Реферат The manager as a teacher: selected aspects of stimulation of scientsfsc thinking





uence are inadmissible, since they cause diverse undesirable effects associated with transition period.

If external influence is equal to zero, all SFU are deactivated, as zero external influence is corresponded by zero activation of SFU. If, after a short while there would be new external influence, the system would repeat all in a former order. Duration of the system performance cycle is also seriously affected by processes of restoration of energy potential of the actuated SFU. Every SFU, when being actuated, would spend definite (quantized) amount of energy, which is either brought in by external influence per se or is being accumulated by some subsystems of power supply of the given system. In any case, energy potential restoration also needs time, but we do not consider these processes as they associated only with the executive elements (SFU), while we only examine the processes occurring in the control blocks of the systems. Thus, the system continually performs in cycles, while accomplishing its micro cycles. In the absence of external influence or if it does not vary, the system would remain at one of its stationary levels and in the same functional condition with the same number of functioning SFU, from zero to all. In such a mode it would not have transition multi-micro-cycle (long-time repeat of the 3rd micro cycle). Every change of level of external influence causes transition processes. Transition of function to a new level would only become possible when the system is ready to do it. Such micro cycles in various systems may differ in details, but all systems without exception have the NF multi-micro-cycle. With all its advantages the NF has a very essential fault, i.e. the presence of transition processes. The intensity of transition process depends on a variety of factors. It can range from minimal to maximal, but transition processes are always present in all systems in a varying degree of intensity. They are unavoidable in essence, since NF actuates as soon as the result of action of the system is produced. It would take some time until affectors of the system feel a mismatch, until the control block makes corresponding decision, until effectors execute this decision, until the NF measures the result of action and corrects the decision and the process is repeated several times until necessary correlation "... external influence в†’ result of action ... "is achieved. Therefore, at this time there can be any unexpected nonlinear transition processes breaking normal operating mode of the system. For this reason at the time of the first "Actuation" of the system or in case of sharp loading variations it needs quite a long period of setting/adjustment. And even in the steady-state mode due to various casual fluctuations in the environment there can be a minor failure in the NF operation and minor transition processes ("noise" of the result of action of real system). The presence of transition processes i...
