基于鲁棒优化的灰色业务流程识别与外包策略

Identification and Outsourcing of Gray Business Process Based Robust Optimization

在运营管理过程中,决策者需要对业务流程"核心与非核心"的属性进行识别以相应地采用完全所有权或市场采购的模式。本文研究了不能被准确识别的"灰色业务流程"的模式选择,考虑了外部采购、联合开发(或部分所有权)与完全所有权的生产模式选择。根据不同模式之间的特征设计动态的外包策略与选择时机,应用鲁棒优化分析外包策略的相对遗憾。研究结果显示:在外包策略选择后,如灰色业务转变为非核心流程,转变时机越早外包策略的相对遗憾越大;如灰色业务转变为核心流程,相对遗憾随转变时机延迟而增加。在最坏情形下,策略的相对遗憾上界为1。

When firms operate, the manager must decide whether the business process is the core or no-core, and then choose an appropriate way from wholly owned subsidiary or short-term sourcing .This paper studies the out-sourcing strategy of the grey processes that can not be identified in which the manager can choose short -term sour-cing , joint venture , and wholly owned subsidiary .We develop a robust outsourcing model to analyze the relative regret of the outsourcing strategy .Our results show that after the outsourcing strategy chooses the way of grey process, the relative regret decreases as the switching timing delays if the gray process converts to no-core process;the relative regret increases as the switching timing delays if the grey process conuverts to core process . In the worst case , the relative regret is less than 1 .
