'''Linear Schedulingscheduling Methodmethod''' ('''LSM''') is a graphical scheduling method focusing on continuous resource utilization in repetitive activities. It is believed {{Who|date=August 2009}} that it originally adopted the idea of [[Line-Of-Balance method]].

==Application==

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 or linear projects. The main advantages of LSM over [[Criticalcritical Pathpath Methodmethod]] (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 [[Experience curve effects|learning curve]] phenomenon is minimizedmaximized

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

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

==Alternative names==

AccordingSpecific tonames for the linear scheduling method have been adopted, such as:<ref name="kenley2010">{{cite book |last1=Kenley |first1=Russell |last2=Sepp&auml;nenSeppänen |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>, specific names for the linear scheduling method have been adopted, such as:
