Plant-wide optimization including batch operations
Constraints are received on initial components and intermediate components. Information is received on the products to be produced including a quantity of each of the products to be produced and a specification that specifies how the intermediate components are to be combined to form each of the products. An optimization is performed that includes the continuous conversion of initial components into the intermediate components as well as subsequent production of the products, subject to the constraints on each of the initial components, the constraints on each of the intermediate components, and the quantity of each of the products to be produced.
COGNITIVE PRESS-FIT FORCE ANALYZER AND MONITORING SYSTEM
In an approach to creating a press-fit force analysis, one or more computer processors retrieve a force press-fit data from a press-fit machine based on a press cycle. One or more computer processors calculate a deformation force of the press cycle based on the press-fit data and storing the deformation force. One or more computer processors create a predictive control model based on the deformation force and determine if a corrective action is required based on at least one of a raw material quality data, machine setting data, a completed lot quality data or the predictive control model. One or more computer processors determine if a corrective action is required and alert a downstream process to take the corrective action. One or more computer processors schedule a material kitting.

Predictive control method for torque-rate control and vibration suppression
A method and system for robot motion control using a model predictive control (MPC) technique including torque rate control and suppression of end tooling oscillation. An MPC module includes a robot dynamics model which inherently reflects response nonlinearities associated with changes in robot configuration, and an optimization solver having an objective function with a torque rate term and inequality constraints defining bounds on both torque and torque rate. The torque rate control in the MPC module provides an effective means of controlling jerk in robot joints, while accurately modeling robot dynamics as the robot changes configuration during a motion program. End tooling oscillation dynamics may also be included in the MPC objective function and constraints in order to automatically control end tooling vibration in the calculations of the MPC module.
