lecturer: assistant professor hu shaolong
about the lecturer:
dr. hu shaolong graduated from the school of economics and management, tongji university, majoring in management science and engineering. he focuses on emergency logistics research, including emergency material allocation, supplier selection, and post-disaster distribution. he has published many high-leveled papers as the first author and corresponding author including "transportation research part b", "omega", "system engineering theory and practice" and so on.
about the lecture:
although natural disasters are difficult to predict accurately, a large amount of historical data shows that the occurrence of some disasters is mostly seasonal. for example, typhoons and floods occur more often than in the rainy season, while ice disasters only occur in winter. at the same time, there are uncertainties in the location and intensity of their occurrence. the demand for emergency supplies is dynamic and uncertain, that is, there are uncertainties in demand in different time periods. existing research on emergency material reserves only pays attention to the uncertainty of disaster information such as location and intensity, and uses methods such as two-stage stochastic planning or robust optimization to determine the optimal storage location and inventory, enterprise selection and other storage decisions. ignoring the time of occurrence of natural disasters and making reserve decisions based on static and uncertain demand can easily cause material reserves to be unbalanced. that is, in certain periods, there are too many reserves in certain areas, resulting in materials that are idle for a long time, high storage costs, and materials expired. therefore, considering the dynamic and uncertain demand, the study of the dynamic reserve of emergency supplies has important theoretical and practical value. this lecture will focus on this topic.
