Levels Of Control

Abstract In a distributed, object-oriented, hierarchical shop control system, there are many ways of organizing the interactions between supervisory controllers and subordinate controllers. Depending on what model of job control is used, objects will be allocated differently among the levels of control, and the interactions between controllers will vary considerably. This paper describes five models of job control that are equally functional, but use different paradigms for managing jobs. Although each is attempting to serve the same purpose in the same context, the five ways of viewing the system lead to distinct implementations that cannot interoperate. This demonstrates the importance of specifying the control model when designing an object-oriented manufacturing system.

System Input

Subsumption control architecture is an control architecture based on parallel system. Input of information of sensors is directly connected through modules in the control system, and further the decision making is connected to actuators. Automated Guided Vehicle or AGV is an automated component within integrated manufacturing system. In this article, this control architecture will be designed and implemented to an AGV. Commands are designed based on Object-Oriented technology. The commands are arranged in subsumption, where a command higher subsumed other command of its lower level. GPFO (Greater Priority First Out) technique is implemed for executing the commands by using multi-threading. Experimentation is performed to have the characteristics of commands being executed. This work introduce our effort to design an operating system for an AGV.

Role Based

In this paper the possibility of representing of some types of role-based access control models by object-oriented discretionary access control model is considered. The role-based security models with taxonomic hierarchy are considered. The permissions of the role-based access control model are represented as a set of pairs of object and access right. A hierarchy of classes of the object-oriented HRU model, based on the role-based access control policy, is constructed. Commands of the object-oriented HRU model, corresponding to the reassignment of roles in the original role-based model, are described.

Intrinsic Muscles

The reciprocal interaction between the accommodation and pupil control systems of the human eye is examined from a theoretical point of view. The system, which is responsible for maintaining pupil diameter at a value which is a compromise between conflicting requirements, is represented by a control model, and is considered in terms of the concept of a performance index.
