Usage of industrial networks of Internet with net-centric control is the driving trend of the future material manufacturing of goods and services. The bright future of this approach is out of doubt provided these complex net-centric systems will use adaptive approach to planning of manufacturing scenarios and function with high reliability. The issue here is that such systems are characterized by complex multi-parameter operability modes controlled by a large number of criteria. The paper considers an approach to providing reliable management of complicated IoT systems. This is achieved by solving multi-criteria tasks over many processes of various physical nature. Corresponding methods of hierarchical decomposition of multi-criteria tasks, levels of the process of multi-criteria optimization, specifics of aggregation levels and the master equation (algorithm) of the optimization process are described.
