ROTHSCHILD and BALSIGER: LINEAR-PROGRAMMING SOLUTION 



"A practical problem which completely satisfies 

 all of the assumptions of LP is very rare indeed. 

 However, the LP model is often the most accu- 

 rate representation of the problem, which will 

 yield a reasonable recommendation for action be- 

 fore implementation is required." 



ACKNOWLEDGMENTS 



Much of the data used in this paper was un- 

 available in the literature. We obtained un- 

 published information on cannery operations 

 from several members of the salmon industry. 

 Bruce B. Bare was kind enough to advise us on 

 several aspects of the linear-programming tech- 

 nique. We also thank Donald E. Rogers for sup- 

 plying us with unpublished biological data and 

 considerable advice. We appreciate the critical 

 reviews which were given by Robert L. Burgner, 

 Gardner M. Brown, Douglas G. Chapman, and 

 Allan C. Hartt, all of the University of Wash- 

 ington, and we appreciate as well the various 

 suggestions made by anonymous referees.
