Models for the Sharing Economy

The sharing economy is used to denote emerging business models that enable the access to products and services on an on-demand basis. In some cases, this access is mediated by a digital platform that connects suppliers (often single individuals who are willing to share assets or provide a service) with buyers. Some of these platforms have been successful in overcoming the inefficiencies of peer-to-peer interactions by reducing transaction and search costs, facilitating payments, reducing moral hazard, and enabling trust among strangers. Others have been successful in harnessing economies of scale by tapping into idle assets or leveraging the crowd. These platforms present unique operational challenges regarding how best to match supply and demand, including pricing, wage setting, real time matching of buyers and suppliers, and the management of inventory and workforce, among others. They also raise important questions regarding the impact on consumers, incumbent firms, and society (e.g., environmental impact and impact on labor welfare).  In this tutorial, we describe recent efforts at developing models for the design, analysis, and optimization of these systems. In particular, we draw on three papers that consider (1) peer-to-peer product sharing, (2) labor platforms for on-demand services, and (3) product rental networks. We also discuss the many outstanding opportunities for operations and management science research in this area. (Based on joint work with Costas Courcoubetis, Jian-Ya Ding, Xiang Li, Xiaobo Li, Guangwen Kong, and Terry Taylor.)

Applications of Custom 3D Printed Physiological Heart Valve Models for Reducing Heart Surgery Risks

3D printing is finding more and more applications in medical fields, particularly personalized healthcare, due to its capabilities of producing patient-specific products, devices, and prototypes/models. This tutorial presents an innovative method of producing patient-specific, tissue-mimicking heart valves with sensing capability by integrating metamaterial design, multi-material 3D printing and printed electronics techniques. The physiological models can help surgeons or cardiologists make informed diagnosis, optimize surgery planning, and practice the operation prior to the surgery. In addition, the tissue-mimicking heart valves can provide effective means for surgeon training and patient education. This method is demonstrated through an application case of predicting post-surgery paravalvular leak of transcatheter aortic valve replacement (TAVR) procedure for treating aortic stenosis conditions. The 3D printed heart valve models were found to be effective in mimicking the valves of real patients for surgery outcome prediction. This tutorial will also present the ongoing research of this project: to explore the application of the virtual physiological models to augment the limited real patients data for developing machine learning-based predictive models to improve medical devices design, and diagnosis and treatment of certain medical conditions.

Research and Teaching Opportunities in Project Management

One-quarter of the world’s economic activity, with an annual value of $18 trillion, is organized using the business process of project management. This process has exhibited dramatic growth in business interest in recent years, with a more than 1000% increase in Project Management Institute membership since 1996. Contributing to this growth are new applications, for example IT implementations, research and development, software development, corporate change management, and new product and service development. However, the very different characteristics of modern projects present new challenges. The partial resolution of these challenges by industry over the last 15 years presents numerous interesting opportunities for academic researchers. These research opportunities make use of a remarkably broad range of methodologies, including robust optimization, cooperative and non-cooperative game theory, predictive analytics, and behavioral modeling. Furthermore, the $4.5 trillion that is annually at risk from a shortage of skilled project managers, and the 15.7 million new jobs in project management expected by 2020, provide great opportunities for contributions to project management education. These educational opportunities include the integration of case studies, analytics challenges, online simulations, in-class games, self-assessment exercises, videos, and guest speaker presentations, which form an appealing course for both business and engineering schools.

Model-Based Optimization for Operations Research: Best Practices and Current Trends

As optimization (or prescriptive analytics) has grown as a tool for business decision-making, a key factor in its success has been the adoption of model-based optimization. Using this approach, an analyst’s major work is to describe a problem of interest by means of an algebraic model, while the computation of a solution is left to general-purpose, off-the-shelf software. Powerful modeling systems manage the difficulties of translating between the human modeler’s ideas and the computer software’s needs. This tutorial introduces model-based optimization and offers a guide to its effective use.

Data Integrated Stochastics: Models and Methods

This tutorial will review the current data integrated approaches for predictive and prescriptive analysis of stochastic systems. In particularly we will review: 1) approaches such as Multi-Armed Bandit, Regularization in Sample Average Approximation and Data Driven Robust Optimization for generating prescriptive solutions to stochastic systems, and 2) some of the Machine Learning approaches used for predictive analysis of stochastic systems. We will then provide a framework for data integrated methodology for predictive and prescriptive analytics for stochastic systems. Specific attention will be paid to overcoming structural and statistical errors. This is achieved through Operational Statistics and Objective Operational Learning which are built on the basis of data integration and cross validation. We will illustrate how, 1) regularization in sample approximation approaches and data driven robust optimization with cross validation relates to Operational Statistics, and 2) multi-armed bandit and machine learning approaches compares to Objectives Operational Learning. Applications in pricing and revenue management, inventory control, queueing systems performance evaluation and staffing in service systems will be demonstrated.

The evolution of Supply chain function in the context of India

We document the evolution of two organizations in the complimentary area of Supply chain in the context of India. The first organization is in the commercial space selling consumables on a branded platform with multiple Stock keeping units. The presence in the multiple geographical markets over a period of time adds to the complex nature of the distribution function. The company has developed a extensive distribution network to meet the consumer expectation. Inventory management and order fill rate become the next set of priority areas. The co- ordination with sourcing of Raw material became critical for business advantage. Designing the marketing and sales schemes to support the supply chain function and gain market share was the next priority. Appropriate metrics were defined to evaluate and align the efficiency of the SCM operations. Using advances in ICT the organization has evolved a robust SC structure and systems. Today, the supply chain management principles of this organization is comparable to the best in world in FMCG segment.

The second origination is service provider in the area of logistics and supply chain. The growth of the organization is tracked with the changes in the environment in the Indian context. The innovative solutions adopted by the organization makes it vibrant and competitive. The entrepreneurial spirit of the organization keeping the changes in the opportunity land scape is captured. The customer centric measures add to the competitive positioning.

Both the stories are positioned in the overall context of research trends in SCM and the macro- economic environment in India. The central role played by ICT is highlighted.

Tales from the Crypt: Lessons Learned in Implementing Optimization Systems

Though the field of operations research was founded in practice, today there exists a substantial gap between its theoretical capabilities and real world impact. The field of operations research/management science/advanced analytics has never been more relevant than it is today. Our profession is in a unique position to solve the myriad problems that face our societies. The estimated $250 billion benefits generated by the by the 266 Edelman finalists since 1976, while very impressive, only represent the tip of the real savings produced by the operations research projects. Yet, a large number of systems are either never completed or fail to provide the full benefits. The never ending need for increased efficiency, availability of abundant data, and relatively inexpensive computing power makes it a golden age for the profession … provided we make use of the opportunity and deliver real world benefits. This interactive session will draw on the author’s more than 25 years of experience on implementing operations research systems and discuss the factors that contribute to the successful implementation and deployment of operations research systems.
