Project scheduling in Spider Project includes all traditional methods (like CPM and renewable resource levelling) and adds Quantity based scheduling (when activity durations are calculated basing on activity work volumes (physical quantities) and assigned resource productivities),

Skill scheduling (when the software selects which resources to assign based on their skills, productivities, costs and user-defined priorities),

Conditional scheduling (when software selects one of competing network paths basing on user-defined conditions on special switch activities).

Spider Project calculates feasible resource-constrained floats and determines Resource Critical Path (Critical Chain).
