    <dc:description># MDRP-SSD-Instances
Benchmark instances for the MDRP-SSD


## Instance naming

Each instance is named:

```text
MDRP-SSD-n-r.txt
```

where `n` is the number of customer ships and `r` is the replicate number. For example, `MDRP-SSD-10-2.txt` is the second instance with 10 customer ships.

The archive contains 48 instances, with three instances for each problem size from 5 to 20.

## Instance format

Each file contains the following global parameters:

- `MOTHERSHIP_SPEED`: mothership speed in km/min
- `DRONE_SPEED`: drone speed in km/min
- `DRONE_ENDURANCE`: maximum sortie duration in minutes

The `NODE_SECTION` contains:

| Field | Meaning |
| --- | --- |
| `ID` | Node identifier; node 0 is the shore depot |
| `X0`, `Y0` | Initial node coordinates in km |
| `VX`, `VY` | Node velocity components in km/min |

The shore depot is stationary. The position of customer ship \(i\) at time \(t\) is
\[
\left(X0_i+VX_i t,\;Y0_i+VY_i t\right).
\]

All numerical values are provided to two decimal places.</dc:description>
