In practical people activity (in economy, control, projection of constructive and so on) there are often cases when you have to chose one solution from several. Inherently arises the task to find the best solution. Most of solutions in persons life and organisations are done in series. It means, that they can make the last solution at any moment or suspend it for later time, in the hope of better times. Part of consistent statistical solutions shows not clear events in the future and limited plausibility of our observations. Dynamic programming is simple way for optimizing consistent solutions. Dynamic programming is applied when specific problems arise, such as development of specific algorithms. There are analyzed two types of tasks in this work: one-off consistent solution and multifold consistent solutions. There are two appointed tasks, one is engineering type (technological process braking), other economic type (purchase of flat).
