Quality & non-conformity management

Supply Chain and Quality: Artificial Intelligence as the main driver for high-quality performance 

In Supply Chain Management, managing disruptions is one of the biggest challenges for practitioners, impacting directly the delivery performance of the supply chain. Disruptions may stem from various sources, and implementing a relevant solution may be costly. With regards to the Aerospace and Defence Industry, supply chain quality is typically impacted by the quality of the products or components themselves transiting through the network.

The rate of non-conformity impacts supply chain flows by creating delays, generating unexpected problem-solving costs and ultimately degrading production throughput rate and takt time. Hence, keeping low rates of non-conformity are of paramount importance to maintain quality and supply chain performance optimal.

AI technologies improving Quality for Supply Chain Management 

Recent developments in Artificial Intelligence have proven to be disruptive for all issues related to quality and non-conformity, and can be applied effectively to the Aerospace & Defence Supply Chain.

In particular, advanced analytics integrating systems modelling, default classification & tracking as well as simulation for non-conformity propagation are particularly powerful. They enable the transformation of decision-making related to quality management, improving operational business processes and ultimately reducing disruptions.

In particular, Sopra Steria has identified three key domains where Artificial Intelligence adds the most value to Supply Chain Quality:

 

To support its clients along these areas, Sopra Steria has developed multiple AI assets and accelerators that are used as catalysts to reduce project development cost and accelerate their time-to-market.

#1: Process adherence

In the Aerospace & Defence industry, manufacturing steps are carefully designed with respect to upstream engineering requirements in order to ensure product reliability. The design of each part or component is indeed created with respect to different constraints, in particular performance, norms, traceability and certifications. These come also with precise manufacturing processes and steps to guarantee the conformity of the product to its quality requirements.

As a consequence, deviating from standard manufacturing processes that have been defined by engineering for quality purposes generally increases the risk of non-conformity. Tracking these deviations and measuring process adherence with Process Mining can be done by comparing the logs of activities occurring in the MES with the theoretical process as defined in Manufacturing Engineering.

Beyond process mining and by integrating other relevant features, an AI module can identify the correlation between the contexts of the deviation, in particular the environmental parameters, and the insights of the deviation. In that case, when practitioners decide to implement a corrective action plan, the AI module can also record the action to mitigate the risk of non-adherence and its final outcome.

This AI system is finally able to recommend, given a particular situation, an effective action plan automatically. Sopra Steria, with its AI and process mining capabilities, has developed assets to accelerate the identification of Supply Chain disruptions due to quality issues, and support the implementation of corrective action plans targeted towards practitioners.

#2: Intelligent Testing

In the field of Quality Management in Manufacturing or Supply Chain, a key best practice is the inspection (destructive or non-destructive) of the produced or delivered components. This enables the statistical estimation of indicators such as non-conformity ratio for a production batch and provides concrete insights enabling practitioners to get a better visibility on the risk of Supply Chain disruptions.

The main concern is optimizing when, where and how far inspections or tests must be performed. “Intelligent testing by AI” is a tactical decision support tool designed by Sopra Steria that helps quality practitioners sample the right components at the right frequency. By combining Machine Learning with a powerful probabilistic model of the manufacturing steps and the production flows, we are able to correlate the testing scenarios with a cartography of the quality risks, allowing decision-makers avoid any fuzzy context for quality traceability.

Moreover, the link between testing costs –number of tests, duration, etc.- and confidence intervals of the risks is determined, which provides key information to optimize the costs of the inspections or tests for a given confidence level. Products clustering is also used in order to mutualize when relevant, creating a new dimension –the product- of the solution for the decision support. Finally, the architecture of such AI solution is built to have adaptable parameters that evolve based on past performance and improving its efficiency through time.  

#3: Predictive tracking

In Supply Chain Management, anticipation is key to ensure delivery flows and pre-emptively avoid disruptions. The non-conformity performances impacting supply chain operations is consequently part of the information needed to be tracked and anticipated. To do so, AI is a key technology that provides valuable predictive information.

In particular, with respect to the procurement process, one of the major challenges is improving one’s assessment of the supplier performance, in particular related to the quality of the delivered components. By integrating a large multi-parametric environment including supplier characteristics, products, local and global industrial contexts but also exogenous context, AI technologies can track the quality performance of the suppliers and anticipate the risks of non-conformity ratios.

Visibility and anticipation are also critical in the field of quality management within the manufacturing processes. Machine Learning technologies are a powerful tool to predict how non-conformities appear and may arise along quality gates. They also enable a better understanding of root causes and early prevention of non-conformities at downstream quality gates.

Overall, Sopra Steria uses Machine Learning algorithms to better understand and anticipate as well as Bayesian Networks to propagate the risks of quality disruptions. Such AI technologies enable Sopra Steria’s clients to gain predictive insight into non-conformity risks, as well as detailed information on risk root causes and localization. Supply Chain or Manufacturing Managers can organize accordingly their resources to mitigate non-conformity risks and ultimately avoid unexpected costly disruptions.

Sopra Steria has helped several aerospace manufacturer in the implementation of AI-based decision support tool for Quality management improving Supply Chain performance. For instance, Sopra Steria has developed Suppliers performances tracking tools with predictive views. Sopra Steria also worked on a decision support tool to predict the potential non-conformity risks by anticipating the trajectory of different key parameters with Machine Learning.
