2. 2 Framework - what is it Classification and structuring of a field
indicating relations between the various elements
Difference with
taxonomy - based on observed characteristics
typology - classification based on outside aspects
these do not give relations
Validation?
- internal consistency, completeness, parsimony
- quite subjective - should stick and be appealing
- data sources - case study review, own insight, other framework proposals
3. 3 Reverse Logistics - introduction What is it - definitions
�� the movement of goods from a consumer towards a producer in a channel of distribution.� (Pohlen & Farris)
�The process of planning, implementing and controlling flows of raw materials, in process inventory, and finished goods, from the point of use to a point recovery or point of proper disposal�
(Revlog)
issue:
is the word �use� correct? e.g. stock adjustments
�point of consumption to the point of origin� (Rogers &TL)
alternative: �from a manufacturing, distribution or use point to a point of...�
4. 4 Reverse Logistics - introduction What is it - history
Terms like Reverse Channels or Reverse Flow already appear in the scientific literature of the seventies, but consistently related with recycling (Guiltinan and Nwokoye, 1974; Ginter and Starling, 1978).

5. 5 Reverse Logistics and other fields - closed-loop supply chainsstresses integration forward and reverse chains,
- environmental conscious manufacturingconcerns manufacturing
- green logisticsstresses environmental aspects of logistics, esp. forward log.
- waste logistics managementprimarily oriented at waste which is not recovered
- sustainable development
overall term indicating economic activities while taking a long-term holistic view (economics and ethics)
mainly macro studies: reverse logistics is very much the implementation at the operation management / logistics level
6. 6 A structuring of reverse logistics: why, what and how why is reverse logistics done- drivers
- return reasons
what is returned?- products and characteristics
how is reverse logistics done - actors
- processes
7. 7 Reverse logistics: why Three main drivers
economics (direct and indirect, marketing, competition, etc)
ethics (environmental aspects, business principles, etc)
legislation
In reality reasons overlap - e.g. pending legislation, etc
Q: can we really take these 3?
