Interaction patterns emerge as a solution for creating successful interactive systems, aiming mainly to solve a problem of an end-user interaction with a user interface, these patterns may be linked through the interaction pattern languages. Over time, various proposals have suggested such patterns, and its definition have been raised different formats describing patterns, in which the author is free to decide what elements or characteristics considered in its definition.This article is primarily concerned with showing how a template for defining patterns are selected. This is part of a research project that aims to propose a language interaction patterns for the design of software products focused on the user experience. To this end, it has carried out a conceptual review of some of the different formats describing patterns hitherto proposed and defined what elements or characteristics used, the findings have been compared with the application of a survey expert knowledge on the subject of patterns on the level of importance of the features found.
Supplier selection supported by methods based on computational tools are fundamental enterprise actions. This paper proposes the development of supplier selection model supported on a computational tool, using the purchasing department of Universidad Tecnológica de Bolívar as a case study. The review of different decision making techniques, yielded AHP as the most appropiate technique because of its multi-variable and multi-criteria capabilities. The design of the tool is based on Service Oriented Computing, as it allows easier integration, a better and faster response to process change and the environment changing needs. In this work, the design of the selection model, the identification and implementation of the services for selection and evaluation of suppliers were carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
