Objective: To assess the risk of cost control of chemical projects based on principal component analysis. Methods: The principal component analysis method is used to analyze the risk points of cost control and to assess the risk of chemical projects in combination with the features of the projects themselves. Results: The principal component analysis is used to assess the risk of cost control of chemical projects and conclude in the study that the key points on the cost control of chemical projects are as follows: first, strictly control the cost of materials; second, control the cost of power and fuel. Conclusion: It’s concluded that the principal component analysis is an effective method on evaluating the risk of cost control of chemical projects with some reasonable suggestions proposed.
