对中央部门机关政府采购开展绩效评价的几点思考

中央部门机关政府采购绩效评价,应该以党和国家关于缋效管理和政府采购的一系列重要文件为指导,针对政府采购工作全过程,以绩效目标为牵引,以绩效指标和评价标准为重点,以完善的评价组织方法为推动力,贴近实际、注重实效,按照事前、事中、事后三个阶段,客观评定中央部门机关政府采购工作投入产出比,以及工作的效益和效率情况,为政府采购工作的开展提供借鉴.     

单一时段和多时段下区域旋转备用的获取

在满足区域购买备用成本最小的目标下,基于"协调运作"的备用交易模式提出了单一时段内获取区域旋转备用容量的两种方法:①报价排队法,按照区域统一边际备用价格结算.②非线性规划法,按照机组实际报价结算,然后扩展至多时段内区域备用获取的计算,通过全局优化得到了优化后的区域备用容量,体现了区域间的备用支持,降低了获取的备用容量,优化了各地的电力资源.仿真算例分别说明了单一时段和多时段下区域备用获取的方法和计算结果.     

Did a local distribution company procure prudently during the California electricity crisis?

To manage cost risk, prudent procurement of electric power requires that some portion of a buyer's energy demand be met through long-term contracting. Under cost-of-service regulation or performance-based regulation, a local distribution company (LDC) should be allowed to fully recover all prudently incurred power procurement costs. However, the regulatory test of prudence is an ex post review with the threat of disallowance. This paper presents an economic analysis of procurement prudence involving a small LDC, Bear Valley Electric Service (BVES), which serves a resort area in Southern California. The key findings are: (a) high and volatile prices and rolling blackouts characterized the market environment faced by the owner of BVES, Southern California Water Company (SCWC), at its signing of a 5-year fixed price contract; (b) SCWC was a price-taker with no incentive to act imprudently; (c) the contract was obtained via a competitive bidding process; (d) the contract price was comparable to the benchmark price of contemporaneous contracts; (e) the fixed price contract was economic when compared to available alternatives; and (f) despite (a)–(e), a negotiated settlement with the state regulator and a large user resulted in substantial disallowance. The policy implication is that a regulator should approve a prudent procurement plan proposed by an LDC to remove the unreasonable risk of an ex post review. If the LDC strictly adheres to the plan, the resulting electricity purchases are per se prudent and should entitle the LDC to full cost recovery.

Using search theory to determine an applications selection strategy

The literature on software selection focuses mainly on identifying and ensuring the evaluation of those attributes of alternative commercial software products relevant to meeting the functional and non-functional requirements of the acquiring organisation. Once these attributes are determined, however, the firm acquiring the product must still decide on its selection strategy: which products should be evaluated, in what order, and at what point is it no longer beneficial to continue to evaluate additional products. We applied search theory to solve this problem of determining the selection strategy. This resulted in an optimal strategy but changes the way we view and manage software acquisition. In particular, the approach suggested that software acquisition may be better managed as an ongoing process instead of as a project with a distinct start and end. The approach formally incorporated the strategic importance of the application to the firm in determining the optimal strategy, a consideration that does not appear in the normal requirements-based approach to software selection.
