Most leading organizations, in all sectors of industry, commerce and government are dependent upon ERP for their organizational survival. Yet despite the importance of the decision to adopt ERP and its impact on the entire firm’s performance the IT literature has been in the large part silent on the nature of the ERP investment decision. This study is the first of its kind to determine the pref...

We propose a Decision-Guided Energy Investment (DGEI) Framework to optimize power, heating, and cooling capacity. The DGEI framework is designed to support energy managers to (1) use the analytical and graphical methodology to determine the best investment option that satisfies the designed evaluation parameters, such as return on investment (ROI) and greenhouse gas (GHG) emissions; (2) develop...

Abstract: Financial investment has become an important issue, there are many trading strategies and parameters based on quantitative models, this paper use neural network algorithm to optimization strategy parameters, various combinations of optimization strategies, as well as the evolution of new strategies to generate better returns. The empirical results show that this method has a stable an...

Papers published in this report series are preliminary versions of journal articles and not for quotations. Abstract This paper extends the real options literature by discussing an investment problem, where a firm has to determine optimal investment timing and optimal capacity choice at the same time under conditions of irreversible investment expenditures and uncertainty in future demand. Afte...

System-initiated digressive proposals may be used to introduce new and unexpected information into automated telephone services. These digressions may be viewed as particularly pronounced forms of unsolicited interruptions as they contain information not directly related to the caller’s intended activity. In human–human conversation, interruptions are considered to be speech acts which intrinsi...

The real options approach to corporate investment decision making recognizes a firm can delay an investment decision and wait for more information concerning project cash-flows. The well known models of McDonald and Siegel (1986) and Dixit and Pindyck (1994) value the investment decision as a perpetual American call option on the project value. The former specifies the equilibrium return via CA...

The protection of assets, including IT resources, intellectual property and business processes, against security attacks has become a challenging task for organizations. From an economic perspective, rms need to minimize the probability of a successful security incident or attack while staying within the boundaries of their information security budget in order to optimize their investment strat...

This paper documents a controlled experiment on the effect of adding a graphical model to a fictitious corporate security decision problem. The control group (N=44) saw a textual description, and the treatment group (N=41) was presented a graphical representation using the ArchiMate security extension modeling language in addition to the textual description. Besides the security investment deci...

Predictability of financial time series (FTS) is a well-known dilemma. A typical approach to this problem is to apply a regression model, built on the historical data and then further extend it into the future. If however the goal is to support or even make investment decisions, regression-based FTS predictions are inappropriate as on top of being uncertain and unnecessarily complex, they requi...
