In-Depth Information
Environmentally-friendly (sustainable) packaging's materials help reduce global
warming, carbon footprint and greenhouse gases. In addition, they divert tons of plas-
tic and other non-degradable materials from our landfills. Sustainable packaging is a
relatively new addition to the environmental considerations for packaging, so selec-
tion of green packaging supplier has a pivotal role in green supply chain of food
production.
In this chapter a methodology for green supplier selection (GSS) in food indus-
try is developed. Systematic integration of technique for order of preference by
similarity to ideal solution (TOPSIS), analytic hierarchy process (AHP) and grey
relational analysis (GRA) techniques is implemented. A case study on determi-
nation of criteria and ranking of potential packaging material suppliers in food
company is illustrated.
2 Literature Review
Typically there are two kinds of supplier selection approaches: single sourcing
and multiple sourcing (Ghodsypour and Obrien
1998
). In the first kind of supplier
selection, one supplier can satisfy all the buyer's requirements but in multiple
sourcing company need to select a collection of selected suppliers and their allo-
cations. Purchase manager makes a strategic plan for the number of suppliers
according to the specifications of the company, product and market.
2.1 Decision Making Techniques in Supplier Selection
There are several different decision making techniques used mostly for supplier
selection divided in three main group of multi-criteria decision making (MCDM),
mathematical programming and artificial intelligence techniques as shown in Fig.
1
(Chai et al.
2013
). Ranking results of MCDM and mathematical programming in
multiple source approaches, are developed to determinate allocation of high ranked
suppliers (Ghodsypour and Obrien
1998
). Chai et al. (
2013
) indicated that the most
frequently used technique in supplier selection is AHP followed by linear program-
ming and TOPSIS. Recently combination between techniques is usually adopted
to deal with the problem of supplier selection. Ho et al. (
2010
) and Govindan
et al. (
2013
) divided decision making techniques used for supplier selection into
individual approaches and integrated approaches critically. The use of appropri-
ate techniques can bring effectiveness and efficiency to the selection process
(Boer et al.
1998
). Techniques are differing from several aspects of: supporting
decision maker group, type of criteria, number of potential suppliers and crite-
ria, criteria independence, uncertainty, agility in decision process and complexity
in computations. To select techniques one must take into account the alignment of
the particularities of the problem at hand with the characteristics of the techniques
(Junior et al.
2014
).
