Expected Time of Activity i-j Solution

STEP 0: Pre-Calculation Summary

Formula Used

Duration of i-j = Earliest Occurrence Time of j-Earliest Occurrence Time of i
t_ij = TE^j-TEⁱ
This formula uses 3 Variables

Variables Used

Duration of i-j - (Measured in Day) - Duration of i-j is the expected time of activity i-j.
Earliest Occurrence Time of j - (Measured in Day) - The Earliest Occurrence Time of j is the earliest expected occurrence of event j when we consider activity i-j.
Earliest Occurrence Time of i - (Measured in Day) - The Earliest Occurrence Time of i is the earliest expected occurrence of time of event i, when we consider an activity i-j.

STEP 1: Convert Input(s) to Base Unit

Earliest Occurrence Time of j: 24 Day --> 24 Day No Conversion Required
Earliest Occurrence Time of i: 19 Day --> 19 Day No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_ij = TE^j-TEⁱ --> 24-19

Evaluating ... ...

t_ij = 5

STEP 3: Convert Result to Output's Unit

432000 Second -->5 Day (Check conversion here)

FINAL ANSWER

5 Day <-- Duration of i-j

(Calculation completed in 00.020 seconds)

What is an Event and an Activity?

An event represents the accomplishment of some task. In a network diagram, beginning and ending of an activity are represented as events. Each event is represented as a node in a network diagram. An event does not consume any time or resource. Each network diagram starts with an initial event and ends at a terminal event.
An activity is a physically identifiable part of a project, which consumes both time and resources. Activity is represented by an arrow in a network diagram. The head of an arrow represents the start of activity and the tail of arrow represents its end. Activity description and its estimated completion time are written along the arrow.

What is Central Limit Theorem and Critical Path?

It is a numerical technique used in projects in which time cannot be estimated accurately such as research and development projects. It is an event-oriented network. Cost is assumed to be directly proportional to time.
Three time estimates are made in PERT.
1. Optimistic time (to): This is the minimum possible time in which an activity can be completed under the most ideal conditions.
2. Pessimistic time (tp): This is the maximum time required to complete an activity under the worst possible conditions.
3. Most likely time (tm): This is the time required to complete an activity under normal working conditions. It's value lies between to and tp It is near to the expected time.

How to Calculate Expected Time of Activity i-j?

Expected Time of Activity i-j calculator uses Duration of i-j = Earliest Occurrence Time of j-Earliest Occurrence Time of i to calculate the Duration of i-j, The Expected Time of Activity i-j formula is defined as the duration of completion of the activity i-j. An event is told to occur when all the activities leading to it are completed. Duration of i-j is denoted by t_ij symbol.

How to calculate Expected Time of Activity i-j using this online calculator? To use this online calculator for Expected Time of Activity i-j, enter Earliest Occurrence Time of j (TE^j) & Earliest Occurrence Time of i (TEⁱ) and hit the calculate button. Here is how the Expected Time of Activity i-j calculation can be explained with given input values -> 5.8E-5 = 2073600-1641600.

FAQ

What is Expected Time of Activity i-j?

The Expected Time of Activity i-j formula is defined as the duration of completion of the activity i-j. An event is told to occur when all the activities leading to it are completed and is represented as t_ij = TE^j-TEⁱ or Duration of i-j = Earliest Occurrence Time of j-Earliest Occurrence Time of i. The Earliest Occurrence Time of j is the earliest expected occurrence of event j when we consider activity i-j & The Earliest Occurrence Time of i is the earliest expected occurrence of time of event i, when we consider an activity i-j.

How to calculate Expected Time of Activity i-j?

The Expected Time of Activity i-j formula is defined as the duration of completion of the activity i-j. An event is told to occur when all the activities leading to it are completed is calculated using Duration of i-j = Earliest Occurrence Time of j-Earliest Occurrence Time of i. To calculate Expected Time of Activity i-j, you need Earliest Occurrence Time of j (TE^j) & Earliest Occurrence Time of i (TEⁱ). With our tool, you need to enter the respective value for Earliest Occurrence Time of j & Earliest Occurrence Time of i and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
