The purpose of this chapter is to introduce and discuss organizational process modeling (OPM). This is a modeling approach developed for use in the design of IT systems. It is one part of a broader process approach described by Warboys, et al. [1]. The associated ProcessWeb technology, with its executable process modeling language (PML), provides the technological infrastructure. The whole set ...

employees anxiety and worry about their work life and involvement for a longtime hours, pave the way for permanent engagement in their work, in a way that continuity of these situations will have a positive and negative outcomes. present research is aimed at explaining strange captivation of nurses to their work in the form of workaholism. data of this applied research was collected through sur...

application of agent based model in simulation of stakeholder’s behavior is slightly a new method for modeling of complicated systems that include autonomous agents interacting with each other. recent numerical achievements have made the applications of agent based models possible in various fields. these applications range from modeling of human progress and destruction of past civilizations t...

In this study, based on data from instrumentation Kaboodval earth dam, pore pressure, stresses and the meeting of the dam construction period compared with the values ​​of numerical analysis. For this purpose, during the construction of the dam using Mohr-Coulomb model behavior, the softening, hardening model has been analyzed and pore pressure, stresses in the body and its meeting with instrum...

determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. in this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. the critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. in a...

parachor based expressions (basic and mechanistic) are often used to model the experimentally observed pressure dependence of interfacial tension (ift) behaviors of complex supercritical carbon dioxide (sc-co2) and crude oil mixtures at elevated temperatures. however, such modeling requires various input data (e.g. compositions and densities of the equilibrium liquid and vapor phases, and molec...

The objective of this study was to model seasonal behavior of broiler price in Iran that can be used to forecast the monthly broiler prices. In this context, the periodic autoregressive (PAR), the seasonal integrated models, and the Box-Jenkins (SARIMA) models were used as the primary nominates for the forecasting model. It was shown that the PAR (q) model could not be considered as an appropri...
