# Selecting RSL Tasks Based on Specs - Background

## What

RSL Care Strategies provide decision logic that determines, based on FLOC and Equipment data (for example, Specs), whether a task can be applied.

In addition to the Location type, Equipment group and CMMS type, you can also rely on criteria from the FLOC and Eq **Specs** to steer RSL application.

| Reliability Aspect | FLOC/Equipemnt Specifications |
| --- | --- |
| Downtime | BYPASS AVAILABILITY |
| Environment – Gas Emission | FUGITIVE EMISSION PERMIT |
| Erosion – Corrosion | ECS SEVERE SERVICE |
| High Temperature | ECS TEMPERATURE OVER 400 |
| Sensitive Trim | TRIM CHARACTERISTICS |
| Blockage | ECS FOULING SERVICE |
| Time-Based Degradation | ECS OVERHAUL REPLACEMENT |

The decision logic applied to tasks can cover multiple Specs per task involving value ranges and AND/OR logic.

The Specs on the FLOC and Equipment can originate from a connected CMMS like SAP (interfaced) and a subset of Specs specified in IMS.

## WHY

Client interest requested more powerful functionality to assign maintenance strategies to FLOCs and Equipment. For instance, when FLOC and Equipment Specs are available from SAP, it is good practice to selectively assign maintenance strategies. Alternatively, when applying Selective RSL's, you can use the specs to select a particular FLOC or Equipment and assign multiple individual RSLs to it.

A possible situation where a more powerful maintenance strategy assignment can be relevant is in the detailed engineering phases of capital projects, where it can be used to deliver preventive maintenance plans.
