Abstract
This study addresses the problem of designing a display and control console layout under ergonomic principles via a mathematical approach. An integer programming model is established with objective functions comprising four ergonomic principles for designing the display and control console. Unlike the traditional design methods that consider equal-area devices, the new method addresses the general ergonomic console layout problem with unequal-area components. The presented approach evaluates the console in its entirety. Due to the NP-hardness of the problem, a modified multiobjective particle swarm algorithm is proposed. Compared with the manually layout console of the electric locomotive HXD3D, our proposed model achieves better results. The layout of most of the devices can embody ergonomic principles. It is convenient for designers that the proposed method can effectively produce many good layout schemes and evaluate the layout from an ergonomic perspective.

Summary
A display and control console is the main approach for human-machine communication. Its layout has a significant effect on the health of operators and the performance of the system. The problem considered in this paper is a general ergonomic display and control console layout problem with unequal-area components. The assignment of devices and displays on a console is based on four ergonomic principles They are the principle of importance, the principle of frequency of use, the principle of functional similarity and the principle of relevance. FOUR ERGONOMIC PRINCIPLES There are four main ergonomic principles involved in the console layout problem [20], [21] CL The evaluation value of the console according to the principle of functional similarity, that is, the sum of the evaluation values of all device pairs according to the principle of functional similarity
