Decision making time assessment in multi-level periodic production management

This paper presents a comprehensive mathematical model in order to evaluate the impact of periods offset on decision making time performed in complex multi level decisional systems. The proposed approach consists in decomposing the global reaction process into several sub-processes and activities characterized by their nature and duration. Considering that decisions are periodically made, it is proved that global decision making time is related to all waiting times induced by periodic management. Reducing the reaction time consists in minimizing these waiting times. The principles of reaction processing time reduction are then illustrated by an academic example
