The Production Switching Heuristic (PSH) developed by
Mellichamp and Love (1978) has been suggested as a more
realistic, practical and intuitively appealing approach to
aggregate production planning (APP). In this research, PSH
has been modified to present a more sophisticated open grid
search procedure for solving the APP problem. The...
Carbon dioxide (CO2) as a greenhouse gas has been increasing in recent decades. Because an elevated atmospheric CO2 influences insect physiology and behaviour, we hypothesize that pheromone-mediated communication in the moth is affected by an increased CO2 level. We test the behavioural responses of male Helicoverpa armigera to sex pheromone...
