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.

Vortrag zu "Data driven Business Intelligence: From Predictive to Prescriptive Analytics" (Prof. O.P. Vyas, Indian Institute of Information Technology)

Veröffentlicht am 29. Mai 2019

Speaker: Prof. O.P. Vyas, Professor, Indian Institute of Information Technology, Allahabad-India 

Date: Wednesday 05.06.19 from 16:00 to 17:00
Place: FaKo Raum (U3-140)

Title: Data driven Business Intelligence: From Predictive to Prescriptive Analytics

Abstract:
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.

CfP for SI on "Modeling and Simulation of Complex Systems" in Annals of Operations Research

Veröffentlicht am 6. Juli 2018

Call for Papers for a Special Issue on "Modeling and Simulation of Complex Systems" in Annals of Operations Research

Submission Deadline: January 7th, 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:
http://www.springer.com/business+%26+management/operations+research/journal/10479

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).

Important Dates:
(*) Submission Start Date: July 1st, 2018
(*) Paper Submission Due: January 7th, 2019

Gastvortrag von Frau Dr. Sonja Radas (Institute of Economics in Zagreb)

Veröffentlicht am 24. Januar 2018

Frau Dr. Sonja Radas hat am 24. Januar einen Gastvortrag zum Thema "Uncovering Hidden Knowledge in Stated Purchase Intentions: Application of Bayesian Truth Serum" gehalten.

Abstract:
In new product development, purchase intention survey is often used for early sales forecasting and elimination of potentially failing concepts.
Regardless of its usefulness, it is known that there is a systematic discrepancy between stated purchase intentions and purchase incidence, resulting from both temporal and non-temporal causes. The latter, which are most often ascribed to systematic biases, are usually corrected by use of sophisticated statistical models which require large quantities of respondent and product related data.
In this paper we offer a new explanation for this discrepancy: we suggest that those respondents who are not sufficiently knowledgeable about the product report unreliable purchase intentions, which introduces noise in the predictions. So in order to improve forecasting precision, we propose to identify those respondents who are knowledgeable, isolate their purchase intentions and disregard the information from the others. This task is made more difficult by the fact that this knowledge is often tacit, especially for new products with higher degree of novelty.
We address this issue by building a theoretical model that can identify respondents who have tacit product related knowledge. Required data consists of answers to only two questions: (1) "will you buy the product", and (2) "what percentage of your peers will make the same choice as you". Having assumed that respondents themselves have private information about knowledgeable segments (which is invisible to the researcher), we employ the Bayesian Truth Serum methodology to uncover respondents’ belief structure.
