Purpose – The purpose of this paper is fourfold: to provide an overview of the alternative simplified credit (ASC) and a basic understanding of how it works; to provide a brief history of the research and experimentation credit as a whole and its evolution; to emphasize the importance of this...

Purpose – The purpose of this study is to introduce the concept of social welfare chain and address the challenges in decision making through the development of an optimal planning model for a nongovernmental organization (NGO). The distinctive properties of the social welfare chain and its...

Purpose – The purpose of this paper is to solve commitment problem of generating units in thermal power plants and to find the optimal dispatches of the committed units. Design/methodology/approach – The unit commitment (UC) problem has been solved in two stages. In the first stage, the...

Purpose – Although the mean‐variance portfolio selection model has been investigated in the literature, the difficulty associated with the application of the model when dealing with large‐scale problems is limited. The aim of this paper is to close the gap by using the quadratic risk...

Purpose – This paper aims to summarize the results of an empirical project to understand the perceptions of consumers of the future high end products in the USA. This project was a precursor of a larger global project on the topic. Design/methodology/approach – The approach utilizes the...

Purpose – The quality and efficiency of design and design services is declining. The authors propose that the problem is a systems delivery problem and not a technical competence issue. The purpose of this paper is to use a recently developed best value delivery methodology originally created...

Purpose – The purpose of this paper is to present a procedure for finding the efficient frontier, i.e. a non‐decreasing curve representing the set of Pareto‐optimal or non‐dominated portfolios, when the standard Markowitz' classical mean‐variance model is enriched with additional...
