Here is how the Crashing equation looks like.

55 = \frac{1400 - 300}{129620 - 129600}

55 = \frac{1400 - 300}{129620s - 129600s}

55 = \frac{1400 - 300}{129620 - 129600}

Crashing Solution

Follow our step by step solution on how to calculate Crashing?

FIRST Step Consider the formula

CS = \frac{CC - NC}{NT - CT}

Next Step Substitute values of Variables

∴

CS = \frac{1400 - 300}{129620s - 129600s}

Next Step Prepare to Evaluate

∴

CS = \frac{1400 - 300}{129620 - 129600}

LAST Step Evaluate

∴

CS = 55

Variables

Cost Slope

The Cost Slope is defined as the increase in the cost of the activity per unit decrease in the time.

Symbol: CS

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Cost Slope

Crash Cost

Crash Cost is the cost associated when the project is completed with the crash time of the project.

Symbol: CC

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Crash Cost

Normal Cost

The Normal Cost is the cost associated when the project is completed within the normal time.

Symbol: NC

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Normal Cost

Normal Time

Normal time is the amount of time initially planned to complete the activity.

Symbol: NT

Measurement: TimeUnit: s

Note: Value should be greater than 0.

Formulas to find Normal Time

Crash Time

Crash time is the amount of time that activity will take if the additional resources are expended.

Symbol: CT

Measurement: TimeUnit: s

Note: Value should be greater than 0.

How to Evaluate Crashing?

Crashing evaluator uses Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time) to evaluate the Cost Slope, Crashing usually result in an increase in the cost of those activities that are constructed under the crash programme. Cost Slope is denoted by CS symbol.

How to evaluate Crashing using this online evaluator? To use this online evaluator for Crashing, enter Crash Cost (CC), Normal Cost (NC), Normal Time (NT) & Crash Time (CT) and hit the calculate button.

FAQs on Crashing

What is the formula to find Crashing?

The formula of Crashing is expressed as Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time). Here is an example- 55 = (1400-300)/(129620-129600).

How to calculate Crashing?

With Crash Cost (CC), Normal Cost (NC), Normal Time (NT) & Crash Time (CT) we can find Crashing using the formula - Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time).
