...Shen Cheng; B.S. Dhillon Purpose The purpose of this paper is to study reliability, availability, and mean time to failure of a repairable robot‐safety system composed of n robots, m safety units, and a perfect switch. Design/methodology/approach Generalized expressions for system state...

... in the decision‐making process. An example is presented as a case‐study from manufacturing of industrial robots. Design/methodology/approach The paper is mainly based on a case‐study performed at a large multi‐national company aiming to explore the usefulness of case‐based experience reuse in production...

...Balbir S. Dhillon; Shen Cheng Purpose The purpose of this paper is to study reliability, availability, and mean time to failure of a repairable robot‐safety system composed of (n−1) standby robots, a safety unit, and a switch. Design/methodology/approach Generalized expressions...

...B.S. Dhillon; Zhijian Li This paper presents reliability and availability analyses of a robot‐safety system having one robot and n‐redundant safety units with common‐cause failures. The system failure rates and the partially failed system repair rates are assumed constant, and the failed...

...B.S. Dhillon; A.R.M. Fashandi; K.L. Liu This paper presents a review of published literature on robot reliability and safety. The literature is classified into three main categories: robot safety; robot reliability; and miscellaneous. Robot safety is further categorized into six classifications...
