3 - Vendor-buyer Cooperative Policy With Penalty For Late Delivery Md Shahriar Jahan Hossain, Graduate Assistant, Louisiana State University, 2508 Patrick F. Taylor Hall, Baton Rouge, LA, 70803, United States, msjhossain1@gmail.com, Mohamed M. Ohaiba, Bhaba R Sarker 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 Stewart Liu, PhD Candidate, Univeristy of California-Berkeley, 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.

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 Seyed Vahid Reza Nooraie, NC A&T State University, Greensboro, NC, United States, snooraie@aggies.ncat.edu, Mahour Mellat parast, Paul M Stanfield, Saeed Zamiri Marvizadeh 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 Shengya Hua, Peking University, Room 121, Building 1, ChangChun Xin Yuan, Peking University, Yiheyuan Road No.5, Haidian District, Beijing, 100871, China, huasy@pku.edu.cn, Xin Zhai 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. 4141 Etcheverry Hall, MC 1777, Berkeley, CA, 94720, United States, stewart_liu@berkeley.edu, Philip Kaminsky

5 - Structural Equation Model Of The Association O2O Platform Between Service Supply Chain Risk And Vulnerability Iris Luan, Tongji University, Rm 611, Tongji Buildding A, No.1500 Siping Road, Shanghai, 200092, China, luanxiaoxi@163.com 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.

Chair: Jen-Yi Chen, Assistant Professor, Cleveland State University, 1860 E. 18th Street, Bu 545, Cleveland, OH, 44114, United States, j.chen27@csuohio.edu 1 - Impact Of Official Regulation Policies On Chinese Power Plant’s Reusable Environmental Investments And Sustainable Operations Xiang Ji, School of Management, University of Science and Technology of China, Hefei, China, signji@mail.ustc.edu.cn, Jiasen Sun 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, j.arango905@uniandes.edu.co 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 Mei Cao, University of Wisconsin-Superior, Belknap & Catlin, P.O. Box 2000, Superior, WI, 54880-4500, United States, mcao1@uwsuper.edu, 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, j.chen27@csuohio.edu 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.
