Because of an increasing flow of data being derived from external economic environment and inner business processes, it has become vital to create an automatized tool for prescribing scenarios for most of the standardized cases occurring within the manufacturing mainframe. This work aims to study the needs of the businesses and to design a simple tool for maintaining the decision support process in obedience with the existing market demand. In the context of the paper, various approaches to demand plan establishment will be considered and further methods for its remote control will be researched. For the existing problem solved, a model of Decision Support System will be designed which will operate based on Supervisory Control Theory.
