8. The method of claim 7, wherein analyzing the health operating condition of the cigarette making machine by comparing the evaluation index of the comprehensive efficiency of the cigarette making machine with the evaluation standard of the comprehensive efficiency comprises:
(a) if the scores of all components of the comprehensive efficiency evaluation index of the rolling and connecting equipment are larger than the target value, the historical average value and the last scoring result, the current equipment management level reaches the target of the preset equipment management level, the comprehensive efficiency of the rolling and connecting equipment is in a very good state, an enterprise should continue to keep the current rolling and connecting equipment management measures, and meanwhile, the current target value is adjusted or kept according to the actual management condition of the rolling and connecting equipment;
(b) when the scores of all components of the comprehensive efficiency evaluation index of the rolling equipment are greater than the historical average value and the last scoring result, and the recent scoring results of the rolling equipment are greater than the historical average value, the comprehensive efficiency control level of the enterprise rolling equipment is in a continuous stable good state;
(c) when the scores of all components of the comprehensive efficiency evaluation index of the rolling equipment are all larger than the historical average value but are all or partially lower than the last scoring result, the comprehensive efficiency of the rolling equipment in the statistical period is in a continuous good but unstable state, and the efficiency management of the rolling equipment is kept;
(d) when the score parts of all components of the rolling equipment are larger than the historical average value or the last scoring result, the comprehensive efficiency of the rolling equipment in the statistical period is in an unstable step-back state. Deeply analyzing the components with the corresponding scores lower than the historical average value by the enterprise, and taking corresponding improvement measures according to the analysis result;
(e) when the scores of all components of the rolling equipment are smaller than the historical average value but part of the scores are larger than the last scoring result, the fact that the equipment management level in the statistical period is in a seriously unstable local good state is shown, and an enterprise needs to take improvement measures immediately;
(f) when the recent scoring result of the rolling-connection equipment is smaller than the historical average value and the last scoring result, the level of the long-term management and control of the enterprise equipment is in a seriously unstable step-out state, the enterprise needs to pay serious attention, and improvement measures are immediately taken.
