Direct Planning Project lets you create links to show the precedence of jobs scheduled for different resources.
Kinds of links
Links between jobs are end-to-start links, that may be of several kinds:
- Classical link: target job can only start when source job is over.
- Link with overlapping: target job can start before source job is over.
- Link with shifting: target job can only start after the source job has finished for some time (security time, transportation time, sub-contracting time, etc.)
Using the links with shifting, together with milestone jobs, enable modeling sub-contracting in the schedule. To model a return from sub-contracting earliest start date.
