Nowadays, offering extended warranty is considered as a lucrative source of income from the perspective of the after-sale service providers. Meanwhile, the main concern is presence or absence of base warranty and strategies adopted by the manufacturer during this period. Moreover, extended warranty structure must be responsive and customer oriented, which not only control the services cost but ...

In this paper a stochastic model for a single unit repairable system with Preventive Maintenance (PM) under warranty is analyzed in details by using supplementary variable technique. The cost of repair during warranty is born by the manufacturers, but warranty does not apply to product failure due to user-induced damage such as cracked screen or cracked casing, accident, misuse, physical damage...

This paper addresses the effect of twodimensional warranty policies on the procedure for forecasting the cost of unreliability. Automotive warranties are characterized by age or time in service and vehicle usage mileage. This paper presents a model where the usage time is a primary variable and the mileage accumulation is estimated from field return data. At each time interval the probability o...

This paper considers estimation of normal mean ? when the variance is unknown, using the LINEX loss function. The unique Bayes estimate of ? is obtained when the precision parameter has an Inverse Gaussian prior density

In this paper a redundancy allocation problem is studied where for the first time the supplier selection is taken into consideration and redundant components are provided from appropriate suppliers with the most suitable offers such as discount on buying price of components, warranty length for components, things like that, so that the system reliability, profit and the warranty length proposed...

The temperature dependence of the viscosity inorganic glasses in glass transition region is successfully described by Williams--Landel--Ferry (WLF) equation. For studied glasses, value f_g=1/C 1 weakly depends on nature glasses. There a linear correlation between delta T g and . From data parameters WLF equation C 2 , we calculated as well relaxation time structure tau at under study. Keywords:...
