Purpose – Human capital strategies are frequently canvassed in corporate boardrooms and executive suites but are not effectively implemented. This paper aims to identify core measures that senior management can use to increase the effectiveness of their investment in their people and improve...

Purpose – The use of modern portfolio theory (MPT) in the construction real estate portfolios has two serious limitations when used in an ex ante framework: the intertemporal instability of the portfolio weights; and the sharp deterioration in performance of the optimal portfolios outside the...

Purpose – To develop a new theory of portfolio and risk based on incremental entropy and Markowitz's theory. Design/methodology/approach – Replacing arithmetic, the mean return adopted by M.H. Markowitz, with geometric mean return as a criterion for assessing a portfolio, one gets...

Purpose – The aim of the paper is the fine‐tuning of proportional integral derivative (PID) controllers under model parameter uncertainties (noise). Design/methodology/approach – The fine‐tuning of PID controllers achieved using the Taguchi method following the steps given: selection of...

Purpose – To develop a new theory of portfolio and risk based on incremental entropy and Markowitz's theory. Design/methodology/approach – Replacing arithmetic, the mean return adopted by M.H. Markowitz, with geometric mean return as a criterion for assessing a portfolio, one gets...

When, in a supply chain, a supplier and a buyer have the choice of transaction form to do business, the equilibrium transaction form which emerges is much more constrained than previously envisaged in literature. In this paper, two forms of long-term supply contracts and procurement in the spot...

Purpose – The paper describes the methods of manufacturing process optimization, using Taguchi experimental design methods with historical process data, collected during normal production. Design/methodology/approach – The objectives are achieved with two separate techniques: the...

The success of business process re‐engineering (BPR) is dependent on the use of data‐driven methods that provide cost‐effective and optimal solutions. Today's business managers are inundated with methodologies and tools that claim to provide sustaining process improvement results....

In the existing BPR methodologies there exists a big division in business analysis techniques due to the black and white approach used in most cases. In some of them, cost is the central issue, in others generic management or the successful use of IT. As a result business analysis techniques are...
