Linear scheduling method (LSM) is a graphical scheduling method focusing on continuous resource utilization in repetitive activities.
Application
LSM is used mainly in the
construction industry
Construction is a general term meaning the art and science to form objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and co ...

highway
A highway is any public or private road or other public way on land. It is used for major roads, but also includes other public roads and public tracks. In some areas of the United States, it is used as an equivalent term to controlled-access ...

and rail construction projects. These projects are called repetitive or linear projects. The main advantages of LSM over
critical path method (CPM) is its underlying idea of keeping resources continuously at work. In other words, it schedules activities in such a way that:
# resource utilization is maximized;
# interruption in on-going process is minimized, including hiring-and-firing; and
# the effect of the
learning curve
A learning curve is a graphical representation of the relationship between how proficient people are at a task and the amount of experience they have. Proficiency (measured on the vertical axis) usually increases with increased experience (the ...
