承包商基于变更预期的不平衡报价策略研究

摘要

Contractors can usually find the errors such as project characteristics do not matching the description,the lack of the item, quantities deviation error and so on through the research on tender Bill of quantities or through the site survey. Then they forecast the possible state change during the contract fulfillment stage and build SEDA model to analyze the possibility of high settlement based on priced bill of quantities by setting the bidding scheme and construct intermediate state. Once a change occurs, contractors would use unbalanced bidding to achieve revenue through the pre-set intermediate state changes and be exempt from any risk. Finally,an actual case will be used to analyze the operational processes of SEDA model.%承包商通过研究招标工程量清单，发现其中如项目特征不符、缺项、工程量偏差等错误，或者通过现场踏勘，预测合同履行阶段可能出现的状态改变，构建SEDA模型，分析在已标价的工程量清单的基础上实现高价结算的可能性，设置报价方案，构建中间状态，待未来该变化发生时，通过预先设置好的中间状态借助变更提高承包商的收益，承包商可以免于任何风险从而利用不平衡报价实现创收。并通过实际案例分析了SEDA模型的操作流程。
