联合经济批量模型中的损失补贴与利益分配问题研究

针对单供应商和单采购商构成的供应链系统,分采购商占主导地位和供应商占主导地位两种情形,讨论了采购商的最优订货决策与供应商的最优生产决策,以及它们合作情形下的系统最优决策,给出了采购商和供应商各自独立决策与联合决策下,它们各自的成本函数以及供应链系统的总成本函数。最后,通过比较独立决策与联合决策下采购商和供应商的成本函数,分析了联合经济批量模型中的损失补贴与利益分配问题。

基于供应链契约的生鲜农产品深加工企业决策探析

首先,通过建立数理模型对比分析了生鲜农产品深加工和初加工后的生鲜降价出售两种运作方式对供应链整体利润及相关盟员利润的影响,发现在当前供大于求的生鲜农产品市场条件下,扩大生鲜农产品深加工规模能够有效提升供应链整体及各盟员的收益水平。其次,通过建立生鲜农产品深加工企业决策模型,引入政府损失补贴机制,探究了政府损失回购力度与最优加工数量之间的关系,并给出了政府损失回购单价的合理区间。

Non-technical Losses in Brazil： Subsidies for mplementation of Smart-Grid

The amount of non-technical losses in Brazil is quite elevated, accounting for nearly 5.5% of the country＇s total generated power. Such losses are asymmetrically distributed within the various regions of the country. Meter tampering （fraud）, meter bypassing by regular consumers （theft） and irregular hookups to the network by unlawful consumers are the most predominant forms of irregularities. Part of it which is caused by non-technical losses is being passed on to the consumers through the tariffs they pay. This paper presents an overview of the current situation related to non-technical losses in Brazil involving： quantification, regional asymmetry, nature and stratification, tariff management, and strategies employed to its reduction. Advanced measurement techniques provided by smart-grids can significantly reduce them. It is suggested a potential reduction of 60%. An innovative way of using these indicators in order to identify irregularities is briefly presented in this work.
