Abstract

Abstract:

To ensure the efficient and stable operation of a whole production line, the reliability evaluation of assembly line is studied. In this paper, the LEC method is used to evaluate the human factor reliability of the assembly line production efficiency and its stability. To reduce the subjectivity of the LEC method and make the evaluation more objective, this paper used the objective reliability and error analysis (CREAM) to calculate objectively the rate of human error, while carrying out the evaluation of the possibility L of work suspension accidents. At the same time, the two indexes of E and C were modified and improved. The proposed evaluation model is applied and verified to the automobile assembly line. The result shows that it has certain feasibility and reference value.

Key words: assembly line, human error rate, improved the LEC method
