- Gorelov M. Hierarchical games under uncertainty
Hierarchical game of two players is considered. It is supposed that the leader has incomplete information about follower’s interests. The maximum guaranteed payoff of the leader is calculated. An alternative definition of the maximum guaranteed payoff is suggested, which is shown to be equivalent to the classical one. It is used to reduce the problem of maximum guaranteed payoff simple transformations of predicate calculus expressions.
- Zorkaltsev V. Of entering into the feasible solutions region the interior point method
The interior point algorithm for a linear programming problem is considered. This algorithm consists of two stages. On the first stage we enter to the region of feasible solutions given the specified constraints. The second stage is optimization over the feasible region. The entering into the feasible region is represented as an extended linear programming problem by adding only one new variable. The main goal of the paper is to provide a theoretical justification of the process of entering into the feasible region under assumption of non-degeneracy of the extended problem.
- Belov M., Savich A., Garichev S., Kondratyev V., Lytov D. Plm-systems framework
Standard enterprise architectures supported by standard methodologies provide support methods for organization and coordination of engineering projects of enterprise as a whole as well as enterprise entities or enterprise subsystems [11, 17]. In [7] “Operation Systems Framework” approach is suggested as a basis for enterprise engineering.
This approach sets a compact support engineering representation of enterprise operational organization and can be used with the necessary localization to the different entities and operation subsystems of the company. For example in [5] the engineering of “Enterprise Management System” and Management Systems Framework are considered. In this article engineering of “Product Lifecycle Management” (PLM) and the PLM-systems Framework are considered.
- Zhilyakova L. Resource networks with the capacity limitations on attractor-vertices. formal characteristics
We study the resource redistribution in networks with capacity limitations on so-called attractor-vertices. The stability of the processes for any total amount of resource in such networks is proved. We formulate the criterion of secondary attractivity, and find vectors of limit flow and limit state, formula for the second threshold value of resource ÒII. As indirect results we get several additional characteristics of networks with limitations and without them.
- Avdeeva Z., Kovriga S. Cognitive-map-based approach to statement of system development control problem based for the strategy monitoring
We propose a novel approach to control problems of system development in changing external environment. To find a solution of such problems a modification of SWOT-analysis on cognitive-map model is proposed. The proposed approach is illustrated by two real-life examples: 1) an enterprise with ecologically dangerous production and 2) socio-economical city development.
- Vil’ms M., Mandel A., Barladyan I., Tokmakova A. Supply chain management local model for unrliable suppliers
A supply chain management mathematical model for an isolated warehouse with two suppliers of different reliability is considered. Optimal inventory control strategy synthesis algorithm is constructed. The transfer to stationary strategies is investigated. We developed C++ software package to simulate algorithm for two different probabilistic distributions of demand: discrete Gauss-like and another one, discrete too, close to uniform. These examples are used to investigate the optimal stationary strategy parameters and costs dependency of econometrical attributes (among these – discount factor).
- Karpov V. Models of social behaviour in the group robotics
We discuss general principles of interaction in groups of robots based on models of social behavior. A number of the models and methods implementing various forms of social organization in groups of robots on the basis of community typification are offered. We consider such fundamental mechanisms as coalition formation, language communication and task distribution in collectives. Implementation of psychophysiological features on the basis of the mechanism of emotions and temperament lies at the heart of the model of an individual capable to socialization.
- Tuphanov I., Scherbatyuk À. Some marine trial results of centralized control system for marine robot group
A problem of underwater environment parameters measurement in the local area by using a group of marine robots is described in the paper. A centralized method for operation planning of robot group is used in the work. A replanning during the operation is considered for the case when the number of robots in a group changes. The results of marine trials using marine robotic complex MARK including AUV and ASV are given.
