In this paper, we characterize the humanitarian objectives of emergency resource allocation and distribution in disaster response operations. We formulate the humanitarian principles as three objective functions, i.e., lifesaving utility, delay cost and fairness. An integrated multi-objective...

Project risk management, as a subjective and dynamic decision method of avoiding project risk, plays an important role in selecting appropriate control measures (i.e. measure set) to handle multiple emerging risks (i.e. risk set). This paper focuses on the multi-risk control problem under the...

As more supply chains are becoming dependent upon suppliers, an interruption of supply networks can obstruct the functionality of the entire supply chain. The purpose of this paper is to present what we believe is a useful way to think about the number of suppliers needed in the presence of...
