Feature Article: Optimization for simulation: Theory vs. Practice

Published Online:

INFORMS Journal on Computing

    Abstract
    Probably one of the most successful interfaces between operations research and computer science has been the development of discrete-event simulation software. The recent integration of optimization techniques into simulation practice, specically into ...
Design and Use of the Microsoft Excel Solver

Published Online:

Interfaces

    Abstract
    In designing the spreadsheet optimizer that is bundled with Microsoft Excel, we and Microsoft made certain choices in designing its user interface, model processing, and solution algorithms for linear, nonlinear, and integer programs. We describe some of ...
Defending Critical Infrastructure

Published Online:

Interfaces

    Abstract
    We apply new bilevel and trilevel optimization models to make critical infrastructure more resilient against terrorist attacks. Each model features an intelligent attacker (terrorists) and a defender (us), information transparency, and sequential actions ...
Developing and Validating Trust Measures for e-Commerce: An Integrative Typology

Published Online:

Information Systems Research

    Abstract
    Evidence suggests that consumers often hesitate to transact with Web-based vendors because of uncertainty about vendor behavior or the perceived risk of having personal information stolen by hackers. Trust plays a central role in helping consumers ...
A Partial Least Squares Latent Variable Modeling Approach for Measuring Interaction Effects: Results from a Monte Carlo Simulation Study and an Electronic-Mail Emotion/Adoption Study

Published Online:

Information Systems Research

    Abstract
    The ability to detect and accurately estimate the strength of interaction effects are critical issues that are fundamental to social science research in general and IS research in particular. Within the IS discipline, a significant percentage of research ...
Determinants of Perceived Ease of Use: Integrating Control, Intrinsic Motivation, and Emotion into the Technology Acceptance Model

Published Online:

Information Systems Research

    Abstract
    Much previous research has established that perceived ease of use is an important factor influencing user acceptance and usage behavior of information technologies. However, very little research has been conducted to understand how that perception forms ...
Measuring the Customer Experience in Online Environments: A Structural Modeling Approach

Published Online:

Marketing Science

    Abstract
    Intuition and previous research suggest that creating a compelling online environment for Web consumers will have numerous positive consequences for commercial Web providers. Online executives note that creating a compelling online experience for cyber ...
Using Online Conversations to Study Word-of-Mouth Communication

Published Online:

Marketing Science

    Abstract
    Managers are very interested in word-of-mouth communication because they believe that a product's success is related to the word of mouth that it generates. However, there are at least three significant challenges associated with measuring word of mouth. ...
Information Distortion in a Supply Chain: The Bullwhip Effect

Published Online:

Management Science

    Abstract
    Consider a series of companies in a supply chain, each of whom orders from its immediate upstream member. In this setting, inbound orders from a downstream member serve as a valuable informational input to upstream production and inventory decisions. This ...
A Theoretical Extension of the Technology Acceptance Model: Four Longitudinal Field Studies

Published Online:

Management Science

    Abstract
    The present research develops and tests a theoretical extension of the Technology Acceptance Model (TAM) that explains perceived usefulness and usage intentions in terms of social influence and cognitive instrumental processes. The extended model, ...
The Digitization of Word of Mouth: Promise and Challenges of Online Feedback Mechanisms

Published Online:

Management Science

    Abstract
    Online feedback mechanisms harness the bidirectional communication capabilities of the Internet to engineer large-scale, word-of-mouth networks. Best known so far as a technology for building trust and fostering cooperation in online marketplaces, such as ...
Coordination and Flexibility in Supply Contracts with Options

Published Online:

M&SOM

    Abstract
    We investigate the role of options (contingent claims) in a buyer-supplier system. Specifically using a two-period model with correlated demand, we illustrate how options provide flexibility to a buyer to respond to market changes in the second period. We ...
Robust Convex Optimization

Published Online:

Mathematics of OR

    Abstract
    We study convex optimization problems for which the data is not specified exactly and it is only known to belong to a given uncertainty set U, yet the constraints must hold for all possible values of the data from U. The ensuing optimization problem is ...
Branch-and-Price: Column Generation for Solving Huge Integer Programs

Published Online:

Operations Research

    Abstract
    We discuss formulations of integer programs with a huge number of variables and their solution by column generation methods, i.e., implicit pricing of nonbasic variables to generate new columns or to prove LP optimality at a node of the branch-and-bound ...
The Price of Robustness

Published Online:

Operations Research

    Abstract
    A robust approach to solving linear optimization problems with uncertain data was proposed in the early 1970s and has recently been extensively studied and extended. Under this approach, we are willing to accept a suboptimal solution for the nominal ...
Organizing and the Process of Sensemaking

Published Online:

Organization Science

    Abstract
    Sensemaking involves turning circumstances into a situation that is comprehended explicitly in words and that serves as a springboard into action. In this paper we take the position that the concept of sensemaking fills important gaps in organizational ...
Deliberate Learning and the Evolution of Dynamic Capabilities

Published Online:

Organization Science

    Abstract
    This paper investigates the mechanisms through which organizations develop dynamic capabilities, defined as routinized activities directed to the development and adaptation of operating routines. It addresses the role of (1) experience accumulation, (2) ...
Prospering in Dynamically-Competitive Environments: Organizational Capability as Knowledge Integration

Published Online:

Organization Science

    Abstract
    Unstable market conditions caused by innovation and increasing intensity and diversity of competition have resulted in organizational capabilities rather than served markets becoming the primary basis upon which firms establish their long-term strategies. ...
Service-Dominant Logic as a Foundation for Service Science: Clarifications

Value Cocreation and Service Systems (Re)Formation: A Service Ecosystems View

Published Online:

Service Science

    Abstract
    This article explores a service-dominant (S-D) logic, service-ecosystems approach to studying value cocreation and the (re)formation of service systems. We outline the central premises of S-D logic and elaborate the concept of a service ecosystem to ...
Evolution Cum Agency: Toward a Model of Strategic Foresight
