The purpose of this study is to understand and analyze the impacts of visitor background variable, travel fair attraction, experience, and satisfaction on visitor loyalty at the Taipei International Travel Fair. Subjects were visitors who attended the 2010 Taipei International Travel Fair. Convenience sampling was conducted at the fair exit. A total of 150 surveys were performed each day. Out o...

The visitor pattern, a well known Gang of Four design pattern, provides a suitable way to add operational behaviour to models. However, as soon as the number of metamodels and visitor implementations start to grow, some of the pattern shortcomings make its usage less convenient. This paper presents how the synergy between the Visitor pattern and MDE has been addressed by two open source project...

This paper descrihes the development and application of a computer-based simulation model of recreational use in the John Muir Wilderness Area in the Sierra Nevada Mountains of California, USA. The results of the study demonstrate, conceptually, how sitnulation modelitig can be used as a tool for understanding existing visitor use patterns within the John Muir Wilderness Area, estimating the im...

For object-oriented programming, the Visitor pattern enables the definition of a new operation on an object structure without changing the classes of the objects. The price has been that the set of classes must be fixed in advance, and they must each have a so-called accept method. In this paper we demonstrate how to program visitors without relying on accept methods and without knowing all cla...
