where Lssij is the
start-to-start time lag between task i and task j. As seen in the
above-defined mathematical relation, there can be different relationship
types between task i and task j, but the defined mathematical
relation still remains valid. Jas´kowski and Sobotka (2006)
described their Evolutionary Algorithm as a system having the
inputs such as relationship structure, available resources and
resource requirements of each project task. With these inputs,
their system was able to find the shortest duration of performing
the project (Jas´kowski & Sobotka, 2006).
