BCL (base class library) project cost calculation description language and compiling and executing method thereof

Abstract

A BCL (base class library) project cost calculation description language and a compiling and executing method thereof comprise three aspects of content: 1, the BCL project cost calculation description language which is implemented by designing an algebraic expression and extended operation expression structure, namely an EL (expected loss) expression, for descripting specific computational algorithm rules, as well as analyzing project cost computation requirements and determining other computational algorithm units except the EL expression; 2, a device for compiling and executing a BCL language, which comprises a BCL compiler device, a BCL script analysis device and a BCL executor device; and 3, one compiling and executing method of the BCL project cost calculation description language. According to the invention, a cost computation process can be restored really, and a user visually and conveniently browses content such as a generation process of cost, data sources and the like; and besides, the BCL script analysis device provides an interconversion function between a BCL object cluster and a BCL script file, so that multiple times of execution by one-time generation are realized, and the execution efficiency is effectively improved.
