“…In the CTG case, the scope is limited to the factory gate and is commonly adopted by multiple consumers companies. Recent examples are Ruiz-Femenia et al (2013) and Yue et al (2014). Lastly, the exclusion of raw material extraction is evidenced in the GTG scope, which is usually applied to end-of-life products supply chains.…”

This chapter describes how to optimise energy systems considering their economic and environmental performance simultaneously. To this end, we follow an approach that combines life cycle assessment with multi-objective optimisation. We illustrate how to apply such a framework to the strategic design and planning of biofuel supply chains. The problem is formulated in mathematical terms as a multi-objective mixed-integer linear programme. The aim of the design/planning task is to maximise the net present value while the environmental impact is minimised simultaneously. Eco-indicator 99 is the life cycle assessment methodology incorporated in the model to quantify the environmental damage. The implementation of the algorithm in a case study based on the Argentine industry reveals the conflictive trade-off between economic and environmental objectives. The proposed framework provides valuable insight into the incidence of key operational features in the optimal biofuel supply chain network.

“…For instance, Jia et al (2006) employed MO optimization in the context of cleaner production, and Erol and Thöming (2005) for the eco-design of reuse and recycling networks. Recent publications (Guillén-Gosálbez and Pozo et al, 2012;Ruiz-Femenia et al, 2013) employed it in the optimization of chemical supply chains. The subject of the study by García and Caballero (2011) was an economic and environmental assessment of various alternatives for extracting acetic acid from water.…”

This multidisciplinary study concerns the optimal design of processes with a view to both maximizing profit and minimizing environmental impacts. This can be achieved by a combination of traditional chemical process design methods, measurements of environmental impacts and advanced mathematical optimization techniques. More to the point, this paper presents a hybrid simulation-multiobjective optimization approach that at once optimizes the production cost and minimizes the associated environmental impacts of isobutane alkylation. This approach has also made it possible to obtain the flowsheet configurations and process variables that are needed to manufacture isooctane in a way that satisfies the above-stated double aim. The problem is formulated as a Generalized Disjunctive Programming problem and solved using state-of-the-art logic-based algorithms.It is shown, starting from existing alternatives for the process, that it is possible to systematically generate a superstructure that includes alternatives not previously considered. The optimal solution, in the form a Pareto curve, includes different structural alternatives from which the most suitable design can be selected. To evaluate the M

“…Searching for a single schedule for all scenarios is often used in the robust literature [9]. However, a less conservative option is using a multi-stage stochastic optimization [16], which benefits from the assumption that the uncertainty can be measured in the short future, so decisions could be adapted accordingly. Hence, we propose a two-step scheduling approach for the evaporation network considering uncertainty in the outdoor weather and production plan.…”

Abstract-Considering uncertainty in continuous production processes is key to compute short-time optimal schedules which can be trusted in practice. This paper proposes a twostep stochastic approach to the robust scheduling of several evaporation plants. This approach considers the possibility of reacting in the future once the uncertainty materializes. Each evaporator has different features (capacity, equipment, etc.) and the individual performance is affected by external factors and fouling effects. Moreover, a multi-objective analysis has been carried out to provide a decision support for the operator who must take the concrete decisions about load allocation and cleaning tasks along a time horizon. The problem has been solved by discretizing the time horizon and adapting the general-precedence method to deal with an unknown number of tasks. The nonlinear behavior of each plant is approximated by surrogate linear models obtained experimentally, providing thus solutions in acceptable time.
