Cell formation problem in Cellular Manufacturing System (CMS) design has derived the attention of researchers for more than three decades. However, use of sequence data for cell formation has been the least investigated area. Sequence data provides valuable information about the flow patterns of various jobs in a manufacturing system. This paper presents a new mathematical model to solve a cell...

It is shown that the class of conditionally Gaussian processes with independent increments is stable under marginalisation and conditioning. Moreover, in general such processes can be represented as integrals of a time changed Brownian motion where the time change and the integrand are jointly independent of the Brownian motion. Examples are given.

More than new algorithms, proofs, or technologies, it is the emergence of definitions that has changed the landscape of cryptography. We describe how definitions work in modern cryptography, giving a number of examples, and we provide observations, opinions, and suggestions about the art and science of crafting them.

In this paper, the variational iteration method for solving nth-order fuzzy integro-differential equations (nth-FIDE) is proposed. In fact the problem is changed to the system of ordinary fuzzy integrodifferential equations and then fuzzy solution of nth-FIDE is obtained. Some examples show the efficiency of the proposed method.

The business segment of Japanese companies such as Toshiba changed drastically for the last several years. This means that companies should change their culture and need new product development process applying information technologies. This paper presents examples of design technologies that realize the innovative product development process in Toshiba focused on an electromechanical product d...

In this paper we obtain explicit formulas for distributions of extrema of exponentials of time-changed Brownian motions with drift which generalize normal inverse Gaussian processes. The generalization is made by multiplying the normal inverse Gaussian process by a constant. The results are established with respect to the equivalent martingale measure. As examples of applications, problems of p...
