We consider a solvable task to minimize losses for waiting the processing on a machine with changeover of a batch of different-type workpieces of any physical nature (metal, wood, plastic, stone, etc.). The peculiarity of this machine is that during the transition to processing a workpiece of another type than the previous workpiece type, it is required a machine changeover during certain period of time, which is usually dependent on the last and the next operations.

     This task can be solved numerically by using the new science-intensive network technology called "Information technology of automation of control of discrete technological and information processes (in short — IT AC DTIP)", because optimizable process has all necessary properties for that. This process is discrete and is classified as a time-limited process. Its elements in terms of DTIP are:

• workpieces in a batch — demands;
• a machine with changeover — a device of service.
