Linear model predictive control is extended to both control and optimize a product grade schedule. The proposed methods are time-scaling of the linear dynamics based on throughput rates and grade-based objectives for product scheduling based on a mat

Highly accurate model predictions contribute to the performance and stability of model predictive control. However, high fidelity models are difficult to implement in real time control due to the large and often nonconvex optimization problem that mu

A novel formulation for combined scheduling and control of multi-product, continuous chemical processes is introduced in which nonlinear model predictive control (NMPC) and noncyclic continuous-time scheduling are efficiently combined. A decompositio

Thrombocytopenia and absent radii (TAR) syndrome is a congenital defect with osseous abnormalities and thrombocytopenia. It is inherited as an autosomal recessive trait, but the mechanism of thrombocytopenia in this disorder is not clear. We have had
