Fisheries management is complicated in nearly all cases by various types of uncertainty. Numerous economics and fisheries science publications prescribe adjustments to harvest strategies and regulations in the face of uncertainty. The conclusions and recommendations from this body of work are...

We consider a two-station tandem queueing system where customers arrive according to a Poisson process and must receive service at both stations before leaving the system. Neither queue is equipped with dedicated servers. Instead, we consider three scenarios for the fluctuations of workforce...

We analyze a finite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are random variables that are independent of each other and their distributions depend on the product price. Pricing and...

Optimal control theory has been extensively used to determine the optimal harvesting policy for renewable resources such as fish stocks. In such optimisations, it is common to maximise the discounted utility of harvesting over time, employing a constant time discount rate. However, evidence from...

An optimising model is developed to determine the .sequence of total allowable catches of western mackerel which would result in the maximum present value of the stream of annual rents. It is found that the optimal steady state fishing mortality would be one half to one third of recent levels....

A multiobjective bioeconomic policy model was developed for the United States Pacific whiting fishery. Pareto-optimal solutions for three policy objectives—rents, production, and female spawning biomass—were developed and analyzed using "hybrid" generating technique. Three policy instruments...

This study involves an update of our earlier Timber Supply Model, which was fully developed in our book, The Adequacy Of Global Timber Supply by Sedjo and Lyon (1990), published by Resources for the Future. The new version, called Timber Supply Model 1996 (TSM96), uses an economic market...
