Software systems evolve and change with time due to change in business needs with the result that at some stage, the original design and architecture descriptions may not give exact representation of the actual software system. Accurate understanding of software architecture is very important for software maintenance because it helps in estimating scope of change, re-usability, cost, and risk i...

The paper introduces an approach for crosstalk-free bitpermute-complement (BPC) permutations routing in hybrid optical variable-stage shuffle-exchange networks (SENs) of size where N=2, and the number of stages can vary in . The number of stages should be asserted as required by a given BPC permutation for its admissibility. The crosstalk is caused by interacting of two optical signals within t...

The traveling salesman problem (TSP) is one of the most important combinational optimization problems that have nowadays received much attention because of its practical applications in industrial and service problems. In this paper, a hybrid two-phase meta-heuristic algorithm called MACSGA used for solving the TSP is presented. At the first stage, the TSP is solved by the modified ant colony s...

A heuristic for decomposing traffic matrices in TDMA satellite communication. With the time-division multiple access (TDMA) technique in satellite communication the problem arises to decompose a given n x n tramc matrix into a weighted sum of a small number of permutation matrices such that the sum of the weights becomes minimal. There are polynomial algorithms when the number of permutation ma...

Abstract— This Paper proposes a novel batch mode scheduling heuristic for scheduling of independent jobs on heterogeneous Grid resources. Proposed heuristic works in two stages, in the first stage Min-Min heuristic is being followed for the assignment of jobs to the resources & in the second stage jobs are being transferred from heavily loaded resource to the lightly loaded resource to achieve ...

The efficiency of designing a large-scale structure with many variables can often be increased by decomposing the design problem into less complex sub-problems. This article presents heuristic procedures of determining an appropriate design sequence to solve decomposed structural optimization problems using a sequential design (singlepass) strategy. One heuristic procedure exploits the monotoni...

As an essential part of decision-making in recent business processes, this study has called attention on entire network associated with supply-chain management. To optimize such large-scale and complex systems, we proposed a hybrid method compose of meta-heuristic method and mathematical programming after decomposing the problem into two sub-problems in a hierarchical manner. Then we provide a ...
