I need a custom predictive maintenance module developed using my factory's failure logs and maintenance history data, which is available in spreadsheet formats like Excel or CSV. The module should provide the following key insights: 1. Predict the time to the next failure. 2. Identify root causes of equipment failures. 3. Recommend optimized maintenance schedules. Please ensure the solution integrates with the given data format and applies the appropriate data analysis or machine learning techniques to deliver accurate and actionable insights. I am open to suggestions on workflow and implementation approaches that ensure accuracy and usability.
