New Adaptive Surrogate-Based Approach Combined Swarm Optimizer Assisted Less Tuning Cost of Dynamic Production-Inventory Control System

Abstract

Today, most manufacturing control systems are complex and expensive, so they are limited to employ a small number of function evaluations for optimal design. Yet, looking for optimization methods with the less-computational cost is an open issue in engineering control systems. This paper aims to propose an effective adaptive optimization approach by integrating Kriging surrogate and Particle Swarm Optimization (PSO). In this method, a novel iterative adaptive approach is utilized using two sets of training samples including initial training and adaptive sample points. The initial training points are designed by space-filling design, while the adaptive points are generated using a new jackknife resampling approach. The proposed approach can effectively convergence towards the global optimal point using a small number of function evaluations. The efficiency and applicability of the proposed algorithm are evaluated using the optimal design of the fractional-order PID (FOPID) controller for some benchmark transfer functions. Then, the introduced approach is applied for tuning the parameters and the sensitivity analysis of the FOPID controller for a dynamic production-inventory control system. The results are in good agreement with the results reported in the literature, while the proposed approach is executed with a lower computational burden.

Computational Intelligence Assisted Less-Expensive Privacy-Preserving Optimization in Audio-Video Content

“…Recent studies and literature have increasingly emphasized the advantages of utilizing metamodels in various engineering design applications, including audio-visual speech recognition. This growing preference for metamodels over alternative methods is primarily driven by the escalating complexity of real-world systems, which often require approximation techniques that are both accurate and cost-effective, as cited in [2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Metamodeling techniques are intricately linked with the Design and Analysis of Computer Experiments (DACE).…”

PID Tuning Using Differential Evolution With Success-Based Particle Adaptations

“…Since then, several algorithms have been studied/proposed, among which Particle Swarm Optimization (PSO) and Differential Evolution (DE) schemes have received systematic attention from the community. For instance, within the class of swarm-inspired algorithm, [23] used PSO for PID optimization in hypersonic vehicle control, [24] used Quantitative Feedback Theory (QFT) and PSO for a DC-DC converter, [25] used Kriging surrogates and PSO for fractional order PID in a production-inventory control system, [26] used PSO in magnetic-levitation control, [27] approached the electro-hydraulic servo control system, [28] combined GA and PSO for Gaussian adaptive PID control of a DC-DC converter, [29] modified the inertia weight of PSO as a piecewise nonlinear function to consider the effects of PID parameters on control response, [30] used a fractional order PSO in which the velocity term implements a non-integer order equation to smooth the transition and exploration of the search space.…”

Digital-Twins Towards Cyber-Physical Systems: A Brief Survey

“…Since digital twins frequently employ intricate mathematical models, it is difficult to apply efficient optimization techniques, such as non-linear multiresponses constrained optimization [74]- [77], real-time intelligent control [7], [78]- [81], robust uncertainty management [39], [82], due to their high processing requirements. Most simulations used in real-world DT require a lot of computational costs to assess the various unknown model functions [83].…”
