Abstract
Purpose
The purpose of this paper is to analyze integrally the effect of factors, such as management behavior, organizational climate, and self‐efficacy, on shaping the customer‐oriented behavior of employees, and verify the assumptions based on the linear multivariate statistical analysis and non‐linear fuzzy neural network model.
Design/methodology/approach
The top‐five life insurance companies (based on the percentage of market share) in Taiwan were selected as the population, to verify the assumptions based on the linear multivariate statistical analysis and non‐linear fuzzy neural network model.
Findings
The results showed that managers who emphasize self‐efficacy are more inclined to customer‐oriented behavior under intrinsic motivation than extrinsic motivation, and both the self‐efficacy and organizational climate have positive and significant effects on the customer‐oriented behavior of employees.
Research limitations/implications
The empirical data relevant to the self‐efficacy and organizational climate of this study are acquired transversely and may not actually reflect the experience and perception of interviewees. The results of this empirical study are inferred from questionnaires returned by the sales managers of five life insurance companies. Since the representativeness of the samples is inadequate, the generality, expandability, and persuasiveness of the result need to be enhanced.
Practical implications
This study confirms that internal marketing must be executed successfully to ensure satisfactory performance of external marketing, and the creation of good organizational climate is especially important.
Originality/value
The empirical analysis in this paper reveals that obedience, interpersonal relationships, comity, patience, and being contented are all aspects of value orientation. This paper offers practical help to managers to provide subordinate professional training.

Abstract
Purpose
Previous research is mainly devoted to value connotations obtained from the physical environment, rather than the effect on experience value from the perspective of customers' self‐efficacies and involvement. This paper attempts to combine multivariate statistical analysis and nonlinear fuzzy neural network model for data analysis.
Design/methodology/approach
Convenience sampling was adopted to investigate the employees from dozens of hi‐tech enterprises in the Hsinchu science‐based Industrial Park and Tainan Science‐based Industrial Park.
Findings
Customers' involvement levels have a positive effect on experience value; customers' positive moods have stronger positive effect than negative moods; customers' experience value may vary due to different environmental atmospheres and self‐efficacies.
Research limitations/implications
The investigation for the employees of a hi‐tech industry may deduce different implications due to various parent samples or sampling errors. So, subsequent research may perform a comparison of different regions or industries. Only 179 out of 500 samples are collected in this research. The relatively low‐recovery rate is attributed to the inclusions of numerous items in the questionnaire. This paper discusses transversely the predisposing influential factors of experience value.
Practical implications
The empirical results show that the fuzzy neural network model could measure the relationship of variables more accurately and also eliminate the existing restrictions, making it suitable for social science sectors such as business management.
Originality/value
Previous researches highlight the experience value of playfulness in the tourism industry, but little attention has been paid to the combination of education and playfulness along with self‐efficacy.

Abstract
The set of fuzzy threshold functions is defined to be a fuzzy set over the set of functions. All threshold functions have full memberships in this fuzzy set. Defines and investigates a distance measure between a non‐linearly separable function and the set of all threshold functions. Defines an explicit expression for the membership function of a fuzzy threshold function through the use of this distance measure and finds three upper bounds for this measure. Presents a general method to compute the distance, an algorithm to generate the representation automatically, and a procedure to determine the proper weights and thresholds automatically. Presents the relationships among threshold gate networks, artificial neural networks and fuzzy neural networks. The results may have useful applications in logic design, pattern recognition, fuzzy logic, multi‐objective fuzzy optimization and related areas.

Abstract
Manufacturing is a key to continuous economic growth. Fuzzy expert systems, fuzzy logics, fuzzy languages, fuzzy neural networks, and intelligent control are proposed as additional tools in manufacturing. Fuzzy logic is a new way to program computers and appliances to mimic the imprecise way humans make decisions. Fuzzy logic has been applied to cameras, subways, computers and air conditioners. Through the use of fuzzy logic, fuzzy expert systems can be built which add a new dimension in the technologies for intelligent factories.

Abstract
Purpose
The pre-tender estimation process is still a hazy and inaccurate process, despite it has been practiced over decades, especially in Malaysia. The methods evolved over time largely depend on the amount of information available at the time of estimation. More often than not, the estimate produced during the pre-tender stage is far more than the tender cost of the project and sometimes, it is perilously underestimated and caused major problems to the client in the monetary planning. The purpose of this paper is to determine the most influential factors on the deviation of pre-tender cost estimation in Malaysia by conducting a survey.
Design/methodology/approach
Fuzzy logic, combined with artificial neural network method (fuzzy neural network) was then used to develop an estimating model to aid the pre-tender estimation process.
Findings
The results showed that the model is able to shift the cost estimation toward accuracy. This model can be used to improve the pre-tender estimation accuracy, enabling the client to take the necessary early measures in preparing the funding for a building project in Malaysia.
Originality/value
To the authors’ knowledge, this is the first study on tender price estimation standardization for a construction project in Malaysia. In addition, the authors have used factors from literature for the model, which shows the thoroughness of the developed model. Thus, the findings and the model developed in this study should be able to assist contractors in coming out with a more accurate tender price estimation.

Abstract
Purpose
The purpose of this paper is to develop a methodology for the stochastically asymptotic stability of fuzzy Markovian jumping neural networks with time-varying delay and continuously distributed delay in mean square.
Design/methodology/approach
The authors perform Briat Lemma, multiple integral approach and linear convex combination technique to investigate a class of fuzzy Markovian jumping neural networks with time-varying delay and continuously distributed delay. New sufficient criterion is established by linear matrix inequalities conditions.
Findings
It turns out that the obtained methods are easy to be verified and result in less conservative conditions than the existing literature. Two examples show the effectiveness of the proposed results.
Originality/value
The novelty of the proposed approach lies in establishing a new Wirtinger-based integral inequality and the use of the Lyapunov functional method, Briat Lemma, multiple integral approach and linear convex combination technique for stochastically asymptotic stability of fuzzy Markovian jumping neural networks with time-varying delay and continuously distributed delay in mean square.

Abstract
Purpose
Demand forecasting in the clothing industry is very complex due to the existence of a wide range of product references and the lack of historical sales data. To the authors' knowledge, there is an inadequate number of literature studies to forecast the demand with the adaptive network based fuzzy inference system for the clothing industry. The purpose of this paper is to construct a decision support system for demand forecasting in the clothing industry.
Design/methodology/approach
The adaptive‐network‐based fuzzy inference system (ANFIS) is used for forecasting demand in the clothing industry.
Findings
The results of the proposed study showed that an ANFIS‐based demand forecasting system can help clothing manufacturers to forecast demand more accurately, effectively and simply.
Originality/value
In this study, the demand is forecast in terms of clothing manufacturers by using ANFIS. ANFIS is a new technique for demand forecasting, it combines the learning capability of the neural networks and the generalization capability of the fuzzy logic. The input and output criteria are determined based on clothing manufacturers' requirements and via literature research, and the forecasting horizon is about one month. The study includes the real life application of the proposed system and the proposed system is tested by using real demand values for clothing manufacturers.

Abstract
Purpose
The energy efficiency of buildings has been emphasized along with the continual development in the building and construction sector that consumes a significant amount of energy. To this end, the purpose of this research paper is to forecast energy consumption to improve energy resource planning and management.
Design/methodology/approach
This study proposes the application of the convolutional neural network (CNN) for estimating the electricity consumption in the Grey Nuns building in Canada. The performance of the proposed model is compared against that of long short-term memory (LSTM) and multilayer perceptron (MLP) neural networks. The models are trained and tested using monthly electricity consumption records (i.e. from May 2009 to December 2021) available from Concordia’s facility department. Statistical measures (e.g. determination coefficient [R2], root mean squared error [RMSE], mean absolute error [MAE] and mean absolute percentage error [MAPE]) are used to evaluate the outcomes of models.
Findings
The results reveal that the CNN model outperforms the other model predictions for 6 and 12 months ahead. It enhances the performance metrics reported by the LSTM and MLP models concerning the R2, RMSE, MAE and MAPE by more than 4%, 6%, 42% and 46%, respectively. Therefore, the proposed model uses the available data to predict the electricity consumption for 6 and 12 months ahead. In June and December 2022, the overall electricity consumption is estimated to be 195,312 kWh and 254,737 kWh, respectively.
Originality/value
This study discusses the development of an effective time-series model that can forecast future electricity consumption in a Canadian heritage building. Deep learning techniques are being used for the first time to anticipate the electricity consumption of the Grey Nuns building in Canada. Additionally, it evaluates the effectiveness of deep learning and machine learning methods for predicting electricity consumption using established performance indicators. Recognizing electricity consumption in buildings is beneficial for utility providers, facility managers and end users by improving energy and environmental efficiency.

Abstract
Purpose
This study aims to bring awareness to the developing of fault detection systems using the data collected from sensor devices/physical devices of various systems for predictive maintenance. Opportunities and challenges in developing anomaly detection algorithms for predictive maintenance and unexplored areas in this context are also discussed.
Design/methodology/approach
For conducting a systematic review on the state-of-the-art algorithms in fault detection for predictive maintenance, review papers from the years 2017–2021 available in the Scopus database were selected. A total of 93 papers were chosen. They are classified under electrical and electronics, civil and constructions, automobile, production and mechanical. In addition to this, the paper provides a detailed discussion of various fault-detection algorithms that can be categorised under supervised, semi-supervised, unsupervised learning and traditional statistical method along with an analysis of various forms of anomalies prevalent across different sectors of industry.
Findings
Based on the literature reviewed, seven propositions with a focus on the following areas are presented: need for a uniform framework while scaling the number of sensors; the need for identification of erroneous parameters; why there is a need for new algorithms based on unsupervised and semi-supervised learning; the importance of ensemble learning and data fusion algorithms; the necessity of automatic fault diagnostic systems; concerns about multiple fault detection; and cost-effective fault detection. These propositions shed light on the unsolved issues of predictive maintenance using fault detection algorithms. A novel architecture based on the methodologies and propositions gives more clarity for the reader to further explore in this area.
Originality/value
Papers for this study were selected from the Scopus database for predictive maintenance in the field of fault detection. Review papers published in this area deal only with methods used to detect anomalies, whereas this paper attempts to establish a link between different industrial domains and the methods used in each industry that uses fault detection for predictive maintenance.
