Description:
The purpose of this paper is to describe the implementation and testing of the tabu cycle method and two variants of the conditional probability method. These methods were originally described in Glover and Laguna [Tabu search. Boston: Kluwer Academic Publishers; 1997] but have been largely ignored in the tabu search literature. For the purpose of testing, we employ a single-attribute implementation of a short-term memory procedure for the solution of a single machine scheduling problem. Computational experiments that employ instances with up to 200 jobs reveal the usefulness of the tabu cycle and the conditional probability methods as viable alternatives for managing the short-term memory in a tabu search implementation. ...

Product Description
This is a AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH SCHOOL OF ENGINEERING AND MANAGEMENT report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A889093. The abstract provided by the Pentagon follows: The Combined Mating and Ranging Planning System (CMARPS) is the system used by AMC to schedule air refueling for deployments from the continental U.S. to other parts of the world. The tool developed by Capehart (2000) got results similar to CMARPS in less time. Capehart's tool allows AMC to input several receiver groups consisting of various aircraft types and numbers. Each receiver group contains a point of origin and destination, with the option of providing one waypoint along the path, a ready to load date (RLD) and required delivery date (RDD). The user is also able to specify the locations of military tanker aircraft. The main goal of this tool is to assign the tankers to the different refueling points of the receiver groups so that all receiver groups arrive before their RDD. Secondary goals include the reuse of tankers and limiting the total flight distance for all tanker aircraft. The main purpose of this research is to introduce a dynamic feature of tabu search, reactive tabu search, into the tool. This method changes tabu tenure when necessary in the hope of finding better solutions by diversifying the search to the unexplored areas of the solution space. ... Read more

It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A526163. The abstract provided by the Pentagon follows: This paper presents a methodology for solving military aircraft load- scheduling problems modeled as a multidimensional multiple knapsack problem, Because of the computational time associated with applying conventional algorithms to this type of problem, we employ tabu search to determine how much cargo a heterogeneous group of aircraft can carry. This study extends the previous work of Chocolaad in two areas. First, we modify Chocolaad's algorithms to solve the multiple (rather than the single) knapsack problem under the constraints he defmed for the Airlift Loading Problem. Second, we drop his assumption of a homogeneous group of aircraft. We validate our model by confirming its solutions with cargo loadmasters, and comparing the performance of our algorithm with the benchmark ALM. ... Read more

The abstract provided by the Pentagon follows: In this research, we provide a new meta-heuristic, a jump search Itabu search hybrid, for addressing the vehicle routing problem with real-lifeconstraints. A tour construction heuristic creates candidate solutions or jumppoints for the problem. A tabu search algorithm uses these jump points asstarting points for a guided local search. We provide statistical analysis onthe performance of our algorithm and compare it to other published algorithms.Our algorithm provides solutions within 10% of the best known solutions tobenchmark problems and does so in a fraction of the time required by competingalgorithms. The timeliness of the solution is vitally import to the unmannedaerial vehicle (UAV) routing problem. UAVs provide the lion's share ofreconnaissance support for the US military. This reconnaissance mission requires the UAVs to visit hundreds of target areas in a rapidly changing combatenvironment. Air vehicle operators (AVOs) must prepare a viable mission plan for the UAVs while contending with such real-life constraints as time windows,target priorities, multiple depots, heterogeneous vehicle fleet, and pop-upthreats. Our algorithm provides the AVOs with the tools to perform their mission quickly and efficiently. ... Read more
