8 AI MAGAZINE One of the central challenges in computational sustainability is how to allocate resources in order to optimize long-term objectives. An archetypal application is conservation planning: managers recommend patches of land in order to achieve long-term conservation of biodiversity. In this and similar applications, we typically have to make decisions over time: financial resources (...

In this paper we introduce a class of Markov decision processes that arise as a natural model for many renewable resource allocation problems. Upon extending results from the inventory control literature, we prove that they admit a closed form solution and we show how to exploit this structure to speed up its computation. We consider the application of the proposed framework to several problems...

— Road traffic is a problem which is increasing in cities with large population. Unrelated to this fact the number of portable and wearable devices has also been increasing throughout the population of most countries. With this advent, the capacity to monitor and register data about people habits and locations as well as more complex data such as intensity and strength of movements has created ...

Sustainability is a wide concept that contains other concepts such as social responsibility and has been investigated with concepts such as competition sustainability, reporting sustainability, and social sustainability. The present study aims to investigate the role of social interest rate risk management (SIRRM) in the relationship between sustainability performance and investment ef...

Maritime transport and ports are among the most important linkages between global economies, handling more than 90% of internationally traded goods. Economic importance maritime imposes significant implications on social environmental performance port regions. The paper aims to create composite indices as relevant, scientific-based tools used in comparing monitoring various aspects sustainabili...

Companies today face the challenge of adopting proper supply chain sustainability (SCS) strategies and practices to respond effectively to emerging global sustainability initiatives. Business sustainability has become a strategic imperative, with a focus on both financial and non-financial sustainability performance, which creates shared value for all stakeholders. This paper examines the integ...

In this study a simulation-optimization model is developed for deriving operation rule-curves in drought ‎periods. To each reservoir, two rule-curves with adjustable monthly levels are introduced dividing the ‎reservoir capacity into three zones between the normal water level and minimum operation level. To each ‎zone of a reservoir and for each month of the year a hedging coefficient is introd...

Good implementation of corporate governance principles is considered as an important component for stability and soundness of a financial institution. An extensive body of literature has reviewed the effects of corporate governance on the performance of corporations. The majority of these studies have found more corporate values for implementing the principles. Therefore, the assessment of comp...
