Resource Constrained Project Scheduling

In this project, you will construct a schedule for a medium-sized realistic manufacturing assembly problem. The data for this problem is contained in several files:

tasks.txt
Contains duration and resource use data for all tasks. The first line of the file is the number of tasks. Each of the remaining lines is formatted as follows:
task numbertask duration (mins)resource 1 usageresource 2 usage...resource 17 usage
Resources 14..17 are labor resources (but see below).
precs.txt
Contains task precedence data. The first line of the file is the number of precedences. The remaining lines are of the form
preceding task numbersucceeding task number
res.txt
Contains resource profile data. The first line of the file is the number of resources. The remaining lines are of the form
resource numbernumber of intervalsinterval 1 duration (min)interval 1 capacityinterval 2 duration (min)interval 2 capacity...
In practice, the first 13 (``zone'') resources have 1 interval, and the last 4 (``labor'') resources have 2 intervals. The idea is that the intervals represent ``shifts'', all of which start at time 0 and are repeated throughout the schedule. Thus, the zone resources are constant throughout the problem, and the labor resources alternate between day and night shifts (of 450 minutes each).

There are two variants of this problem: one slightly easier one and one harder one.

MD2
Ignoring the labor resources, find a good schedule which honors the zone resource constraints and precedence constraints.
MD4
Find a good schedule which honors all resource constraints.
Note that in both MD2 and MD4, tasks may be executed across shift boundaries, but cannot be broken up (``preempted'').

If you prefer, you can get the description from the original benchmark site, or my slightly cleaned up version of the original data file. Note that these versions differ from the above description in an important way: the labor resources in these old versions are first (unlike in tasks.txt and res.txt above)! Watch out for this difference if you take this approach.
