Book Description
We study a fundamental online resource allocation problem in service operations in which a heterogeneous stream of arrivals that vary in service times and rewards make service requests from a finite number of servers/providers. This is an online adversarial setting in which nothing more is known about the arrival process of customers. Each server has a finite regular capacity but can be expanded at the expense of overtime cost. Upon arrival of each customer, the system chooses both a server and a time for service over a scheduling horizon subject to capacity constraints. The system seeks easy-to-implement online policies that admit a competitive ratio (CR), guaranteeing the worst-case relative performance. On the academic side, we propose online algorithms with theoretical CRs for the problem described above. On the practical side, we investigate the real-world applicability of our methods and models on appointment-scheduling data from a partner health system. We develop new online primal-dual approaches for making not only a server-date allocation decision for each arriving customer but also an overtime decision for each server on each day within a horizon. We also derive a competitive analysis to prove a theoretical performance guarantee. Our online policies are (i) robust to future information, (ii) easy-to-implement and extremely efficient to compute, and (iii) admitting a theoretical CR. Comparing our online policy with the offline optimal policy, we obtain a CR which guarantees the worst-case performance of our online policy. We evaluate the performance of our online algorithms by using real appointment scheduling data from the UMHS. Our results show that the proposed online policies perform much better than their theoretical CR, and outperform the pervasive First-Come-First-Served (FCFS) and nested threshold policies (NTPO) by a large margin.

Book Description
“Brigid Schulte is a vital voice on the future of work, and her carefully researched book lights the way to fewer hours, less stress, and more meaning.” ―Adam Grant, #1 New York Times bestselling author of Think Again and Hidden Potential, and host of the podcast WorkLife From the New York Times bestselling author of Overwhelmed, a deeply reported exploration of why American work isn’t working and how our lives can be made more meaningful Following Overwhelmed, Brigid Schulte’s groundbreaking examination of time management and stress, the prizewinning journalist now turns her attention to the greatest culprit in America’s quality-of-life crisis: the way our economy and culture conceive of work. Americans across all demographics, industries, and socioeconomic levels report exhaustion, burnout, and the wish for more meaningful lives. This full-system failure in our structure of work affects everything from gender inequality to domestic stability, and it even shortens our lifespans. Drawing on years of research, Schulte traces the arc of our discontent from a time before the 1980s, when work was compatible with well-being and allowed a single earner to support a family, until today, with millions of people working multiple hourly jobs or in white-collar positions where no hours are ever off duty. She casts a wide net in search of solutions, exploring the movement to institute a four-day workweek, introducing Japan’s Housewives Brigade—which demands legal protection for family time—and embedding with CEOs who are making the business case for humane conditions. And she demonstrates the power of a collective and creative demand for change, showing that work can be organized in an infinite number of ways that are good for humans and for business. Fiercely argued and vividly told, rich with stories and informed by deep investigation, Over Work lays out a clear vision for ending our punishing grind and reclaiming leisure, joy, and meaning.

Book Description
Despotism on Demand draws attention to the impact of flexible scheduling on managerial power and workplace control. When we understand paid work as a power relationship, argues Alex J. Wood, we see how the spread of precarious scheduling constitutes flexible despotism; a novel regime of control within the workplace. Wood believes that flexible despotism represents a new domain of inequality, in which the postindustrial working class increasingly suffers a scheduling nightmare. By investigating two of the largest retailers in the world he uncovers how control in the contemporary "flexible firm" is achieved through the insidious combination of "flexible discipline" and "schedule gifts." Flexible discipline provides managers with an arbitrary means by which to punish workers, but flexible scheduling also requires workers to actively win favor with managers in order to receive "schedule gifts": more or better hours. Wood concludes that the centrality of precarious scheduling to control means that for those at the bottom of the postindustrial labor market the future of work will increasingly be one of flexible despotism.

Book Description
The logic of Manufacturing Resource Planning (MRP II) is usually implemented in production planning and control systems and therefore has a major impact on the performance of many real production systems. Much of what practitioners complain about, i.e. long lead times, high work-in-process, and large inventories, is due to the deficiencies of the MRP II concept. Thus, researchers are eager to find better models and methods to improve or to replace the current status. This book contains new ideas on master production scheduling, material requirements planning, lot sizing, sequencing and scheduling, and production control. Management scientists, industrial engineers, operations researchers, and computer scientists have contributed to present the state-of-the-art.
