论文摘要
产品多样性是客户满意的重要因素之一，而从公司的角度来看，产品多样性所需的额外工程成本不应超过其市场份额增加所获得的利润。因此，针对公司的关键决策任务之一是选择最佳产品组合，即产品组合管理（PPM）。关于PPM问题的传统研究对其他竞争对手的行为的关注相对较少。在本文中，我们在竞争环境中研究了PPM问题，在竞争环境中，每个公司的目标是最大化其预期的共享盈余。我们使用$ n $播放器游戏对竞争对手进行建模，即最佳产品组合是从其NASH平衡中驱动的。公用事业功能取决于共享盈余的期望值。我们分析公司的战略行为以确定其最佳产品组合。
Product diversity is one of the prominent factors for customers' satisfaction, while from the firms' perspective, the additional engineering costs required for product diversity should not exceed the acquired profits from the increase in their market share. Thus, one of the critical decision-making tasks for companies is the selection of an optimal mix of products, namely product portfolio management (PPM). Traditional studies on PPM problem have paid relatively less attention to the actions of other competitors. In this paper, we study PPM problem in a competitive environment where each firm's objective is to maximize its expected shared surplus. We model the competition with an $n$-player game that optimal product portfolios are driven from its Nash equilibrium. Utility functions are determined by the expected value of the shared surplus. We analyze the strategic behavior of firms to determine their optimal product portfolios.
