ABSTRACT

The laying of the oil pipeline is a big project that costs lots of money. How to lay oil pipeline between oil refinery and railway is an engineering problem worthy of attention. This paper starts from studying the laying length of common and non-common pipelines between two refineries and railway, according to whether the cost of laying the shared pipeline and the non-common pipeline is the same, and whether the connection between the two refineries and the railway line are vertical or non-vertical. It is divided into four categories by establishing different cost expressions. Considering the laying of pipelines in urban areas, compensation for demolition, etc., this paper proposes a total cost model for laying oil pipelines in urban areas based on linear programming, and finds that the most cost-effective construction of pipelines is 2,827,000 yuan. Considering the actual market situation, due to the different laying costs of oil pipelines in refineries a and b, the shortest pipeline length and the total cost of laying may not be guaranteed. The planning model was optimized, and the most cost-effective cost of pipeline construction was obtained through the Lingo software. It was 2.5197 million yuan.
