A predictive maintenance cost model for CNC SMEs in the era of industry 4.0

Abstract

Within the subject area of maintenance and maintenance management, authors identified a deficiency in studies focussing on the expected value from adopting Predictive Maintenance (PdM) techniques for Machine Tools (MT)s. Authors identified no studies focusing on presenting a PdM value analysis or cost model specifically for Small-Medium Enterprise (SME)s operating Computer Numerically Controlled (CNC) MTs. This paper's novelty is addressing SMEs minimal representation in literature by explanatorily collecting data from SMEs within the focal area via surveys, modelling and analysing datasets, then proposes a cost effective PdM system architecture for SME CNC machine shops that predicts cost savings ranging from £22,804-£48,585 over a range of 1-50 CNC MTs maintained on a Distributed Numerically Controlled (DNC) network. Affirms PdM's tangible value creation for SME CNC machine shops with predicted positive impacts on their MTs cost and performance drivers. These exploratory research findings corroborates SMEs pooling together to optimize their CNC MT maintenance cost through the recommended system architecture. Finally, introduces opportunities for further PdM research taking into account SMEs' perspective. The paper's industrial application is confirmed from the surveyed SMEs that demonstrated their current utility of PdM; then anonymous positive feedback on the online dashboard, shared with participant companies, confirmed the research results supported SMEs in considering exploring the path to adapting PdM. It is anticipated that beneficiaries of this research will be maintenance managers, business executives and researchers who seek to understand the expected financial and performance impact of adopting PdM for a MT's overall life cycle costs.

Systematic Literature Review Predictive Maintenance Solutions for SMEs from the Last Decade

“…Although it is not reasonable to apply this strategy to every maintenance object in the company, they propose a roadmap for how to find an optimal mix of maintenance strategies and, therefore, to minimize maintenance costs. In addition, Adu-Amankwa et al [23] focused on developing a cost model that assists SME machine shops in evaluating the benefits of adopting PdM techniques, using financial modeling and strategies that build on maximizing values. This was achieved by collecting and analyzing data from SME CNC machine shops in the UK that utilize PdM techniques and measure their impact on the performance cost.…”

“…Requires a systematic process for service innovation by digital technology Implement a culture of failure in the organization Finally, although PdM programs promise significant benefits, Adu-Amankwa et al [23] mapped a summary of the additional responsibilities and challenges of PdM, including unreliable data or a calibration error, special training required and costs for system analysis, maintenance and security of data infrastructure, and significant investments in the acquisition cost.…”

A manutenção de ativos no contexto da Indústria 4.0: uma análise bibliométrica e sistemática

“…A adesão às tecnologias da Indústria 4.0 propicia um avanço na manutenção preditiva, ou seja, faculta monitorar os equipamentos de forma constante de modo a prever falhas de maneira prematura (He et al, 2018;Guizzi et al, 2019;Bengtsson & Lundström, 2018;Romero-Torres et al, 2017;Tedeschi et al, 2018;Adu-Amankwa et al, 2019).…”

“…A manutenção é realizada por meio de sensores que são acoplados nos equipamentos e enviam informações para a computação em nuvem através de sistemas específicos (Mourtzis & Vlachou, 2018;Romero-Torres et al, 2017;Bengtsson & Lundström;Tedeschi et al, 2018;Adu-Amankwa et al, 2019).…”

Research on Risk Analysis and Countermeasures of Micro Store Operation Model

“…Micro-shops are an online shopping platform for the masses. Anyone can register their shop by mobile phone number (Adu-Amankwa et al, 2019;Al-Bayati & Al-Zubaidy, 2020;Almeida et al, 2019). Compared with other platforms, an operation is more It's simpler and easier to get started.…”
