Designing effective settings for performance measures (e.g., fill rate) of a service-level agreement (SLA) is challenging. This challenge is intensified when a firm adopts the pooling inventory model to allocate inventory/capacity to multiple buyers. Each buyer has its own service-level contract outlining the required service level, the penalty structures, and the performance review period (PRP) length, which might not be the same as other buyers. This means the supplier requires an effective resource allocation policy whereby the different requirements of multiple buyers are integrated into a pooling model and capacities/inventories are allocated in the most effective way. Given a base-stock replenishment policy and finite time horizon PRP, in this study we propose two new (anticipative) allocation policies—foresight linear programming (FLP) and two-stage stochastic (TS)—and compare them with existing allocation policies. These allocation policies are developed for different penalty structures of linear, lump-sum, hybrid, and no-penalty settings. Results show that suppliers benefit from longer PRPs if linear or hybrid penalty structures are employed. We also find that when the length of PRP of buyers is not identical, TS is the recommending policy. Further, results provide a guideline for selecting the best resource allocation policy under various SLA terms, in particular, where buyers' PRP lengths are not identical.

资源池下满足异构服务需求的分配策略

为服务水平协议 (SLA) 的性能度量(例如,填充率)设计有效设置具有挑战性。当公司采用汇集库存模型将库存/产能分配给多个买家时,这一挑战会更加严重。每个买家都有自己的服务级别合同,其中概述了所需的服务级别、处罚结构和绩效评估期 (PRP) 长度,这可能与其他买家不同。这意味着供应商需要有效的资源分配政策,将多个买家的不同需求整合到一个共享模型中,并以最有效的方式分配产能/库存。给定基本库存补充政策和有限时间范围 PRP,在这项研究中,我们提出了两种新的(预期)分配策略——前瞻线性规划(FLP)和两阶段随机(TS)——并将它们与现有的分配策略进行比较。这些分配策略是针对线性、一次性、混合和无惩罚设置的不同惩罚结构制定的。结果表明,如果采用线性或混合惩罚结构,供应商将从更长的 PRP 中受益。我们还发现,当买家的 PRP 长度不相同时,TS 是推荐策略。此外,结果为在各种 SLA 条款下选择最佳资源分配策略提供了指导,特别是在买家的 PRP 长度不相同的情况下。一次性、混合和无处罚设置。结果表明,如果采用线性或混合惩罚结构,供应商将从更长的 PRP 中受益。我们还发现,当买家的 PRP 长度不相同时,TS 是推荐策略。此外,结果为在各种 SLA 条款下选择最佳资源分配策略提供了指导,特别是在买家的 PRP 长度不相同的情况下。一次性、混合和无处罚设置。结果表明,如果采用线性或混合惩罚结构,供应商将从更长的 PRP 中受益。我们还发现,当买家的 PRP 长度不相同时,TS 是推荐策略。此外,结果为在各种 SLA 条款下选择最佳资源分配策略提供了指导,特别是在买家的 PRP 长度不相同的情况下。
