我们模拟的情况下，一家公司希望通过创建一个组合的经常性内包和外包合同，以平衡工作量的要求。我们使用调和分析将输入工作负载配置文件分解为使用矩形波基函数的内包和外包合同的组合，以更好地实现某些期望的恒定工作负载水平。然而，这种合同的初步选择可能导致不切实际的选择。因此，我们还开发了数学程序，使用目标规划和整数规划的原则来完善合同组合，通过对可用合同施加约束并明确考虑运营成本，更准确地反映现实环境。我们考虑了几个建模扩展，包括持有有限库存的能力，以及使用一次性合同来补充我们的经常性合同组合。
We model a situation where a firm wishes to balance workload requirements by creating a portfolio of recurrent insourcing and outsourcing contracts. We use harmonic analysis to decompose an input workload profile into a portfolio of insourcing and outsourcing contracts using rectangular‐wave basis functions to better achieve some desired constant workload level. However, this initial selection of contracts may result in impractical options. Therefore, we also develop mathematical programs using principles from goal programming and integer programming to refine the portfolio of contracts to more accurately reflect a realistic environment by placing constraints on the available contracts and explicitly considering operational costs. We consider several modeling extensions including the ability to hold limited amounts of inventory and the use of one‐shot contracts to supplement our portfolio of recurrent contracts.
