Integrated framework to investigate value innovations

A conceptual framework has been developed to investigate value innovations within construction companies. A visual metaphor has been defined to model the innovation system where the elements of the model are objectives, strategies, environmental barriers/drivers, and organizational factors. The major idea is that none of the elements of the model alone can explain the innovative capability, and elements as well as their interrelations should be considered concurrently to investigate how the innovation system works in construction companies. An application of the framework has been demonstrated by I I cases taken from the Turkish construction industry. General findings of the research have been reported as well as specific company examples that demonstrate the major mechanisms of the innovation system. The research findings have revealed that environmental factors can have both hindering and supporting impacts on the innovation system, depending on other elements of the framework. The type of innovations is strongly related to company targets, strategies, strengths/weaknesses, and environmental factors. Moreover, matching of appropriate strategies with organizational properties leads to an increase in innovative capacity.


Capturing knowledge in construction projects: Knowledge platform for contractors
Kivrak, Serkan; Arslan, Gokhan; Dikmen Toker, İrem; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2008-04-01)
Managing knowledge effectively is critical to the survival and advance of a company, especially in project-based industries such as construction. However, capturing knowledge in construction projects is a tedious task, as knowledge is usually experience based, tacit, and hard to pass on to others. In this study, a survey was carried out among eight leading Turkish construction contractors that are operating within the international construction market. The specific objectives of this survey are to find out ...
Collaboration environments for construction: Implementation case studies
Erdogan, Bilge; Anumba, Chimay J.; Bouchlaghem, Dino; Nielsen, Yasemin (American Society of Civil Engineers (ASCE), 2008-10-01)
Although emerging technologies offer the construction industry many opportunities for computer supported collaboration environments, the companies adopting these technologies usually fail in achieving the full benefits from their implementations. The reason for this is found to be focusing too much on the technical factors and ignoring or underestimating the factors related to change, implementation, human and organizational factors, and the roles of the management and end users. Each new information techno...
Flexibility analysis: a methodology and a case study
Kahyaoglu, Y; Kayaligil, S; Buzacott, JA (Informa UK Limited, 2002-11-10)
A methodology for analysing manufacturing flexibility is proposed. A real-life case is discussed to demonstrate the proposed methodology. The case involves the grinding operations of an engine manufacturer. As an integral part of the methodology, statistical analyses using response surface methodology are carried out. Potential applications of the proposed methodology are discussed. Planning models and flexibility measure used are outlined in the appendices.
Quantiative Methodology for Determination of Cost Contingency in International Projects
Sönmez, Rifat; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2007-01-01)
This paper presents a quantitative methodology to determine financial impacts of the risk factors during the bidding stages of international construction projects. Project and country data of 26 construction projects from 21 countries were collected for evaluation of the international risk factors. The factors impacting cost contingency were identified using correlation and regression analysis techniques. The results indicated that four factors had major contributions for explaining the variations in the co...
Capacity allocation problem in flexible manufacturing systems: branch and bound based approaches
ÖZPEYNİRCİ, SELİN; Azizoğlu, Meral (Informa UK Limited, 2009-01-01)
This study considers an operation assignment and capacity allocation problem that arises in flexible manufacturing systems. The machines have limited time and tool magazine capacities and the available tools are limited. Our objective is to maximise total weight of assigned operations. We develop a branch and bound algorithm that finds the optimal solutions and a beam search algorithm that finds high quality solutions in polynomial time.
