# Maintenance History Dashboard

## Overview

This dashboard provides information about the **Maintenance History** for one or more **Resources**.

## Folder

* Resource History

## Database

* DWH (queried via Cube using GraphQL)
* CDM (queried via OData)

## Data

* Mean Time Between Failures (MTBF)
* Mean Time To Recovery (MTTRec)
* Mean Time To Acknowledge (MTTA)
* Mean Time To Repair (MTTRep)

## Data Breakdown

| KPI | Description | Formula |Datasource |
| - | ----------------- | --- |-------|
| **Mean Time Between Failures (MTBF)** | Quantifies the average uptime of a system before a failure occurs. It reflects reliability - the higher the MTBF, the more time the equipment stays operational between failures. The data shown in this KPI is the average of the time that a Resource spends between Unscheduled/Scheduled Down states. | Operating Time ÷ Number of Failures | `resource_states` in [[user-guide-resourcecube]]|
| **Mean Time To Recovery (MTTRec)** | Reflects how long, on average, it takes to recover from a failure, that is, how long the Resource remains unavailable. The data shown in this KPI is the average of the total downtime that a Resource spends between Unscheduled/Scheduled Down states. | Total Downtime ÷ Number of Failures |`resource_states` in [[user-guide-resourcecube]]|
| **Mean Time To Acknowledge (MTTA)** | Indicates the average delay between failure detection and the start of the response. In other words, it is the delay between the time a Resource changes to Unscheduled/Scheduled Down states and the time it takes to start a Corrective Maintenance Activity Order. | Begin Repair Time - Acknowledge Time |`resource_maintenance` in [[user-guide-resourcecube]]|
| **Mean Time To Repair (MTTRep)** | Indicates the average time that it takes to physically fix the problem once work has begun. This means that it measures the time between the start and the completion of a Corrective Maintenance Activity Order. | Total Time to Fix Maintenance Activity |`resource_maintenance` in [[user-guide-resourcecube]]|

## Data Visualization

| Panel | Description | Datasource |
|-------|---------------|-------|
| **Evolution Per Day** | Displays the daily trend of MTBF, MTTRec, MTTA, and MTTRep over the selected time range.| `resource_states` and `resource_maintenance` in [[user-guide-resourcecube]]|
| **KPI Performance** | Displays the mean values of the selected KPI over the defined time range. | `resource_states` or `resource_maintenance` in [[user-guide-resourcecube]]|
| **Maintenance History View** | Lists the Maintenance History for the selected filters. The Maintenance History includes information on Maintenance Plans and Activities. | Data Sets MaintenanceOrder (CDM)|
