Revisiting rescheduling: MRP nervousness and the bullwhip effect

Investigation the Combination of the Bullwhip Effect Weakening and the Anti-Bullwhip Effect Strengthen

Returns and the bullwhip effect

An almost universal assumption in the bullwhip effect modeling literature is that excess goods may be returned without restriction. We seek to determine if returns impact the level of bullwhip effect observed in a multi-stage supply chain. We build a hybrid agent/ discrete-event simulation model of a supply chain and execute it under various conditions of demand variance, lead-time variance, in...

Managing the Bullwhip Effect

The bullwhip effect is the inherent increase in demand fluctuation up the supply chain (i.e., away from customer). Managing the bullwhip effect is minimizing the fluctuation and variation of the demand (i.e., orders from one stage of a supply chain to the next stage of the supply chain) throughout the supply chain. This paper will offer a literature review of this topic, note the key contributi...

Modeling and Measuring the Bullwhip Effect

The bullwhip effect is a phenomenon commonly observed in industry. It describes how the distortion of demand information in a supply chain amplifies demand variance as it moves from consumption point up the supply chain to layers of suppliers. The bullwhip effect has been a subject of intensive research activities. Researchers have tried to address questions such as: What causes the bullwhip ef...

Nervousness

Nervousness is one of those quasi-technical terms which are to be reprobated for their vagueness, but which cannot be got rid of. We refuse to admit them into strictly scientific nomenclature, but we are not able to ignore their existence. Nervousness is one of the most obnoxious as well as one of the most commonly used of these terms. It is most obnoxious, because in its pathological significa...
