fuzzy logic technique

Evolutionary computation algorithms can also be considered at compile time to identify the optimal setting of controlling parameters over execution time. Main steps of a smart production surveillance workflow. Future trends will see diversification to fuzzy-neural applications as well as the aesthetic aspects of the garment design. Statistical analysis (Social susceptibility): Correlation analysis was carried out by comparing time series of demographic and health-related data with respect to time series of meteorological data. Besides, the abovementioned features would lead the neural networks to solve complex problems precisely and flexibly and provide a suitable basis for the control of complex systems. The self-organizing map and fuzzy clustering algorithm was used to automatically separate coloured patterns for independent evaluations. The goal is to get a continuous variable from fuzzy truth values. Until 1995, Bolzano had less than five tropical nights per year, whereas 20 tropical nights were recorded in 2010. (1996) used the artificial neural network as a non-linear tool to predict colour matches on polyester yarns dyed using three different dyestuffs. Fuzzy logic works with membership values in a way that mimics Boolean logic. This is why fuzzy logic is a highly promising possibility within the CAD application area but still requires more research to achieve its full potential. In mathematical logic, there are several formal systems of "fuzzy logic", most of which are in the family of t-norm fuzzy logics. Fuzzy logic with evaluated syntax (sometimes also called Pavelka's logic), denoted by EVŁ, is a further generalization of mathematical fuzzy logic. The generalization of AND is known as a t-norm. (5.2) followed by the evaluation of the resulting linguistic variables which determines the degree of membership of each input variable. For instance the following are some notable application of Fuzzy logic reasoning technique in the domain of medical diagnosis. It gives tremendous impact on the design of autonomous intelligent systems. Lotfi A. Zadeh argues that fuzzy logic is different in character from probability, and is not a replacement for it. Fuzzy logic and probability address different forms of uncertainty. Drinkwater and Horvath, 1979; Basu and Samet, 2002, A composite indicator was applied which combines different factors, using the semiquantitative, Use of artificial neural networks (ANNs) in colour measurement, Power Electronics Handbook (Fourth Edition). The applications provide excellent solutions for monthly decisions, but in today's DOF we use real-time data. The control algorithms in Matlab environment exchange data in real-time with the thermal models and ENVI-met, through the Building Control Virtual Test Bed (BCVTB) software. Fuzzification is the process of assigning the numerical input of a system to fuzzy sets with some degree of membership. Potential heat wave impact index for the districts of Bolzano. It provides us linguistic representation such as slow and fast and thus uses truth degree, which are represented as grade of a membership function. (2000). Fundamentally, fuzzy logic based CDSS have been successfully deployed to solve a number of real life diagnostic challenges. The term fuzzy logic was introduced with the 1965 proposal of fuzzy set theory by Lotfi Zadeh. Dr Lotfi Zadeh developed the FL idea in the 1960s from the University of California. 5.16. A potential distributed optimization approach, which uses less decision variables might not take under consideration, for example, the effect of fresh intake air to the thermal comfort and thus the energy required to achieve good comfort during the next steps. Energy Build 2016;123:119–35. [citation needed], This would be easy if the output truth values were exactly those obtained from fuzzification of a given number. Thus, to ensure FC lifetime prolongation by preventing the FC system from load changes with high frequencies, researchers applied different frequency decoupling techniques. Valiant essentially redefines machine learning as evolutionary. How to elicit fuzzy data, and how to validate the accuracy of the data is still an ongoing effort strongly related to the application of fuzzy logic. The input to both methods were the K/S values obtained from the spectral reflectance data taken from each yarn sample using a spectrophotometer. However, there are also propositions with variable answers, such as one might find when asking a group of people to identify a color. The developed control algorithms are based on. The more you sleep (i.e., the device enters low and deep power sleep modalities), the less energy you consume. [53,67] regulated the energy management in PEMFC/UC and PEMFC-/battery-/UC-powered hybrid vehicular systems using fuzzy logic.

Pairs of input and output vectors are presented to the input and output layers of the networks respectively. These are generally adverbs such as very, or somewhat, which modify the meaning of a set using a mathematical formula. This data can be combined with daily production of both water and oil, and displayed as a pie chart. Therefore, this temperature has 0.2 membership in the fuzzy set "warm" and 0.8 membership in the fuzzy set "cold". Hybrid systems can provide improved efficiency when a well-designed energy splitting algorithm that considers the individual characteristics of each hybrid system is applied. The dashboard and layout should include important information affecting the current operations, and it should be concise and well organized so that managers, supervisor, engineers, and technician can easily read and decipher the displayed information. Fuzzy sets are often defined as triangle or trapezoid-shaped curves, as each value will have a slope where the value is increasing, a peak where the value is equal to 1 (which can have a length of 0 or greater) and a slope where the value is decreasing. The traditional method uses individual, single dyeings as the input data to ‘train’ or establish the model and the dye recipe is expressed as a linear combination of the single-dyes. The graph shows the increase of the annual average temperature as yearly values (gray line) and smoothed as 20 year average (blue line) in the last 150 years since 1850. If this optimization is performed over a fixed driving cycle, a global optimum solution can be found. Boxplots that visualize the distribution of the daily number of hospital emergencies/admissions according to these exposure factors confirmed that there is no extraordinary difference between hotter and less hot days. This degree of membership may be anywhere within the interval [0,1]. There are mainly two types of adaptive controllers: feedforward and feedback adaptive controllers. (5.1). 5.18. The performance of the control algorithms in reducing the energy consumption and in providing comfortable indoor conditions has been assessed, by linking the control algorithms with the simulation models for the interior and exterior environment (Fig. Nevertheless, the land-surface temperature may indicate areas representing an urban heat island effect. In the literature, many researchers applied fuzzy logic approach for hybrid systems with PEMFC for different applications. Artificial Intelligence - Fuzzy Logic Systems - Tutorialspoint By scaling power voltage and clock frequency, the power consumption of the device reduces. The basic approach for this issue is inserting a transfer function for a delay with a suitable time constant (first-order low-pass filter). Another purpose of the control system is to adopt the battery or UC bank in stabilizing the dc link voltage. On the other hand, a neural network can model the non-linear interactions but requires a larger ‘training’ set to establish the model. This makes fuzzy logic able to tackle automation of procedures such as startup and setting of parameters, for which few approaches were previously available. Duty cycling. In general use, ecorithms are algorithms that learn from their more complex environments (hence eco-) to generalize, approximate and simplify solution logic. Delete spikes, frozen, out-of-range data, and populate missing data with physical (logical) information using well performance (nodal analysis) or ANN. The structure of the neural network was set up to have thirty-one input nodes for the K/S spectral values, fifteen middle-layer nodes, and three output nodes. It is done by Aggregation of data and changing into more meaningful data … Although the absolute measurement of each operational risk is not as reliable as the measurement of market risks, the relative levels of each risk provide useful information for determining the relative investment in managing each risk. When the truth value of one component of a conjunction or disjunction is increased or decreased, the other component is decreased or increased to compensate. Because of the abovementioned features, the Haar wavelet transform is the most suitable functions for filtering HEV power demand load profile, which consists of transients corresponding to sharp peak power demand. [25] Ecorithms and fuzzy logic also have the common property of dealing with possibilities more than probabilities, although feedback and feed forward, basically stochastic weights, are a feature of both when dealing with, for example, dynamical systems. The development of these algorithms is made using Matlab, since it provides the appropriate libraries and graphical representation of the controls behavior. In order to use the neural network to predict any type of value, it has to be trained with known values for the input and output parameters. For each truth value, cut the membership function at this value, Combine the resulting curves using the OR operator, Find the center-of-weight of the area under the curve. McGregor et al. Figs. (5.4) to arrive at the defuzzified output which reflects the final diagnoses outcome. Fuzzy models or sets are mathematical means of representing vagueness and imprecise information (hence the term fuzzy). There is no single algorithm for this purpose. Like fuzzy logic, they are methods used to overcome continuous variables or systems too complex to completely enumerate or understand discretely or exactly. Considering stringer air pollution laws, operating points with high emissions are heavily penalized. The most important propositional fuzzy logics are: These extend the above-mentioned fuzzy logics by adding universal and existential quantifiers in a manner similar to the way that predicate logic is created from propositional logic. These rule weightings may be static or can be changed dynamically, even based upon the output from other rules. This approach allowed for an assessment and comparison of the social vulnerability of the five districts of Bolzano, considering spatial exposure and social susceptibility. We say that s is decidable if both s and its complement –s are recursively enumerable. Reproduced from Kolokotsa D, Gobakis K, Papantoniou S. Development of a web based energy management system for University Campuses: the CAMP-IT platform. It must be acknowledged that the index values refer to the local reality and, therefore, they have to be interpreted in a comparative way, e.g., as a ranking rather than as absolute values. Thus the question of a suitable extension of them to fuzzy set theory is a crucial one. Compared to the conventional 2 state reasoning technique, Fuzzy logic has the capability to provide more exact and reliable results especially in the domain of CDSS where accuracy and reliability are of top priority. The algorithm for the control of the lighting can dim or turn on/off the luminaires, depending on the available daylight and the desired lighting levels. As a contribution to the studies of Erdinc et al. Later, some other models arose like the Buckles-Petry model, the Prade-Testemale Model, the Umano-Fukami model or the GEFRED model by J.M. Successively, L. Biacino and G. Gerla argued that the proposed definitions are rather questionable. FIGURE 8.6. Hospital emergency/admission data were divided by gender and age in order to focus on different subgroups. Track actions and automatically identify well events, that is, automatically recognize that a well test has started by understanding the pressure buildup without human intervention, or identifying a rig or workover intervention. Tracking actions and well events using expert systems, pattern recognition, and predictive advisory tools. This system also acquires the designer's and the consumer's perceptual data in a different but more systematic way. FL is based on the system understanding the natural language or human … An artificial neural network with Bayesian regularization training technique was developed to predict colour appearance (from colorimetric attributes to colour-appearance attributes) by Xin et al. The algorithm for the indoor environmental quality, controls the HVAC using the difference of the PMV index parameters (temperature, humidity, radiation, air velocity, metabolic rate, and clothing) and the difference of the CO2 concentration level from the required ones, in order to change the heating/cooling system or increase/decrease the flow of fresh air through the ventilation system. The algorithm for the thermal comfort uses the PMV index parameters (temperature, humidity, radiation, air velocity, metabolic rate, and clothing), in order to adjust the heating/cooling system or increase/decrease the flow of fresh air through the ventilation system. This is basically because fuzzy systems lack the ability to learn when confronted with an entirely new situation. The power sharing between the FC system and energy storage system (battery or UC bank) is determined according to the load sharing and control algorithm. In order to solve this, an extension of the notions of fuzzy grammar and fuzzy Turing machine are necessary. Various flexible control methods and intelligent techniques are used for optimization, subject to system constraints. where μY(xi) is the membership value of xi as given by the membership function and xi is the center of the membership function. The degree of membership assigned for each fuzzy set is the result of fuzzification. (5.3) has been widely adopted [16]. While a, b, and c are the parameters of the membership function. Axiomatization of EVŁ stems from Łukasziewicz fuzzy logic. If it is 0 then the value does not belong to the given fuzzy set, and if it is 1 then the value completely belongs within the fuzzy set. Fuzzy Logic is used with Neural Networks as it mimics how a person would make decisions, only much faster. Product fuzzy logic is the extension of basic fuzzy logic BL where conjunction is product t-norm. Besides, wavelet transform provides a quadratic mirror filtering application and the loss of important edge information is minimized compared with conventional filtering techniques. Computational theorist Leslie Valiant uses the term ecorithms to describe how many less exact systems and techniques like fuzzy logic (and "less robust" logic) can be applied to learning algorithms. Main factors that can impact net present value (NPV) and internal rate of return (IRR) include underperforming wells, ESP, GL, PCP, compression, and other facilities that are down, poor data quality, and nonproductive time (NPT) team member. Various researchers have applied techniques to fine-tune a fuzzy controller’s knowledge base, many using other AI disciplines such as Genetic Algorithms or neural networks. All decision variables including the energy demand are normalized in the range [0,1] by dividing them with its maximum value. The complex relationship between basic sensory descriptors and fashion themes, given by consumers, is modeled using fuzzy cognitive maps, which are a robust and interpretable tool for modeling a consumer's cognition about the causal relations between fashion themes and body shapes. {\displaystyle \rightarrow } Vila et al. An FCEV energy control system must provide good acceleration and high recovery of braking energy. (2002). Fuzzy logic is a very robust artificial intelligent technique for forecasting load on a long-term basis as described in [6]. In the paper,[11] a criterion has been formulated to recognize whether a given choice table defines a fuzzy logic function and a simple algorithm of fuzzy logic function synthesis has been proposed based on introduced concepts of constituents of minimum and maximum. The colored dashed graphs in Figure 8.5 represent the results of various climate scenarios for South Tyrol. Therefore, the results require a validation check in order to be used in heat wave studies that are mainly dealing with air temperature values. [86] applied PI controller for the power electronics converter duty cycle determination in order to regulate the desired values of the system parameters determined by a nonlinear flatness-based supervisory control approach. The standard min–max composition operation of fuzzy relations is used for aggregating the different fuzzy relevancy degrees obtained from the previous fuzzy decision trees and cognitive maps and for building an overall evaluation criterion for new personalized design schemes. FUZZY LOGIC FUNDAMENTALS 3.1 INTRODUCTION The past few years have witnessed a rapid growth in the number and variety of applica-tions of fuzzy logic (FL). It is employed to handle the concept of partial truth, where the true value may range between completely true and completely false. This cost function generally represents the fuel consumption or emissions especially for vehicular applications. In fact, for a CMOS technology the power consumption scales quadratically with the voltage and linearly with the working frequency [4]. R. Ng, in Soft Computing in Textile Engineering, 2011. It has also been used in recognition of hand-written symbols in Sony pocket computers, flight aid for helicopters, controlling of subway systems in order to improve driving comfort, precision of halting, and power economy, improved fuel consumption for automobiles, single-button control for washing machines, automatic motor control for vacuum cleaners with recognition of surface condition and degree of soiling, and prediction systems for early recognition of earthquakes through the Institute of Seismology Bureau of Meteorology, Japan. [79] presented an experimentally applied equivalent fuel consumption minimization strategy aiming at minimizing the hydrogen consumption while maintaining drivability in a PEMFC/UC hybrid vehicular system. The Centroid of Area (CoA) defuzzification technique defined in Eq. FL techniques have been used in image-understanding applications such as detection of edges, feature extraction, classification, and clustering. Fig. The demographic dataset was split into various subgroups according to age and gender. (2013) have generated a production deferments reports driven by exception-based surveillance process by recommending a series of associated well remedial actions which have resulted in an 8% production gain. Most importantly, fuzzy logic CDSS usually lack the capability to perform well when presented with an entirely new data sample that is not considered when formulating the rule base. Machine learning and fuzzy logic can be fruitfully considered here to control the energy consumption of the system by adaptively acting on the sampling rates of sensors by also taking into account predictions for both the residual and the harvestable (in the future) energy. The WT decomposes into various components at different time intervals and frequency bands as a windowing technique. The indicators used are those proposed by Kropp et al. This enables power transfer to/from battery or UC bank and improves the driving performance. Medina, M.A. [81] for FC/battery/UC hybridization for a vehicle in a simulated environment. In such cases, membership in a set is a matter of degree. Voltage/frequency scaling. number of events with three consecutive days of maximum temperature ≥ 30° C, NoTN - Number of tropical nights, i.e. 4). The case study focuses on the social dimension of vulnerability. In the background, display the total cumulative oil or gas to mimic the drainage area extrapolated at reservoir conditions with active links to the well and field data, along with metrics on well events including downtime. There are many techniques for energy management that have been investigated in the literature, such as intelligence-based strategies, optimization-based strategies, and frequency decoupling strategies [74]. In contrast with an adaptive control policy, a robust control policy is static; rather than adapting to measurements of variations, the controller is designed to work assuming that certain variables will be unknown [15]. The following list summarizes the major capabilities and characteristics of a smart production surveillance system: Manage a large spectrum of real-time production and pressure data. He concluded that the fuzzy logic appears to be effective in dealing with ambiguity and uncertainty in cotton colour grading. So to speak, fuzzy logic technology is a computer-based approach to many modern systems. While the above kinds of fuzzy logic have traditional syntax and many-valued semantics, in EVŁ is evaluated also syntax. The optimal operating point can be obtained using a weighted-sum approach to optimization of the conflicting objectives. [67]; however, they optimized the parameters of their FLC for an optimal energy control. The orange arrow (pointing at 0.2) may describe it as "slightly warm" and the blue arrow (pointing at 0.8) "fairly cold". In a narrow sense, fuzzy logic is a logical system, which is an extension of multivalued logic. Erdinc et al. 5.15 and 5.16 show field-level KPIs and well-level KPIs that can be monitored and improved by smart surveillance to improve business model performance. For example, we can use the hedges rather and somewhat to construct the additional values rather old or somewhat young. where μA(xi) is the membership function of xi in A and μA is the degree of membership of xi in A. As an example, Thounthong et al. An index value of 0.98 signifies that the susceptibility in the district Europa/Novacella is relatively higher than in S. Giovanni/Don Bosco or any other district. Because of the capacity of interpretation and robustness of the proposed fashion recommender system, fuzzy logic constitutes the main computational tool for the formalization and modeling of perceptual data and their relations. One has then to decide for a number that matches best the "intention" encoded in the truth value. Use pattern recognition with expert rules to build a knowledge-capture system and generate solutions for troubleshooting and well remediation. Connected to this well schematic, the production plot versus the latest 30 days is plotted highlighting the maximum and minimum allowable values (derived from reservoir studies at the maximum bottom-hole drawdown pressure) and the minimum production that satisfies the economic evaluation. 5.14. [76], Eren et al. The defuzzification component receives as input the output of the inference engine and applies Eq. The aim of these interviews was to collect information on awareness issues, experience with heat waves in the recent past, existing monitoring and forecast systems, and information flow issues between different institutions but also media and the population.
