Mozambique A Non-Parametric Extension to the Threshold Model Bjorn Van Campenhout One of the main drawbacks of current methods to measure market integration is the assumption of constant transaction costs. In this paper, we propose a non-parametric extension to the commonly used threshold models, allowing us to estimate transaction costs in a more flexible way. We illustrate the method using we...

The paper presents a framework, in which the main concepts of schema and data integration can be specified both semantically and syntactically in an abstract data-model independent way. We first define what are schema matching and integration semantically, in terms of sets of instances and mappings between them. We also define a schema matching and integration syntactically, and introduce a pro...

Dieser Artikel befasst sich mit der kausalitätsbasierten Modellierung von Software-Entwicklungsprozessen. Damit soll die tatsächliche Situation im SoftwareProzessfeld transparenter werden. Ein erster Überblick über existierende Ansätze für kausale Netzwerke zeigt dabei die Probleme und den möglichen Nutzen des Einsatzes dieser formalen Techniken im Bereich der Softwareentwicklung. Die Definitio...

Managing complexity in developing enterprise-spanning applications is still a challenge. A vital field of delivering technical concepts and technologies to support interoperability in business systems is the area of Enterprise Application Integration (EAI). In modelling and developing large enterprise applications, it is necessary to integrate applications on the business and conceptual level a...

In this paper, it was an attempt to be present a practical perishability inventory model. The proposed model adds using spoilage of products and variable prices within a time period to a recently published location-inventory-routing model in order to make it more realistic. Aforementioned model by integration of strategic, tactical and operational level decisions produces better results for sup...
