The interaction of lean and building information modeling in construction
Lean construction and Building Information Modeling are quite different initiatives, but both are having profound impacts on the construction industry. A rigorous analysis of the myriad specific interactions between them indicates that a synergy exists which, if properly understood in theoretical terms, can be exploited to improve construction processes beyond the degree to which it might be improved by application of either of these paradigms independently. Using a matrix that juxtaposes BIM functionalities with prescriptive lean construction principles, fifty-six interactions have been identified, all but four of which represent constructive interaction. Although evidence for the majority of these has been found, the matrix is not considered complete, but rather a framework for research to
explore the degree of validity of the interactions. Construction executives, managers, designers and developers of IT systems for construction can also benefit from the framework as an aid to recognizing the potential synergies when planning their lean and BIM adoption strategies
A method to Formalise the Rapid Prototyping Process
Facing the increasing complexity of the product design area, (reduction of cycle times, introduction of simultaneous engineering, introduction of digital mock-up, ... ) a research department which wants to define a rapid prototyping process is confronted to the problem of the toolsâ choice. Therefore, we will propose in this article, a method allowing to conceive such a process. In a first chapter, we present the rapid prototyping area in the product design environment, in a second chapter we will propose our method illustrated by an industrial case
Enabling decentral collaborative innovation processes - a web based real time collaboration platform
The main goal of this paper is to define a collaborative innovation process
as well as a supporting tool. It is motivated through the increasing
competition on global markets and the resultant propagation of decentralized
projects with a high demand of innovative collaboration in global contexts. It
bases on a project accomplished by the author group. A detailed literature
review and the action design research methodology of the project led to an
enhanced process model for decentral collaborative innovation processes and a
basic realization of a browser based real time tool to enable these processes.
The initial evaluation in a practical distributed setting has shown that the
created tool is a useful way to support collaborative innovation processes.Comment: multikonferenz wirtschaftsinformati
The integration of process planning and machine loading in small batch part manufacturing
PART is a highly automated planning system in which both process and production planning functions are integrated. This paper discusses a method to improve machine tool selection in process planning by integration with loading. A method is presented to select the best process plan from a number of possible alternatives taking into account the limited availability of resources. Various aspects of the quality of a process plan are evaluated and expressed in the so-called evaluation time. To prevent redundant work, partly worked out process plans are considered as alternatives. The consequences of the different alternatives have to be estimated which includes the estimation of machining times. The loading problem is modelled as the minimization of the total evaluation time for a given order set, subjected to capacity constraints
A Process Framework for Semantics-aware Tourism Information Systems
The growing sophistication of user requirements in tourism due to the advent of new technologies such as the Semantic Web and mobile computing has imposed new possibilities for improved intelligence in Tourism Information Systems (TIS). Traditional software engineering and web engineering approaches cannot suffice, hence the need to find new product development approaches that would sufficiently enable the next generation of TIS. The next generation of TIS are expected among other things to: enable
semantics-based information processing, exhibit natural language capabilities, facilitate inter-organization exchange of information in a seamless way, and
evolve proactively in tandem with dynamic user requirements. In this paper, a product development approach called Product Line for Ontology-based Semantics-Aware Tourism Information Systems (PLOSATIS) which is a novel
hybridization of software product line engineering, and Semantic Web engineering concepts is proposed. PLOSATIS is presented as potentially effective, predictable and amenable to software process improvement initiatives
Lean construction, building information modelling and sustainability
This paper investigates the mutual relations of three current drivers of construction:
lean construction, building information modelling and sustainability. These drivers
are based on infrequently occurring changes, only incidentally simultaneous, in their
respective domains. It is contended that the drivers are mutually supportive and thus
synergistic. They are aligned in the sense that all require, promote or enable
collaboration. It is argued that these three drivers should be implemented in a unified
manner for rapid and robust improvements in construction industry performance and
the quality of the constructed facilities and their benefits for stakeholders and wider
society
Effective customer requirements management using an information supply based model
Managing customer requirements is a crucial process in any project, especially when these requirements usually keep changing throughout a project life cycle. Despite the high importance of customer requirement management in any project, there is no avail
Integrated Process Simulation and Die Design in Sheet Metal Forming
During the recent 10-15 years, Computer Aided Process Planning and Die Design
evolved as one of the most important engineering tools in sheet metal forming, particularly in
the automotive industry. This emerging role is strongly emphasized by the rapid development
of Finite Element Modelling, as well. The purpose of this paper is to give a general overview
about the recent achievements in this very important field of sheet metal forming and to
introduce some special results in this development activity. Therefore, in this paper, an
integrated process simulation and die design system developed at the University of Miskolc,
Department of Mechanical Engineering will be analysed. The proposed integrated solutions
have great practical importance to improve the global competitiveness of sheet metal forming
in the very important segment of industry. The concept described in this paper may have
specific value both for process planning and die design engineers
