As one of the lean manufacturing tools Just in Time (JIT) is based on the "zero stock and defect" principle. While JIT has a positive impact on the general productivity of companies, there are findings of the detrimental effects of JIT on the environment. As an emerging research area, "green ergonomics" suggests that the effects of every human activity on the environment must be considered to protect nature and human beings. Thus, the results of JIT activities conflict with the aims of green ergonomics. This paper investigates ways to overcome this conflict. To that end, the measures to be taken to make JIT compatible with the green ergonomics concept were determined and analyzed. While determining the measures, a relationship is established between the measures and the principles of green ergonomics. In the analysis stage, the interval valued type-2 fuzzy extension of Analytical Hierarchy Process with group decision-making technique was employed. This paper contributes to literature in two ways. In practical terms, it provides guidance for the companies that want to conduct JIT activities without harming the environment. In theoretical terms, it handles and analyzes green ergonomics principles and JIT concept in an integrated manner.
