Abstract

This research aims to identify the effectiveness of the principles of lean production in reducing waste in (the Central Refineries Company / Al-Dora Refinery). The data was collected using a questionnaire form. The form was responded to by 60 employees from among those who were invited to participate, as the questionnaire included Measuring the main variables of lean production and waste, and relying on the (Spss.V.24)program in statistical analysis. Quantitative and qualitative methods were used in this analysis, such as arithmetic means and standard deviations, and testing the effect of these variables. The results of this research have shown that the dimension of organizing the work site, S5, is relatively weak compared to the rest of the dimensions of the variable, the pillars of lean production, and it needs to be re-attentioned by senior management more seriously in order to obtain the most important advantages of this pillar, which is reducing waste. There is also a significant relationship that confirms the impact of Lean production and waste in production institutions
