Guan, Jinlan; Ou, Jiequan; Hu, Changhua An optimized model for pipeline laying. (Chinese. English summary) Zbl 1289.90098 J. Foshan Univ., Nat. Sci. 30, No. 6, 33-36 (2012). Summary: It is necessary to work out a least-cost model for pipeline laying from the perspective of decreasing costs. We put forward a design for such a model on the basis of analyzing the distance between a refinery and the railway, the distance between a refinery and another, the cost of pipeline laying and the sharing of a pipeline.
