This research presents a single-vendor, single-buyer integrated inventory model
under stochastic lead-time environment and late delivery penalty. The problem is
formulated as a nonlinear cost model which is minimized to arrive at an optimal
policy for reorder point, order quantity and number of shipments from the
vendor to the buyer. The solution procedure involves both closed form solution
and iterative search procedure. Numerical examples with potential industrial
implications are presented for uniform, exponential and normally distributed
lead-times.
4 - Two-step Gradient Search For Optimizing Biopharmaceutical
Supply Chain Decision-making

Motivated by our success in solving stochastic supply chain optimization problems
in the biopharmaceutical industry using retrospective optimization, we present a
two-step retrospective optimization-stochastic gradient search algorithm that in
initial empirical testing is both fast and effective. This method also allows us to
optimize policy parameters of complex supply chains with an assembly or
distribution structures subject to random demand, lead time and quality control
disruptions between stages.

2 - Political Risk In Supply Chain And Operations Management:
A Conceptual Model

, Aleda Roth
Political risk has been overlooked in the supply chain and operations
management literature while it remains one of the environmental factors that
influences the most operations and supply chains for foreign firms operating
abroad. We review the literature and propose an original conceptual model that
links risk causes to their potential consequences at the operational and supply
chain levels.
3 - The Impact Of Responsiveness On Supply Chain Risk A Heuristic
Method With Adaptive Genetic Algorithm

This paper examines the relationship between responsiveness, cost and supply
chain risk of disruptions. A conceptual model is developed to address flexibility,
agility, Internal Integration, visibility and responsiveness relationships, which are
further, examined using hypotheses testing. A heuristic algorithm based on
adaptive GA will be developed to solve NP hard problem.
4 - Financial And Order Strategies In A Supply Chain With
Option Contracts

We study a supply chain consisting of one supplier and one budget constraint
retailer who purchases from the supplier via an option contract. To satisfy the
stochastic customer demand, the retailer will order before the sales season and if
needed, she can a take bank credit financing (BCF) or trade credit financing (TCF)
to get enough working capital. After the sales season, the retailer should repay
the credit loan and interests with all the money in hand. To study the financial
and order strategies in the supply chain, we establish a Stackelberg game with the
supplier as the leader. The results show that the retailer’s order quantity is
affected by her wealth and both the supplier and retailer prefer the TCF.
5 - Structural Equation Model Of The Association O2O Platform
Between Service Supply Chain Risk And Vulnerability

Siping Road, Shanghai, 200092, China,
Abstract: Compared with the traditional supply chain, service supply chain is
possessed with the feature of intangibles and difficult to store, thus service supply
chain is more vulnerable. The present study used structural equation model based
on a large number of data to analyze which kind of service supply chain risk
would affect vulnerability typically. Studies have revealed that: demand risk
having a significant impact on the vulnerability of the service supply chain,
operational risk on service supply chain vulnerabilities affect the effect is not
significant. This study may provide theoretical guidance for service supply chain
risk and vulnerability relationship is of great significance.

1 - Impact Of Official Regulation Policies On Chinese Power Plant’s
Reusable Environmental Investments And Sustainable Operations

We analyze how Chinese coal-fired power plant’s reusable environmental
investments and sustainable operations would be influenced by different official
environment regulation policies. An empirical study of 27 mainland China’s
major million-KW coal-fired power plants is presented. With this empirical
analysis, we have answered following three questions: (1) what kind of reusable
environmental investment should be chosen by the coal-fired power plant, (2)
how to choose the “best” reusable environmental investment, and (3) what kind
of policy is better in China.
2 - Design Of Rainwater Harvesting And Greywater Recycling
Systems For Urban Areas
Juliana Arango, Graduate Student, Universidad de los Andes,
Bogotá, 111711, Colombia,
In urban areas, rainwater harvesting and greywater recycling systems provide
additional water supplies for houses, buildings, and industries, and mitigate
flooding events and pollution. This work proposes an optimization model for the
design of rainwater harvesting and greywater recycling systems (RHGRS) in
residential construction projects. Our methodology provides an optimal design of
the RHGRS, considering rainwater variability via stochastic programing. We apply
the model for a case study of low-income housing in Bogota (Colombia) with 696
apartments.
3 - Supply Chain Sustainability: A Case Study Based On The
Triple-bottom-line Perspective

, Qingyu Zhang
As the pressure of global energy conservation and public awareness of
environmental and social responsibility increase, sustainable development has
become a core problem of any manufacturing firm in managing their supply
chain. A case study was conducted to analyze the relationships among supply
chain exchange hazards, governance mechanisms, sustainability practices, and the
triple-bottom-line performance.
4 - Leadership And Collaboration For Supply Chain Sustainability
Jen-Yi Chen, Assistant Professor, Cleveland State University,
1860 E. 18th Street, Bu 545, Cleveland, OH, 44114, United States,
We analyze a firm’s decision on how to collaborate for more sustainable
operations by exploring the following two questions: What collaborative strategy
should the firm adopt? and How external market factors affect internal supply
chain strategic decisions? Managerial implications are discussed.
