“…The main idea is to use a pre-computed database consisting of optimised speed profiles in order to avoid duplicative optimisation for the same taxiway segments. A similar concept of pre-computation and storage of solutions to speed up the on-line optimisation procedure has been observed in other application domains, for example see (Lewis et al, 2009;Wagner et al, 2013;Sanders and Schultes, 2007). The main difference and novelty of the proposed approach in this paper compared to those methods will be discussed in Section 2.4.…”

“…Otherwise, the evaluation of the previously found similar layout is used as a building block and only the difference in the layout is calculated. Multi-objective optimisation of RFID antennas presented in (Lewis et al, 2009) employs a similar approach, in which a database of previously evaluated solutions is filled during the search. Memoization for image processing (Khalvati et al, 2011) divides an image and stores fixed-sized building blocks of pixels so that they can be reused during on-line image processing.…”

Airports face challenges due to the increasing volume of air traffic and tighter environmental restrictions which result in a need to actively integrate speed profiles into conventional routing and scheduling procedure. However, only until very recently, the research on airport ground movement has started to take into account such a speed profile optimisation problem actively so that not only time efficiency but also fuel saving and decrease in airport emissions can be achieved at the same time. It is envisioned that the realism of planning could also be improved through speed profiles. However, due to the multi-objective nature of the problem and complexity of the investigated models (objective functions), the existing speed profile optimisation approach features high computational demand and is not suitable for an on-line application. In order to make this approach more competitive for real-world application and to meet limits imposed by International Civil Aviation Organization for on-line decision time, this paper introduces a pre-computed database acting as a middleware to effectively separate the planning (routing and scheduling) module and the speed profile generation module. Employing a database not only circumvents duplicative optimisation for the same taxiway segments, but also completely avoids the computation of speed profiles during the on-line decision support owing a great deal to newly proposed database initialization procedures. Moreover, the added layer of database facilitates, in the future, more complex and realistic models to be considered in the speed profile generation module, without sacrificing on-line decision time. The experimental results carried out using data from a major European hub show that the proposed approach is promising in speeding up the search process.

“…Following the promising results from the use of ACO on the single objective of improving antenna efficiency, the method was refined to use local search techniques to further improve efficiency [22], and then extended to a multi-objective formulation of the problem, simultaneously optimising efficiency and resonant frequency [13,12]. As previously noted, one of the crucial performance criteria for RFID tags is their read range, which is directly proportional to the wavelength used.…”

This paper presents a generalised parametrisation as well as an approach to computational optimisation for small, planar antennas. A history of previous, more limited antenna optimisation techniques is discussed and a new parametrisation introduced in this context. Validation of this new approach against previously developed structures is provided and preliminary results of the optimisation are demonstrated and discussed. For the optimisation, a binary MultiObjective Particle Swarm Optimisation (MOPSO) is used and several methods for generating a viable initial population are introduced and discussed in the context of practical limitations computational simulations.

“…The detailed design parameters of the antenna with a quasi-isotropic radiation pattern were optimized by using a Pareto GA and the IE3D EM simulator for a tag antenna operating in the UHF band [11]. On the other hand, an ACO algorithm was proposed to optimize both efficiency and resonant frequency in RFID antennas [12]. Similarly, a multi-objective version of extreme optimization (EO) was employed to maximize efficiency and minimize resonant frequency [13].…”

RFID technology is one of the major core competencies for Internet of Things (IOT). Organizational strategies focus on improving the management efficiency as well as reducing the operational cost to maintain profit margins. Therefore, the performance of RFID systems has attracted researchers' attention. A variety of soft computing techniques have been employed to improve effectiveness and efficiency in various aspects of RFID systems. Meanwhile, an increasing number of papers have been published to address related issues. The aim of this paper is to summarize the findings by a systematic review of existing research papers concerning the application of soft computing techniques to RFID technology.
