A case study in Taiwan reveals that newcomers to system dynamics tend to use qualitative models without performing simulation. To develop quantitative simulation skills, this study identifies simulation barriers in the early stages and proposes an evolutionary approach to overcome such barriers. The simulation learning process is separated into two stages: the initial similation skill's development and the system dynamics expertise. A special purpose simulation software is then designed as well as a course established to test and evaluate the approach to the initial stage. The results of the study indicate that the approach with the software can help facilitate learners in developing initial simulation skills with a model scale of about two levels and forty equations. Thus, different stages require various approaches to the learning of quantitative system dynamics skills.

A long period of economic and industrial development has allowed developing countries to evolve into newly industrialised countries (NICs). Simultaneously, the development of their major weapon systems has evolved from foreign weapons acquisition to independent development due to establishing research and development (R&D) capabilities. However, competitive pressures in the international arms market has finally led these countries to return to foreign acquisition, consequently rapidly eroding their R&D capability. Balancing foreign acquisition and independent development is a long-term strategic problem for NICs. This study applies the system dynamics methodology to construct a weapon systems development model for Taiwan. This model is used to analyse the impact of acquisition policy. The results here indicate three major possible growth curves for weapon systems R&D capability based on alternative weapon systems acquisition policies.
