Computer based management systems (CMS) are characterized by a number of attributes: functional structure, data basis, technical tools, as well as the organization and implementation of design and efficiency. Each system operates in a particular environment: managerial levels, socio-economic systems, industrial sectors. This paper discusses the functional hierarchy of CMS for different managerial levels (e.g., technological unit or process, individual plant-enterprise, corporation sector, region, nation, international grouping), as well as the evaluation of the data base, the hardware architecture, and efficiency. Most of these problems are considered with respect to plan-oriented and market-oriented economies
