'''Linear Scheduling Method''' (LSM) is a graphical scheduling method focusing on continuous resource utilization in repetitive activities. It is believed that it originally adopted the idea of [[Line-Of-Balance method]].

'''Linear Schedulingscheduling Methodmethod''' ('''LSM''') is a graphical scheduling method focusing on continuous resource utilization in repetitive activities. It is believed that it originally adopted the idea of [[Line-Of-Balance method]].

LSM is used mainly in construction industry to schedule resources in repetitive activities commonly found in highway, pipeline, high-rise building projects. These projects are called repetitive projects or linear projects. The main advantages of LSM over [[Critical Path Method]] (CPM) is its underlying idea of keeping resource work continuously. In other words, it schedules activities in such a way that:

==Application==

# resource utilization is maximized.

LSM is used mainly in the [[Construction|construction industry]] to schedule resources in repetitive activities commonly found in [[highway]], [[Pipeline transport|pipeline]], [[Skyscraper|high-rise building]] and rail construction projects. These projects are called repetitive projects or linear projects. The main advantages of LSM over [[Criticalcritical Pathpath Methodmethod]] (CPM) is its underlying idea of keeping resource workresources continuously at work. In other words, it schedules activities in such a way that:

# interruption in on-going process is minimized, including hiring-and-firing.

# effect of learning curve phenomenon is minimized.

# resource utilization is maximized.;

These benefits are achieved in LSM by schedule activity start date at the date which will provide such a continuous work flow for the resource. In contrast to CPM, this date scheduled by LSM is not the earliest possible start date of an activity. ...?

Graphical presentation of LSM is also another advantage over [[Critical Path Method]] when project consists of repetitive activities.

Specific names for the linear scheduling method have been adopted, such as:<ref name="kenley2010">{{cite book |last1=Kenley |first1=Russell |last2=Seppänen |first2=Olli |title=Location-Based Management for Construction |page=6 |year=2010 |publisher=Spon Press |isbn=978-0-415-37050-9 |chapter=Chapter 1: Introduction}}</ref>
