“…This graph consists of straight lines because of the linear relationship between MOPC and weighting factor, as explained by Jain and Bandyopadhyay. 50 Each line depicts the relationship between the weighting factor and MOPC at a particular pinch point for a particular zone. The intersection of these lines provides the range of weighting factors for which different prioritizing sequences are obtained (Figure 2).…”

“…The multiple objectives are represented with a single-objective function by aggregating different objectives, and the pinch concept is used to determine the prioritization of different zones, depending on the selection of the coefficients. Jain and Bandyopadhyay later extended this approach for multiobjective segregated targeting problems and also to account for the changes in the pinch quality or pinch jump. The advantage of the approach is that it could identify the entire Pareto-optimal front for the problem without having to solve the problem for each perturbation of the objective.…”

“…ERs are visualized as the resources that are likely to optimize the problem further as they are shared between every zone and, unlike dedicated resources, are not specific to a particular zone. This paper adopts the concepts of multiobjective pinch analysis developed by Jain and Bandyopadhyay to extend segregated targeting problems with ERs for MOO. The introduction of multiple objectives makes the problem more practical and helps in informed and better decision-making.…”

Resource conservation strategies play a vital role in the manufacturing and process industries to fulfill environmental discharge and societal responsibilities. This paper aims to conserve resources with multiple objectives in a constrained source–sink resource conservation network. A special type of network, known as segregated targeting problems with multiple external resources (ERs), is considered in this work. The problem contains a set of zones with their own demands and a dedicated resource specified for individual zones. A set of internal sources which are available freely for reuse, as well as the ERs, are also available to be shared among all the zones. The purpose of this work is to apply pinch analysis principles for optimizing the multiple objectives associated with multiple resources in a segregated targeting problem. The first step includes the targeting of each zone individually without considering ERs for maximum internal reuse efficiency and to determine the pinch points of each zone. Using these pinch points, a novel prioritizing indicator, termed the multiobjective extended prioritized cost, is proposed in this work. The indicator identifies the zones’ targeting sequences graphically and dictates the addition of ERs to different zones to optimize multiple objectives simultaneously. The Pareto-optimal solutions for the problem are identified by graphical visualization based on different weighting coefficients. Two different examples, a representative case study and a water conservation network, demonstrate the proposed methodology. The proposed method is applicable in conserving multiple resources in a constrained source–sink reuse network considering multiple objectives.

“…Iterative Pinch Analysis to address non-linearity in a stochastic Pinch problem was very recently studied by Arya and Bandyopadhyay [70]. Jain and Bandyopadhyay [71] developed multi-objective optimisation for segregated targeting problems using Pinch Analysis, which again extends the scope of Process Integration.…”

The strong demand for sustainable energy supplies had escalated the discovery, and intensive research into cleaner energy sources, as well as efficient energy management practices. In the context of the circular economy, the efforts target not only the optimisation of resource utilisation at various stages, but the products’ eco-design is also emphasized to extend their life spans. Based on the concept of comprehensive circular integration, this review discusses the roles of Process Integration approaches, renewable energy sources utilisation and design modifications in addressing the process of energy and exergy efficiency improvement. The primary focus is to enhance the economic and environmental performance through process analysis, modelling and optimisation. The paper is categorised into sections to show the contribution of each aspect clearly, namely: (a) Design and numerical study for innovative energy-efficient technologies; (b) Process Integration—heat and power; (c) Process energy efficiency or emissions analysis; (d) Optimisation of renewable energy resources supply chain. Each section is assessed based on the latest contribution of this journal’s Special Issue from the 21st conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES 2018). The key results are highlighted and summarised within the broader context of the state of the art development.
