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...

I this paper, we study a firm that faces demand from two sources: demand for new items and demand to replace failed items under warranty. We model this setting as a multiperiod single-product inventory problem where the demands for new items in different periods are independent and the demands for replacing failed items depend on the number and ages of the items under warranty. We consider back...

We consider the problem of outsourcing warranty repairs to outside vendors when items have priorities in service. The manufacturer has a contract with a fixed number of repair vendors. The manufacturer pays a fixed fee for each repair done by a vendor which is independent of the repair type and priority class but depends on the vendor. There are a fixed number of items under warranty, and each ...

As a result of these changes and developments in technology, which often come unexpectedly, consumers are frequently tempted to update their devices to the very latest model. The result is that the life cycle of a produc...

When a repairable product is sold with a free replacement warranty, the manufacturer has the option of rectifying a failure by either repairing the failed item or replacing it with a new one. In this paper, repairs are assumed to be minimal in the sense that they leave the product in exactly the same condition it was in prior to failure. We discuss the form of the optimal repair}replace strateg...

Thermal sprayed HVOF WC-based cermet coatings containing various metallic binders have been used in several different applications industries that require abrasive sliding wear resistance, such as hydraulic pistons, shafts or bearings. The potential dangerousness and cost increase off cobalt-based binders, underlining the challenge reducing reliance on this metal binder resistant coatings. pres...

INTRODUCTION Musculoskeletal injuries may have a significant economic impact on the film and motion picture (FMP) industry. However, there is currently no comprehensive data on the cost of workers' compensation (WC) claims in the FMP industry. We present the first analysis of the cost of musculoskeletal injuries in the California (CA) FMP industry. METHODS We reviewed the WC claims database o...

This study deals with a two-level supply chain consisting of one manufacturer and one retailer. We consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. The retailer receives product and conducts a 100% inspection....
