Cost Optimal Segregated Targeting Problems with Dedicated Sources

Abstract

Pinch analysis is a well-established technique to achieve sustainable development through conservation of various resources. The techniques of pinch analysis are also applied for cost minimisation in several problems as cost-effectiveness plays a major role in decision making for any industry. In this paper, cost optimality of a special kind of resource allocation problem, called segregated targeting problem with dedicated sources, is addressed. A segregated targeting problem consists of multiple set of demands called zones and a set of common internal sources. Dedicated sources are the internal sources which are specific to a zone in which they are present and are not shared with other zones. A mathematically rigorous methodology is developed in this paper and a quantity with the dimension of per unit cost that sets the preference for the distribution of flow from different sources to demands is identified. The applicability of the proposed methodology is demonstrated through three illustrative examples from diverse domains: carbon constrained energy sector planning, water allocation network, and integrated iron and steel mill.

Interval Pinch Analysis for Resource Conservation Networks with Epistemic Uncertainties

“…85 A topology trap restricts the evolution of a synthesized network to reach global optimum or to achieve flexibility. 86 Implications of pinchjumps were pointed out in several resource conservation studies such as process modifications, 34 targeting for multiple resources, 87 carbon-constrained energy sector planning, 88 zero wastewater discharge systems, 89 heat and power integration, 90 production planning, 91 segregated targeting problems, 92 etc. The topology trap due to pinch-jump should be considered while synthesizing resource conservation networks, especially to account for the uncertainties.…”

Multiobjective Pinch Analysis for Resource Conservation in Constrained Source–Sink Problems

“…Chandrayan and Bandyopadhyay 34 then proposed the concept of prioritized cost, based on the work by Shenoy and Bandyopadhyay, 35 to arrange the zones and target each zone to account for the overall economic feasibility of the problem. Considering the dedicated sources in segregated targeting problems that can be used only in particular zones, Jain and Bandyopadhyay 36 introduced the benefit number concept based on pinch analysis principles to target the zones, and later Jain and Bandyopadhyay 37 introduced the cost-based benefit number considering cost as the main criteria to determine the cost-effective resource allocation to the zones. These concepts are beneficial for decision-makers to determine which zone should be prioritized to achieve minimum fresh resource requirement or minimum cost.…”
