Assigning products to and retrieving them from proper storage locations are crucial in minimizing the operating cost of a unit-load warehouse. The problem becomes intractable when the warehouse faces variable supply and uncertain demand in a multi-period setting. We assume a factor-based demand model in which demand for each product in each period is affinely dependent on some uncertain factors. The distributions of these factors are only partially characterized. We introduce a robust optimization model that minimizes the worst-case expected total travel in the warehouse with distributional ambiguity of demand. Under a linear decision rule, we obtain a storage and …

Becoming Aware Of The Unknown: Decision Making During The Implementation Of A Strategic Initiative, Ronald Klingebiel, Arnoud De Meyer

This qualitative study analyzes the decision-making process involved in adapting preconceived courses of action during the implementation of a strategic initiative. We observe that the type of decision-making process hinges on the nature of managers’ emerging awareness of future events. When managers become aware of new uncertainty, the process involves selectiveness, deliberateness, and diligence. By contrast, when managers become aware of new certainty, the process conforms to the problem-solving adhocracy and decision-making messiness emphasized in prior literature. We summarize our findings in a framework, proposing that decision-level differences in awareness and uncertainty can explain the observed variation in strategic decision-making …
