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;
In operations research, Johnson's rule is a method of scheduling jobs in two work centers. Its primary objective is to find an optimal sequence of jobs to reduce makespan (the total amount of time it takes to complete all jobs).
For example, if 32 hours of billable time are recorded in a fixed 40-hour week, the utilization rate would then be 32 / 40 = 80%. Note that with this second method it is possible to have a utilization rate that exceeds 100%. If 50 hours of billable time are recorded in a fixed 40-hour week, then the utilization rate would be 50 / 40 = 125%.
where U is the utilization factor, C i is the computation time for process i, T i is the release period (with deadline one period later) for process i, and n is the number of processes to be scheduled. For example, U ≤ 0.8284 for two processes. When the number of processes tends towards infinity, this expression will tend towards:
In operations research, the makespan of a project is the length of time that elapses from the start of work to the end. This type of multi-mode resource constrained project scheduling problem (MRCPSP) seeks to create the shortest logical project schedule, by efficiently using project resources, adding the lowest number of additional resources as possible to achieve the minimum makespan. [1]
The goal is to achieve 100% utilization but that is very unlikely, when weighted by important metrics and subject to constraints, for example: meeting a minimum service level but otherwise minimizing cost. A Project Resource Allocation Matrix (PRAM) is maintained to visualize the resource allocations against various projects.

The reserve portion of the ratio is the amount of a resource known to exist in an area and to be economically recoverable (proven reserves). The production portion (denominator) of the ratio is the amount of resource produced in one year at the current rate. [1] RPR = (amount of known resource) / (amount used per year)
