Prolog to the Special Section on Systems Science and Engineering

In the last decade and more, systems engineering and systems sciencehave been rapidly developed and applied in China. Scientists and ex-perts involved have achieved remarkable successes both in developingtheories of systems science and in promoting applications of systemsengineering. In theories, they not only have advanced a clear and com-     

Using the ‘Engagement’ Model of Problem Solving to Assist Students in Capstone Learning

The engagement model for problem solving was developed as a response to soft systems methodology being difficult to implement in certain circumstances. In the years since the original paper was published, the model has developed into an iterative problem solving approach for the assessment, creation and implementation of new ideas in difficult problem situations. This case study paper exemplifies the kind of work undertaken through the use of the model and provides a practical scenario for how one might apply it. The case study takes place in a higher education environment and relates to the development of a capstone course for management majors. The paper concludes with suggestions for future research.

“Underneath the iceberg” — Challenges to the process of operational research (OR)/systems from alternative practice

Conventional OR/systems practice, it is argued in this paper, is based upon assumptions which make it unsuitable for guiding interventions in nontraditional organizations. Any methodology or method rests upon a social theory,upon craft knowledge, and upon a theory of how change can and should be brought about. Conventional OR/systems is not explicit about any of these matters. Reflecting on why conventional methods often fail to work with nontraditional organizations, however, enables us to get beneath the iceberg and unearth what is being taken for granted. It is then obvious that the nature of many organizations in the social economy requires a different type of practice. Soft OR/systems is a response to the failings of the traditional approach, but goes only some way toward meeting the criticisms.     

Study on the Measurement of Industrial Structure “Sophistication,Rationalization and Ecologicalization” Based on the Dynamic Analysis of Grey Relations——A Case Study of Beijing-Tianjin-Hebei

The Beijing-Tianjin-Hebei region is one of the regions with the most dynamic economies,highest degrees of openness, strongest innovation capacities and largest populations, as well as an important engine driving China's economic development. Currently, the development of the BeijingTianjin-Hebei region faces many difficulties, including an inefficient distribution of regional functions,imbalance in industrial structure, low sophistication, and serious overburdening of resources and the environment. Promoting the overall coordinated development of the region has become an urgent challenge. In this paper, according to the conventions of industrial structure optimization, the three core indicators of regional industrial structure rationalization, sophistication and ecologicalization are constructed. With the help of the grey dynamic correlation model, the three indicators are coupled with the economic growth rate, and the industrial structure optimization index of the Beijing-Tianjin-Hebei region is comprehensively measured. The study shows that rationalization of the industrial structure in the Beijing-Tianjin-Hebei region is increasing but that this trend is not obvious; sophistication of the industrial structure is relatively high and has also been operating at a high level; however, the overall ecological level of the industrial structure in the Beijing-Tianjin-Hebei region is not high and presents the characteristics of high in the middle and low at both ends. In terms of the relationship between industrial structure and economic growth in the Beijing-Tianjin-Hebei region, ecologicalization of the industrial structure has the greatest influence on economic growth, followed by sophistication of the industrial structure, and rationalization of the industrial structure has the weakest influence.
