The technique for establishing and maintaining priorities among various jobs of a project is known as

Event flow scheduling technique: The principle of this technique is based on the work breakdown structure of operations. Events and activities are interconnected in a logical sequence.

Short interval scheduling: It is a technique of managing and planning a project, which is responsibly selecting for scheduling one of the operations among various operations to execute form ready state.

Critical ratio scheduling: It is a technique for establishing and maintaining priorities among the jobs in a factory. The critical ratio is an index and sets the relationship between when a product is required and when it can be supplied.

\({\rm{Critical\;ratio}} = \frac{{{\rm{Demand\;time}}}}{{{\rm{Supply\;lead\;time}}}}\)

Note:

1. The critical ratio gives priority to jobs that must be done to keep shipping on schedule.
2. A job with a low CR (less than 1.0) is one that is falling behind schedule.
3. If CR = 1.0 (exactly), job is on schedule.
4. If CR > 1.0, means the job is ahead of schedule & has some slack.

Slotting technique for scheduling: It is the technique for planning and managing work in which various operations are divided into slots so that conflict while execution does not happen.
