Many vehicle fleet planning systems have been suggested to minimize the routing distances of vehicles or reduce the transportation cost. But the more considerations the method takes, the higher complexites are involved in a large number of practical situations. The purpose of this paper is to vehicle fleet planning system. This paper is considered multi-objective optimization. The vehicle fleet planning system developed by this study involves such complicated and restricted conditions as one depot, multiple nodes (demand points), multiple vehicle types, multiple order items, and other many restrictions for operating vehicles. The proposed algorithm is compared with the nearest neighbor heuristic(NNH) and the savings heuristic(SAH) algorithm in terms of total logistics cost and driving time. This method constructs a route with a minimum number of vehicles for a given demand. This method can be used to any companys which vehicle fleet planning system under circumstances considered in this paper.

우리는 천마의 개발 및 양산 이후에도 추가 연구개발 및 성능개량을 지속시켜 나가야 한다. 먼저 추적레이더의 S/W를 완전 국산화하고, 사격통제장치 기능을 최적화하고 방공 경보체계와의 연동능력을 보강해야 하며, 지상항법장치 등 지상장비 부수장치와 유도탄 잔종부품을 국산화하고 유도탄의 속도 및 기동력을 증대시키는 과제를 안고 있다.

The complexity of modern weapon systems using the IT(intelligence technology) demands that rapid and effective transition from force requirements to deployment and fielding. Thus this paper deals with the DT&E(developmental test & evaluation), OT&E(operational test & evaluation) and SBT(simulation based test) procedure using the case study in the test & evaluation of weapon systems. This study is aimed to produce the effective test & evaluation method of weapon systems in the change of acquisition environment.

The complexity of modern weapon systems using the intelligence technology demands that rapid and effective transition from force requirements to deployment and fielding. Thus this paper deals with the integration of development procedure, evolutionary acquisition, integrated test and evaluation, improvement of the requirements decision process, use of commercial products of high quality and low cost, specification deviation, and the effective use of dual use technology. In general, decisionmakers, and military field users shall first consider the moving technology rapidly into use. This study is aimed to improve the defence acquisition management directive for timely force integration of weapon system.

For many practical and industrial optimization problems where some or all of the system components are stochastic, the objective functions cannot be represented analytically. Therefore, modeling by computer simulation is one of the most effective means of studying such complex systems. In this paper, with discussion of simulation optimization techniques, a case study in machining process for application of simulation optimization is presented. Most of optimization techniques can be classified as single-or multiple-response techniques. The optimization of single-response category, these strategies are gradient based search methods, stochastic approximate method, response surface method, and heuristic search methods. In the multiple-response category, there are basically five distinct strategies for treating the responses and finding the optimum solution. These strategies are graphical method, direct search method, constrained optimization, unconstrained optimization, and goal programming methods. The choice of the procedure to employ in simulation optimization depends on the analyst and the problem to be solved.
