One of the most useful and effective methods with an extensive application in companies with the purpose of examining the quality of the raw material in addition to final products, is acceptance sampling plans. The inspection process is assumed to be free of errors in most of the acceptance sampling plans. However, this assumption may not be true. In this research, an optimization model for acceptance sampling plan is developed based on Bayesian inferences in the presence of inspection errors. An economical model is designed which involves two types of inspection errors and investigates the impact of these errors on the acceptance-sampling plan. Furthermore, the sensitivity analysis is carried out to analyze the behavior of optimal solution. The numerical studies indicate that increasing the inspection error leads to decrease the sample size and acceptance number. Manuscript profile

The present study aims to investigate the relationship between organizational culture, knowledge sharing and innovation. The research population consists of all knowledge workers in the South Oil Products Refining and Distribution Company, from which 190 people were selected as samples using the non-random targeted sampling method. The research data was collected by distributing questionnaires among samples. After collecting data, the distribution of the data related to the variables was examined using the Kolmogorov–Smirnov test; then, the Pearson’s correlation coefficient and structural equation modeling were used to test the research hypotheses. The results of this study show that there is a significant relationship between variables of organizational culture, knowledge sharing and organizational innovation. Also, the results of examining the components of organizational culture demonstrated that adhocracy and clan cultures have positive effects on other variables while hierarchy and market cultures negatively affect the dependent variables.

The present study aimed to assess the effects of human resource empowerment on the organizational effectiveness. The nature of the study was descriptive-survey research method with functional purpose of correlation. The study population consisted of 700 staff of Fars Electricity Distribution Company, among whom 155 were determined by Cochran, who were selected by cluster randomization considering the coefficient. Measurement tools in this study included: Spritzer and Mishra empowerment questionnaire (1997), and Parsons organizational effectiveness questionnaire (1998). Despite the standardization, validity and reliability of the tools were re-evaluated that resulted in coefficients of 0.95, and 0.89, respectively. Inferential statistics, used to test the hypothesis, showed that empowerment (sense of competence, self-determination, impact, meaning, and trust) of employees have a significant relationship with their organizational effectiveness. And, empowerment predicted organizational effectiveness. The findings also showed that the most important role among empowerment dimensions in predicting effectiveness is associated with components of competence, trust and effectiveness.
