We consider a model in which there are m products and for each i=1,...,m, there are ni observations of the service times associated with the th i product. Assuming the service times associated with the th i product follow an exponential distribution with parameter i θ , and i θ 's are independent random variables with a common gamma distribution, with unknown parameters α and β , we provide two...

In this paper, a new approach for due date assignment in a multi-stage job shop is proposed and evaluated. The proposed approach is based on a genetic programming technique which is known as gene expression programming (GEP). GEP is a relatively new member of the genetic programming family. The primary objective of this research is to compare the performance of the proposed due date assignment ...

it is shown in [1] that the optimal downlink radio resource allocation for non-realtime traffic in cellular cdma/tdma networks can be mapped to a multi-dimensional multiple-choice knapsack problem (mmkp) which is np-hard. in this correspondence we propose a heuristic algorithm with polynomial time complexity for this problem. numerical results indicate significant computational performance impr...
