Objectives define the boundaries of complex engineering system. It is a hard work to determine 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 to qualitativeness to quantitativeness (a recurrent process), expert experience and theoretical science, rationality and sensibility, synthetic analysis and meta-synthetic, 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.

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.
