In 1972, the Club of Rome’s infamous report “The Limits to Growth” (Meadows et al., 1972) presented some challenging scenarios for global sustainability, based on a system dynamics computer model to simulate the interactions of five global economic subsystems, namely: population, food...

The paper presents a comprehensive validation procedure for the passenger traffic model for Copenhagen based on external data from the Danish national travel survey and traffic counts. The model was validated for the years 2000–2004, with 2004 being of particular interest because the...

Using simulation to support making decisions imposes that models are thoroughly validated. We discuss widely adopted techniques for testing the validity of simulation results against real observations, as various techniques may be employed depending on the statistical features and the number of...

Inverse techniques for dynamic simulation models which allow determination of the time history of “inputs” needed to achieve a specified time history for a selected set of “outputs” have been receiving some attention in recent years within aerospace engineering and in other application...

A quarterly econometric model of the U.S. dairy sector has been developed for use in short-to medium-term outlook and policy analyses. Simulations of the model indicate that it performs quite well both during the estimation period and during an eight-quarter interval beyond the estimation...

Society has demanded reform in medical resident work scheduling; consequently, hospitals are implementing changes having organizational, clinical, financial, social, emotional, and educational consequences for physician training and patient care. We report the use of simulation modeling as an...

Operational validation of a linear programming model of a dairy farm is done on the basis of representative results from reality. The model will be used to determine the effects of institutional, technical and price changes on the results of dairy farms. Average results of specialized dairy...

This research demonstrates the need and the procedure for testing sector programming models It compares the model estimates of endogenous variables to carefully selected base period parameters It uses an operational, static, deterministic, and highly aggregate programming model of Philippine...
