This paper presents a general model to assess the impact of data and process quality upon the outputs of multi-user information-decision systems. The data flow/data processing quality control model is designed to address several dimensions of data quality at the collection, input, processing and...

Appropriate inspection is a significant component of production systems. In this paper a model is developed to determine the optimal placement of inspection stations within n-stage linear production systems. This model accommodates two types of inspector fallibility: "predictable," which implies...

Intermediate and long range planning for Departments of Transportation necessitates the estimation of the cost of bridge rehabilitation, a range of activities falling between maintenance and replacement. This paper presents a set of regression models designed within the context of data available...

The use of mathematical models in transportation and regional planning is limited by the need to obtain reasonably accurate, complete data sets. In particular complete spatial coverage is required for the usual discrete origin-destination models. Because of the time and cost constraints of...

The failure of many IS development efforts suggests that the development process, in particular the role that key antecedents play in ensuring success, is poorly understood. Information systems are based on a series of highly complex interrelated tasks that can be significantly affected by...
