In this paper we introduce the optimal solution for a simple and yet practical inventory policy with the important characteristic which eliminates the uncertainty in demand for suppliers. In this new policy which is different from the classical inventory policies, the time interval between any two consecutive orders is fixed and the quantity of each order is one. Assuming the fixed ordering cos...

We develop an algorithm to compute an optimal Q(s,S) policy for the joint replenishment problem when demands follow a compound correlated Poisson process. It is a non-trivial generalization of the work by Nielsen and Larsen (2005). We make some numerical analyses on two-item problems where we compare the optimal Q(s,S) policy to the optimal uncoordinated (s,S) policies. The results indicate tha...

the united states policy toward iran during 1985-7 is a significant issue. the us had followed a confrontationist policy toward iran after the 1979 revolution but a shift in the policy could be observed in the mid 1980's in the form of us attempts to make a rapprochement possible. this article explains this shift through the examination of the impact of this variable: solving us problems i...

We consider the stochastic joint replenishment problem in which several items must be ordered in the face of stochastic demand. Previous authors proposed multiple heuristic policies for this economically-important problem. We show that several such policies are not good approximations to an optimal policy, since as some items grow more expensive than others, the cost rate of the heuristic polic...

this paper examines the evolution of nationalism and national identity in europe and how it was transferred to and propagated in central asia by the soviets. it further examines the challenge facing central asian peoples in the post-soviet era; namely in defining a new national identity for themselves as new independent nation-states in the age of globalization. the paper attempts to demonstrat...
