The invention relates to a simulator and can be used in occupational selection and labor safety management systems.

The aim of the invention is to improve the accuracy of the device with increasing reliability of the assessment of the stability of the man-machine system.

FIG. 1 shows a block diagram of the device; in fig. 2 dependence of the trophic function of the rate of change in the cost of labor protection depending on the source of the resource; in fig. 3 - possible dependences of the change in the number of employees on accidents and occupational diseases during a certain time.

The device consists of block 1 displaying information of block 2 summation, switch 3, block 4 multiplication, block 5 installation numerical and, block 0 subtraction, block 7 setting the rate of change in costs, block 8 setting the current resource, block 9 setting the source resource, block 10 setting profit unit, cost installation unit 11, power supply source 12, engine 3, risk factor installation unit 14, operator console 15

Information display unit 1 is a laser system of type L M4100 / 1-5.

Blocks 2 and 6 are made on operational amplifiers.

The dynamics of change in a person with a computer machine (FMS) can be described by two states I - the absence of catastrophic leaps such as accidents and occupational diseases and II - the presence of these leaps.

The amount of enterprise resource determines the material approach to labor protection. The more a system has a large resource, the more material resources can be spent on solving technical issues of labor protection and thereby reducing the incidence of catastrophic jumps in the FMS. However, between the material resources invested in labor protection and the likelihood of an accident occurring is a very complicated relationship. Therefore, it is not always the investment that leads to the desired result. With an abundance of resource i, the rate of its consumption is always limited. In this case, there is a unique position in the system where it is always stable. However, the nature of the tendency towards this equilibrium can be different (Fig. 2). The ego is determined by the speed of resource arrival in the medium. If adeptive nor.TL pkoke and the rate of admission

resource is large, then any imbalance is quickly eliminated without much fluctuation in the number of accidents. If adaptability is low, and the rate of resource flow is low, then imbalance is eliminated slowly with fluctuations in numbers.

The device works as follows

0 By turning the scale of the lagometer in block 1 a constant value is set at a certain angle, which characterizes the degree of risk of work in this enterprise. Using the switch by

5 connecting one or another functional resistor of the console 15, one or another function is simulated (Fig. 1)

In blocks 5. I, 9. 10 and 11 exhibit specific parameter values, which

0 characterize the initial values of these parameters of the enterprise at a given time.

To simulate the evolution of the system, the engine 13 is turned on, which

5 synchronously moves the variable resistor engines on the remote control 15. which simulate changes in labor protection costs and changes in the enterprise resource

At the first input of the lagometer in block 1

0 enters the value from block 2 to the second input from switch 3.

The angle of rotation of the arrow in the lagometer in block 1 is proportional to the ratio of the parameter value from switch 3 to the value

5 parameters from block 2.

The behavior of the arrow over a certain period of time allows one to model the behavior of a certain type of SMM (Fig. 2).

0This device allows you to increase

the reliability of assessing the sustainability of SMM to catastrophic jumps, based on an integrated approach. This minimizes the cost of labor protection at maximum

5 control effect

In this case, the device allows: to predict the behavior of the SMM from the position of labor protection, to solve optimized tasks, to investigate the behavior of the system

0 with various parameters of the enterprise and disturbing influences, produce a quantitative and qualitative assessment of the functioning of the SMM from the position of labor protection
