The origin of CPM and PERT was used for specific military and commercial purposes. However, CPM network technique is insufficient to adopt work repetitiveness and space-based work productivity of high-rise building. Thus, linear scheduling methods such as LOB(Line of Balance), RPM(Repetitive Planning Method) and LS(Linear Schedule) have been developed and studied by many companies and researchers. However, when it comes to change the previous CPM network schedule to the linear schedule, the previous researches have not been well addressed work breakdown structure(WBS), space breakdown structure(SBS), and activity generation by combining WBS and SBS in order to present the activity in LOB chart. Given the circumstances of linear scheduling methods, we performed this research as follows. First, we studied previous researches related to linear scheduling methods and weighted the pros and cons of the previous researches and this study. We also proposed the method to combine WBS and SBS in order to present activities on linear schedule. Finally, we summarized this research and suggested the future studies. This research therefore proposes the method to effectively use the accumulated data of CPM network and at the same time generate activities in order to efficiently change CPM network schedule to LOB schedule.
