Title: Integration of Machine Learning and Optimization for Supply Chain Optimization
Abstract: We are trying to develop the AI techniques that can be explained by an automatic synthesis of decision-making models through the integration of machine learning and optimization. By constructing a feedback loop of machine learning and optimization, a closed-loop data-driven system that can improve the machine learning accuracy and significantly reduce the computational time required for optimization through machine learning methods even in a shortage of teaching data. From the viewpoint, our recent topics on dynamic multi-commodity network design problem, virtualization of supply chains, mass customization of product design and supply chain planning, inverse optimization for scheduling problems, imitative learning will be discussed.

Title: Platform Operations Research: Foundations and the Cases of Coup Scooter Sharing and Quicargo Collaborative Trucking
Abstract: Over the last decade, platforms have emerged in numerous industries and often transformed them, which poses new challenges for operations research. Platform providers mostly do not have immediate control over the physical resources to move people or goods. They often operate in a multi-sided market setting where it is crucial to design clear incentives to motivate a third-party to engage in an adhoc kind of collaboration. As a consequence, collaboration incentives become an integral part of decision support models for platform providers, and they need to be developed on an operational planning level to be applied in a dynamic way. Naturally, this involves a trade-off between the interests of platform provider, customers, and various transportation service providers. In this work, we investigate the real-word case of Coup scooter sharing and propose a dynamic pricing approach that engages users in fleet management operations such as charging and repositioning of vehicles. First results indicate that this approach effectively increases vehicle utilization and revenues. As a second real-world case, we look at the platform provider, Quicargo, who operates as an intermediary between shippers and carriers in a less-than-truckload (LTL) business. We introduce a planning model that minimizes the price this platform pays to its carriers and enforces collaboration incentives for carriers. We explore possible policies to be implemented by the platform and find that their business even remains profitable when the platform guarantees increased profit margins to their carriers as incentives.

Title: Data driven Business Intelligence: From Predictive to Prescriptive Analytics
Business Data analytics has gathered a lot of attention during the last years. Although descriptive and predictive analytics have become well-established areas, prescriptive analytics has just started to emerge with a different paradigm. Prescriptive analytics aims to prescribe decisions on the basis of the predictive analytics outcomes and involves an interdisciplinary approach with advances from Optimization and Decision Sciences.
Referred to as the "final frontier of analytic capabilities," prescriptive analytics suggests decision options to take advantage of the results of descriptive and predictive analytics. Prescriptive Analytic approaches propose to help businesses make better decisions by factoring in knowledge of possible situations, available resources, past performances and current happening as well.
The Prescriptive Analytics assumes special significance as the huge amount of Businesses moving from traditional "brick and mortar" shops to Online Enterprises warranting to have recommendations in rather more prescriptive ways. The proposed talk aims at exploring the opportunity and challenges involved, owing to introduction of "optimization" in "Business Analytics" arena with the novel paradigm of Prescriptive Analytics.

Is more autonomous always better? - Aufsatz im International Journal of Automotive Technology and Management zur Publikation angenommen
Wünschen sich Konsumenten tatsächlich vollständig autonome Autos? Dies wird in einem eben zur Publikation angenommenen Zeitschriftenaufsatz anhand von drei ausgewählten Funktionalitäten untersucht. Dabei zeigt sich, dass (derzeit) ein mittlerer Grad an Autonomie gegenüber vollständiger Autonomie fast immer bevorzugt wird. Der Beitrag mit dem Titel "Is more automation always better? An empirical study of customers' willingness to use autonomous vehicle functions" (von Mohamed Souka, Daniel Böger, Reinhold Decker, Christian Stummer und Alisa Wiemann) wird im International Journal of Automotive Technology and Management (IJATM) erscheinen.
Das IJATM ist im Journal-Ranking JourQual3 des Verbands der Hochschullehrer für Betriebswirtschaft als C-Publikation und damit als anerkannte wissenschaftliche Zeitschrift eingestuft.
Am Institut für Technologische Innovation, Marktentwicklung und Entrepreneurship ist aktuell eine Stelle als Studentische bzw. Wissenschaftliche Hilfskraft (SHK/WHF) ausgeschrieben. Alle Informationen zur Ausschreibung finden Sie im Aushang.
Deadline extension for special issue on "Modeling and Simulation of Complex Systems" in Annals of Operations Research (now: Feb. 28, 2019)
Call for Papers for a Special Issue on "Modeling and Simulation of Complex Systems" in Annals of Operations Research
Submission Deadline: February 28th, 2019
Complex systems are a common phenomenon in real-world decision making. The behavior of such a complex system stems from numerous relationships and various interactions between diverse entities of the system or between a given system and its environment: innovation diffusion on consumer markets may serve as an example. Computer simulations provide an opportunity to alter a modeled system, to observe its emergent behavior, and, thus, to answer what-if questions.
This special issue of the Annals of Operations Research aims at discussing recent advances in modeling and simulation of complex systems. Methods to be applied include agent-based simulation, multi-agent systems, simulation-optimization approaches, etc. Potential topics to consider (but not limited to) are:
(*) diffusion processes in markets, societies, or ecosystems
(*) applications in various areas including, for example, smart products, smart production systems, or autonomous production
(*) impact of peculiarities of some complex system, e.g., word of mouth or social influence
(*) parametrization and validation issues
We hope the special issue will document the state-of-the-art in modeling and simulation of complex systems and provide a framework for future research that moves the field forward by better solving relevant problems with more realistic assumptions, and by leveraging the best research in related disciplines. Researchers from all disciplines are invited to consider this special issue as an outlet to publish their high quality work on the above or related topics.
Instructions for authors can be found at:
Authors should submit their manuscripts via the Journal’s online submission site (http://www.editorialmanager.com/anor/), choosing “S.I.: Simulating Complex Systems” as the article type. All papers submitted to the special issue will be peer reviewed in accordance with the standard procedures of the Annals of Operations Research journal.
Submitted papers should not have been previously published or be currently under consideration for publication elsewhere. Papers must contain original research results that are significant relative to the relevant literature.
The use of real-world data is valued. Still, submitted papers must highlight their (algorithmic) contribution to the state of the art in this field of operations research and they should discuss some simulation experiments (i.e., numerical illustrations (examples) may not be sufficient).
(*) Submission Start Date: July 1st, 2018
(*) Paper Submission Due: February 28th, 2019 (extended deadline)
