Q5. What are the typical challenges you face during design and development of a Predictive Maintenance Solution? How have you been addressing them?
Ans. One of the main challenges associated with developing an IoT based Predictive Maintenance Solution is the fact that there is no universal/ one-size-fits-all predictive maintenance framework.
Every industry facility is unique, with its own set of “specialized information” to be collected for reliable Enterprise Asset Management.
To achieve desired business objectives, a Predictive Maintenance solution needs to be tailor-made for the specific industrial use case, taking into account the behavior and design parameters of the production line.
Thus, the success of the Predictive Maintenance project is dependent on the following factors:
- Identifying the data collection and data management requirements – this includes defining what data is to be gathered and planning how and where (on-cloud or on-premise) the data will be processed.
- Defining the metrics and parameters to monitor the industrial equipment, as this forms the basis of the entire maintenance operations.
At Embitel, our IoT experts conduct detailed workshops for our clients to discuss and define their industrial asset Management goals and design a customized IoT Predictive Maintenance solution for them.
Q6. On-Premises or on-cloud – Which one is ideal for my business? Where does the data analysis take place- on the physical servers or on the cloud?
Ans. The decision to choose between an On-premise & On-cloud model for storage & processing of your industrial asset data depends on the following factors:
- The allocated budget for the project
- Annual operating costs
- How much and what all type of data is to be stored (like real –time data, historical data etc.)
- Number of times devices or equipment are used daily for operations (this is important to identify its criticality).
- Number of times the equipment has to be analyzed.
Q7. Is it possible to integrate your Predictive maintenance solutions with the legacy industrial assets and production systems?
Ans. Our Predictive Maintenance solutions can coexist with the legacy industrial assets and production systems as long as there is a well-defined software protocol that gathers the data, externally from the equipment.
Q8. How do you identify the relevant data from the huge volume of Raw Data generated by the systems?
Ans. At Embitel, we have developed in-depth expertise in filtering techniques (using Python script and statistical models) necessary to identify relevant data from the humungous amount of raw data.
Our teams have deep understanding of the data cleansing techniques and they ensure that the filtered data is error-free and reliable
Ans. The criticality of accuracy of the results delivered by Predictive Analytics varies as per the use-case.
For example, 99% accuracy in predicting equipment failure is very critical for safety-intensive applications such as medical equipment, automotive applications, factory shop-floors, etc.
We can help you achieve 99% accuracy in predicting equipment failure, provided we have access to a large volume of valid data sets (historic data- error logs, failure and successful events).
If the volume of available and relevant data logs is less, then 85-95% accuracy can be achieved.
