Abstract The crossover among two or more types of diffusive processes represents a vibrant theme in nonequilibrium statistical physics. In this work we propose models to generate crossovers different Levy processes: the first model change gradually order derivative Laplacian term diffusion equation, whereas second one consider combination fractional-derivative terms characterized by coefficient...

Business process monitoring provides well established means to track the history and state of business processes and to evaluate their performance. However, common techniques and systems lack support of monitoring processes and their interactions with partners, particularly if such processes are not automated or only few events can be detected, rather than a complete log. In this paper, we pres...

This paper describes all the manufacturing cell monitoring process particularities, and its several features. It is also done a brief presentation of the data structure used to monitor the manufacturing cell status, and it is explained its achievement and its philosophy by a complete flowchart. 1.Introduction and brief description The monitoring process of the manufacturing cell deals with the ...

ion led to users interpreting the representations in varied ways [87]. Furthermore, Kilander and Lönnqvist [75] warned that the “monitoring of mechanical activities such as network or server performance easily runs the risk of being monotonous” and Pedersen and Sokola reported that they soon grew tired of the highly abstract representations used in Aroma. It is interesting that they put some of...

Process safety and environment pollution demands are continuously increasing in the process industry. Apart from that, requirements regarding final product quality and production efficiency are higher and higher [1]. This can be achieved by applying advanced process monitoring and control techniques. Process control is heavily dependent on the quality of the data, so it is crucial to measure as...

in this paper, first the available single charting methods, which have been proposed to detect simultaneous shifts in a single process mean and variance, are reviewed. then, by designing proper simulation studies these methods are evaluated in terms of in-control and out-ofcontrol average run length criteria (arl). the results of these simulation experiments show that the ewma and ewms methods ...
