Today, the art and skill of management in organizations is moving towards changing into the art of "knowledge management"; and, leadership means providing suitable conditions and grounds in producing valuable knowledge via human force thought, and performing this task in a way that would encourage individuals in undertaking personal responsibility. The leadership factor plays a key role in successful implementation of knowledge management in enterprises and organizations; thus, in the present research, the authors have studied the relationship between knowledge management and leadership style as well as defining empowerment leadership style in knowledge management. The statistical population considered in this research consists of employees of Iran Export Credit Insurance Institute. The present research is applied in term of goal and description and correlation in terms of nature and methodology adoption. To study the relationship between variables, the regression analysis based on SPSS software, factorial analysis, modeling structural equations based on variance by using PLS software has been used.  In line with research hypotheses, the correlation coefficients showed the positive and significant relationship between transformational and transactional leadership with knowledge management; and on Laissez-Faire leadership style, no significant relationship was confirmed between this variable and knowledge management variable.

Therefore, by measuring the performance of hospitals based on lean principles, and by identification of critical factors that function as obstacles to the execution of this approach and also by rating them, health centers can be led toward application of the principles of lean thinking. This study has aimed to develop Goodson’s rapid performance assessment for health centers based on lean principles to measure their efficiency.

This relationship is called a profile. Parametric models, such as linear models, may be used to model profiles. However, in practical applications due to the complexity of many processes it is not usually possible to model a process using parametric models.In these cases, non-parametric methods are used to model the processes. One important and applicable non- parametric method used to model complicated profiles is wavelet transformation. Use of wavelet transformation requires estimation of the in control profile in phase I. Classical estimators are usually used in phase I to estimate the in control profile, using wavelet transformation. However,the presence of outliers in data in phase I may affects classical estimators.In this research a robust estimator of the in control profile based on clustering is proposed which is insensitive to the presence of outliers. As well as estimating the in control profile in phase I it is of interest to determine the change point of the process in phase II. In this work a procedure for estimating the change point of complicated profiles in phase II is also introduced. This suggested method does not require normality assumption of the error terms. Aggregation of the proposed robust estimator with the change point detection method results a procedure for detecting the change point.
