Cloud Pak for Data Group

Reduce your costs by scheduling maintenance at just the right time.

Unplanned maintenance is a key issue in a number of asset intensive industries such as telecommunications, manufacturing, oil and gas, and transportation. It can be extremely costly due to extended production downtimes. Not only do they result in high urgency repairs and investment in new machinery and parts, but unexpected production loss may affect supplier obligation and force a company to purchase products from its competitors, resulting in significant unanticipated costs.

Minimizing maintenance cost for one machine

Predictive maintenance uses predictive analytics and machine learning (ML) to determine the lifespan of a machine and the likelihood of it failing on a given day. An ML model can take into account all available information, such as sensor data, historical tasks and orders, past failure history, and maintenance history. As a result, it can help determine the optimal maintenance day for each machine based on its specific characteristics. The idea is to use this information to schedule maintenance before equipment fails but not before it is actually needed, avoiding unnecessary costs associated with repair and production loss.

Minimizing maintenance cost for many machines

This methodology works great when we consider one machine at a time and there are not conflicting priorities. However, once we start introducing some complexity, dependencies, and limited resources, determining the optimal schedule becomes more challenging. For example, how do we take into account limited resources? If our ML model predicts that Day 3 is the optimal maintenance day for three machines but only two maintenance crews are available, when is the optimal maintenance day for each machine?

Intelligent Maintenance: Machine Learning and Decision Optimization Working Together

While machine learning can take into account all available data and past history to predict the likelihood of failure for a given machine, decision optimization (DO) can take it a step further and generate a schedule that is optimal for a set of machines, subject to limited resources (e.g. maintenance crew availability), other constraints and dependencies (production plan and repair costs), and optimization metrics (minimizing total cost, maximizing customer satisfaction/meeting planned production, minimizing late maintenance). Not only does it offer us valuable insights, but it also generates an actionable schedule or plan.

For a detailed description of the Intelligent Maintenance accelerator please refer to the following blog

What's included?

• A structured business glossary of business terms.
• Sample data science assets

How does it work?

The glossary provides the information architecture that you need to govern the data about your equipment. And your data scientists can use the sample notebooks, predictive models and decision optimization model to accelerate data preparation, machine learning modeling and finding an optimal solution. The Machine Learning and Decision Optimization models are deployed for use in production.

The accelerator uses predictive analytics and machine learning to determine the optimal day to performance maintenance on each machine. The accelerator helps you schedule maintenance so that you:

• Don't waste time and money fixing equipment that is working well.
• Don't let equipment failure leave you idle and accruing unnecessary costs.

Optimize your maintenance schedule based on the costs that you will incur.

The accelerator includes a Sample application which shows an example of how the deployed models can be embedded into a Machine operators tooling to plan for scheduled maintenance.
