This paper presents an empirical investigation to study the effect of knowledge management on job satisfaction in Iranian texture industry. The proposed study of this paper designs a questionnaire and distributes it among 219 out 230 employees who work for one Iranian texture firm in province of Markazi in Iran. The study uses structural equation modeling to examine different hypotheses based on the implementation of LISREL software package. The results of our investigation indicate that knowledge management positively influences on organizational improvement, organizational learning as well as quality improvement. The results of study also indicate that while there was a negative relationship between organizational improvement and job satisfaction, quality improvement and organizational learning positively influence on job satisfaction.

Supplier selection, inventory management and optimal lot sizing has been one of the most important issues in many industries especially in production planning issues associated with texture industry. The proposed model of this paper first introduces an algorithm to choose the best supplier and it determines the optimal lot size using discount strategy. The proposed model of this paper considers different influencing factors such as location, quality of materials, cost, and mutual trust for supplier selection, determines their relative importance weights and then a discounting method is used to determine the ordering lot-size. The preliminary results indicate that the proposed model of this paper can be implemented in texture industry, very efficiently since the ordering discount policy is not sensitive to changes on inventory holding and setup expenditures.
