Structural Sustainability - Heuristic Approach

Environmental Sustainability —A Consumption Approach

Surely one of the greatest achievements of the current phase of globalization has been the spurt of economic growth in countries that were desperately poor just a few decades ago and some of which, even now, carry huge burdens of poverty. This spurt in economic growth and the consumption growth that accompanied it have lifted hundreds of millions out of poverty and, concurrently, provided a gli...

Heuristic Approach to Organic Chemistry

An important question in organic chemistry is how does a chemist synthesize chemicals in the most efficient way beginning with chemicals readily available. These problems are known as synthesis problems. Currently, methods based on databases (Chen, 2006) and methods related to quantum mechanics (Jorgensen, 1998) are used frequently to solve this problem. When solving synthesis problems by hand,...

Portfolio Selection: A Heuristic Approach

Heuristic Approach to Train Rescheduling

Starting from the defined network topology and the timetable assigned beforehand, the paper considers a train rescheduling in respond to disturbances that have occurred. Assuming that the train trips are jobs, which require the elements of infrastructure – resources, it was done by the mapping of the initial problem into a special case of job shop scheduling problem. In order to solve the given...

Heuristic approach for forecast scheduling

Forecast Scheduling (FS) is a scheduling concept that utilizes rate prediction along the users’ trajectories in order to optimize the scheduler allocation. The rate prediction is based on Signal to Interference plus Noise Ratio (SINR) or rate maps provided by a Radio Environment Map (REM). The FS has been formulated as a convex optimization problem namely the maximization of an α−fair utility f...
