We obtain the strong growth rate for the sum Sn of random variables by using a Hájek-Rényi type maximal inequality. Under the same conditions as that in Fazekas and Klesov [2000. A general approach to the strong law of large numbers. Theory Probab. Appl. 45, 436-449], we get sharper results...

Spare parts generate high sales margins and improve customer loyalty by extending the useful life of base products. Forecasting and managing the spare-parts business is challenging, however, due in no small measure to short life cycles and long support life for the base products. At...

We present an application of a novel Variational Wave Acquisition Stereo System (VWASS) for the estimation of the wave surface height of oceanic sea states. Specifically, we show that VWASS video technology combined with statistical techniques based on Euler Characteristics of random fields...

In this paper, we study a two-flight model where there are two flights between two cities in a day (e.g., one departs at 9:00 am and another at 11:00 am) and booking requests in each fare class arrive according to a random process. There are three types of booking requests: the first and...

We study a manufacturing process that is quite common in semiconductor wafer fabrication. In generic terms, the job to be processed consists of J units. To process the job, a "setup" is required, followed by routine processing and testing. In principle, the entirety of the job can be set up and...

Many industries face the problem of selling a fixed stock of items over a finite horizon. These industries include airlines selling seats before planes depart, hotels renting rooms before midnight, theaters selling seats before curtain time, and retailers selling seasonal goods such as...
