Purpose – The purpose of the paper is to develop a conceptual framework that integrates the technology and commercial issues early at the design stage to minimize warranty costs in the most effective and efficient manner and also to develop a model for optimization of warranty with specific focus on reliability and warranty policies. Design/methodology/approach – The critical issues in warranty...

An effective warranty servicing strategy should be made considering both warranty cost and product availability. Based on the two-dimensional free repair warranty, a strategy combining the imperfect preventive maintenance and minimal repair is proposed where the imperfect preventive maintenances are implemented in a special subregion of the warranty and all other failures are repaired minimally...

A resource-efficient approach to making inferences about the distributional properties of the failure times in a competing risks setting is presented. Efficiency is gained by observing recurrences of the compet- ing risks over a random monitoring period. The resulting model is called the recurrent competing risks model (RCRM) and is coupled with two repair strategies whenever the system fails. ...

Background and Objectives: A blood distribution network orchestrates distribution of safe blood products to hospitals. Blood shortage and blood wastage are two important factors which may affect efficiency of blood distribution network. Service delivery time is another factor that refers to the time interval between blood request by a hospital and transfusing it to the patient....

This study makes a first effort to understand the factors affecting customers' decisions to invoke warranties, and to distinguish this behavior from the factors affecting customer perceptions of service quality. The study context is GTE's introduction of a warranty program as part of a telecommunications repair service for small business customers. The results suggest that customer perceptions ...

abstract recent interest in describing the spatial distribution patterns of weeds through using interpolation methods has increased to estimate weed seedling density from spatially refferenced data and evaluation of applicable to site-specific weed management. in this research, a multi layer perceptron neural network (mlpnn) model was developed to predict the spatial distribution of h. glaucum ...

one of the most crucial elements of each country is electricity distribution networks (edn). awareness of accidents in edn could be very important in the conservation and utilization of them. the accurate and periodic inspections can provide a good service to subscribers. the goal of this project is to fabricate a quad rotor, which can do an accurate and a periodic inspection. the design and im...
