In the current unstable business environment, it is necessary to change the organization's strategy in a way that organizations can adapt to the new conditions. To cope with these changes, the organizations need features called dynamic capabilities. In multi-business organizations, portfolio strategies are formulated, implemented and controlled for the strategic management of the diverse busine...

The purpose of the present study was the simulation of climate change effects on groundwater resources in Iran by using the dynamic systems approach. The approach was performed through system dynamics modeling process including problem explanation, system description, model development, model testing, and the use of the model for policy analysis. The impact of the application of various exogeno...

In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...

As part of the development of equipment and innovative technology for the process flow-sheet, a study on the selection of good resin for uranium uptake is ongoing. Both static and dynamic column equilibrium testing upon synthetic and Gattar pregnant leach solutions (PLS) were carried out to estimate the change of total capacity and breakthrough capacity of the commercial macroporous anion excha...

the dynamic facility layout problem (dflp) is the problem of finding positions of departments onthe plant floor for multiple periods (material flows between departments change during the planning horizon)such that departments do not overlap, and the sum of the material handling and rearrangement costs isminimized. in this paper a new optimization algorithm inspired from colonizing weeds, invasi...

Purpose: examining that the postmodern library as a fluid, ambiguous, and “quantum” organization how could be assessed. Methodology: conceptual analysis Findings: Today’s academic libraries face unprecedented challenges developed by the "dynamic of perpetual change". The present environment of unpredictable and perpetual change is not a phase or a period of transition but the new reality. In ...

Data envelopment analysis (DEA) measures the relative efficiency of decision making units (DMUs) with multiple inputs and multiple outputs. DEA-based Malmquist productivity index measures the productivity change over time. We propose a dynamic DEA model involving network structure in each period within the framework a DEA. We have previously published the network DEA (NDEA) and the dynamic DEA ...

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
