Bi-objective short-term scheduling in a rolling horizon framework: a priori approaches with alternative operational objectives
Lee, Do Yeon; Fukasawa, Ricardo; Ricardez-Sandoval, Luis (Elsevier, 2019-11)This study addresses short-term scheduling problems with throughput and make-span as conflicting objectives, focusing on a priori multi-objective methods. Two contributions are presented. The first contribution is to propose ... -
A density functional theory analysis on syngas adsorption on NiO (100) surface
Yuan, Yue; Dong, Xiuqin; Ricardez-Sandoval, Luis (Elsevier, 2019-12-31)Oxygen carrier (OC) design can effectively improve the performance of chemical looping combustion (CLC) and realize fossil fuel combustion at low energy-cost CO2 capture. This study describes the adsorption principles of ... -
A dynamic optimization framework for integration of design, control and scheduling of multi-product chemical processes under disturbance and uncertainty
Koller, Robert W.; Ricardez-Sandoval, Luis A. (Elsevier, 2017-11-02)A novel dynamic optimization framework is presented for integration of design, control, and scheduling for multi-product processes in the presence of disturbances and parameter uncertainty. This framework proposes an ... -
An integrated personnel allocation and machine scheduling problem for industrial size multipurpose plants
Santos, Fernando; Fukasawa, Ricardo; Ricardez-Sandoval, Luis (Elsevier, 2018-01-01)This paper describes the development and implementation of an optimization model to solve the integrated problem of personnel allocation and machine scheduling for industrial size multipurpose plants. Although each of these ... -
One-pot synthesis of porous silica-supported ultrafine Ni nanoparticles as efficient and stable catalyst for selective hydrogenation of benzophenone
Qiao, Xianliang; She, Tiantian; Zhang, Huiling; Wen, Xin; Niu, Libo; Ricardez-Sandoval, Luis; Li, Jingde; Bai, Guoyi (Elsevier, 2019-12-15)In this work, we report a silica-supported ultrafine Ni catalyst for the selective hydrogenation of benzophenone. This material was developed by a facile one-pot co-assembly syntheses strategy, using Ni(II) chelated alginate ... -
Recent advances on first-principles modeling for the design of materials in CO2 capture technologies
Yuan, Yue; You, Huabei; Ricardez-Sandoval, Luis (Elsevier, 2018-11-10)Novel technologies in consideration of industrial sustainability (IS) are in urgent need to satisfy the increasing demands from the society. IS realizes the production of materials and while maintaining environmental and ... -
Simultaneous Design and Control of Chemical Plants: A Robust Modelling Approach
Ricardez Sandoval, Luis Alberto (University of Waterloo, 2008-08-07)This research work presents a new methodology for the simultaneous design and control of chemical processes. One of the most computationally demanding tasks in the integration of process control and process design is the ...
