The risk factors of international engineering projects are systematically analyzed from multiple dimension features of the projects. The muhilayer evaluation index system for the international engineering project risk assessment is proposed and constructed, which consists of 8 I-grade indexes and 24 II-grade indexes as policy risk, market risk, resource risk, and technical scheme risk, schedule risk, funding risk, personnel risk and management risk. And then the self-evaluation and benchmarking evaluation methods are applied to evaluate the international engineering project risk, and established the corresponding mathematical models. Finally, a project evaluation example is given to illustrate the applicability and effectiveness of the mathematical models.展开更多

To obtain real-time and comprehensive state of project, we use grid management to divide the project supervision grid in three levels: stage, objective, and milestone. Then, a detailed supervision mechanism is designed to help supervisors measure the project situation in real time. This mechanism checks that if the project objectives(such as schedule, cost, quality, and safety) in every supervision grid cell are under the healthy limits, any project deviation can be identified as soon as possible.A schedule objective is selected as an example to illustrate the method used to calculate the healthy limit.展开更多

A steam cracking project is selected and analyzed, from which typical SC characteristics in international engineering projects in the area of petrochemical industry are summarized. The MINLP model is therefore developed and applied to projects with detailed data. The optimization results are analyzed and compared by the MINLP model, indicating that they are appropriate to SC management practice in engineering projects, and are consistent with the optimal priceeffective strategy in procurement. As a result, the model could provide useful guidance to SC optimization of international engineering projects in petrochemical industry, and improve SC management by selecting more reliable and qualified partner enterprises in SC for the project.展开更多
