{"title": ["", "Parallelising Mixed-Integer Optimisation: Energy Efficiency Applications"], "description": ["", "\nMathematical models for optimal decisions often require both nonlinear and discrete components. These mixed-integer nonlinear programs (MINLP) form an important class of optimisation problems of pressing societal need. For example, MINLP is necessary for optimising the energy use of large industrial plants, for integrating renewable sources into energy networks, for biological and biomedical design, and for countless other applications. The first MINLP algorithms and software were designed by application engineers. While these efforts initially proved very useful, scientists, engineers, and practitioners have realised that a transformational shift in technology will be required for MINLP to achieve its full potential.\n\nAs an example of the importance of MINLP, consider that many industrial processes involve heating and cooling liquids. With the present day focus on reducing CO2 emissions, e.g. the UK Climate Change Act 2008, reusing excess process heat becomes ever more important and a major challenge is increasing industrial plant efficiency via heat integration. Heat exchanger network (HEN) synthesis is most naturally formulated as a mixed-integer nonlinear optimisation problem (MINLP). Using an optimisation framework can result in tremendous energy and cost savings. In 2009, the South Korean refining company S-Oil estimated £28M annual savings at a single plant using a commercial optimisation package, AspenTech Energy Analyzer. But these are not the only gains available. Heat exchanger network synthesis is a nonconvex nonlinear optimisation problem with many local optima; we estimate additional possible savings on the order of 10% via developing better optimisation algorithms.\n\nDeterministic global optimisation of mixed integer nonlinear programs (MINLP) may effectively design energy efficient networks, but current MINLP technology for this problem class is limited by nonconvex nonlinear heat transfer functions and the many isomorphic possibilities of routing streams to heat exchangers. Parallelisation is attractive, but the naïve design of current parallelisation strategies is also inappropriate because effective tree exploration requires extensive inter-node communication. This proposal aims to develop novel internode communication strategies for MINLP branch-and-cut algorithms with a target of effectively addressing industrially-relevant energy efficiency optimisation problems.\n\nThis proposal is highly relevant to the 680k people working in the UK energy sector. This proposal falls under the EPSRC Engineering and Manufacturing the Future themes; MINLP is highly relevant to industrial design problems. The two related sub-themes are Sustainable Industrial Systems with a related research area of Energy Efficiency (EPSRC Research Action: Grow) and also Manufacturing Informatics with a related research area of Mathematical Aspects of Operational Research (EPSRC Research Action: Maintain). This proposal is also tightly linked to the EPSRC Working Together priority; the team includes the PI, the PDRA, a mathematician, a software company, and a consortium of process engineers. Since moving to the UK in 2012, the PI has attracted international attention for her MINLP contributions as evidenced by her 2 paper awards in 2013 and 2014; this EPSRC First Grant will establish her as researcher with a reliable track record of linking optimisation theory and practice.\n\n"], "extra_text": ["", "\n\nPotential Impact:\nDissemination and Exploitation\n\nThis grant has two project partners: GAMS Software GmbH and the Centre for Process Systems Engineering.\n\nGAMS Software GmbH (gams.com) develops algebraic modelling software for optimisation problems; their product consists of a language compiler with many integrated state-of-the-art optimisation solvers. Ruth collaborated with GAMS to release both GloMIQO and ANTIGONE; the GAMS software engineers have 25 years experience working with optimisation practitioners and they understand how users interact with mathematical algorithms.\n\nImpact Activities for this First Grant: As detailed in their letter of support, GAMS will work with us (primarily remotely) to translate the outputs of this grant into publicly available software. We will also meet for a concentrated half-day at one of the major conferences to make sure that the integration is smooth.\n\nThe Centre for Process Systems Engineering (CPSE) is a consortium with research interests spanning process modelling, design, operation and control, and numerical optimisation methods. This project partner will help translate the work in the First Grant into com-on practise by giving us the opportunity to communicate our work with the relevant industrial contacts. CPSE will also provide £500 in extra funding to complement the grant.\n\nPublic Outreach\n\nThe PI has already organised 2 successful booths at Imperial Festival; both were in conjunction with her Royal Academy of Engineering Research Fellowship. For First Grant, the PI and the PDRA will organise a booth centred around energy efficiency and highlight the work in this grant. A demo-version of software to optimally design a bioreactor was popular at the 2015 Imperial Festival:\n\nhttps://twitter.com/RuthMisener/status/597120123032469505;\n\nwe will similarly design an iPad or iPhone app demonstrating optimal energy efficiency.\n\n\n"], "status": ["", "Closed"]}
