چکیده

An understanding of how both psychological and environmental factors mutually constrain skilled behavior is required to effectively support human activity. As a step toward meeting this need, a process model of skilled human interaction with a dynamic and uncertain environment is presented. The model was able to mimic human behavior in a laboratory task requiring oneand two-person crews to direct the activities of a fleet of agents to locate and process valued objects in a simulated world. Reflective of the need to explicitly consider both environmental and cognitive influences on behavior, the process model is a pair of’ highly interactive components that together mimic the behavior of the human-environment system. One component is a representation of the external environment as a dynamically changing set of opportunities for action. This environmental component is based on the ecological viewpoint that relations indicating the match between the human’s capacity for action, and actions made available by the environmental structure, should serve as primitives in the description of the environment for the skilled performer. The second component is a dynamic representation of skilled human decisionmaking and planning behavior within the environment so described. Modeling both human and environment in an integrated fashion allowed for a description of behavior as being mutually influenced by the external environmental structure and an internal priority structure over available actions. Sensitivity to environmental structure ensured that action selection opportunistically exploited the dynamic possibilities for action afforded by the external situation, whereas the priority structure ensured that action selection was also consistent with task goals. The process model is an expression of a general theory of skilled interaction assuming that perception and action mechanisms sensitive to environmental constraints are responsible for generating much of behavior, and where the need for additional cognitive processing of internal representations (e.& problem-space search, multiple option comparison) may result from environmental designs that do not adequately support the perceptual guidance of activity.

Enhancement of Robust Tracking Performance via Switching Supervisory Adaptive Control

When the process is highly uncertain, even linear minimum phase systems must sacrifice desirable feedback control benefits to avoid an excessive ‘cost of feedback’, while preserving the robust stability. In this paper, the problem of supervisory based switching Quantitative Feedback Theory (QFT) control is proposed for the control of highly uncertain plants. According to this strategy, the unce...

A New Stock Model for Option Pricing in Uncertain Environment

The option-pricing problem is always an important part in modern finance. Assuming that the stock diffusion is a constant, some literature has introduced many stock models and given corresponding option pricing formulas within the framework of the uncertainty theory. In this paper, we propose a new stock model with uncertain stock diffusion for uncertain markets. Some option pricing formulas on...
