Cost-benefit analysis on remote maintenance for industrial robot

Abstract

The maintenance of industrial robots can be divided into two types: onsite maintenance and remote maintenance, each of which has its advantages and disadvantages. Firstly, the two types of maintenance modes, cost and benefit are analyzed and compared. While cost of on-site maintenance mainly includes downtime loss, maintenance cost and expert cost, downtime loss includes production loss and manpower waste, maintenance cost includes testing cost and material cost, and expert cost includes travel expense and labor cost. Cost of remote maintenance also includes downtime loss and maintenance cost, but does not include expert cost. Downtime loss and maintenance cost of remote maintenance is same as that of onsite maintenance, but the value is different. Then, cost-benefit method is used to analyze and establish cost-benefit model of two maintenance modes. Finally, an automobile manufacturing enterprise is taken as an example, and the cost and benefit of on-site maintenance and remote maintenance is analyzed and calculated to apply and verify the proposed method. The method proposed in this paper can provide help for the maintenance mode selection of industrial robots.
