-prone classes. This study is complementary to [Li&Henry, 1993] where the same suite of metrics had been used to assess frequencies of maintenance changes to classes. To perform our validation accurately, we collected data on the development of eight medium-sized information management systems based

of the individual or his family different from that which exists in the present, as, for example, in relation to old age, family education, or the maintenance of dependents. " These motives, in contrast to most of the previous ones, have the

Abstract: General aspects of sustainable decision making are investigated and a possible formulation of socio-economical sustainable decision making is illustrated on the problem of life-cycle based design and maintenance of civil engineering facilities. First an overview is given on the present

Abstract. Maintenance personnel training is typically a mixture of instructor led courses, Computer Based Training (CBT), hardware training devices and on-the-job training. However, because of reduced training budgets, limited access to live equipment, and expensive hard trainers, this training

In comparison with the well-researched field of analysis and design of structural systems, the life-cycle performance prediction of these systems under no maintenance as well as under various maintenance scenarios is far more complex, and is a rapidly emergent field in structural engineering

AbstractÐSoftware merging is an essential aspect of the maintenance and evolution of large-scale software systems. This paper provides a comprehensive survey and analysis of available merge approaches. Over the years, a wide variety of different merge techniques has been proposed. While initial

The simulation of building efficiency and cost is a crucial driver to contemporary building design today. This paper presents the development of a software tool to simulate the lifecycle costs of building construction and maintenance. It is a part of the nD modelling tool development and also based

processes, such as committees, to tackle the problem or develop the opportunity. In the fourth stage, the gains are consolidated through the maintenance of the linkages. Processes and resources are put in place to facilitate the effective management of the linkages. In the management and sustainability

not adequately support the management of process variants. Usually, the variants have to be kept in separate process models. This leads to huge modeling and maintenance efforts. In particular, more fundamental process changes (e.g., changes of legal regulations) often require the adjustment of all process

This research project has provided improved maintenance resource data for use during facility planning, design, and maintenance activities. *T C Data bases and computer systems have been developed to assist planners in preparing DD Form 1391 documentation, designers in life-cycle.F E T cost
