Role
of Social Networks in Supply Chain: A Literature Review
-- Sunil Bhardwaj and Sourabh
Bhattacharya
Social
networks attract the interest of supply chain researchers.
This paper reviews the contemporary studies dealing with
social networks. It delineates the studies dedicated not
only to define and classify social networks, but also to
probe into the assessment of the roles played by social
networks in supply chain arena. This paper highlights the
contemporary views on managing supply networks, and attempts
to find the gaps existing in the literature and finds the
existence of various opportunities in the area. Finally,
the paper presents the areas that require further research
works to depict and predict the role of social networks
in the operation and performance of supply chains.

A
Chance-constrained Programming Approach for Vendor Selection
-- Manoj Kumar
Vendor
selection with imprecise information is a difficult task
in the management of a supply chain. In a real-life situation
for a vendor selection problem, a lot of input information
related to the various vendors is not known with certainty.
In this paper, vendor selection is modeled as a chance-constrained
problem when the right-hand-side values of the constraints
are independent normal random variables. The model is able
to handle the net rate of return of sales revenue as a minimizing
objective with a few realistic constraints like quality
level supplied by the vendors, on-time delivery level constraint,
service level provided by the vendors, buyer's demand, and
under the uncertain right-hand-side values of constraints
related to budget amount allocated to individual vendors.
The proposed approach allows to handle the random aspects
of the problem. The effect of uncertainty variation is also
analyzed in the model. The results indicate that the quota-allocation
of different vendors may be quite different when uncertainties
are captured. At the different levels of uncertainty in
the assessment of budget amount allocated to the vendors,
the allocation of vendors' quota changes. In some cases,
few vendors loose their entire quota to the other vendors
who had buffer capacity but have superior performance under
uncertain decision parameters. The paper presents a case,
which shows the effectiveness and application of the model
to vendor selection in a supply chain.

Promethee
II for Selection of Carrier in Supply Chain
--
Srikanta Routroy and Rambabu Kodali
The
challenge for supply chain in the prevailing scenario is
to attain competitive superiority in the long run. It can
be achieved through manufacturing excellence, supply chain
coordination and logistical competency. Therefore, logistics
plays a significant role in every supply chain. The two
major transportation decisions in the supply chain are:
choice of the mode of transportation and carrier selection.
While selecting the carrier in the supply chain for any
logistics function both the qualitative and the quantitative
factors has to be taken into consideration. Hence, there
is need for a complete and structured methodology for selecting
a carrier. This paper describes an efficient methodology
`Promethee II' for carrier selection in supply chain.

System
Dynamics Approach for Strategic Supply Chain Management
-- Gujar A J, Mophare A V, Deomore D N and Khodke P M
The
long-term profitability of a supply chain is affected by
strategic decision making tools like, determination of optimal
network configuration, inventory management policies, supply
contracts, distribution strategies, supply chain integration,
outsourcing and procurement strategies, product design,
and information technology. Strategic decision-makers are
guided by comprehensive models for efficient decision-making
which increases the profitability of the entire chain. This
paper presents the guidelines for the methodology, and its
development for the strategic modeling of single and multi-echelon
supply chains.

A
Performance Measurement Model for Measuring Collaborative
Supply Chain Process
-- Juan
José Alfaro Saiz, Raúl Rodríguez Rodríguez
and Ángel Ortiz Bas
This
paper presents a methodology for measuring collaborative
supply chain business process performance. Such a methodology
aims to complement the existing frameworks and overcome
their main loopholes, which basically have to do with the
intangible aspects: coherence, equity, trust and visibility.
The paper discusses the basics of the methodology defining
the main elements of performance to be developed. Finally,
a practical application is introduced that shows the results
of applying the methodology by taking into account coherence,
equity, trust, visibility to a collaborative supply chain
business process called "Forecast Demand Visibility
for Suppliers".

Theory
of Channel Control: Revisiting an Old Debate --
R C Natarajanp
This
paper revisits the Buckin vs. El-Ansary-Robicheaux debate
of control in the marketing channel. The major weaknesses
of these two papers are: using only economic variables to
explain behavior and not clearly explaining the role of
resentment in the way in which control is accepted. This
paper briefly outlines the papers and critiques them to
form a base for an alternate model. An alternate model is
proposed using only behavioral phenomena, tolerance and
resentment as dependent variables of control. The new model
captures different stages of control based purely on behavioral
variables.

Supply
Chain Redesign Strategies Through
Identification of Uncertainty
-- Rohita
Kumar Mishra and Gokulananda Patel
The
rapidly changing business environment and the dynamic nature
of demand, call for cooperation among companies in the agri-food
supply chain. The main challenge involved is the implementation
of the supply chain management activities. The paper presents
a qualitative, as well as non-parametric research method,
for analyzing the supply chain network and for identifying
effective chain redesign strategies. The paper emphasizes
the need for the management of the sources of uncertainties
in the supply chain decision-making process.

Risk
Control in Supply Chain and Measures for Impact Mitigation
-- A Mohan
With
the increasing pace of globalization, the influencing factors
in supply chain are multiplying. The organizational success
in manufacturing is depending more on the efficiency of
each segment in the supply chain. The manufacturing operation
in a global scenario is vulnerable to any element of uncertainty
which may be caused by the prevalent environmental conditions,
either internal or external to the organization. It is of
utmost importance to raise to the occasion and identify,
evaluate, analyze and attempt to mitigate the risk caused
due to such uncertainties. This paper recounts practicing
experiences as faced by supply chain professionals in the
arena of risk management. Such experiences, sourced from
various business situations prevalent in manufacturing entrepreneurship
organizations, are presented in an illustrative manner in
order to reinforce the concepts. The aim to present such
situations is to highlight the importance to control the
impact caused in risk conditions. The paper provides a strategy
model for risk control, which has been found extremely effective
in mitigating the probability of occurrence and diminishing
the damaging impact in the supply chain. The key concept
used in the strategy model is the `Condition Monitoring'
concept, which is imported from maintenance management in
operations.
