This paper summarized the three things included in concept of core-competitiveness: integrative ability, core technology and core product. It reviewed main factors for increasing core-competitiveness, which include core technology, resource integration, information exchange and strategic alliance establishment. It studied the wildly used indicators in core-competitiveness assessment model, such as financial status, business management, technology innovation and enterprise culture. Through case study in China Railway Jiujiang Bridge Engineering Co.Ld, the writer got the conclusion that Chinese Railway and Bridge enterprises should focus on industrial integration and innovation to enhance core-competitiveness. 展开更多

Objectives define the boundaries of complex engineering system.It is a hard work to identify the specific objectives of a complex engineering system.The objectives system development needs a complicated process,from nix to prototype,and to final definition.The total process will cover the following course:from chaos to well-ordered;from qualitativeness to combination of quantitativeness and qualitativenss,then from qualitativeness to quantitativeness(a recurrent process),expert experience and theoretical science,rationality and sensibility,synthesis analysis and meta-synthesis,routinization and non-routinization.Such process is explicit in phase development yet overlapped;mutually confined yet mutually independent;permeated conflicts yet pregnant in harmony.This article explores the complexity of Sutong Bridge's objectives development and the process of meta-synthesis in the Sutong Bridge engineering. 展开更多
