| 抄録: | Modeling, optimization and control of complex systems is now commonly regarded as a necessity, in view both of current needs and opportunities. The needs stem from a desire to better use the existing assets and resources and the opportunities are due to well developed and still fast improving computing and communication facilities. Large systems arise in numerous fields of production, environmental or military activities and usually are structured in a natural way as consisting of a number of interconnected or otherwise interacting subsystems. Decentralized or hierarchical structures with suitable decision mechanisms and some sort of coordination are then required to optimize or control such systems. Coordination of actions of a number of agents or subsystems is a general concept. This paper presents and discusses various, vastly different, concepts of coordination, amenable to practical applications; namely iterative coordination and periodic coordination. It is shown that iterative coordination may be realized in a centralized or in a distributed form, and that it may be concerned with solving a large optimization problem or with a control of a complex system, like a computer network, operating in steady state conditions. Periodic coordination may be used for control of large dynamical systems as a means to suitably shape local decentralized decision mechanisms. The examples of structures employing such coordination, described in this paper are: flood management in a multiple reservoir system and command/control system for missile defense of an important object. The paper is concluded with a short discussion of the issues concerning the case when a large computational problem or a system to be controlled is unstructured, i.e. is not a priori partitioned into a number of subproblems or subsystems. |
