#016: Can your PM do this? - Part II

#016: Can your PM do this? - Part II Is your PM predictably intelligent? Introducing ContinuousPdM! Note: This is Part 2 of the ContinuousPdM series. Part 1 of this series can be found here. There are several steps in developing a Predictive Maintenance model. These steps are discussed in detail below. Data Gathering Leveraging data from diverse sources enhances the quality of predictive maintenance immensely. Predictive maintenance offers a significant advantage over preventive maintenance by minimizing unplanned downtime through the anticipation of failures and the prevention of both over-maintenance and under-maintenance. The effectiveness of this approach heavily relies on the quality of data harnessed by the machine learning-based artificial intelligence tool. Sensors For predicting failures in the future, predictive maintenance utilizes historical data from sensors which measure values for a multitude of parameters such as: Vibration One of the most widely used sensor across the PdM industry especially for rotating machines is the Piezo accelerometer or the MEMS accelerometer, both of which are used for vibration measurements. The data from these sensors can be used to find target faults in bearing condition, gear meshing, misalignment, load condition, etc. Sound Ultrasonic microphones are used to record sounds at high frequencies from machinery, and can be used to detect pressure leaks, imbalance etc. Temperature Sensors such as RTDs, and thermo-couplers are used to measure process temperatures, for example. Other parameters can include bearing temperature, lubrication temperature, cooling water temperature, etc.. These were a few of the sensors from which data is usually gathered when we consider the context of predictive maintenance. Data from various other sensors such as oil quality, magnetic field, operational field, proximity, electrical and many more can be gathered to predict faults in machinery. Maintenance (CMMS) Data A consolidated archive of historical data consisting of maintenance tasks performed on an asset over time is crucial for modeling. This can comprise of past records component replacements, duration of downtime due to component failures, can be used for failure pattern recognition, Remaining Useful Life (RUL) estimation, and maintenance optimization. Data Pre-processing Data from a multitude of sources is used to prepare a machine learning model which is capable of performing predictive maintenance, and hence it is imperative to make sure that the data is well-aligned and organized to the chosen model. Various pre-processing techniques need to be applied in order to clean the data, ensure its consistency and is properly formatted. Handling Missing Data Deletion Techniques This technique removes entire rows or records that contain any missing values. It is simple but can lead to loss of a significant amount of data and reduced statistical power. Imputation Techniques Missing values can also be replaced using mean/median imputation where the missing data is replaced with either mean, median or mode of the available data. Regression models can be used to perform Regression Imputation to handle missing values or Multiple Imputation techniques such as Multivariate Normal Distribution, Chained Equations (MICE) or algorithms such as Random Forests, k-nearest neighbors, or neural networks can be used to impute missing values. Model-based Techniques Maximum Likelihood Estimation models estimate missing parameters by estimating the likelihood function of the observed data without imputing the missing data. Expectation-Maximization (EM) Algorithm is an iterative method that finds the maximum likelihood estimates of parameters in probabilistic models with missing data. Handling Outliers Statistical methods, like calculating z-scores, standard deviation, median absolute deviation, or determining the inter-quartile range, are valuable tools for detecting potential outliers that fall beyond the normal range of a particular parameter. Machine learning algorithms such as Local Outlier Factor (LOF) which computes the local density deviation of a data point with respect to its neighbors to identify outliers, along with Isolation Forests and one-class SVMs can be used. Ensemble methods which combine multiple such algorithms can also be used in tandem to improve accurate outlier identification. While outliers can notably decrease model accuracy across various datasets, anomalies in parameter values are essential for predictive maintenance tasks. Therefore, it is imperative to approach statistical techniques with caution. Data Normalization Some of the commonly used normalization techniques in predictive maintenance include z-score normalization which scales features to have a mean of 0 and a standard deviation of 1. Other techniques used for normalization are log transformation, decimal scaling, and min-max scaling. Feature Engineering Time based Feature Engineering Lag Analysis This technique involves creating new features by shifting the time series data by a certain number of time steps (lags). This captures the temporal dependencies and autocorrelation in the data. It also involves calculating statistical measures (mean, max, min, etc.) over a rolling window of time steps. This can capture short-term patterns and trends. Decomposition Time series decomposition is a technique that breaks down a time series into its constituent components, typically trend, seasonality, and residual components. This allows for better understanding and modeling of the underlying patterns and behaviors present in the time series data. The decomposed components can be used as separate features or combined in various ways to improve the performance of predictive models. Stationarity Tests Stationarity tests are statistical tests used to determine if a time series data is stationary or non-stationary. They are crucial before applying time series forecasting models, as most models assume stationarity. Common stationarity tests include the Augmented Dickey-Fuller (ADF) test and the Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test, which test for the presence of unit roots and stationarity around a deterministic trend, respectively. Frequency based Feature Engineering Autocorrelation Analysis It measures the correlation between a time series and its own lagged values, revealing repeating patterns and seasonality. It helps identify the optimal lag order for modeling and forecasting time series data. Seasonal Subplots This technique involves creating subplots of the time series data grouped by a seasonal component (e.g., months, days of the week) to visually inspect and identify seasonal patterns and trends Spectral Analysis It involves transforming the time series data from the time domain to the frequency domain using techniques like Fast Fourier Transform (FFT). This allows identifying dominant frequencies, periodicities, and cyclical patterns in the data. Feature Engineering for Classification Numerical Transformations These techniques transform numerical features to a different scale or distribution, such as log transformation, square root transformation, or Box-Cox transformation. They are used to make the data more suitable for certain algorithms or to reduce the influence of outliers. Encoding Categorical Data This involves converting categorical variables into a numerical representation that can be used by machine learning algorithms. Common techniques include one-hot encoding, label encoding, target encoding, and others, each with its own advantages and trade-offs. Dimensionality Reduction These methods aim to reduce the number of features in a dataset while retaining most of the relevant information. Popular techniques include Principal Component Analysis (PCA), t-SNE, Factor Analysis of Mixed Data (FAMD), and others. They can help with visualization, reducing noise, and improving model performance. Machine Learning Modeling In the realm of predictive maintenance, various machine learning models are commonly employed, such as decision trees, random forests, support vector machines, and neural networks like LSTMs. The selection of a model hinges on factors like data intricacy, type of problem, interpretability requirements, and trade-offs between performance and resources. Furthermore, the amalgamation of multiple models through ensemble methods has the potential to enhance accuracy significantly. We adapt a 2-step approach to predict maintenance window in the near-future. The first step includes the prediction of parameter values in future, and the second step includes the prediction of the type of failure using the values predicted using time-series analysis. STEP 1: Time Series Forecasting Autoregressive Integrated Moving Average (ARIMA) models play a significant role in time series forecasting within the realm of predictive maintenance. These models excel at capturing trends, seasonality, and autocorrelation present in the data, making them a valuable tool for predicting future sensor values. On the other hand, Recurrent Neural Networks (RNNs), specifically Long Short-Term Memory (LSTM) networks, are adept at handling sequential data such as time series. Their strength lies in capturing long-term dependencies, rendering them highly effective in forecasting future sensor values. STEP 2: Error Classification Modeling Support Vector Machines (SVMs) stand out as robust supervised learning algorithms proficient in executing both binary and multi-class classification tasks. Within the realm of predictive maintenance, SVMs prove invaluable for categorizing equipment condition as either "healthy" or "faulty," as well as for discerning various failure types. Moreover, decision trees and random forests play a pivotal role in predictive maintenance by categorizing equipment condition, pinpointing failure modes, and shedding light on the key features that contribute to failures. Complementary algorithms such as Isolation Forest, One-Class SVM, and Local Outlier Factor find utility in anomaly detection, a type of unsupervised classification. In the context of predictive maintenance, anomaly detection serves to flag abnormal equipment behavior or sensor readings, which could serve as early indicators of potential failures or deterioration. Dashboarding and Reporting in Power BI In our journey to revolutionize preventive maintenance, we’re developing powerful ways to visualize data using Power BI.

#015: Can your PM do this?

#015: Can your PM do this? Is your PM predictably intelligent? Introducing ContinuousPdM! The birth of ContinuousPdM - Intelligent Predictive Maintenance…….. Once upon a recent time, a talented xLM AI-ML Engineer was on an assigment to change a customer's antiquated PM program to a modern, intelligent, data driven, predictive program. Here is the conversation that ensued: Ram (xLM AI/ML Engineer): Good morning, Rob I am here to breathe some fresh air into your PM program. Rob: Why? What? My PM program is just fine. Has been for many years now. Ram: When you say fine, you really mean it seriously, right? Rob: Of course! We do everything by the book on a weekly, monthly, quarterly, yearly...... Ram: Great! Does that mean there are absolutely no line failures and no line downtime? Rob: That is not my area. I am in PM. Ram: If PM is really working, why are there major failures? Let me ask you this. Is your PM data driven? Rob: Nope. It is fixed schedule driven. Ram: I know you guys collect a lot of data. How come it is not tied into the PM program. Rob: What has data to do with PMs. PMs are done on a periodic basis. Ram: Then how do you know that the PMs are working effectively? Rob: Again PMs are done on schedule, every week, month, quarter, year. Ram: (Turning to the audience now) Preventive needs to move to an intelligent, data driven, ROI based, predictive system. PREVENTIVE is just bad business. It is like working without knowing how much one will get paid. Maintenance is meant to maintain the uptime with intelligence based on data. Introducing ContinuousPdM (Intelligent Predictive Maintenance not "preventative") The PM Background “Preventive” is so glued into our work culture that it literally means doing certain “useful” tasks on a periodic schedule not really worried about ROI or Line Downtime. In fact, the PM schedules cause a lot of line downtime. Lines like to run all the time. They don’t like to take a rest while someone opens up their gut and start running again. A high speed mass manufacturing line growls and literally cries when it hears the word “PM”. Hey, PM is supposed to give the line a healing touch. Does it really? In fact it adds to the downtime and most lines take a long time to recover before they really wake up and start running at full speed. A line stuttering and growling! Let us step back and ask ourselves why are we doing something that is so expensive time and again, and so religiously without questioniong the ROI or the logic behind all the PM tasks. Does it make any engineering sense? Doesn’t it make sense to identify the root causes of the most expensive line burnouts in any given year and make sure such a thing does not happen again. How is this possible? One of the trains to get on is intelligent predictive maintenance. Predictive Maintenance (PdM) Predictive Maintenance is a proactive approach to maintaining assets and equipment by using data analytics and machine learning to detect potential failures before they occur. Manufacturing companies can monitor sensor data from production machinery and equipment. By analyzing historical data on equipment performance, vibration patterns, temperature readings, and other metrics, an intelligent platform can build predictive models to forecast when components are likely to fail or require maintenance. This allows manufacturers to schedule maintenance activities during planned downtimes, reducing unplanned outages and increasing asset utilization. In the manufacturing sector, AI and ML have proven to be game-changers for predictive maintenance, enabling organizations to optimize asset performance, reduce downtime, and improve overall operational efficiency.

This allows manufacturers to schedule maintenance proactively, reducing unplanned downtime and associated costs. For example, AI can detect anomalies in vibration patterns or temperature readings, indicating potential bearing failures or overheating issues in production lines. Condition Monitoring for Automated Assembly Lines Automated assembly lines are the backbone of many manufacturing processes. AI-powered condition monitoring continuously analyzes sensor data from robotic arms, conveyors, and other automated systems to identify deviations from normal operating conditions. This early warning system enables maintenance teams to address potential issues before they lead to failures, minimizing disruptions and ensuring smooth production flows. Predictive Quality Control AI and ML can be applied to predict quality issues in manufacturing processes by analyzing data from various sources, such as sensor readings, process parameters, and historical quality data. This predictive quality control approach enables manufacturers to identify and address potential quality issues before they occur, reducing waste, rework, and customer complaints. Optimized Maintenance Scheduling AI and ML models can analyze data from multiple sources, including maintenance logs, sensor data, and production schedules, to optimize maintenance schedules for various assets and equipment. This approach ensures that maintenance activities are performed at the most appropriate times, minimizing disruptions to production while maximizing asset availability and lifespan. Predictive Inventory Management By leveraging AI and ML to predict equipment failures and maintenance needs, manufacturers can optimize their inventory management processes. This includes forecasting spare parts requirements, ensuring timely procurement, and minimizing excess inventory, ultimately reducing costs and improving operational efficiency. Root Cause Analysis AI and ML can assist in root cause analysis by identifying patterns and correlations in data from various sources, such as sensor readings, maintenance logs, and operational parameters. This helps manufacturers pinpoint the underlying causes of equipment failures or quality issues, enabling them to implement effective corrective and preventive actions. By embracing AI and ML for predictive maintenance, manufacturers can transition from reactive to proactive maintenance strategies, optimizing asset performance, reducing downtime, and improving overall operational efficiency, ultimately leading to increased productivity and profitability.

This includes establishing policies, procedures, and regular reviews. Predictive Model Development: An Use Case In the highly competitive realm of manufacturing, predictive maintenance plays a crucial role in boosting operational efficiency, reducing downtime, and prolonging the lifespan of essential assets. Let's delve into how manufacturers can harness the power of data science and machine learning to develop reliable predictive maintenance systems, accompanied by a practical use case: Use Case: Predictive Maintenance for Conveyor System Bearings Background: A manufacturing plant experiences frequent unplanned downtimes due to bearing failures in its conveyor systems. These downtimes result in significant productivity losses and high maintenance costs. Objective: Develop a predictive maintenance system to forecast bearing failures and schedule maintenance proactively. Integrate Diverse Data Sources To conduct a thorough analysis and create predictive models, it is essential to integrate a variety of data sources. These sources may encompass machine-level sensors, maintenance logs, operational parameters, and historical performance records from platforms like CMMS, Historians, etc.. This extensive data compilation plays a vital role in pinpointing pertinent features and variables, offering solid evidence to support any solutions formulated from the analysis. Data Sources: Sensors: Vibration (Hz), Temperature (°C), and Operational Load (kg). Maintenance Logs: Records of past bearing replacements and failures. Operational Parameters: Conveyor speed (m/s), operational hours, and load. Assemble a Specialized Team Forming a team comprising data scientists and subject matter experts with a wide range of skills in machine learning, manufacturing, and operations is essential. This interdisciplinary team will work together to pinpoint pertinent features and variables from the consolidated data outlets and create precise predictive models. The amalgamation of their expertise guarantees that the models are not only technically robust but also feasible in real-world scenarios. Steps for Predictive Modeling Understand the Use Case: Clearly defining the specific problem or use case is crucial for operational contexts like a manufacturing plant aiming to predict and prevent bearing failures in its conveyor systems. This involves a deep understanding of the equipment types, operational environments, and potential failure modes they may encounter. Gather Data: Collecting data from a variety of sources is crucial for comprehensive analysis. This can involve information gathered from sensors measuring parameters like vibration and temperature, maintenance logs detailing previous bearing failures, operational data such as load and speed, and historical performance records like those stored in a Computerized Maintenance Management System (CMMS). An instance of this data could encompass vibration readings measured in Hertz, temperature recorded in Celsius, and operational hours logged. Clean and Prepare Data: To ensure the data is well-prepared for analysis, it is crucial to focus on cleanliness, consistency, and proper formatting. This process includes eliminating anomalies (such as unusual temperature spikes that do not align with real failures), filling in any missing values (utilizing interpolation techniques), and standardizing the data (scaling vibration measurements to a uniform range). Perform Feature Engineering: Identifying and establishing pertinent features is crucial for predictive models. For instance, in the scenario of bearing failure, relevant features could encompass the average vibration frequency, temperature variance, and operational load. Feature engineering is a process that revolves around choosing variables that hold substantial influence over equipment performance and potential failure modes. Apply Machine Learning Techniques: Apply supervised and unsupervised learning methods according to the specific use case. In supervised learning, labeled data (such as instances of previous bearing failures) is utilized to train models. On the other hand, unsupervised learning is capable of recognizing patterns in operational data even in the absence of predefined labels. For instance, a supervised learning model could leverage historical data to forecast the likelihood of bearing failure occurring within the upcoming 100 operational hours. Validate the Model: Validate the predictive models by leveraging historical data and real-world scenarios. Utilize cross-validation methods (e.g., k-fold cross-validation) to guarantee the accuracy and resilience of the model. Define performance metrics such as precision, recall, and the F1 score to evaluate the model's efficacy. For instance, a model could demonstrate a 90% precision rate in forecasting bearing failures.
