A State-Dependent Wear Model With an Application to Marine Engine Cylinder Liners

Summary: [This abstract is based on the authors' abstract.] A model is proposed to describe the wear process of the cylinder liners of heavy-duty marine diesel engines. The likelihood function of the data from staggered inspections of the engines is obtained using time and space discretization. Model parameters and reliability characteristics of the liners are estimated and wear growth during future inspection intervals is predicted. A maintenance scenario demonstrates the need for accurate modeling of the wear process in the planning of maintenance activities.
