“…Using neuronavigation transcranial magnetic stimulation (nTMS) measures of cortical excitability, inhibition, and facilitation in the primary motor cortex, Therrien-Blanchet et al (2022) [10] sought to determine the long-term stability and test-retest reliability of these data. To ensure product reliability with the fewest possible tests, Ahmed & Chateauneuf (2014) [11] suggested an optimization-based formulation that couples the expenses of product design with validation testing. Li et al (2014) [12] investigated the Micro-Electro-Mechanical Systems (MEMS) microphone's dependability using two accelerated life tests: shock impact testing and mixed flowing gas (MFG) testing.…”

The control of processes is made smooth and effective by Programmable Logic Controllers (PLCs), which are essential to industrial automation. The assessment of PLCs' reliability is crucial since more and more sectors depend on them for crucial tasks. In-depth reviews of the components necessary to evaluate PLC system reliability are presented in this study. To ensure a robust review, the review first clarifies the basic concepts of reliability, highlighting the significance of system uptime and the ramifications of failures in industrial settings. Next, it examined the different elements that go into a PLC's overall reliability, such as availability, testability, and (maintenance and maintainability). The percentage of the reviewed papers that employed (maintenance and maintainability), testability, or availability to improve the reliability of PLC systems showed that, availability and (maintenance and maintainability) has been employed the most for enhancing system reliability, accounting for 32% each of publications analyzed, followed by testability, accounting for 28% respectively. The scatter chart that depicts the progression of reliability components from 2010 to 2023 also explained that the use of availability and (maintenance and maintainability) was increasing. This upward trend can be explained by the fact that repairable systems are heavily reliant on availability, whereas (maintenance and maintainability) tend to avoid unnecessary equipment breakdown and testability, which ensures the ease with which the functionality of any system or component can be ascertained with the required level of precision.

“…Many works then try to optimize the test design (Luecht, 2013). In particular, optimizing the number of tests, based on costs, coupling product design costs, and validation test costs, to ensure product reliability (Ahmed and Chateauneuf, 2014). Other works deal with experimentation, and the cost of experimentation, with the idea of seeing if there are ways to minimize the costs of learning through parallel strategies (Gillier and Lenfle, 2019;Thomke, 2003).…”

Renovating Engineering Departements’ Creation Heritage to Meet Contemporary Challenges: Frugal Validation Patterns and Constructive Proof Logics for New Engineering Rules

et al. 2023

Engineering departments design infrastructure by applying rule systems. The latter are an old creation heritage, based on decades of engineering, that makes it possible to design and govern the operation of the physical heritage which is the infrastructure. Replacing the infrastructure is not sustainable in the meaning of grand challenges; renovating it by applying engineering rules is but could appear too expensive. The literature highlights situations where renovation by respecting the state of the art is too costly and so is the validation of new renovation rules. Are there forms of frugal validation that allow for sustainable renovation of existing systems? This paper tries to explore a third way, a renovation of the physical heritage from a renovation of the system of rules, conceiving in the system of rules, new propositions, and their validation. Using the C-K theory, a case analysis was performed within the French national rail network manager (SNCF Network), a company that has a historical engineering heritage and is at the same time implementing a renovation of it. The paper shows that the renovation of engineering departments’ creation heritage can go through frugal validation patterns and constructive proof logics.

“…Ziel ist, über die geplanten V&V-Aktivitäten alle kritischen Fehlerarten zuverlässig abzusichern. AHMED und CHATEAU-NEUF [13] bearbeiten in ihrem Beitrag die Fragestellung, welche Anzahl an Tests optimal ist, um die Zuverlässigkeit bei angemessenem Konfidenzlevel sicherzustellen. Dabei berücksichtigen sie Produktkosten, Fehlerkosten und Testing-Kosten.…”

The model of PGE product generation development describes a product that has no direct previous generation as so-called product generation 1 (G1). Development in such a G1 environment poses special challenges that affect the development process: G1 development with a shortening of the time-to-market paired with a high pressure to innovate usually takes place without much experience knowledge. As a result, an increased number of technical changes, known as variations in the PGE model, is observed at a late stage of development. This is accompanied by the question of what testing activities are necessary to verify or validate (V&V) these variations. The focus of the paper lies on the analysis of the G1 challenges. The general procedure of the systematic that links the variations with the possible V&V activities is presented.
