PY - 2016 DA - December JF - TWMS Journal of Applied and Engineering Mathematics JO - JAEM PB - Işık University Press WT - DergiPark SN - 2146-1147 SP - 333 EP - 341 VL - 6 IS - 2 LA - en AB - The actual application for the problem of best approximation of grid function by linear splines was formulated. A mathematical model and a method for its solution were developed. Complexity of the problem was that it was multi - extremal and could not be solved analytically. The method was developed in order to solve the problem of dynamic programming scheme, which was extended by us. Given the application of the method to the problem of ow control in the pressure-regulating systems, the pipeline network for transport of substances pipelines of water, oil, gas, and etc. that minimizes the amount of substance reservoirs and reduces the discharge of sub- stance from the system. The method and the algorithm developed here may be used in computational mathematics, optimal control and regulation system, and regressive analysis. KW - grid functions KW - the best approximation KW - minimal deviation KW - linear splines KW - dynamic programming KW - optimal regulation.
