This study continues the analysis of problems of optimization techniques using the example of staged evaporation of steam in the boiler drum to reduce the concentration of impurities in the steam from the boiler. The described techniques use mathematical packages and spreadsheets to solve the paradoxical problems of optimization.

New solution of the transportation problem - see Figs 7.5 (Finding with AlvaroDíaz).

See the picture and the Mathcad Prime 3.1 and Mathcad 15 files in attach.

It is the Fig for new edition of the book!
