ERP value has been long assumed to be static in traditional evaluations. This study proposes a stochastic simulation model of ERP business value, which bridges the gap between ERP business value theories and modern finance evaluation approaches. By incorporating life cycle, the critical characteristic of ERP business value, uncertainty is explicitly accounted for in the model. We quantitatively justify...
This paper evaluates ERP investment under uncertainty using the Real Options for modeling. We utilize a quantitative model and real option concept to evaluate the investment rule for the ERP investment. We use PDE to obtain the optimal threshold ratio of revenue and cost. Finally, we determine the threshold value by incorporating the illustrative parameter of ERP investments.
The Photovoltaic Arrays has a best optimal operating point. When operating at this location, the array will be most efficient in the production of electricity. However, the optimal operating point can be compromised by the strength of solar radiation, angle, environment and fluctuations in workload. Due to the constant changes in these conditions, it has become very difficult to locate the optimal...
In this paper, a novel image authentication scheme is proposed based on Sudoku puzzle. The goal of this scheme is to verify the integrity of an image against network attackers with malice. Sudoku is a logic-based combinatorial number-placement puzzle. Sudoku rule as its name means that the digits must be single. Here, it is used to be the verification code, instead of material watermarks, for the...
