Abstract

According to the inherent characteristics of long-distance oil and gas pipelines, the optimization of emergency resources allocation can be implemented to maximize the utilization of pipeline emergency resources under a certain cost of emergency investment. We built an improved solution of a multiple knapsack problem in a greedy algorithm, proposed maximizing Emergency Resources Factor (ERF) as the greedy strategy, and established the optimization model of emergency resources allocation. This model innovatively combines factors such as the centrality of rescue points, the risk of pipe sections, and the necessity of emergency resources. The results show that, compared to a conventional resource allocation in a fixed proportion, an optimized allocation can reduce resource shortage and redundancy by 2.660% and 1.051%, respectively. Therefore, this model can be used to control the initialization of resource allocation in emergency rescue points of long-distance oil and gas pipelines.

1.1 BackgroundPipeline transport takes over most of the transportation of oil and gas
In topography and geological statistics, pipe sections are most distributed in plains, followed by piedmontplains, hills and lowmountains, and others are channel and mudflat, etc

Summary

Introduction

Pipeline transport takes over most of the transportation of oil and gas. It plays an important role in economic development, social stability and the national defense construction. In the event of accidents on main oil and gas pipeline, emergency resources, such as personnel and materials, should be delivered from the nearest rescue point in time to minimize direct and indirect losses. Under the presumption that the rescue points along the pipeline have been established and the total cost of the emergency resources is fixed, the allocation of various emergency resources of each rescue point, which ensures the emergency resources requirements for accidents at any location of the pipeline and minimize the repairing time of emergency resources allocation, is about to be established
