Measuring the Bullwhip Effect in Supply Chains
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
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))
Causes of the Bullwhip Effect

Identifying important Activities within the SCOR Process Categories
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
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.
SCOR
The SCOR model consists of five major process categories: Plan, Source, Make, Deliver and Return
Starting from that best practice processes are defined up to level three. Supply Chain Operations Reference Model (SCOR, SCC 2000)

Designing the Green Supply Chain
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
Nowadays green logistics is an often heard buzz-word, but already eleven years ago Beamon published an article about the challenges with creating Green Supply Chains.
Traditional vs. Extended Supply Chain
A traditional supply chain has been mostly a one-way street. The issues analyzed were eg. the number of echelons, buyer-supplier relationships and inventory levels.
As a basis the extended supply chain has to consider at least the recycling / re-use and remanufacturing processes to be com........ Read more »

Learning from the Military how to handle Disruptions
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
Disruptions are a fact of life not only since the Supply Chain literature gained awareness of it. So some institutions in fact specialized on handling disruptions as their core competency.
The article "Responding to Disruptions in the Supply Network - from Dormant to Action" tries to transfer the knowledge and best practices present at the military and humanitarian organizations to Supply Chain Management.
Methodology
The authors (Kovács and Tatham) are using case research and a resource ........ Read more »

Perception of Supply Risk
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
One of the most published supply risk researchers is George A. Zsidisin. In his 2003 article he describes the characteristics of inbound supply that affect the perception of risk.
Supply Risk
The author defines supply risk as the potential occurrence of an incident associated with inbound supply from individual supplier failures or the supply market, in which its outcomes result in the inability of the purchasing firm to meet customer demand or cause threats to customer life and safety.
He........ Read more »

Disruption-Management Strategies for Short Life-Cycle Products
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
In his 2009 paper Brian Tomlin analyzes strategies to mitigate disruption risks in a three echelon supply chain.
Setting
Focus in his research is a single company, with its suppliers and customers. The objective is to maximize expected utility, while demand and supply are uncertain. There are two products available which can be used as substitutes. The time horizon for the decision maker is one season where the products can be sold.
Three different sourcing structures are considered.

Design of Agile Supply Chains
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
I already reviewed two other articles about agile supply chains. One on the role of distribution centers in supply chains and one on the migration from lean to agile supply chains.
But the question comes to mind if lean and agile supply chains have to be mutually exclusive or if it is possible to combine them. Christopher and Towill (2001) had a look at this question regarding the supply chain design. Continue reading "Design of Agile Supply Chains"

Supply Chain Performance and its topological features
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
Perhaps this research by Pero et al. can support small and medium sized companies with the design and redesign of its supply chain network.
The goal of the study was to analyze the connection between topological features of the supply chain and the resulting supply chain performance.
Method and Model
The authors used simulation techniques and statistical analysis to simulate a pull based supply network. The network consists of a retailer-, distributor- and manufacturer-level.
Demand and le........ Read more »

Research agenda for SCRM
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
Even though supply chain risk has been analyzed in the literature for some time (eg. the Newsvendor / Newsboy problem, with the only uncertainty being demand). Nevertheless there are still many gaps (or opportunities) within this field.
In 2007 Khan and Burnes created a research agenda for the future and most of the topics covered still can be viewed as open.... Read more »

Research issues for managing supply chain disruptions
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
What do professionals in the domain of supply chain management think about disruptions? How do they prepare for them, how do they act when a disruption occurs?

Uncertainty and Supply Chain Redesign
by Daniel Dumke in SCRM Blog - Supply Chain Risk Management
A very interesting part of Supply Chain Risk Management deals with the impact of uncertainty on the supply chain design process. Van der Vorst and Beulens (2002) address this topic, and focus on the redesign of supply chains.
They claim that sources of uncertainty can be a key driver for chain redesign and after analyzing the literature and own research (case study) they present a tool for supply chain redesign where the sources of uncertainty support the selection of the relevant strategy.... Read more »
