Efficient Decision Makings for Dynamic Weapon-Target Assignment by Virtual Permutation and Tabu Search Heuristics

Improved Tabu search heuristics for the dynamic space allocation problem

The dynamic space allocation problem (DSAP) presented in this paper considers the task of assigning items (resources) to locations during a multi-period planning horizon such that the cost of rearranging the items is minimized. Three tabu search heuristics are presented for this problem. The first heuristic is a simple basic tabu search heuristic. The second heuristic adds diversification and i...

Efficient Heuristic Approach to the Weapon-Target Assignment Problem

The Weapon Target Assignment (WTA) problem is a fundamental defense application of operations research. The problem consists of optimally assigning a given number of weapons to a set of targets so that the post-engagement total expected survival value of the targets is minimized. Since the WTA problem is known to be NP-complete, there are no exact methods to solve it. This paper presents two in...

The Weapon-Target Assignment Problem

Comparative performance of tabu search and simulated annealing heuristics for the quadratic assignment problem

For almost two decades the question of whether tabu search (TS) or simulated annealing (SA) performs better for the quadratic assignment problem has been unresolved. To answer this question satisfactorily, we compare performance at various values of targeted solution quality, running each heuristic at its optimal number of iterations for each target. We find that for a number of varied problem ...

Effective heuristics and meta-heuristics for the quadratic assignment problem with tuned parameters and analytical comparisons

Quadratic assignment problem (QAP) is a well-known problem in the facility location and layout. It belongs to the NP-complete class. There are many heuristic and meta-heuristic methods, which are presented for QAP in the literature. In this paper, we applied 2-opt, greedy 2-opt, 3-opt, greedy 3-opt, and VNZ as heuristic methods and tabu search (TS), simulated annealing, and pa...
