Enhancing accelerometer calibration results by reporting interpolated calibration data

Ian Veldman, Anderson Maina, Henrik Volkers — Tue, 18 Aug 2026 00:00:00 +0000

This paper describes the implementation of interpolation methods (fitting curves) for reporting complex (magnitude and phase) accelerometer calibration measurements. The authors’ evaluation focused on two interpolation methods: polynomial fit and mathematical model description of a charge accelerometer. Charge accelerometers, such as the Brüel & Kjær model 8305 and the ENDEVCO model 2270, are the de facto laboratory standard accelerometers. NMIs have been maintaining sensitivity calibration data, with the associated uncertainty of measurement (UoM), on such devices for decades and reported publicly available comparison data using these accelerometers, which provide ample vetted data for curve-fitting technique investigations.

Assessment of innovation management systems in established innovative companies: A conceptual model based on ISO 56002:2019 standard

Felippe Vicencio Gomes , Maria Fatima Ludovico de Almeida — Tue, 18 Aug 2026 00:00:00 +0000

This study presents a comprehensive assessment model designed to facilitate organizational excellence in innovation management through a systematic evaluation of maturity levels vis-à-vis the ISO 56002:2019 standard clauses and items. The practical applicability of the model was validated through an empirical investigation conducted at Light SESA, a prominent organization in the Brazilian electricity sector. The methodological framework encompasses six interconnected phases: (i) an extensive literature review and documentary analysis of pertinent research domains; (ii) development of an analytical framework based on ISO 56002:2019 parameters; (iii) implementation of the Analytic Network Process (ANP) for weight attribution to dimensional and factorial components within the assessment structure; (iv) design and validation of a survey instrument targeting senior leadership and RD&I project managers to evaluate organizational maturity relative to ISO 56002:2019 requirements; (v) application of fuzzy logic principles for processing collective judgments, thereby mitigating assessment bias; and (vi) utilization of Importance-Performance Analysis (IPA) methodology to identify priority areas for innovation management system enhancement. The primary contribution of this research is a robust, empirically validated model for assessing innovation management system maturity in organizations seeking to enhance their innovative capabilities and performance metrics.

Self-assessment model for pharmaceutical companies based on Good Manufacturing Practices for pharmaceuticals in Brazil: a multicriteria approach

Alexandre Nunes, Maria Fatima Ludovico de Almeida, Daniel Lousada — Tue, 18 Aug 2026 00:00:00 +0000

This study presents a novel self-assessment model for evaluating organizational compliance capabilities within Brazilian pharmaceutical companies regarding the Resolution RDC 658/2022 requirements established by the National Health Surveillance Agency (Anvisa) aligned with the World Health Organization's Good Manufacturing Practices (GMP) for pharmaceutical products. The research methodology comprised a systematic literature review and documentary analysis spanning 2010-2023, followed by the development of an analytical framework integrating the Analytic Hierarchy Process (AHP) for weighting the regulatory requirements of the aforementioned Resolution. The model's empirical validation was conducted through implementation at a Brazilian pharmaceutical company, evaluating its organizational compliance capabilities vis-à-vis the RDC 658/2022 requirements. Importance-Performance Analysis (IPA) was subsequently employed to prioritize areas that require enhanced regulatory compliance. The primary contribution of this study is a comprehensive self-assessment framework that provides pharmaceutical companies with robust decision-making support for visa certification processes. Empirical validation demonstrated the model's effectiveness in identifying critical compliance gaps and prioritizing improvement initiatives. This methodological advancement strengthens the interface between health regulatory authorities and pharmaceutical companies, potentially enhancing the effectiveness of Brazil’s regulatory system

Multicriteria conceptual framework for maturity assessment of testing and calibration laboratories based on the ISO/IEC 17025: 2017 standard

David Correa , Maria Fatima Ludovico de Almeida — Tue, 18 Aug 2026 00:00:00 +0000

This study presents a novel multicriteria framework for assessing the maturity of testing and calibration laboratories in accordance with ISO/IEC 17025:2017 requirements. The research methodology comprised a systematic literature review spanning 2010–2023, followed by the development of an analytical framework integrating the Analytical Hierarchy Process (AHP) for weighting standard requirements and the Importance–Performance Analysis (IPA) for maturity assessment. The framework's empirical validation was conducted at the Brazilian Army Evaluation Center (CAEx) to evaluate laboratory compliance capabilities vis-à-vis the ISO/IEC 17025:2017 requirements regarding competence, impartiality, and operational consistency. The validation process involved senior laboratory managers and resulted in quantitative maturity assessments across standard requirements, enabling the identification of critical improvement areas and the development of targeted action plans for accreditation preparation. The primary contribution of this study is a comprehensive assessment framework that provides testing and calibration laboratories with robust decision-making support for accreditation processes. The empirical validation demonstrated the effectiveness of the framework in identifying critical compliance gaps and prioritizing improvement initiatives. This methodological advancement is a significant contribution to the field of laboratory quality management.
