| Decision support systems are generally geared to short-term tactical decision making. As an alternative, this paper develops a mathematical programming model to evaluate long-term strategic alternatives in the context of farm-level agricultural production where a broiler farm considers long-term implications of diversification into commercial aquaculture. The model considers a ten-year strategic planning horizon, incorporates financial risk and return considerations, and accommodates capacity variations. Results indicate that a diversification strategy significantly increases farm profitability over a strategic planning horizon while simultaneously maintaining financial risk below a predetermined tolerance level and return on investment above a... |

We describe how we transformed a two-course sequence in research methods into a problem-based-learning format. Student-reported benefits of the PBL approach include the need for higher-order thinking, improved group interaction skills, relevance of course material to real world situations, higher... |
