The purposes of this research are to study the theory and method of multi-attribute index system design and establish a set of systematic, standardized, scientific index systems for the design optimization and inspection process. The research may form the basis for a rational, comprehensive evaluation and provide the most effective way of improving the quality of management decision-making. It is of practical significance to improve the rationality and reliability of the index system and provide standardized, scientific reference standards and theoretical guidance for the design and construction of the index system.

Using modern methods such as complex networks and machine learning, a system for the quality diagnosis of index data and the classification and stratification of index systems is designed. This guarantees the quality of the index data, realizes the scientific classification and stratification of the index system, reduces the subjectivity and randomness of the design of the index system, enhances its objectivity and rationality and lays a solid foundation for the optimal design of the index system.

Based on the ideas of statistics, system theory, machine learning and data mining, the focus in the present research is on “data quality diagnosis” and “index classification and stratification” and clarifying the classification standards and data quality characteristics of index data; a data-quality diagnosis system of “data review – data cleaning – data conversion – data inspection” is established. Using a decision tree, explanatory structural model, cluster analysis, K-means clustering and other methods, classification and hierarchical method system of indicators is designed to reduce the redundancy of indicator data and improve the quality of the data used. Finally, the scientific and standardized classification and hierarchical design of the index system can be realized.

The innovative contributions and research value of the paper are reflected in three aspects. First, a method system for index data quality diagnosis is designed, and multi-source data fusion technology is adopted to ensure the quality of multi-source, heterogeneous and mixed-frequency data of the index system. The second is to design a systematic quality-inspection process for missing data based on the systematic thinking of the whole and the individual. Aiming at the accuracy, reliability, and feasibility of the patched data, a quality-inspection method of patched data based on inversion thought and a unified representation method of data fusion based on a tensor model are proposed. The third is to use the modern method of unsupervised learning to classify and stratify the index system, which reduces the subjectivity and randomness of the design of the index system and enhances its objectivity and rationality.

This study used the literature review and the modified Delphi method to evaluate the importance of the catering quality indices of university canteens in China. In order to compile the catering quality indices of university canteens in China as reference for the subsequent improvement of Chinese canteens.

This study first analysed literature data to establish the preliminary quality indices and used the modified Delphi method for measurement. After three rounds of Delphi analysis by 35 experts, the results of the catering quality indices of university canteens in China are summarised.

The research results show that university canteen catering quality issues are divided into six dimensions, including catering safety management, employee hygiene management, catering service, food quality, environmental atmosphere and corporate social responsibility. Catering safety management is the most important index, followed by employee hygiene management.

The research results can be used as suggestions for follow-up improvements in the quality of university canteens in China and a basis of reference for amendments to relevant national or local laws and regulations. The food prices, food quality and whether food hygiene and safety standards are met by university canteens are all related to the health and vital interests of the teachers and students, as well as the stability of the university. Therefore, the government should increase supervision in these aspects to avoid decline in the quality of meals due to low profits and enforce strict requirements for food safety.

The process capability indices have been widely used to measure process capability and performance. In this paper, we proposed a new process capability index which is based on an actual dollar loss by defects. The new index is similar to the Taguchi’s loss function and fully incorporates the distribution of quality attribute in a process. The strength of the index is to apply itself to non‐normal or asymmetric distributions. Numerical examples were presented to show superiority of the new index against Cp, Cpk, and Cpm which are the most widely used process capability indices.

The purpose of this research objective was to analyse social reporting within MERCO Business companies both from the point of view of the quantity of information disclosed and the references about their quality. This approach constitutes a novelty with respect to previous literature on the subject.

This paper assesses how social reporting is being carried out by the companies included in the MERCO Corporate Reputation Business Monitor, MERCO Business, during the period 2014–2016. The methodological design include the construction of a weighted index based on two unweighted indexes related to the quantity revealed and the quality detected. In addition, this study integrates intellectual capital and social responsibility approaches in order to deep into these voluntary disclosures.

While social reporting is considerable from a quantitative point of view within MERCO Business companies, they do not reach very high levels of quality, which is good to counteract the final value of the quantity–quality index that the authors' propose.

In MERCO Business companies, quantity is not a proxy for quality within social reporting. In this sense, only considering both dimensions it will be possible to assess these disclosures in a more complete way.

This study allows a more accurate and comparable view of social reporting than those studies that only focus on how much information is disclosed. Besides, it involves an important advance in the identification of the relative quality of social reporting, opening a new line of research that will be key to comparing this type of disclosures in a more homogeneous way. Likewise, the results can be applied in future studies in the intellectual capital field given the complementarity between both types of disclosures.

Likewise, these results will be of interest for future actions aimed at regulating the improvement of the quality of social reporting in the hands of managers, investors and regulators.

The authors have tested the value of quality in social reporting using a weighted index amongst the most reputable companies in the Spanish scenario. These disclosures have been compared with and without the use of it in order to deduce its value to obtain valid conclusions about social reporting.

The purpose of this paper is to propose an integrated earned value management (EVM) approach to control quality, cost, schedule and risk of projects.

This study represents a new EVM framework by considering a quality control index. Particularly, some control indices and cumulative buffers are defined by two proposed, methods, namely the linear- and Taguchi-based methods. These methods are implemented in three different projects in different industries.

According to the results, integration of the quality index creates a better control situation by providing more accurate information. Hence, project managers could comprehensively monitor the status of important factors to make more precise decisions while maintaining the simplicity of their analysis.

From the methodological and theoretical features, this paper offers new visions because, to the best of authors’ knowledge, no comparable study has been conducted before.

Nursing facility inspections routinely produce statistics revealing sharp disparities in care at both the facility and the state level. But whether high rates of deficiencies are more indicative of stringent enforcement of standards, leading to improved care, or ongoing poor quality care remains unclear. Until this question is answered, families of nursing facility residents, responsible public officials and interested professionals, are all unable to make sound decisions about long-term care quality. We employ cross-sectional, panel data to compare states on multiple indices of both care quality and enforcement stringency. We use the multi-method-multi-trait approach to distinguish these concepts. We find that low rates of deficiencies are positively associated with independent measures of high quality care. But, a prominent nursing facility enforcement index likely registers poor quality care more than stringency of enforcement since it is associated positively with independent indices of poor quality care and negatively with independent measures of enforcement. Attentive publics can have reasonable confidence that low rates of deficiencies indicate high quality care. High rates tend to reflect glaring deterioration in care quality. They are less signals of stringent enforcement than of obviously poor care which prompts more visible enforcement activities. Sadly, there is little evidence suggesting that these enforcement measures improve state-level care quality and thus reduce cross-state disparities in the quality of nursing facility long-term care. However, at least some of the factors responsible for sharp disparities in nursing facility care lie within the capacity of states to rectify even in the short term.

The purpose of this research is to provide a framework in which new data quality dimensions are defined. The new dimensions provide new metrics for the assessment of lecture video indexing. As lecture video indexing involves various steps, the proposed framework containing new dimensions, introduces new integrated approach for evaluating an indexing method or algorithm from the beginning to the end.

The emphasis in this study is on the fifth step of design science research methodology (DSRM), known as evaluation. That is, the methods that are developed in the field of lecture video indexing as an artifact, should be evaluated from different aspects. In this research, nine dimensions of data quality including accuracy, value-added, relevancy, completeness, appropriate amount of data, concise, consistency, interpretability and accessibility have been redefined based on previous studies and nominal group technique (NGT).

The proposed dimensions are implemented as new metrics to evaluate a newly developed lecture video indexing algorithm, LVTIA and numerical values have been obtained based on the proposed definitions for each dimension. In addition, the new dimensions are compared with each other in terms of various aspects. The comparison shows that each dimension that is used for assessing lecture video indexing, is able to reflect a different weakness or strength of an indexing method or algorithm.

Despite development of different methods for indexing lecture videos, the issue of data quality and its various dimensions have not been studied. Since data with low quality can affect the process of scientific lecture video indexing, the issue of data quality in this process requires special attention.

The main purpose of this research was to develop a universal model to evaluate the perceived value of tourism services and satisfaction with, and loyalty to, destinations from the consumers’ perspective and demonstrated the model’s applicability in this context.

Using the structural equation model, cause and effect relationships were identified between the proposed model’s constructs, and indices of quality, satisfaction and loyalty among tourists were estimated. This system was applied to a large set of data collected with a structured questionnaire distributed to tourists visiting the city of Seville through a non-probabilistic sampling by intentional quotas method. In total, 922 valid surveys were obtained.

The indices show that tourists who visit Seville report a high level of loyalty to, and satisfaction with, this place because of the perceived quality of a variety of services. It is observed that the perceived quality index is much higher (17.95 per cent) than the expected quality index, so the quality of the service received by the tourist during his/her visit to Seville is described as excellent.

Regarding this study’s limitations, other variables could have been included that influence tourist satisfaction, such as the climate, the effect of advertising medium, the prices and the emotional components. In addition, surveying tourists’ expectations before their visit is virtually impossible, as is surveying the same tourists again about their perceived value and satisfaction after their visit. Future lines of research could focus on the intersection of information between tourism offer and demand, providing information about an appropriate balance in specific markets. The proposed model can also be applied to other tourism places that are similar to Seville’s tourism offer, allowing useful comparisons and identification of critical points and ways to improve customer satisfaction continuously.

By establishing indices of expected and perceived quality and satisfaction and loyalty among tourists, tourism authorities and different economic agents involved in this sector can receive objective information about the results and quality of tourism services. Tourism managers, thus, can set objectives for improvements and competitiveness, as well as building and maintaining customer loyalty. At the same time, these indices allow comparisons with other organisations and places. By facilitating greater transparency in the measurement of quality and satisfaction, service providers connected to tourism can create a platform on which to articulate clearly their contributions to interested parties and local communities.

These results constitute strategies and findings that any tourism place has to consider in the planning and development of its products. Therefore the model can help to encourage a long-term market perspective among tourism sector regulators, investors and agencies. With the information obtained with this model, areas needing improvement can be identified and the appropriate procedures can be put into practice to improve the tourism offer, adjusting it to meet travellers’ needs according to their motivations to travel to the destination. Residents also can benefit from these measures, as their quality of life will improve through upgrades of the city’s tourism facilities.

The unique contribution of the present study lies in how the indices or indicators of quality of, satisfaction with and loyalty to destinations among tourists are easily measured by applying structural equation modelling. A new approach to measure satisfaction, loyalty and quality is used based on a scale from 0 to 100, and the index results are very useful for comparing different tourist places.

This paper seeks to model and compute productivity, including a measure of quality, of a service which does not have marketable outputs – namely public education at the micro level. This application is a case study for Sweden public schools.

A Malmquist productivity index is employed which allows for multiple outputs or outcomes such as test results and promotions without requiring price data with which to aggregate these outputs. It also allows one to account for inputs such as teachers and facilities as well as proxies for quality of the inputs (e.g. experience of teachers) and outputs. This model generalizes the basic data envelopment analysis (DEA) models – used successfully to measure performance in many educational applications – to the intertemporal case. A way of computing quality and quantity components of overall productivity is employed.

The case study is an application to the Swedish primary and secondary school system over the 1992 to 1995 period. It was found that quality “matters”, i.e. productivity growth changes when one accounts for quantity.

The data available implied that the specification is restricted to an intermediate production model, i.e. the output data only account for the intermediate outcomes of education like grades and promotions, but not the longer term outcomes related to success in the job market or higher education, which one proposed as a task for future research.

The indices which are computed at the micro level are of value for policy purposes (does investment in quality matter?) and in an evaluation context.

This study aims to show how hedonic methods can be used to compare the performance of the public and private sector housing markets in Costa Rica.

Hedonic price indexes are computed using the adjacent-period method. Average housing quality is measured by comparing hedonic and median price indexes. The relative performance of the public and private sector residential construction is compared by estimating separate hedonic models for each sector. A private sector price is then imputed for each house built in the public sector, and a public sector price is imputed for each house built in the private sector.

The real quality-adjusted price of private housing rose by 12 per cent between 2000 and 2013, whereas the price of private housing rose by 9 per cent. The average quality of private housing rose by 45 per cent, whereas that of public housing fell by 18 per cent. Nevertheless, the hedonic imputation analysis reveals that public housing could not be produced more cheaply in the private sector.

The quality of public housing has declined over time. The hedonic analysis shows that the decline is not because of a lack of competition between construction firms in the public sector. An alternative demand side explanation is provided.

This study applies hedonic methods in novel ways to compare the relative performance of the public and private housing sectors in Costa Rica. The results shed new light on the effectiveness of public sector housing programs.
