RT Journal Article SR Electronic A1 Muškát, Peter A1 Urban, František A1 Bereznai, Jozef A1 Závodný, Zdenko T1 Comparison of Linear and Nonlinear Optimization Methods of Heating Plant Operation JF Manufacturing Technology Journal YR 2016 VO 16 IS 3 SP 569 OP 574 DO 10.21062/ujep/x.2016/a/1213-2489/MT/16/3/569 UL https://journalmt.com/artkey/mft-201603-0016.php AB The article presents comparison of optimization methods applied to operation of the heating plant. Optimizing problems are possible to solve with using of methods of the linear programming (LP) or nonlinear programming (NLP). In the paper method of differential addition (LP, NLP), method of characteristics (LP), simplex method (LP), method of Lagrange multipliers (LP, NLP) and method of hyperplane in n - dimensional space (LP, NLP) are presented from point of view of requirements for designing and modifications of the program, requirements on system memory and computation time, comparison of the optimizing methods for loading of the thermal power machines and devices.
