handling the error along a functional hierarchy and, further, handling a fault that caused the error in a management hierarchy which can be operated separately from the functional hierarchy.

International Classification:

G06Q 10/08
G06Q 50/28
G06N 20/00
B65G 1/137

Abstract:

A computer-based technology is provided to optimize a warehouse space, such as warehouse racks. The technology determines a storage duration of a pallet in a warehouse, and further determines an optimal storage location for the pallet in the warehouse. For example, the technology can determine how long an inbound pallet will stay in a warehouse, and locate an optimal area of the warehouse to store the pallet. Such an optimal pallet storage area is selected to reduce labor costs in transporting the pallet in, within, and out of the warehouse and further optimize the management of multiple pallets in the warehouse as a whole. In addition, the technology can consider the size of the pallet in determining the optimal storage location in the warehouse.

H04N 5/235
G06T 7/00

Abstract:

Systems and methods for profiling a pallet in a warehouse can include a turntable that rotates the pallet, conveyor belts that move the pallet, and a vertical profiling structure, having cameras mounted at different locations, in a stationary position proximate to a side of the turntable. A photo booth can also be used to provide uniform lighting. A computing system can instruct a conveyor belt to automatically route the pallet onto the turntable, instruct the cameras to capture image data of the pallet as it rotates on the turntable, receive the image data, and retrieve image-based models of the pallet that were trained using images of pallets having unique identifiers. The computing system can determine, based on applying the image-based models to the image data, whether the pallet's unique identifier is identifiable, and transmit, to a warehouse management system, a notification indicating whether the unique identifier is identifiable.
