The operability of production job is described from two aspects of operation process and cognitive psychological process through combining literature research with production practice. Based on the analysis of operation behavior,the evaluation method framework model of production job operability is established by considering time pressure. And the operational evaluation index and its calculation method are developed from six aspects: job space evaluation,job pose evaluation,action feature evaluation,information acquisition process evaluation,information processing evaluation and information output. The case study shows that the method is feasible and can be applied to many different fields when we select different weights.
