What is an interventionist order picking strategy? What is the key idea behind “interventionist “strategy? Identify the two approaches that researchers have taken to maximize service level provided by order picking systems. State clearly the distinction between in a stochastic setting/ a deterministic setting. And give some examples. Following the completion of the literature overview section, we can draw conclusion about the current strategies in order picking that can be summarized in four key points: Identify any two key points.
