This paper presents the effects of a free-repair warranty on the periodic replacement policy in discrete time process. Consider a repairable product that should be operating at the time over an indefinitely long operation cycle n (     , 2 , 1 n ); under the discrete-time periodic replacement policy, a product is preventively replaced at pre-specified operation cycles    , 3 , 2 , N N N ...

The paper is concerned with estimating the cost of production and warranty in context a new product development project. All possible variants trade-off between costs are sought within company’s resources requirements for A company its projects can be specified terms variables constraints that constitute systems approach problem related to optimization. This described form constraint satisfacti...

We consider the problem faced by a company selling a product with warranty and under partial information about the product reliability. The product can fail from multiple failure types, each of which is associated with an inherently different repair cost. If the product fails within the warranty duration, then the company is required to pay the repair cost. The company does not know the probabi...

Cost assessment related to age of multiple components is discussed. We use definitions of equivalent ages in multi-dimensional life to illustrate how cost characteristics should be fairly assessed. Pricing of used items with residual value and assigning warranty for used items as a function of item’s age are the subjects of our study. Numeric examples based on correlated Bivariate normal distri...

In this paper we consider the problem of minimizing the costs of outsourcing warranty repairs when failed items are dynamically routed to one of several service vendors. In our model, the manufacturer incurs a repair cost each time an item needs repair and also incurs a goodwill cost while an item is awaiting and undergoing repair. For a large manufacturer with annual warranty costs in the tens...

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...

This paper makes a link between opportunistic maintenance literature and warranty analysis of a power plant. A new plant warranty maintenance tasks are observed over a two year period. The main aim is to see how opportunistic maintenance could be incorporated when the warranty period has elapsed. The paper examine the warranty period maintenance task list and propose adequate methods for assess...
