In a globalized world, the banking sector has been forced to advance not only in financial performance, but also in non-financial performance, especially in sustainability criteria. For this purpose, multicriteria decision methods are especially suited to evaluate efficiency and to make a stable ranking of the most outstanding banks in the Spanish financial system. However, we are aware of the difficulties involved due to the inherent uncertainty and subjectivity of this process. For this reason, the use of fuzzy models is proposed, especially intuitionistic fuzzy numbers combined with the Analytic Hierarchy Process and the TOPSIS. The combination of financial criteria based on the CAMELS rating system with non-financial sustainability criteria makes it possible to order the Spanish banking system based on global efficiency. The most relevant contributions are: first, the use of intuitionistic fuzzy numbers in the performance evaluation process, whereby the quality of the information available can be quantified; and the most important one, a simplification of the process in the implementation of the intuitionistic fuzzy TOPSIS. Finally, through a sensibility analysis, it is possible to isolate the relevance of the sustainability process to obtain the global performance evaluation.

The use of mulching in agriculture suppresses the weeds around crop plants, enhances the nutrients status of soil, controls the soil structure and temperature, and reduces soil water evaporation. Excessive use of low-density polyethylene mulches is contributing to the accumulation of high amounts of plastic wastes, an environmental problem for agricultural ecosystems. Fragments of plastic from such wastes can be found in soils, in water resources, and in organisms, including humans. The objective of this work was to study the economic viability of the use of different hydromulches in an artichoke crop. Three blends were prepared by mixing paper pulp (recycled from used paper) and cardboard (from paper mills) with different additives: wheat straw (WS), rice hulls (RH), and substrate used for mushroom cultivation (MS). These were compared with low-density polyethylene (Pe), a treatment without mulching on bare soil where hand weeding was performed (HW), and a treatment without mulching on bare soil where herbicide was applied (H). The results indicate that the use of hydromulch in an artichoke crop represents a good alternative for reducing plastic waste in agriculture. The net profits of the hydromulch treatments (MS, WS, RH) were higher than for HW and H, and slightly lower than for Pe. The most profitable treatment was Pe (€0.69 m−3), followed by RH (€0.59 m−3), WS (€0.58 m−3), MS (€0.47 m−3), HW (€0.36 m−3), and H (€0.32 m−3). A sensitivity analysis showed a probability of negative results of 0.04 in Pe, 0.13 in SM, 0.08 in WS, and 0.07 in RH, so the probability that the grower will make a profit is greater than 0.9 with the use of mulch (except mushroom substrate) or polyethylene.

Apart from the effects of treating those infected with COVID-19, the pandemic has also affected treatment for other diseases, which has been either interrupted or canceled. The aim of this paper is to provide a financial model for obtaining the cost overrun resulting from the worsening of illnesses and deaths for each of the causes considered. To achieve this, first deaths have been classified into causes of death and for each of these causes, an estimation has been made of the worsening condition of patients due to delay in treatment. Through these data, a fuzzy relation between deaths and the worsening condition of patients can be obtained. Next, the expertise process has been used to estimate cost overrun in relation to patients’ pathologies. The experts’ opinions have been aggregated using ordered weighted average (OWA). Lastly, using fuzzy logic again, a correction coefficient has been determined, which optimizes the future implementation of the proposed model without the need for a new estimation of inputs. The paper concludes with a numerical example for a better comprehension of the proposed theoretical model. Ultimately, it provides the scientific community in general and in particular managers of public administration entities with a novel tool for improving the efficiency of the healthcare system.

Greenhouse peppers are one of the most important crops globally. However, as in any production activity, especially agricultural, they are subject to important risk factors such as price fluctuations, pests, or the use of bad quality water. This article aims to evaluate the viability of these types of crops by using discounted cash flows. Risk evaluation has been carried out through the analysis of pepper plantations for 2016 and 2017. The traditional application of this tool has significant limitations, such as the discount rate to be used or the estimation of future cash flows. However, by using discount functions that decrease over time in combination with decoupled net present value, these limitations are expected to improve. The use of decoupled net present value has permitted an increase in the accuracy and quantification of risks, isolating the main risks such as price drops (EUR 3720 ha−1 year−1) and structural risks (EUR 1622 € ha−1 year−1). The use of decreasing discount functions has permitted a more realistic investment estimation. Finally, the sensitivity analysis shows that decoupled net present value (DNPV) is little affected by changes in interest rates in contrast to traditional net present value (NPV).

The relation between corporate social responsibility (CSR) and financial performance (FP) has been widely dealt with in specialized literature. This study has two points of interest: first, we develop a new tool which financially quantifies the value contributed to companies that are committed to CSR; then, we make a practical application of this tool through an empirical study focused on Spanish companies. This study is especially innovative because of the fuzzy methodology used and the way it defines CSR through the IQNet SR10 certification of social responsibility systems. In addition, the measurement of CSR through IQNet SR10 certification is a completely new approach to the subject. An interesting conclusion can be drawn from the empirical study: IQNet SR10 CSR certification increases the value of businesses. However, neither size nor the economic sector they belong to influence this relationship significantly.

BACKROUND The current need to produce food for a growing population starting with natural resources per inhabitant that are diminishing, such as water and energy, and with minimum environmental degradation, demands the optimization of production. In this work we establish and compare the economic feasibility of tomato production in an open system with a perlite substrate, a closed system with the Nutrient Film Technique (NFT) and a hydroponic crop (Deep Flow Technique, DFT) utilizing three levels of salinity that are found within the normal range for irrigation water quality in Southeastern Spain. RESULTS The production with DFT resulted in an increase of the cost of the phytosanitary treatments and cost of maintenance. The production with perlite resulted in an increase in the cost of irrigation water and fertilization, and the use of NFT resulted in an increase in energy cost. The point of price equilibrium, as well as production were exceeded in the three soilless systems when using low salinity water, and in perlite, with intermediate salinity water. CONCLUSION The profitability of the exploitation was reduced in the order perlite>NFT>DFT and had positive results when using irrigation water with low salinity, and in the case of perlite, with intermediate salinity. In every case, the salinity reduced the profitability of the operation, and this was greater when NFT was employed. The analysis of these soilless systems should be continued in order to determine the possibility of reducing the cultivation costs. This article is protected by copyright. All rights reserved.

This research aims to develop a model that is able to integrate and objectify information provided by the different business valuation methods, incorporating quality management in its formal approach, which to date has not been considered in the literature about business valuation or quality management. Firstly, the company is valued using the methods which best adapt to its specific characteristics. Because of the subjectivity inherent in any valuation process, the results will be expressed through Triangular Fuzzy Numbers (TFN). These Fuzzy Numbers will be aggregated and summarized by applying Basic Defuzzification Distribution Uncertain Probabilistic Ordered Weighted Averaging operator (BADD-UPOWA). The weighting factors will be: the degree of confidence in each of the business valuation methods applied, and the innovative use of the company’s position on Crosby’s Quality Administration Grid. The results from application of the model in a case study show a significant reduction in uncertainty in contrast to the initial valuations. Moreover, the proposed methodology is seen to increase the final value of the company as its advances in quality management.

In the present work, the coordinates L*, a* and b* from the CIELAB color space, as well as the chlorophyll, total carotenoids and the content of the carotenoids Lutein and β-cryptoxanthin were measured in the skin of fruits from the Fino 49 lemon during its development, with the aim of understanding the relationship that exists between the color changes of the fruit’s skin (color coordinates) and the pigment content. Also, the understanding of the relative importance of the contents of lutein and β-cryptoxanthin with respect to the total content of carotenoids was sought. The period of study lasted three years; from September 2015 to January 2016, from September 2016 to January 2017, and from September 2017 to January 2018, the periods that comprised the color changes of the lemon fruit until its harvest. The fruits were measured every two weeks in the experimental plot of the IMIDA (Murcian Institute of Agricultural and Food Research and Development) located at La Alberca (Murcia, Spain) and in the experimental orchards from the CEBAS-CSIC, located in Santomera (Murcia). During the experiment, the color and chlorophyll, Lutein and β-cryptoxanthin concentrations were measured. The results showed that there was a good correlation between the color coordinates and the pigments responsible for the lemon’s skin color: all the color pigments were correlated with the a*, b* color coordinates and the Hue angle index. Throughout the fruit’s maturation, a degradation of the chlorophylls was observed, as well as an increase of β-cryptoxanthin, which is responsible for the green and yellow color of the fruits, respectively. Lutein, which was found in high concentrations, decreased with time, but did not contribute to the fruit’s color.

Several hypotheses regarding hand and mechanical harvesting have been analysed, in order to estimate the economic possibilities for the mechanical harvesting of lemons taking into account the current availability of technology. We considered several detachment options under experimental conditions; only yellow detachment has been considered for mechanical harvesting, because the sensitivity to the impacts is lower and mechanical detachment was high (80%). Price changes throughout the season were also considered. Total harvest cost is an average of the cost of mechanical harvesting (80%) and the cost of manually harvesting remaining fruit (20%), plus the cost of handling the mechanical harvested fraction. This cost ranges between 0.031 € kg−1 and 0.058 € kg−1 for outputs between 20 t ha−1 and 60 t ha−1, respectively, which is always lower than harvesting by hand (0.065 € kg−1). A Monte Carlo approach was used to study the sensitivity of the results, and value at risk (VaR) was calculated. The analysis showed that the mechanical harvesting margin is 0.020 € kg−1 higher than the hand harvesting margin and the output dispersion is higher in March. The VaR analysis showed that at 10%, there was no risk that the hand margin is higher than the mechanical margin and at 5%, the risk is very low and only for March harvesting. Mechanical harvesting represents a good economic option compared to hand harvesting, since it can increase farmer income by between 400 € ha−1and 1200 € ha−1.

Purpose The economic effects resulting from the commitment to ISO 9001 certification is a controversial issue. Many authors have concluded about the positive economic effects resulting from the establishment of quality systems in accordance with the requirements established in the ISO 9001 standard, but other authors have not appreciated this positive relationship. The purpose of this paper is to provide a model that facilitates the valuation of the ISO 9001 quality system. Design/methodology/approach In the process of developing a valuation model, given the uncertainty this process involves, the use of fuzzy math is very useful. First, as for an internal valuation method, the authors highlight the discounted cash flow in a fuzzy environment. The internal valuation will be completed by external expert opinions. To improve the information supplied by experts, the paper makes use of the experton theory. In this context, the authors propose the aggregation of the experts’ opinion by using basic defuzzification distribution (BADD)-fuzzy induced ordered weighted averaging. Finally, the results undergo contra-expertise. After presenting the theoretical model, the authors proceed with its application by using a case study. Findings The paper develops a new method for the economic evaluation of the ISO 9001 certification. Originality/value The authors propose the valuation of ISO 9001 quality management system, and they do it using some interesting tools which fuzzy logic offers. In this way, it is possible to eliminate subjectivity and improve the final results.

Despite the difficulty in measuring hidden quality costs, we must be aware not only of their existence, but also of their importance. Not surprisingly, they have been the causative factor in the closure of many companies because they are doubly dangerous. One the one hand, they represent very significant quantities of money and, on the other, they remain hidden, like the submerged portion of an iceberg [Campanella, J. (1999). Principles of Quality Costs: Principles, Implementation and Use. Milwaukee, WI: ASQ Quality Press]. Possibly one of the most harmful hidden quality costs, and most difficult to quantify, is the cost of loss of image (CLI) a company suffers because of faults detected by its customers. This paper develops an original tool that, with the use of fuzzy logic as an alternative to probabilistic theory, is capable of facilitating the quantification of the CLI in any company from the observation of its customer complaints. Once the theoretical model is presented, we proceed with its experimentation, making use of a case study as research methodology.

While most of lemon cultivars in the northern hemisphere are harvested in autumn-winter, Verna, an autochthonous Spanish cultivar, is harvested later (February to August), supplying the European market when lemons are in short supply, a market that is also served by imports from the southern hemisphere, mainly Argentina and South Africa. The aim of this study was to determine the temperature at which degreening begins naturally in Verna lemon, noting the evolution of colorimetric parameter a and comparing the same with the equivalent measurements made in Eureka lemon, the most widely cultivated lemon worldwide. The influence of solar radiation on the colorimetric parameters was studied, and then the influence of the minimum temperatures on the change from green to yellow, using the data collected over five growing seasons, was also assessed. The results confirmed the relation between net solar radiation and degreening in Verna, a process that begins when net solar radiation reaches a value of between 2 and 4 MJ/m2.day and when the mean temperature of the 14 days prior to sampling is8.8 ºC or when the daily mean temperature reaches5.5 ºC on two consecutive days. The information obtained will enable growers to predict the colour changes that will occur in the field and potential growers to ascertain whether a given geographical zone is suitable for the crop in question.
