Warranty Period: What Do We Expect From SPECT? As single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) has reached scientific and clinical maturity, we have grown to expect that the results of this test when negative, reliably predicts an excellent patient outcome. Typically, less than 1% of patients with a normal study will have a “hard” cardiac event, defined ...

This paper deals with the development of a model to predict the products’ terminal call rate (TCR) during the warranty period. TCR represents a key information for a quality management department to reserve the necessary funds for product repair during the warranty period. TCR prediction is often carried out by parametric models such as Poisson processes, ARIMA models and maximum likelihood est...

Wind speed and wind direction indicator in turbine is a very important component the whole power generation system. Inaccurate or incorrect sensor signals will not only make inefficient, but also affect safe operation of life other components. After warranty period, after plant takes over maintenance, maintenance demand above sensors be greatly increased. In this project, numerical simulation u...

In this paper, a replacement-repair model is developed to study a warranty servicing policy for a class of multi-state deteriorating and repairable products, based on a computer simulation analysis. In each working state there is a determined probability for transition to each of the subsequent states, given that it has made a transition out of that state. There are two parameters that determin...

With the help of advanced digital technologies, product managers can use monitored mission cycles to sustain reliability. In this study, a random warranty model and replacement next (RRN) are designed through-life reliability with cycles. The warranty, called two-stage two-dimensional free repair (2DFRW), be carried out during stage. ‘whichever occurs first last’ is used distinguish coverage ra...

This article presents a review of the issues associated with a manufacturer’s pricing strategies in a twoechelon supply chain that comprises one manufacturer and two competing retailers, with warranty period-dependent demands. The manufacturer, as a Stackelberg leader, specifies wholesale prices to two competing retailers who face warranty period-dependent demand and have different sales costs....

The environmental sustainability and business benefits of end-of-life products have led to worldwide growth in the remanufacturing market. However, customers are often sceptical about quality durability remanufactured products. To ensure a risk-free customer experience, dealers carry out some upgrading actions on most critical components offer reasonable warranty period at time resale. It is cr...

employing remanufactured and refurbished products are among the new strategies that companies used to raise their profits as well as protects environment. although used product equipment gives an opportunity to purchase latest technology, customers are doubtful about quality and reliability of these products. because of limitation that developing countries faces in buying new products, some cou...

This study examines pricing decisions by considering two manufacturers’ warranty and bundling strategies using spatial competition in a duopolistic market. With the development of advanced technology evolving societal needs, manufacturers now sell product with its complement—a warranty—using either bundled base or an unbundled extended strategy. To investigate impact strategy on models, we deve...
