Zukui Li, Auteur ; Ran Ding, Auteur ; Christodoulos A. Floudas, Auteur |Robust counterpart optimization techniques for linear optimization and mixed integer linear optimization problems are studied in this paper. Different uncertainty sets, including those studied in literature (Le., interval set; combined interval [...]

Zukui Li, Auteur ; Qiuhua Tang, Auteur ; Christodoulos A. Floudas, Auteur |Probabilislic guarantees on constraint satisfaction for robust counterpart optimization are studied in this paper. The robust counterpart optimization formulations studied are derived from box, ellipsoidal, polyhedrai, "interval+ellipsoidal", an[...]

Chrysanthos E. Gounaris, Auteur ; Ruth Misener, Auteur ; Christodoulos A. Floudas, Auteur |This work discusses alternative relaxation schemes for the pooling problem, a theoretically and practically interesting optimization problem. The problem nonconvexities appear in the form of bilinear terms and can be addressed with the relaxatio[...]

Global optimization of gas lifting operations : a comparative study of piecewise linear formulations
Ruth Misener, Auteur ; Chrysanthos E. Gounaris, Auteur ; Christodoulos A. Floudas, Auteur |Continuous gas lifting is the process of increasing oil well production by injecting compressed natural gas, called “lift gas”, into the production tubing of an oil well [ Presented at the SPE Gas Technology Symposium, Calgary, Alberta, Canada, [...]

Ruth Misener, Auteur ; Christodoulos A. Floudas, Auteur |The generalized pooling problem is a generic way of identifying a topology containing sources nodes, intermediate storage tanks, and sinks when monitoring specific stream qualities is imperative. One important application domain of the generaliz[...]

Peter M. Verderame, Auteur ; Christodoulos A. Floudas, Auteur |The operational planning and the medium-term scheduling of a multipurpose and multiproduct batch chemical plant are inter-related activities that involve the allocation of plant resources. Because of their disparate time scales, however, the eff[...]

Peter M. Verderame, Auteur ; Christodoulos A. Floudas, Auteur |Operational planning, medium-term scheduling, and short-term scheduling are closely related activities. Despite prior advances, the effective integration of planning and scheduling under demand and processing time uncertainty remains a challengi[...]

Peter M. Verderame, Auteur ; Christodoulos A. Floudas, Auteur |The operational planning of a multisite production and distribution network entails determining the daily production and shipment profiles for the supply chain under consideration. The generated profiles should provide a tight upper bound on the[...]

Munawar A. Shaik, Auteur ; Christodoulos A. Floudas, Auteur |Unit-specific event-based continuous time models have gained significant attention in the past decade for their advantages of requiring less number of event points, smaller problem size, and hence, a better computational performance. In the lite[...]

Jie Li, Auteur ; Peter M. Verderame, Auteur ; Christodoulos A. Floudas, Auteur |The operational planning problem typically determines both the plant’s aggregate and daily production targets to meet product demands over a long time horizon varying from one to three months. The daily production profile generated from the oper[...]

Peter M. Verderame, Auteur ; Christodoulos A. Floudas, Auteur |The operational planning of a large-scale industrial batch plant typically occurs over a time horizon of several months with the goal of providing daily production targets and raw material requirements for the plant in question. Due to the lengt[...]

Peter M. Verderame, Auteur ; Christodoulos A. Floudas, Auteur |A novel framework based on conditional value-at-risk theory has been applied to the problem of operational planning for large-scale industrial batch plants under demand due date and amount uncertainty. The nominal planning with production disagg[...]

Jie Li, Auteur ; Christodoulos A. Floudas, Auteur |In the past two decades, three types of continuous-time models have been developed for the short-term scheduling of multipurpose batch plants: sequence-based, slot-based, and event-based models. Both slot- and event-based models require an itera[...]

Richard C. Baliban, Auteur ; Josephine A. Elia, Auteur ; Christodoulos A. Floudas, Auteur |This paper, which is the first part of a series of papers, introduces a hybrid coal, biomass, and natural gas to liquids (CBGTL) process that can produce transportation fuels in ratios consistent with current U.S. transportation fuel demands. Us[...]

Josephine A. Elia, Auteur ; Richard C. Baliban, Auteur ; Christodoulos A. Floudas, Auteur |This paper, which is the second of a series of papers, presents an approach for the generation of a novel heat exchange and power recovery network (HEPN) for use with any large-scale process. A three-stage decomposition framework is introduced t[...]
