You might want to take a look at our product called WorkTime for Windows
and Macintosh. It does automatic scheduling for employees and other
resources, based on various attributes that you define (e.g., jobs, skills
levels, locations, etc.). You can also specify when employees are
available to work and place limits on their working hours. In creating
schedules, you specify time-slots that dictate when you need people with
various attributes and then WorkTime tries to fill the slots. You can also
fill them manually or fill them combining both automatic and manual
features.
