In this study, a new warranty service strategy is proposed and analyzed. This strategy adds the renewing free-replacement warranty to a non-repairable product sold under the rebate warranty policy. According to the renewing free-replacement warranty, the seller (manufacturer) is responsible for replacing all failed product during the warranty period, and the warranty begins anew with each repla...

Along with increasing the warranty period for complex systems, reducing the warranty servicing costs has become an issue of great importance to the manufacturers. One possible way to reduce the expected warranty servicing cost is by making sound decision on the product warranty and maintenance strategies. Therefore, warranties (basic warranty and extended warranty) and maintenance (corrective a...

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...

Mugwort and ragweed pollens have been considered as important respiratory allergens in Korea. These two pollens are abundant in the air of Seoul from August through October. Many ragweed-sensitive patients have shown concurrent sensitivities to mugwort pollen. However the antigenic relationship between these two pollens has not been clarified. To observe the cross-reactivity between them, we de...

This paper describes a database of 11 dependency treebanks which were unified by means of a two-dimensional graph format. The format was evaluated with respect to storage-complexity on the one hand, and efficiency of data access on the other hand. An example of how the treebanks can be integrated within a unique interface is given by means of the DTDB interface.

Phloem exudate collected from hybrid poplar (Populus trichocarpa x Populus deltoides) was estimated to have more than 100 proteins, of which 48 were identified using LC-MS/MS. Comparative two-dimensional gel electrophoresis demonstrated that two phloem exudate proteins were significantly (P<0.05) upregulated 24 h after leaf wounding. These were identified as pop3/SP1 and a thaumatin-like protei...

They can also be caused by two types of human 7 factors. On the one hand, consumers might claim warranty due to misuse and/or failures caused by other human 8 factors. Such claims might account for more than 10% of all rep...
