Model of Forecasting Water Shortage Degree

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

178: Forecasting the Shortage of Neurosurgeons in Iran Using a System Dynamics Model Approach

CONTEXT Shortage of physicians particularly in specialty levels is considered as an important issue in Iran health system. Thus, in an uncertain environment, long-term planning is required for health professionals as a basic priority on a national scale. AIMS This study aimed to estimate the number of required neurosurgeons using system dynamic modeling. SETTING AND DESIGN System dynamic mo...

Forecasting the absolute and relative shortage of physicians in Japan using a system dynamics model approach

BACKGROUND In Japan, a shortage of physicians, who serve a key role in healthcare provision, has been pointed out as a major medical issue. The healthcare workforce policy planner should consider future dynamic changes in physician numbers. The purpose of this study was to propose a physician supply forecasting methodology by applying system dynamics modeling to estimate future absolute and rel...

biological control of the codling moth by trichogramma embryophagum based on degree-hours forecasting model

the codling moth, cydia pomonella, is the most important pest insect in apple orchards. efficacy of a native strain of the egg parasitoid wasp, trichogramma embryophagum, was statistically compared with chemical control and check treatments in an apple orchard. the best times for releasing the parasitoid wasps were determined by using a forecasting model based on estimation of growing degree ho...
