Therefore, our research mainly focuses on the problems of function allocation between man and machine in man-machine systems, analyses each capability advantage of man and machine according to their respective inherent characteristics and makes a comparison between them. In view of highly uncertain characteristics of decision attribute value in the practical process, we introduce the uncertain linguistic multiple attribute decision making (ULMADM) method in the function allocation process. Meanwhile, we also use the uncertain extended weighted arithmetic averaging (UEWAA) method to determine the automation level range of the operator functions. Then, we eventually estab- lish the automation level of man-machine function allocation by using the multi-attribute decision making algorithm, which is combined by UEWAA and uncertain linguistic hybrid aggregation (ULHA) operators. Finally, an example about function allocation is given, that is, fault diagnosis in the cockpit of civil aircraft. The final result of the example demonstrates that the proposed method about function allocation is feasible and effective.展开更多

The development device uses the patient’s voluntary biomechanical signals, specifically, winks—which constitute an ability that generally remains in this kind of patients—, as interface to control the computer. A prototype based on robust and low-cost elements has been built and its performance has been validated through real trials by 16 users without previous training. The system can be optimized after a learning period in order to be adapted to every user. Also, good results were obtained in a subjective satisfaction survey that was completed by the users after carrying out the test trials.展开更多

In this paper, an intelligent decision support system, IDSS is defined as: "any interactive system that is specially desinged to improve the decision making of its user by extending the user’s cognitive decision making abilities." As a result, this view of man-machine joint cognitive system stresses the need to use computational technology to aid the user in the decision making process. And the human’s role is to achieve total system’s objectives. The paper outlines the designing procedure in successive steps. The first identifies the decision maker’s cognitive needs for decision support. The second defines the computationally realizable support functions that could be provided by IDSS. The third, the specific techniques that would best fill the decision needs are discussed. And finally, for system implementation the modern computational technology infrastructure is emphasized.展开更多
