Özet:

 





In this study, Turkish red pine and Anatolian black
pine seedling production at different ages were planned with linear programming
method and maximizing the seedling revenues was aimed. In this respect,
according to the assumptions used in the model, fields in various sizes such as
10000 m2 area for one year old, 20000 m2 for two years
old, 30000 m2 for three years old and 40000 m2 for four
and five years old seedling were separated in the nursery. On the other hand,
balanced seedling production in consecutive years and consideration of demand
increase or decrease on the seedling production at any ages were main goals.
For this, developed model was solved in three different formats deal with rapid
demand increase (RDI), slow demand increase (SDI) and demand decrease (DD)
scenarios. Obtained results showed that if there is a rapid increase in demand,
largest present value was 385310 andtotalproducedseedlingnumberwas905262.Realizationofslowdemandincreasehasledtoreductionof6658andtotalproducedseedlingnumberwas905262.Realizationofslowdemandincreasehasledtoreductionof6658 and total produced seedling number was
905262. Realization of slow demand increase has led to reduction of 6658 
(1.73%) in present value, and 17461 piece in produced seedling number. However,
reduction of demand decrease caused to occur present value 24989 $ (1.93%) and
produced seedling number 61479 piece (6.79%) less.
