In manufacturing, great gains in performance have been realized by a new production philosophy, which leads to "lean production". This new production philosophy is a generalization of such partial approaches as JIT, TQM, time-based competition, and concurrent engineering. In construction, lean production is little known. The concepts, principles and methods of lean production are reviewed, and ...

The Highways Agency (HA) has recently rethought the way it commissions maintenance work on the trunk roads and motorways for which it is responsible. Taking on recommendations from recent reports into the UK construction industry, the HA have introduced the Construction Management Framework (CMF) in Areas 9 and 10 which covers a large area of the UK from Herefordshire to Lancashire. The CMF loo...

Knowledge engineering, knowledge management and conceptual modelling are concerned with representing knowledge of business and organizational domains. These research areas use ontologies for knowledge representation. Ontologies are understood either in the philosophical sense as firm metaphysical commitments or in the looser sense of dictionaries or taxonomies. This paper critically examines th...

The objective of this research is to develop a turbine blade investment casting cost advisor model to assist a blade designer in decision-making in a concurrent engineering environment. It is a microcomputer based cost estimating system that employs a manufacturing knowledge base. The concept of the manufacturing process for blade production by the investment casting method is used to develop t...

This paper discusses how a process-centered knowledge management and coordination support approach can be used to create learning software organizations. We describe our extensions to the software engineering environment MILOS that allow us to model and interpret information needs that occur during project planning and enactment; this enables MILOS to automatically provide users with task-speci...

Aimed at maximizing project value while reducing waste and cost, the lean construction (LC) approach was formally successfully introduced to architecture, engineering (AEC) industry in 1993. Although LC has rapidly developed since that time, it not applied a Chinese until 2005. However, due insufficient knowledge poor execution, this first attempt China inadequate. The aim of study therefore di...

the aim of this paper is to determine the use of lean management components in the libraries of medical sciences universities in the north provinces of iran. the methodology is a cross-sectional survey in which the viewpoints of 105 managers and employees in different units of libraries of medical sciences universities are evaluated in mazandaran, golestan, and gilan to determine the applicatio...

expert systems are computer programs that make the knowledge of experts available when a human expert is not with in easy reach. the systems are to simulate the thinking and inference pattern of human being. the ultimate goal of expert system is to be analogous to human as much as possible. utilizing the intelligent system in commerce is indispensable for establishing a better connection with c...

There is a large and growing body of knowledge regarding so-called Lean best practices, including most recently in the area of program management and systems engineering. However, there is little elaboration of how these documented best practices are to be introduced to a professional workforce. One way of introducing new practices to a workforce is through the use of training workshops, but th...

This paper investigates the differences in timelines involved Lean Six Sigma (LSS) project deployment a regulated industry versus an unregulated one. Two case studies utilising methods—in order to compare transfer of manual manufacturing lines within medical device and electronics site—are discussed utilised. research aims show effects regulatory procedures on LSS implementation timelines. stud...
