  The professional sports league has been one of the biggest business industries. And both each team manager and league manager have interested in good game schedule for the benefit. Sports League Scheduling Problem (SLSP) study had started in operation research and many researchers have been worked over the last two decades. The traveling tournament problem is recently proposed by Goerigk and Westphal which is a well-known combinatorial optimization problem aimed at developing optimal schedules for sport leagues. The TTP is considered a difficult problem in that its constraints appear to be simple but are difficult to satisfy and the objective of minimizing the total travel distance is difficult to achieve. Thus, it has been considered a challengeable combinatorial optimization problem for both theoretical and practical reasons. In this study, we present a hybrid heuristic algorithm using the Tabu search and simulated annealing procedures for solving the traveling tournament problem. Computational experiments using a hybrid approach on benchmark sets give results comparable to or better than current best known solutions.

  The primary objective of the traditional arms industry was to focus on strengthening domestic military strength. Accordingly, most of the relevant researches have focused on development and evaluation of core weapons technologies. Relying solely on domestic demands greatly limits the possibility of the arms industry’s growth. Furthermore, global financial crisis and military budget cuts are compelling the companies to seek broader markets. However, significant distinction from general export as well as both the competitiveness and high entrance barrier of the global arms trade makes such endeavor demanding. Such adversity necessitates dissimilar studies that will focus on evaluating the feasibility of exporting weapon systems and identifying promising markets. This study presents a three-step analytical procedure that combines both quantitative and qualitative approaches to address this issue, selection of buying power indices and evaluation of competing weapons systems, two-phase screening for selecting promising countries using both quantitative and qualitative analyses and final selection of target countries by utilizing the Bruce Merrifield-Ohe (BMO) Method. The proposed research is evaluated by applying the proposed procedure to two actual weapon system export cases in Republic of Korea with opposite results a success and a failure.
