6 - Quality Control Sampling in Continuous Production Sinan Obaidat, PhD Student, University of Arkansas, 1690 Live Oak Dr, Apt 12, Fayetteville, AR, 72704, United States, sfobaida@uark.edu, Haitao Liao In this study, a quality control sampling for continuous production is proposed. Items are sampled during the production process at specified intervals such that one item is inspected at each interval. The production process is stopped for maintenance if the number of nonconforming items found in sampling exceeds a certain acceptance limit. The production time is divided into sampling cycles of fixed sizes, but it is not necessary to complete a sampling cycle if the number of nonconforming items exceeds the acceptance limit. The objective of this paper is to find the parameters of the sampling plan: sampling interval, sampling size, and the acceptance limit to minimize the total cost of quality.

unclear. We collect data from a local clinic that has adopted this technology, and use it to evaluate the impact of continuous monitoring of blood pressure via smartphone app on the quality of patient care.

361A Topics in Behavioral Operations Management Sponsored: Behavioral Operations Management Sponsored Session Chair: Ruth Beer, Indiana University, Kelley School of Business, Bloomington, IN, 47404, United States, ruthbeer@indiana.edu 1 - Risk in Channels Paola Mallucci, University of Wisconsin, 4261 Grainger Hall, 975 University Avenue, Madson, WI, 53706, United States, mallucci@wisc.edu In a set of incentivized experiments we explore the role of risk in pricing decisions in a dyadic channel. We systematically vary who holds the risk while holding expected payoff constants across treatments. We find that subjects’ behavior is inconsistent with classical economic theories, risk aversion as well as theories of fairness. 2 - Auctions, Efficient Coordination, and Strategic Complementarities Anthony M. Kwasnica, Pennsylvania State University, 332 Business Bldg, University Park, PA, 16802, United States, kwasnica@psu.edu, James Fan The likelihood of auctions to lead to efficient outcomes in order statistic coordination games as originally studied by Van Huyck et al. (1993) is re- examined under varying conditions. Specifically, we examine whether minimum order statistic games results in similarly positive results to those originally found in median order statistic games. We find that coordination on the efficient outcome as a result of a pre-play auction is sensitive to the degree of strategic complementarity. Our results are examined in relation to the behavioral learning model proposed by Crawford and Broseta (1998). 3 - Wage Transparency in Sales Agents Compensation Schemes Javad Nasiry, Hong Kong University of Science and Technology- HKUST, Hong Kong, Hong Kong, nasiry@ust.hk, Xiaoyang Long Sales agents with social preferences evaluate their pay in comparison with their peers and experience a positive or negative utility. We characterize the optimal salesforce compensation schemes in this context and characterize the conditions under which wage transparency benefits the firm. 4 - Monitoring or Disclosure? the Role of Observability in Buyer- supplier Collaborative Projects Ruth Beer, Indiana University, Kelley School of Business, 314 W. 4th Street #404, Bloomington, IN, 47404, United States, ruthbeer@indiana.edu, Anyan Qi Many manufacturers’ projects (such as innovation and new product development) often involve tight collaboration with a key supplier. The success of such initiatives depends on both firms committing resources and generating high quality outputs. We study two ways in which a manufacturer can increase output observability (at a cost) in this setting: monitoring the supplier’s progress and disclosing her own progress to the supplier. 361B Behavioral Operations Contributed Session Chair: Sina Zare, University of Texas-Arlington, Arlington, TX, United States, sina.zare@uta.edu 1 - Suppliers Learning in Supply Chain Competition Mohsen Ahmadian, University of Massachusetts-Boston, Boston, MA, United States, mohsen.ahmadian001@umb.edu, Ehsan Elahi, Roger H. Blake Our research uses the results of laboratory experiments in which subjects playing the role of suppliers compete for the business of a buyer outsourcing the manufacture of a commodity product. These results show significant differences with predictions from theory, and our research uses the Quantal Response Equilibrium (QRE) to consider whether bounded rationality and learning effects can offer some explanation for these variances. By developing this model from the QRE framework, we will be able to evaluate learning effects and whether they vary under different scenarios of competition. WA49

Chair: Leon Cui, Binghamton University, 62 Decatur St, Binghamton, NY, 13903, United States, cui@binghamton.edu 1 - Improving Inventory Management of Perishable Substitutable Goods Gina Dumkrieger, ASU, Tempe, AZ, 85281, United States, gina.dumkrieger@asu.edu For families of perishable good where substitution is possible (such as blood products or antibiotics) outdating can be reduced through proactive use of substitution in the inventory allocation process. 2 - Managing Access To Care At Primary Care Facilities Sina Faridimehr, Wayne State University, 4815 Fourth Street, Manufacturing Engineering Building, Detroit, MI, 48202, United States, sina.faridimehr@wayne.edu, Saravanan Venkatachalam, Ratna Babu Chinnam One of the most important challenges confronting healthcare facilities is the effective management of access for patients to primary care. In this study, we develop appointment scheduling models using two-stage stochastic programming to improve access to care while maintaining high levels of provider capacity utilization and improving patient flow in clinic. 3 - Effectiveness of a Rapid Response Team in a Large Hospital: An Empirical Study. Valery Pavlov, Senior Lecturer, University of Auckland Business School, University of Auckland, Private Bag 92019, Auckland, 1142, New Zealand, v.pavlov@auckland.ac.nz, Ali Vahabzadeh In order to identify critically ill patients in the wards and timely transfer them to an ICU, and to prevent unnecessary ICU admissions, hospitals around the world have implemented Rapid Response Teams (also known as CCOT, MET or PAR teams). To date, the evidence on their effectiveness, coming exclusively from the medical literatures, has been scarce and controversial. One possible explanation is that these studies did not fully account for operational factors. Using a 12-month data from an 800-bed hospital in New Zealand, we investigate the impact of the hospital’s rapid response team on patient outcomes treating operational factors as instrumental variables. 4 - Systematic Layout Planning of A Radiology Reporting Area To Optimize Radiologists’ Performance Flavio S. Fogliatto, Associate Professor, Federal Univ of Rio Grande do Sul, Av. Osvaldo Aranha, 99/5o andar, Porto Alegre, RS, Optimizing radiologists’ performance is a major priority for managers of health services/systems, since the radiologists’ reporting activity imposes a severe constraint on radiology productivity. Despite that, methods to optimize radiologists’ reporting workplace layout are scarce in the literature. This study was performed in the Radiology Division (RD) of an 850-bed University-based general hospital. The analysis of the reporting workplace layout was carried out using the Systematic Layout Planning (SLP) method, in association with cluster analysis as a complementary tool in early stages of SLP. 5 - Improving Quality of Care At A Hypertension Clinic using A Mobile Health Application Leon Cui, Assistant Professor, Binghamton University, 62 Decatur St, Binghamton, NY, 13903, United States, cui@binghamton.edu, Saligrama Agnihothri, Anu Banerjee, Ramanujapuram Ramanujan Chronic conditions place a high cost burden on the healthcare system and deplete the quality of life for millions of Americans. To monitor their health, some hypertension patients now use mobile devices to measure blood pressure outside of the doctor’s office. These mobile health apps benefit patients by (i) yielding more accurate readings compared to in-office measurements, and (ii) offering timely information to the physician. However, the magnitude of this benefit is 90040020, Brazil, ffogliatto@producao.ufrgs.br, Carla Schwengber Ten Caten, Ricardo A. Cassel
