Flexible Data Driven Inventory Management with Interactive Multiobjective Lot Size Optimization
2021
We study data-driven decision support and formalise a path from data to decision making. We focus on lot sizing in inventory management with stochastic demand and propose an interactive multi-objective optimisation approach. We forecast demand with a Bayesian model, which is based on sales data. After identifying relevant objectives relying on the demand model, we formulate an optimisation problem to determine lot sizes for multiple future time periods. Our approach combines different interactive multi-objective optimisation methods for finding the best balance among the objectives. For that, a decision maker with substance knowledge directs the solution process with one’s preference inform…
Mobile Banking and Payment System : A Conceptual Standpoint
2017
This study conceptualizes and proposes a well-regulated and designated mobile banking and payment system (MBPS) with the potential to strengthen the banking system, foster the regulatory framework, and to be integrated across various platforms and mobile devices. Unlike other mobile payment systems that lack convenience, scalability, and usability, the proposed MBPS contains several important functionalities and it has the potential to bring together hitherto unconnected industries—banking, Fintech and telecoms—to offer value-added services to their existing and potential customers. The ownership of the MBPS shall remain with the financial services sector including the banking and microfina…
User participation in knowledge update of expert systems
1997
Abstract Applying the Elaboration Likelihood Model (ELM) of persuasion we conducted an experiment to examine the effect of participation of users in the design process on their acceptance of system recommendations and revision of their original decisions. Results of our study indicate that two different types of information processing occur when subjects are reviewing the expert system recommendations. 1. (i) For users who have a high perceived level of participation in updating the knowledge of the ES, ambiguity of the decision setting is the primary determinant affecting acceptance of the recommendation from the ES. 2. (ii) For users who have a low perceived level of participation in upda…
The problem and the solution of accounting in a text
1993
Abstract An interpretative reading of accounting texts published in management accounting journals is offered. The selected articles were read many times, but the phenomenological hermeneutic description is developed through a process of “three readings.” The first reading proposes that the texts share a pattern of preach: They start with an introduction, describe a failing accounting, and remind the reader that through change, better accounting is achievable. In the second reading it is noticed, however, that the idea of “defining a problem and finding a solution with the help of accounting” receives a very different expression in different articles. Consequently, the third reading suggest…
Polynomial Regression and Measurement Error
2020
Many of the phenomena of interest in information systems (IS) research are nonlinear, and it has consequently been recognized that by applying linear statistical models (e.g., linear regression), we may ignore important aspects of these phenomena. To address this issue, IS researchers are increasingly applying nonlinear models to their datasets. One popular analytical technique for the modeling and analysis of nonlinear relationships is polynomial regression, which in its simplest form fits a "U-shaped" curve to the data. However, the use of polynomial regression can be problematic when the independent variables are contaminated with measurement error, and the implications of error can be m…
Implementing collaborative governance: models, experiences, and challenges
2021
This paper introduces the reader to a special issue focused on Collaborative Governance implementation. The purpose of this symposium is to advance our understanding of the cross-cutting and complex issues of collaborative governance implementation, which include: (a) supporting the collaborative process through innovative models and methods for enhancing a shared understanding of community problems and outcomes, (b) fostering the interplay between service policy and service delivery, and (c) combining a public service view with an institutional and interinstitutional view
Quality Indicators for Crisis Communication to Support Emergency Management by Public Authorities
2011
The purpose of this paper is to develop a framework for performance indicators to measure and improve crisis communication preparedness of public authorities. Such an instrument supporting organizational learning has not yet been developed for crisis communication. Literature is used to create a basis and the framework is derived from a process model with various phases integrating communication activities with crisis management. In the paper, the development of the instrument is explained and justified. Furthermore, an example of its use is provided in which the instrument is used for an auditor evaluation of a water contamination case. A next step for future research could be to analyze a…
Combining system dynamics modelling and management control systems to support strategic learning processes in SMEs: a Dynamic Performance Management …
2015
Traditional management control systems, mainly centred on accounting-based measures, are widely recognized as useful tools to support Small and Medium Enterprises (SMEs) managers and entrepreneurs in steering business development. However, due to the increasing turbulence and dynamic complexity that characterize today’s competitive arenas, such systems need to be combined with simulation-based methodologies in order to improve entrepreneurial learning processes and, as a result, better detect possible crisis symptoms and weak signals of change—emerging from the business environment—to promptly react. Therefore, the aim of this paper is to show how a combination of traditional management con…
Innovative IC framework in the non profit sector
2012
The importance of intellectual capital in the non-profit sector generates the need to measure its role in the value creation process. The purpose of the paper is to study the application of intellectual capital within the non-profit sector, by turning attention to resources such as: knowledge, experience, and skills. Organizations, which are able to increase the knowledge of their staff and transform this knowledge into skills to improve services, can easily meet users’ needs and, thereby, become competitive. This contribution proposes to study how people’s knowledge can contribute to increasing social value, which is the non–profit organization’s aim. Furthermore, the goal is to de…
Components of software development risk: how to address them? A project manager survey
2000
Software risk management can be defined as an attempt to formalize risk oriented correlates of development success into a readily applicable set of principles and practices. By using a survey instrument we investigate this claim further. The investigation addresses the following questions: 1) What are the components of software development risk? 2) how does risk management mitigate risk components, and 3) what environmental factors if any influence them? Using principal component analysis we identify six software risk components: 1) scheduling and timing risks, 2) functionality risks, 3) subcontracting risks, 4) requirements management, 5) resource usage and performance risks, and 6) person…
