Abstract

Purpose

This study proposes a systematic and comprehensive circular economy (CE) performance measure as an instrument to operationalize and quantify circularity. It seeks to evaluate the relative contribution of blockchain technology to evaluate various measures in this study. A general research agenda for investigating blockchain capabilities to performance assessment in CE is presented.

Design/methodology/approach

Empirical survey data from 32 CE and blockchain experts are collected to inform this study. Inductive reasoning, heatmaps, and a middle-range theory building approach are utilized to generalize theoretical patterns for blockchain support of CE performance assessment and measurement. A series of propositions are then developed as a middle-range theory for the true, false, perceptible, and hidden affordances of blockchain technology capabilities for CE performance measurement.

Findings

Overall, sixteen performance measures and metrics are identified and examined. The authors find most of these measures and metrics – based on literature and expert opinion – can be supported using blockchain technology capabilities. Four major blockchain capabilities, transparency and traceability, reliability and security, smart contracts, and incentivization and tokenization are shown to have varying potential support for CE performance assessment. There needs to be an evaluation of true, false, perceptible, and hidden affordances of blockchain technology capabilities for CE performance measurement in future studies.

Originality/value

Blockchain application for CE, and specifically performance measurements, is a new area. Research and practice evaluation on this issue is important but needs substantially additional investigation to help CE progress. This study provides a framework for evaluation and a foundation for future research at the nexus of CE, blockchain technology, and performance measurement.

Abstract

Purpose

The aim of this study is to empirically explore and analyze the concrete tasks of output measurement and the inherent challenges related to these tasks in a traditional and autonomous professional public work setting – the judicial system.

Design/methodology/approach

The analysis of the tasks is based on a categorization of general performance measurement motives (control-motivate-learn) and main stakeholder levels (society-organization-professionals). The analysis is exploratory and conducted as an empirical content analysis on materials and reports produced in two performance improvement projects conducted in European justice organizations.

Findings

The identified main tasks in the different categories are related to managing resources, controlling performance deviations, and encouraging improvement and development of performance. Based on the results, key improvement areas connected to output measurement in professional public organizations are connected to the improvement of objectivity and fairness in budgeting and work allocation practices, improvement of output measures' versatility and informativeness to highlight motivational and learning purposes, improvement of professional self-management in setting output targets and producing outputs, as well as improvement of organizational learning from the output measurement.

Practical implications

The paper presents empirically founded practical examples of challenges and improvement opportunities related to the tasks of output measurement in professional public organization.

Originality/value

This paper fulfils an identified need to study how general performance management motives realize as concrete tasks of output measurement in justice organizations.

Abstract

Recently, gauge repeatability and reproducibility (GR&R) study has been highly regarded by the quality practitioners when QS9000 and D19000 become fashionable requirements for manufacturing industries. Measurement plays a significant role in helping organizations improve their product quality. Good quality of products is the key factor towards business success. Therefore, how to ensure the quality of measurement becomes an important task for quality practitioners. In performing the GR&R study, several parameters, such as the appropriate sample size of parts (n), number of inspectors (p) and replicate measurements (k) are frequently asked by quality personnel in industries. The adequacy of current way of (n, p, k) selection is very questionable. A statistical method using the shortest confidence interval and its associated computer programming algorithm are presented in this paper for evaluating the optimal allocation among sample size of parts (n), number of inspectors (p) and replicate measurements (k). Hopefully, it can provide a useful reference for quality practitioners in industries.

Abstract

Purpose

The purpose of this paper is to demonstrate how a systems approach can be used to facilitate the development of an organizational performance measurement system.

Design/methodology/approach

Based on a review of the literature, the paper introduces the implications for applying a systems approach to organizational performance measurement. To demonstrate the transition from theory to practice, a case study is provided to show how a sustainable development performance measurement system was developed at a Canadian electric utility. The case study involved extensive consultation with over 25 experts.

Findings

The paper finds that a systems approach is useful in developing the process and that a set of formal systems criteria is useful in developing the structure and content of a performance measurement system. These concepts are highlighted throughout the case study example.

Research limitations/implications

The case study section was based on findings from a single organization. Further work is required to validate the findings within other organizations.

Practical implications

The paper shows how a robust sustainable development performance measurement system may be developed at an electric utility. The overarching emphasis on integration of the system with the case utility's mainstream initiatives demonstrates that a performance measurement system must build on what the organization already has in place. The systems‐based approach and formal systems criteria used in the paper may be transferable to other organizations.

Originality/value

The paper shows that a systems approach provides both the structure and flexibility needed to guide the design, implementation, and evolution of a sustainable development performance measurement system within existing organizational infrastructure.

Abstract

Draws a comparison between the use of a genetic algorithm and the sequential function specification method for the solution of a one‐dimensional linear inverse thermal field problem, based on the use of noisy measurements. In solving this problem aims to estimate the value of a single constant convective heat transfer coefficient. Documents the findings that both approaches can provide estimates within 1 per cent of the target solution and that the sensitivity and robustness of each approach to measurement location, time step size and measurement errors are markedly different.

Abstract

Purpose

The purpose of this paper is to examine how different network members utilize and use network‐level performance measurement information. This is an important approach when discussing the management and development of a network by utilizing a performance measurement system.

Design/methodology/approach

The study is a single‐case study, where a collaborative network forms the case. The data of the study have been gathered from an action research process of network performance measurement system design and its implementation phase in 2009, interviews in 2010, and discussions with the interviewees in 2012 to re‐evaluate the results.

Findings

The results of the study reveal that the use of the network‐level performance measurement system increased communication, trust, and commitment in the whole network, as well as in a single reselling unit. The performance measurement information also helped the companies create better alignment with their network partners.

Practical implications

The paper presents the main uses, utilizations and benefits of network‐level performance measurement and management from the perspectives of the different network members.

Originality/value

The case study contributes to the literature of performance measurement and management in a network environment. It presents the main uses and utilization of network‐level performance management and measurement.

Abstract

Describes research designed to examine the effects of subject positioning on the accuracy of body scan data. A body measurement system developed by the Textile Clothing Technology Corporation was used to acquire two scans from each of 72 subjects. The subjects were instructed to continue to breathe normally and stand with their feet shoulder‐width apart. The two scans were compared and statistical analysis was performed to determine the precision of the results and whether this lack of standardization affected the data. Physical measurements were also obtained from each subject and served as a basis for comparison to the scanned measurements. Since physical measurements are the current accepted “true value”, these measurements determined the level of accuracy of scanned data. Three separate scans of 72 different subjects were taken at various levels of breathing and at various foot positions to determine the effect of the variables. This study certainly indicates that respiration and foot placement has a significant effect on body scan data. It was established that the scan data rendered by the software does have precision, but lacks accuracy when compared against physical measurements. This may be owing to the inaccuracies of the physical measurement process or to differences in measurement location between the anthropometrist and the 3D measurement extraction software. Information detailing the level of accuracy and precision that can be obtained with scanning software and how respiration and subject positioning can affect the data are included.

Abstract

Purpose

Significant research has been carried out in terms of development of new bidirectional reflectance distribution function (BRDF) instruments; however, there is still little research available regarding spectral BRDF measurements of human skin. This study aims to investigate the variation in human skin reflectance using a new fibre optic-based spectral-BRDF measurement device.

Design/methodology/approach

Design of this system mainly involves use of multiple fibre optics to illuminate and detect light reflected from a sample, whereas a hemispherical dome was 3D printed to mount the fibres at various slant/tilt angles. To investigate the spectral differences in BRDF of human skin, 3 narrowband filters in the visible spectrum were used, whereas measurements were taken from the back of the hand for Caucasian and Asian skin types.

Findings

The experiments demonstrate that the BRDF of human skin varies with wavelengths in the visible spectrum and it is also different for Caucasian and Asian skin types. Both skin types exhibit off-specular reflection with increase in angle of incidence and show less variation with respect to viewing angles when the angle of incidence is normal to the surface.

Research implications

A database of spectral BRDF measurements of human skin will help not only in creating realistic skin renderings but also in development of novel skin reflectance models for biomedical and machine vision applications. The measurements would also provide means to validate the predictions from existing light transport/spectral simulation models for human skin and will ultimately help in the accurate diagnosis and simulation of various skin disorders.

Originality/value

The proposed system provides fast scatter measurements by utilising multiple fibres to detect light simultaneously at different angles while also allowing easy switching between incident light directions. Due to its flexible design and contact-based measurements, the device is independent of errors due to sample movements and does not require any image registration. Also, measurements taken from the device show that the BRDF of skin varies significantly in the visible spectrum and it is different for Caucasian and Asian skin types.

Abstract

Seam pucker is one of the most important aspects of garment quality in the sewing process. Recently, automatic sewing systems have been developed and seam pucker or other defects would have to be automatically inspected in these systems. Two systems of automatic, contactless measurement of seam pucker have been developed. One of the measurement systems, with which surface shape of seam pucker was measured, is based on laser technology. Intensity of reflected ultrasonic wave is measured using another measurement system. The laser measurement system has been applied to moderate or severe seam pucker and the ultrasonic wave system has been applied to the accurate evaluation of very small seam pucker. The result of the evaluation by machine has to match the result of subjective evaluation by humans. To verify this, samples of seam pucker were evaluated using five judges. With the measurement data of surface shape of these samples, the power spectra of the wave form of seam pucker are calculated. Analyses and correlates the relationship between objective measurement and subjective evaluation by discriminant analysis, with the result of subjective evaluation and the power spectra of the samples. Having obtained these relationships, the degree of seam pucker can be measured objectively by both systems.
