Abstract Project-chain describes the complex relationship between associative projects in engineering. Risk management in engineering project-chain is more difficult than in single engineering. Based on the resource sharing relationship between projects, the risks transferring fluctuation to the final goal are defined as risk elements, and the quantitative mathematical expressions of risk elements are also given. Based on the analogy with work breakdown structure (WBS), the model of risk breakdown structure is proposed. By using moment function to calculate the value characteristics, the final risk degree of project-chain is calculated. Finally, the model is applied in a funds allocation case.

1. Introduction Risk management plays an important role in engineering project management and the transmission effect widely exists in projects. Many scholars did a lot of research on risk management, Li [1-3] considered the transmission effect in generalized projects and proposed the risk elements transmission theory. The theory gave the quantitative study on risk elements and paid more attention on calculating the final risk elements probability distribution. However,...
