从供应链的角度来看,定制的基础升政策 (TBS) 通常优于双源库存系统的双指数政策 (DIP),特别是在一般的交付时间方面. 对于制造商来说,TBS提供了一个简单,有益的替代方案.
科学领域:
- 运营研究 运营研究
- 供应链管理 供应链管理
- 库存理论 库存理论
背景情况:
- 双重采购库存系统涉及采购者使用常规 (低成本,离岸) 和快速 (响应,近岸) 供应商.
- 现有的研究主要从买方的角度评估这些系统,忽视了供应链的整体利.
- 该研究涉及具有一般 (非连续) 交付时间的系统,其中最佳策略是复杂的或未知的.
研究的目的:
- 从整体供应链的角度评估双重采购库存政策,同时考虑买家和供应商.
- 为了在一般的交付时间条件下比较双指数政策 (DIP) 和量身定制的基础升政策 (TBS) 的表现.
- 确定在双层环境中,哪一项政策对供应链利能力更有利.
主要方法:
- 双指数政策 (DIP) 和量身定制的基础升政策 (TBS) 的数值比较.
- 在各种条件下进行评估,重点是两级双采购库存系统.
- 分析基于51家制造业企业的数据.
主要成果:
- 从供应链的角度来看,量身定制的基础升政策 (TBS) 通常优于双指数政策 (DIP),即使有有限的交付时间差异.
- TBS在几个周期的交付时间差异上证明了有效性,挑战了之前的假设.
- 该研究证实,TBS是双重采购供应链的有利和结构简单的政策替代方案.
结论:
- 量身定制的基础升政策 (TBS) 是优化双源库存系统的强有力的竞争者,在考虑整个供应链时,它比双指数政策 (DIP) 有优势.
- 这些发现表明,制造企业可以很容易地采用TBS来提高供应链的性能.
- 这项研究强调了供应链全方位视角在评估库存政策方面的重要性,特别是对于具有复杂交付时间结构的系统.

Parameters Affecting Nonlinear Elimination: Zero-Order Input, First-Order Absorption and Two-Compartment Model
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...

One important characteristic of noncompartmental analyses is that drug exposure increases proportionally with increasing doses. This...
Nonlinear Pharmacokinetics: Causes of Nonlinearity
Nonlinear drug absorption can occur when the process is rate-limited by solubility, carrier-mediated transport systems, or saturation of the presystemic gut wall or hepatic metabolism. For instance, high doses of riboflavin...
