However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...

discrete facility location,   distribution center,   logistics,   inventory policy,   queueing theory,   markov processes, the distribution center location problem is a crucial question for logistics decision makers. the optimization of these decisions needs careful attention to the fixed facility costs, inventory costs, transportation costs and customer responsiveness. in this paper we study t...
