The paper considers setting the goal of creating the optimal order portfolio, based on the concept of integrity of a machine-building company. It has been proposed to consider the concept of corporate integrity as a composite controlled parameter which forms the machine- building company-specific competence and technological uniqueness, production capacity and the level of customer value of products, determining the economic efficiency of the company operation. The study of the typology of subject-object relations has identified the operational, financial-industrial and speculative approaches of owners to company management, matching their priorities. Within the group of private owners, the following classes of them have been singled out: 1) industrial investor (efficient owner); 2) financial investor; 3) speculator; 4) inefficient owner. For all types of owners, the sets of priorities and the approaches to integrity management have been identified and presented, on the basis of which the owners take administrative decisions on adaptation and transformation of corporate integrity. From the standpoint of the operational approach to corporate integrity, taken by a machine-building company owner, the author’s classification of tasks has been developed, aimed at creating the optimal order portfolio. The proposed classification serves as the basis for further formalized setting of the full range of optimization tasks aimed at formation of the order portfolio for a machine-building company and elaboration of algorithms for their solution
