Risk Decision-Making of Multiobjective Chaos Search in Construction Projects considering Loss Level and Probability Level

Table 1

Comparison of models with and without correlation.

Multiobjective risk decision model		Model 1	Model 2
Same point		1. Decision variables and risk assessment values; 2. Minimize risk control cost targets; 3. Models are integers
Differences	Losses are nonadditive	No	Yes
	Different types of risk losses	But the risks	Related risks
