Linear scheduling method
 |
Linear Scheduling Method (LSM) is a graphical scheduling method focusing on continuous resource utilization in repetitive activities. It is believed [who?] that it originally adopted the idea of Line-Of-Balance method.
Application
LSM is used mainly in the construction industry to schedule resources in repetitive activities commonly found in highway, pipeline, high-rise building 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 phenomenon is minimized
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
According to [1], specific names for the linear scheduling method have been adopted, such as:
- Location-based scheduling (the preferred term in the book)
- Harmonograms
- Line-of-balance
- Flowline or flow line
- Repetitive scheduling method
- Vertical production method
- Time-location matrix model
- Time space scheduling method
- Disturbance scheduling
- Horizontal and vertical logic scheduling for multistory projects
- Horizontal and vertical scheduling
- Multiple repetitive construction process
- Representing construction
- Linear scheduling
- Time versus distance diagrams (T-D charts)
- Linear balance charts
- Velocity diagrams
