A novel heuristic simulation‐optimization method for critical infrastructure in smart transportation systems

Abstract

Summary A simulation‐based optimization is a decision‐making tool that helps in identifying an optimal solution or a design for a system. An optimal solution and design are more meaningful if they enhance a smart system with sensing, computing, and monitoring capabilities with improved efficiency. In situations where testing the physical prototype is difficult, a computer‐based simulation and its optimization processes are helpful in providing low‐cost, speedy and lesser time‐ and resource‐consuming solutions. In this work, a comparative analysis of the proposed heuristic simulation‐optimization method for improving quality‐of‐service (QoS) is performed with generalized integrated optimization (a simulation approach based on genetic algorithms with evolutionary simulated annealing strategies having simplex search). In the proposed approach, feature‐based local (group) and global (network) formation processes are integrated with Internet of Things (IoT) based solutions for finding the optimum performance. Further, the simulated annealing method is applied for finding local and global optimum values supporting minimum traffic conditions. A small‐scale network of 50 to 100 nodes shows that genetic simulation optimization with multicriteria and multidimensional features performs better as compared to other simulation‐optimization approaches. Further, a minimum of 3.4% and a maximum of 16.2% improvement is observed in faster route identification for small‐scale IoT networks with simulation‐optimization constraints integrated model as compared to the traditional method. The proposed approach improves the critical infrastructure monitoring performance as compared to the generalized simulation‐optimization process in complex transportation scenarios with heavy traffic conditions. The communicational and computational‐cost complexities are least for the proposed approach.

Network Analysis for Projects with High Risk Levels in Uncertain Environments

“…Intuitionistic fuzzy set theory deals with both membership and nonmembership values. Neutrosophic set theory developed by Smarandache treats uncertainty and ambiguity by adding indeterminacy-membership functions, in addition to truth-membership and falsity-membership functions [18][19][20][21][22].…”

A Novel Smart Healthcare Design, Simulation, and Implementation Using Healthcare 4.0 Processes

“…Challenges identified in blockchain-based smart healthcare literature surveys are: (i) lack of proper knowledge in healthcare system users to effetively and securly storage of data, and access as and when required, (ii) lack of standard data collection templates, sharing platforms, peer-to-peer connectivity systems, trust in existing healthcare system etc. (iii) proper dynamic framework that ensures secure data migrations from present healthcare system to smart healthcare system, (iv) many developing countries lacks in intentions to provide corruption free or unethical economic benefit based health services, (v) management of EHR, EMR or PHR, (vi) custodian based secure data accessibility, (vii) connectivity among medical technologists to help in developing full-proof system, (viii) many countries do not have standarization policies for cryptocurrencies, (ix) secure management of data in densly populated regions or countries, (x) users are not interested to invest in companies which can handle their historical or ancestral records on payment basis even by knowing that they themselve are not able manage their records which are very much necessary in any treatment, (xi) lack in technological solutions like (usage of industry 4.0 or simulationoptimization) in healthcare for making it advanced and secure [39]- [41], (xii) a large number of data leakage and unethical advantages are observed in present healthcare system, and (xiii) unmanaged present healthcare system with failures, thefts, eavesdropping, spoofing, impersonation or other cybercrimes.…”
