A method for adjusting work items of crew members in a mobile cabin

Abstract

The invention relates to a method for adjusting the working items of a passenger in a movable bin. The method for adjusting the working items of the passenger in the movable bin comprises the steps that firstly, a passenger task-network model based on execution channels is established, wherein the task-network model is used for forming a relevant network graph on the execution channels according to the time and execution logic for tasks of the passenger; secondly, the working parameters of a system model are determined, wherein the working parameters include the time parameters and the resource parameters, the time parameters include the response time of the passenger and the movement time of the passenger, and the resource parameters are used for representing the mental load values of the passenger and the probability distribution of the mental load values of the passenger; thirdly, the mental load average value of the execution channels of the passenger is obtained through calculation according to the passenger task-network model determined in the first step and the working parameters determined in the second step; fourthly, the overall mental load of the passenger is obtained through calculation; fifthly, the sequence of the working items of the passenger is adjusted according to the overall metal load of the passenger, so that misoperation caused by a mental overload is avoided.

Description

technical field [0001] The method relates to the field of mental load measurement, in particular to the field of adjusting work items according to the mental load of occupants in a mobile cabin. Background technique [0002] The process of processing operation information by the occupants of the mobile cabin is a mental labor process, and the occupants need to pay a certain amount of mental resources and produce a certain degree of mental load. The mental load of the occupant has a great influence on the working efficiency of the system, the comfort level of the occupant, and the safety and health. For example, when the amount of information presented in the system is high, occupants become stressed due to "brain overload". At this time, it is often difficult for the occupants to complete the perception and processing of all the operation information at the same time, resulting in the omission or wrong perception of the perceived information, and the control or decision-mak...

AI Technical Summary

Problems solved by technology

At present, the commonly used evaluation methods of occupant mental load include subjective evaluation method, main task measurement method, auxiliary task measurement method, etc., but there are some problems in these methods that limit their further application in complex man-machine systems, mainly in: (1 ) mixed with the subjective preference of the decision maker, the system error is relatively large, and it is impossible to quantitatively evaluate the mental load of the occupants

(2) There is a lack of research on the mechanism of mental load, and it is impossible to clarify the type of resource system that causes the crew's mental load to be too high

(3) Lack of model support, it is impossible to evaluate the mental load of the occupant based on the task

(4) It is impossible to clearly describe the mental load of the crew during the full-task operation, and the evaluation lacks real-time performance

(5) It is impossible to predict and evaluate the occupant's mental load in the system design stage, and the application has limitations

[0005] The problems of this method are: 1) The determination of the behavior sequence based on the 28 behavioral elements does not reflect the relevance and temporal and logical interrelationships among the behavioral elements of the work task, that is, the task-network model is not given; 2) The resource parameters conform to a certain probability distribution, and this method does not study the resource parameters; 3) The corresponding analysis of the cognitive channel is not carried out; 4) Although the behavior is extracted according to the 4 channels, the execution channels are not given. In terms of mental load, it is impossible to accurately find out the deep-seated reasons for the excessive mental load of the occupants, and it is impossible to provide feasible suggestions for the operation of the occupants
