“…Almost every society in the world struggles with the availability and efficient allocation of healthcare resources. Healthcare service delivery gaps were investigated by Basu, Jana, Bardhan, and Bandyopadhyay ( 2017 ) using pinch analysis, a quantitative tool developed to optimize source-demand allocation networks. Lai, Cheung, and Fu ( 2018 ) designed a new mechanism to optimize the allocation of public healthcare resources by utilizing a team-DEA model.…”

As one of the most complicated and challenging networks among healthcare systems, the organ transplant network necessitates an effective supply chain network design. In this article, a bi-objective mixed integer nonlinear programming (MINLP) location-allocation model is proposed to design the organ transplant supply chain network, with the objectives of minimizing overall costs (including strategical and operational costs) and the number of unsatisfied demands under uncertainty. The developed model calculates the optimum number of facilities to be established and equipped for each organ, the flows between them, and the optimal allocation of cold chain vehicles, which is a combination of similar works in this context with cold chain and resource allocation as one of the novelties of this paper. Moreover, the preciousness of human life necessitates a policy for allocating organs. Hence, in this study, high-risk recipients, who are more likely to die in case of unmet demand, are prioritized above low-risk ones to prevent mortality as much as possible. This article also takes transportation constraints into account in the effort to minimize carbon emissions, one of the most challenging environmental concerns of the present day. Numerical experiments demonstrate the applicability of the developed model, and a case study is presented to compute the optimal solutions of the proposed methodology. Finally, various sensitivity analyses are performed to provide managerial insights.

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.

Pinch Analysis helps in achieving sustainable development through conserving resources in various source–sink resource conservation networks. Diverse applications and methodologies of Pinch Analysis primarily consider only exact and precise parameters without accounting for variabilities and uncertainties. With the unavailability of past data and lack of proper understanding of different operations involved, designers have to account for epistemic uncertainties during synthesizing source–sink networks. Such epistemic uncertainties can be represented as interval numbers, with upper and lower limits. An interval linear programming formulation, incorporating uncertain network parameters as interval numbers, is developed in this paper to address resource conservations in real-world problems. Two alternate approaches, a fuzzy satisfaction approach and a novel best–worst method, are proposed and solved using the principles of Pinch Analysis. Proposed methodologies to address the interval Pinch Analysis are illustrated through diverse examples (such as water conservation networks, industrial solvent selections to reduce environmental risk, and biochar-based carbon management networks), and proposed approaches are compared. It is concluded that the range of optimal resource requirement is lower for the best–worst approach with significantly reduced options for topological trap due to pinch-jump. Furthermore, the underlying physical understandings of Pinch Analysis are explored, and their implications to appropriately handle epistemic uncertainties during the synthesis of such networks are demonstrated.
