Dynamically adjustable emergency transport scheduling plan generation method

Abstract

The invention discloses a dynamically adjustable emergency transport scheduling plan generation method. The method comprises the steps of 1: uniformly dividing the whole transport scheduling time intoT cycles, and representing a cycle sequence number of a current decision with r, wherein r belongs to {1,...,T}, and an initial value of r is 1; 2: obtaining environmental information of E cycles starting from the first cycle, running an initial plan decision model, generating an E scheduling cycle-oriented initial plan, executing the plan of the first scheduling cycle, and then enabling r to beequal to r+1; 3: collecting actual execution conditions of decisions generated in the cycles from the first cycle to the (r-1)th cycle, and demand update information from the cycle r to the cycle min(r+E-1,T); 4: according to the information collected in the step 3, running an adjustment decision model, generating scheduling decision plans of multiple cycles starting from the current cycle r, butonly executing the plan belonging to the current cycle r; and 5: updating r to be equal to r+1, and if r is less than or equal to T, going to the step 3, or otherwise, ending the scheduling. The method has the advantages that emergency resource scheduling scheme plans are dynamically optimized and adjusted according to information continuous updating results.

Description

technical field [0001] The invention belongs to the field of emergency management, and in particular relates to a method for generating a dynamically adjusted emergency transportation dispatch plan. Background technique [0002] After a major natural disaster such as a strong earthquake occurs, the demand for materials at each disaster-stricken site, the number of wounded, and the number of disposals will generally increase in a blowout manner. In order to minimize the loss of life and property of the people in the disaster area, it is necessary to quickly organize emergency resource transportation and dispatch after the disaster and other disaster relief operations in order to transport all kinds of urgently needed materials to the disaster area and transfer the wounded and sick who cannot be treated on the spot. However, when organizing and dispatching these transportation activities, post-disaster rescue command decision makers not only need to consider the dynamics of fa...

Problems solved by technology

The emergency resource scheduling based on multi-period planning only considers the emergency resource scheduling plan based on the current time for a period of time in the future, and does not consider the impact of information "feedback" on the scheduling plan during the plan execution process; research on dynamic scheduling based on the idea of ​​disturbance management However, it focuses on the research of frequent emergencies under normal circumstances, and focuses on the "local adjustment" of the original plan after the occurrence of disturbance events. There are few research results on sudden major natural disasters, and most of the research on post-disaster emergency logistics The research is limited to the vehicle route planning (VRP) problem; the research on emergency resource transportation scheduling based on Bayesian decision theory, the design of Bayesian risk depends on the prior probability and the subjective consciousness and level of the researcher, and the objectivity is relatively insufficient
