Preventive Replacement Decisions for Dragline Components Using Reliability Analysis

analysis of ruin probability for insurance companies using markov chain

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...

Gamma process model for reliability analysis and replacement of aging structural components

The time-dependent reliability analysis to model age-related deterioration is necessary to support strategic planning and optimization of civil engineering infrastructure systems. The paper presents a stochastic gamma process model to account for temporal variability associated with a deterioration process and its impact on the optimal age of replacement. The proposed method is more versatile t...

Reliability analysis of mechanical components

During the design stage, realistic life time predictions for components help to reduce test cycles and allow for an optimization with respect to both production and repair costs (see e.g. Schuëller et al. 1996). Accurate predictions of the mean life time and its standard deviation can be obtained from a fracture mechanics approach that takes the uncertainties in the material parameters into acc...

Replacement Decisions for Evolving Software

E-type software, software implementing real world computer applications, must be continually evolved to maintain user satisfaction, generally over several years and releases. It is likely that the responsible organisation will, sooner or later, consider its replacement through redevelopment or acquisition. This paper discusses elements believed to be relevant in the context of replacement decis...
