Case study’s can give valuable insights for the researcher, but there are many preconceptions about this research methodology, like being too subjective or having a too small sample size to deduce any relevant information.This is also how Flyvbjerg (2006) starts his paper on the “Five Misunderstandings About Case-Study Research“.
He therefore claims the following misunderstandings:
Within a supply chain many supplier-buyer relationships exist. Even though supply chain management aims to take a high level view, these dyadic relationships form the basis of the supply chain and therefore should be the focus of a supply chain analysis.
The negotiation of the terms of these relationships defines the structure of the supply chain and can affect the power and profit distribution within the supply chain itself.
So, this week we’ll have a closer look at negotiations in the supply chain using a 2008 paper by Frederik Zachariassen.
The bullwhip effect in supply chains has been around for some time now. The term “bullwhip effect” originated at Procter & Gamble, and is defined as: demand amplification across echelons within a supply chain. This describes the effect that end customer demand may be very static (as for “Pampers” by Procter & Gamble), but the demand experienced by the manufacturer or supplier shows amplified demand variations. (Fransoo and Wouters (2000))
This review is about a preprint article which already has been accepted for publication by the “European Journal of Operational Research”. But since there is only a limited space for articles in each issue of the journal, final publication of the article is delayed.
Some weeks ago I wrote about Fisher’s suggestions on how to select the right supply chain for your product. But how to continue from there? How do different products affect the further planning steps needed?
The quantification of supply chain planning is the next step in the field of supply chain optimization. After operational and logistical aspects have been modeled and optimized, margins for further improvement remain slim.
Based on this premise the paper I review today suggests and tests several alternative multilevel planning approaches to gain further supply chain improvements by optimizing the mid-term supply chain design.
The Supply Chain Operations Reference (SCOR) model has been developed by the Supply Chain Council to provide a best-practice framework for supply chain management practices and processes with the goal to increase performance.
The SCOR model consists of five major process categories: Plan, Source, Make, Deliver and Return
