1 - Volume Guarantees in Global Health Procurement

, Eirini Spiliotopoulou
Recently global health buyers granted volume guarantees to pharma
manufacturers in an effort to reduce prices through competition and higher
economies of scale. However, guaranteeing volumes affect market competition
and new supplier entry in the future. Our analysis lends insights to policy makers
how to optimally structure a volume guarantee.
2 - Information Asymmetry and Competitive Implications for
Horizontal Outsourcing

We investigate the role of information asymmetry in business relationship
between competing firms. We consider a two-echelon supply chain in which a
vertically integrated (VI) firm sells a component to a component outsourcing
(CO) firm. The VI firm has its own brand which competes with the CO firm’s
product. Under this circumstance, we characterize firms’ sourcing and pricing
decisions. This work highlights the role of information asymmetry in competing
firms’ operational strategy.
3 - Impact of Channel Power and Fairness Concern on Supplier’s
Market Entry Decision
Jie Zhang, Associate Professor, Guangdong University of Finance
and Economics, 21 Luntou Road, Haizhu District, Guangzhou,

We consider a two-stage supply chain with a supplier and a retailer, and
incorporate the concepts of channel power and fairness concern to analyze the
supplier’s decision on its online direct channel. We show that a direct channel
leads to the decline of online product’s quality and its price. Furthermore, the
retailer’s order shifting strategy results in a lose-lose situation for the two firms.
We also find that the supplier’s fairness concern may make it less likely to open
an online channel.
4 - Integrated Bioenergy Supply Chain Optimization under Crop
Competition and Uncertainties

An integrated optimization program was developed to model the bioenergy
production system where dedicated energy crop is competing with incumbent
agricultural crops as feedstock. The model addresses crop adoption decisions
under competition and infrastructure deployment strategies under supply and
demand uncertainties simultaneously. A case study for the U.S. Pacific Northwest
region is conducted to obtain practical insights for the industry.
5 - Competition of Supply Chains and Their Internal Elements in a
Market with Two Classes of Customers
Masoud Narenji, Doctor, Iran University of Science and
Technology, Narmak, Tehran, 1894119493, Iran,
, Mohammad Fathia
We follow competition and coordination strategies between two chains. Each
supply chain has a manufacturer and a distributor. There are two types of
customers with different sensitivity to price and delivery time. Each member of a
chain can choose their own individual policy (dedicated or shared capacity) with
respect to importance of the customers. The evolutionary game approach was
followed to illustrate the best combination of strategy-policy, and heuristic
methods was used to solve them.

1 - Impact of NPD-SCM Alignment on Competitiveness of Indian
Automotive Industry
Bimal Nepal, Associate Professor, Texas A&M University,

This paper attempts to measure NPD-SCM Alignment and evaluate its impact on
Competitive Advantage in comparison to some established competitive priorities
such as Cost, Quality, Delivery, Flexibility, and Innovation. A large scale survey
data from Indian automobile industry has been collected and analyzed using ANP
to capture the effect of inter-dependence among variables. Findings have been
validated through three longitudinal in-depth case studies.
2 - From Actors’ Analysis to Multicriteria Decision Aiding:
A Mixed Method Approach
Valentina Ferretti, Politecnico of Torino, Corso Castelfidardo
30/A, Torino, Italy,
This paper proposes a methodological approach based on the combined use of
different tools for designing complex urban regeneration processes. The purpose
of the paper is to investigate synergies between the Social Network Analysis of
actors and stakeholders and the Analytic Network Process in order to support the
design of urban regeneration strategies. The framework has been tested on a real
case study concerning the requalification for abandoned military barracks in Turin
(Italy).
3 - Voting with Intensity of Preferences
Luis Vargas, Professor, Business Analytics and Operations, Joseph
M. Katz Graduate School of Business, University of Pittsburgh,
356 Mervis Hall, Pittsburgh, PA, 15260, United States of America,
In this paper we develop a method based on the idea of pairwise voting to rank
projects or candidates and incorporate in the ranking process how strongly the
referees/voters feel about the comparisons they make. Voting is a modified form
of ranking and all the votes are equally important. However, there are situations
similar to voting in which the votes are not just ordinal but each voter expresses
an intensity of preference for the different candidates, e.g., ranking projects for
funding.

Balance Mental Workload
Cansu Kandemir, Old Dominion University, 5115 Hampton Blvd.,

Holly A. H. Handley
This research employs a human performance modeling simulation tool with
meta-heuristic methods in order to assign personnel to tasks based on credentials,
while still maintaining a workload balance among them. An initial simulation-
optimization application on the task process of “Air Interdiction Mission
Planning” will be presented.
