Abstract: More than one construction sequencing alternatives may be available for a complex construction project. Besides temporal relationships between construction activities, the logic relationships should also be semantically represented in a construction scheduling. The representation of two typical logical relationships, i.e.exclusive alternative and co-existing, are firstly explored, and then the associations between those logical relationships are evaluated. Subsequently, a unified framework is developed to abstract both temporal and logical relationships among various activities. Furthermore, the rules defining the conversion from a complex schedule model to the corresponding mixed integer linear programming model are developed for developing model conversion software. Finally, an engineering case has been studied to demonstrate and verify the application of the developed tools.

Key words: project schedule, alternative sequencing program, temporal relationship, logical relationship, model conversion
