基于生产前沿面的DBB与DB交易方式下工程项目生产效率比较研究

Comparison of Project Production efficiency between DBB and DB delivery system on Production Frontier

摘要:

工程项目交易方式是影响项目成功的关键因素之一。本文从工程项目生产效率的视角，应用生产前沿面与数据包络分析方法，建立了工程项目交易方式生产效率指标体系，构造了工程项目交易方式生产前沿面，对“设计/招标/建造”（简称DBB）与“设计/建造”（简称DB）进行比较。通过比较生产效率相对最优的DBB与DB项目，得出DBB方式在成本方面更有优势，而DB方式在工期方面更有优势，并分析了得出这种结果的内在机理，从而为业主科学地进行工程项目交易方式选择决策提供了支持。

Abstract:

Project Delivery System (PDS) is one of the crucial success factors for construction project. From the perspective of Project Production efficiency, this paper constructed a project production efficiency index system and built the corresponding project production frontier of PDSs for comparing Design-Bid-Build(DBB) and Design-Build(DB) delivery system by applying Production Frontier and Data Envelopment Analysis method. Basing on the comparison of DBB and DB’s efficiency, this paper draw a conclusion that DBB delivery method has advantage in duration, while DB has advantage in cost. On such results, the inner mechanism was further explored, thus to provide a scientific decision- making support for owner’s PDS selection practice.
