A large number of products are now being sold with long-term warranty policies. This is mainly due to fierce competition in the market and customer demand.

Cognitive radio (CR) provides an effective solution to meet the huge bandwidth requirements in intelligent transportation systems (ITS), which enables secondary users (SUs) access idle spectrum of primary (PUs). However, high mobility and real-time service result additional transmission collisions interference, degrades rate quality (QoS) ITS. This paper proposes a algorithm (Feilin) based on f...

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...

We approximate the distribution of total expenditure of a retail company over warranty claims incurred in a fixed period [0, T ], say the following quarter. We consider two kinds of warranty policies, namely, the non-renewing free replacement warranty policy and the non-renewing pro-rata warranty policy. Our approximation holds under modest assumptions on the distribution of the sales process o...

Furthermore, based on the behavior of customers, it is assumed that increasing the warranty period to earn the trust of more customers leads to more sales until the market is sat...
