## Abstract The quality of life cycle inventory (LCI) data is crucial to the reliability of decisions made via life cycle analysis (LCA). However, many LCI data, be they from commercial software or public domain databases, violate the laws of thermodynamics due to errors, missing data, and other in

โฆ Synopsis
The purpose of the paper is to present a new model of the data l~fe-cycle. Such a model is needed to clarify activities involving data, from its creation through use, and to establish the relation-Ships of these activities to one another. The proposed model features four principal data cycles: the acquisition cycle includes activities that create and store data, the usage cycle includes activities that retrieve and use data, and the two kinds of the combined cycles incorporate both acquisition and usage activities. The model also includes quality checkpoints and feedback loops. These are particularly useful in clarifying data quality issues.

Quality of life data present considerable statistical challenges because of their longitudinal and multi- dimensional nature, and also because the available data are often very unbalanced through missing values. Here we exemplify the potential of multi-level models, that is, hierarchical random coe
This paper explores the practical application of life cycle assessment (LCA) to product system development. While life cycle assessment methods have been studied and demonstrated extensively over the last two decades, their application to product design and development has not been critically addres
Missing information on quality of life (QOL) is a significant problem in many cancer trials particularly for patients with advanced disease, where clinical deterioration may be a reason for not responding to quality of life assessments. Examples from four clinical trials are presented where non-resp
