The purposes of this study are to identify chracteristics and behavioral patterns of acquisition of military weapon system in Korea and then to develop an project selection models for military weapon system.
Based on the review of the relevant literature and the analysis of existing system, a new four-step model of project selection is suggested to improve the shortcomings of the existing scoring models for military weapon system.
First, checklist should be used as a first step of project selection to screen a large number of alternatives. Second, based on key requirement, the hierarchical structure for military weapon system should be prepared as a platform to draw opinions of military experts systematically. third, weights for each level of evaluation criteria should be calculated using Analytic Hierachy Process(AHP) and Delphi technique. Finally, scores for each criteria should be given based on utility functions derived from the pairwise comparison technique.
In order to validate the applicability of the proposed scoring model of project selection, main battle tank project of Korean Army selected and relevant data are collected.
The results of application show that the proposed model for selection and acquisition of military weapon system can be used practically. in addition, some analyses are made and management guidelines are obtained as follows:
First, this study analyses and summarizes existing acquisition and management practices for military weapon system and suggests some directions to modify and improve existing project selection(scoring) models. in addition, some management implications in using a new four-step model are presented.
Second, the proposed scoring model shows new approaches to evaluate "weights" and "scores" for each criteria. For weights, AHP and Delphi method are applied based on the expert's jugements. utility function derived from pairwise comparison is used to endow "scores" for each criteria. these new approaches are compared with existing ones and show better performance. it means that the proposed model can be implemented in real situation to improve the existing system.
Third, through the application of new model into the main battle tank project, some considerations for better use of the model are discussed. they include relevant formation of hierachical structures, appropriate grouping of criteria, selection of experts and so forth.
But the result does not mean that the proposed model is the "best" project selection model. it simply implies that the proposed "scoring" model is better than "existing scoring" model.
Therefore, more careful comparisons with other project selection models such as AHP should be made in the further study.
