I want to schedule tasks that are generally similar in nature but are from
different sub-projects, and I can't figure out how to do this. One
constraint is that the different tasks involve the same resource. Some
examples might help:
1. On a construction project there are activities, like laying foootings,
the base for a road etc. These are different sub-projects but, for this
example, not on the critical path. Concrete ready-to-lay is delivered to the
site regularly, so I would want concrete laying to be scheduled when the
concrete is on site (i.e. the trigger for the activity is the arrival on-site
of the concrete). I could do this by dependencies, but then I have to figure
which delivery of concrete they are going to be associated with.
2. In an operating theatre, best practice is to schedule operations so that
within each allocated session 'clean' operations are done before 'dirty'
ones. Overall, scheduling depends on the actual type of operation and
allocation to any specific session is dependent on its duration and the
availability of resources (i.e. normal dependency-based scheduling). There is
some flexibility in which operations are done but, only one 'dirty' operation
is allowed per session.
3. In a kitchen it's best to get the pastry work done before the main
kitchen starts getting busy (and hot). In a small establishment there are
limited resources (which means there is no separation between pastry chef and
grill chef etc). Making up the pastry is a different sub-project from
prepping, grilling, assembly of the dishes etc. Ideally I want pastry tasks
scheduled earlier in the day without constraining the projects by, for
example, specifying 2 hours of pastry work each day in the calendar.
Hopefully this gives an idea - I've been trying to get my head round the
solution without success. I see it as defining affinities between types of
tasks to get a more natural goruping of activities.
Any ideas gratefully received.
