This study concerns logistics support analysis record(LASR) which provides guaranteed support, and is needed in various weapon systems development and acquisition to develop the optimal factor for integrated logistics support(ILS) by reflecting the results of logistics support analysis(LSA). We observe and analyze the logistics management information(LMI) system used in the United States under the integrated data environment(IDE), and analyze the differences between logistics management information system and the LOADERS(logistic support analysis data entry and retrieval system) which is currently used in Korea. Based on the analyzed results, a improvement model that corresponds to reality and can be applied is presented.

This study reconstructed the military logistics improvement project currently being implemented by ROK military as a defense logistics strategy. In addition the factors affecting the performance of the defense logistics strategy are analyzed using PLS. The significance of this study is as follows. First, the defense logistics improvement project was structured as a defense logistics strategy according to function. Second, PLS is used for performance factor analysis. Most of the existing defense researches utilized the ML structural equation. However, this study used the PLS structural equation in view of the fact that each detail project is the formation of defense logistics strategy. Third, we identified projects that have a substantial impact on defense logistics performance and those that do not. We found that inventory, process, and information strategy influenced logistics performance among defense logistics strategies. On the other hand, it was confirmed that the facility/equipment strategy had no significant effect on defense logistics performance.

In the military logistics, the Outsourcing such as 3PL (3rd Party Logistics) and 4PL has emerged recently as an important agenda. However, when 3PL applied prematurely, side effects will occur such as the loss of combat power in wartime, the security vulnerabilities and the high cost by a small amount of military order. Recently, the developed countries such as the United States and the Britain want to compensate for these side effects. Therefore, They are developing the private-public competitive sourcing concept for the complementary partnership and the foster competition with the private sector. To apply this concept to the Korean Military, they need to be reorganized and promote the efficiency in the military logistics. Especially, the transportation sector. Therefore, this study, which is focused on the transportation sector, offers two kinds of measures to improve such as the Dual Pallet Standard (T11, T12) and the PLS(Palletized Loading System) truck system. Finally, these improvements will be analyzed by the simulation in this paper.

It is very important for weapon systems to manage the logistic support for the better combat readiness. Therefore, in this paper we review the issues of logistic support and suggest alternatives to effectively manage the logistic support for weapon systems by using performance based logistics, especially during operations and support phase.

The SCOR(supply chain operations reference) model which is a management tool, has been developed to describe the business activities associated with all phases of satisfying a customer's demand. The model is able to successfully describe and provide a basis for supply chain improvement. In this paper, we review the SCOR model, the present status of the Korean defense logistics system, and suggest an application of the model for the integrated defense logistics system.

In war time, minimizing the logistics response time for supporting military operations is strongly needed. In this paper, i propose the mathematical formulation for minimizing the maximal acquisition completion time in wartime or during a state of emergency. The main structure of this formulation is based on the traveling purchaser problem (TPP), which is a generalized form of the well-known traveling salesman problem (TSP). In the case of the general TPP, an objective function is to minimize the sum of the traveling cost and the purchase cost. However, in this study, the objective function is to minimize the traveling cost only. That's why it's more important to minimize the traveling cost (time or distance) than the purchase cost in wartime or in a state of emergency. I generate a specific instance and find out the optimal solution of this instance by using ILOG OPL STUDIO (CPLEX version 11.1).

Modernization projects are actively underway to replace conventional logistics equipment for the development of the 21st century logistics management system. The modernized logistics system is expected to expand to each troops on future. In this paper, we deal with simulation of automated logistics center to analyse the current system. Especially, the alternative to the same scale is designed based on needs of military distinctiveness. As a result, it can be effectively compared the current system. The result obtained in this design process is comprehensively analyzed by the AHP(Analytic Hierarchy Process). The proposed method in this study is allowed to cost-effectively evaluate current and future automated logistics center. And, that is expected to contribute to modernization projects of the military logistics system.

We find out optimal solution of this problem by using ILOG OPL STUDIO(CPLEX v.11.1) and do the sensitive analysis about computing time according to number of operated vehicles.

MRO is important concept in military logistics. It is required to reforming military budget and manpower because of decreasing troops and other factors. For this reason, military logistics needs to change and improvement. MRO is necessary concept in this situation. In that case, How improve Naval Weapons Systems MRO for this changing time? For example, ROK air force applies Aerospace MRO industries in their Weapons Systems. But, ROK navy's MRO concept is uncertain and current MRO is divided just three step, Organizational Maintenance, Field Maintenance, Depot Maintenance. So it is time to develop systematic MRO concept for improving Naval Weapons Systems and Logistics. In this research, This0 study is about expanded application of PBL and the need to make relationship between Private enterprise and Military.

Victory and defeat of the war depends on follow-on logistics support. The spending time of follow-on logistics support at combat area is greatly influenced by the degree of combat intensity. The main purpose of this study is to compose a optimal supply route for operational sustainability of combat unit at combat area using transport vehicles. This study suggests a composition of optimal supply route for follow-on logistics support which considers the degree of combat intensity. A mathematical programming model and a genetic algorithm suggest to minimize the total spending time of follow-on logistics support. The suggested mathematical programming model is verified by using CPLEX 11.1. This study computes supply route, total spending time, total travel distance, and the number of transport vehicle.
