A project decision · A Mariña Glass

One worker can handle two car washes. The scheduler had to allow it.

The calendar kept the worker busy for the entire job. I added an exception for two simultaneous washes, keeping a separate bay for each vehicle and checking capacity again when saving.

This rule only applies to standalone, single-worker washes at the workshop. Shifts, staff blocks and buffers still apply.

The jobs overlap from 10:30 to 11:00. Each vehicle keeps a 15-minute buffer after its wash.

A third wash at 10:45: no capacity. The scheduler rejects it.
