Technology Strategy for Re-engineering Design and Construction

Automation technology can provide construction firms with a number of competitive advantages. Technology strategy guides a firm's approach to all technology, including automation. Engineering management educators, researchers, and construction industry professionals need improved understanding of how technology affects results, and how to better target investments to improve competitive performance. A more formal approach to the concept of technology strategy can benefit the construction manager in his efforts to remain competitive in increasingly hostile markets. This paper recommends consideration of five specific dimensions of technology strategy within the overall parameters of market conditions, firm capabilities and goals, and stage of technology evolution. Examples of the application of this framework in the formulation of technology strategy are provided for CAD applications, co-ordinated positioning technology and advanced falsework and formwork mechanisation to support construction field operations. Results from this continuing line of research can assist managers in making complex and difficult decisions regarding reengineering construction processes in using new construction technology and benefit future researchers by providing new tools for analysis. Through managing technology to best suit the existing capabilities of their firm, and addressing the market forces, engineering managers can better face the increasingly competitive environment in which they operate

Global communication part 1: the use of apparel CAD technology

Trends needed for improved communication systems, through the development of future computer-aided design technology (CAD) applications, is a theme that has received attention due to its perceived benefits in improving global supply chain efficiencies. This article discusses the developments of both 2D and 3D computer-aided design capabilities, found within global fashion supply chain relationships and environments. Major characteristics identified within the data suggest that CAD/CAM technology appears to be improving; however, evidence also suggest a plateau effect, which is accrediting forced profits towards information technology manufactures, and arguably compromising the industry's competitive advantage. Nevertheless, 2D CAD increases communication speed; whereas 3D human interaction technology is seen to be evolving slowly and questionably with limited success. The article discusses the findings and also presents the issues regarding human interaction; technology education; and individual communication enhancements using technology processes. These are still prevalent topics for the future developments of global strategy and cultural communication amalgamation

Environmental proactivity and firms' performance: Mediation effect of competitive advantages in Spanish wineries

The main aim of this paper is to show the extent to which environmental proactivity is able to generate competitive advantages in a firm in order to improve their economic-financial performance by introducing the role of managerial perception into the analysis. This study focuses on Spanish wineries and their environmental practices and covers a total of 4598 wineries with a sample of 142 valid responses during the month of November 2015. The results can be summarized as follows. Firstly, there is positive environmental proactivity in terms of obtaining both cost-based and differentiation-based competitive advantages. Likewise, this proactivity has a positive impact on the manager’s perception of performance. Secondly, obtaining differentiation-based competitive advantages has a positive impact on the manager’s perception of performance although a negative impact on performance itself. There is, however, no significant evidence of the impact of cost-based competitive advantages on financial performance nor on the perception of performance itself, nor the impact of environmental proactivity on financial performance

Real time integration of user preferences into virtual prototypes

Within new product development (NPD), both virtual prototypes and physical prototypes play important roles in creating, testing and modifying designs. However, in the current design process, these two forms of prototyping methods are normally used independently and converted from one to the other during different design phases. This conversion process is time consuming and expensive and also introduces potential information loss/corruption problems. If the design process requires many iterations, it may simply be impractical to generate all the conversions that are theoretically required. Therefore, the integration of virtual and physical prototyping may offer a possible solution where the design definition is maintained simultaneously in both the virtual and physical environment. The overall aim of this research was to develop an interface or a tool that achieves real time integration of physical and virtual prototyping. “Real time integration” here means changes to the virtual prototypes will reflect any changes that have been made contemporaneously to the physical prototypes, and vice versa. Thus, conversion of the prototype from physical to virtual (or vice versa) will be achieved immediately, hence saving time and cost. A review of the literature was undertaken to determine what previous research has been conducted in this area. The result of the review shows the research in this area is still in its infancy. The research hypothesis was developed through the use of a questionnaire survey. Totally 102 questionnaires were sent to designers, design directors or design managers to address the issue: will industrial designers want to make use of real time integration and if so, how? The outcome from the literature review drove further development of the research hypothesis and an initial pilot experiment to test this. The pilot trial was designed to address the research questions: • Can real time physical and virtual prototyping integration be conveniently demonstrated? • Will designers and users be comfortable using the integration method? • Will users recognise the benefits of the integration? The results showed that real time integration between physical and virtual prototyping is necessary in helping designers develop new products and for getting users more closely involved. The future research suggested is that more investigations and experiments are needed to explore a proper method that simultaneously employing these two types of prototyping in product development process.

Global communication part 2: the use of apparel product data management technology

Improving IT communication systems, through the evolution of future PDM applications, is a theme that has received attention due to its perceived benefits in developing global supply chain success factors. This paper discusses the developments and capabilities of such systems, found within global fashion supply chain relationships and environments. Major characteristics identified within the data suggest that PDM technology appears to be improving the speed of data transfer; however, evidence also suggest that the technologies are evolving quicker than consumer understanding, and arguably cost more to implement, train staff and maintain. Nevertheless, PDM technology increases communication efficiency and helps to enhance social economic and corporate development. The article discusses the findings and also presents the issues regarding human interaction; iconography, infrastructure necessity and individual communication enhancements using a variety of technology processes. PDM technology adoption is still a prevalent topic for the long-term developments of global strategy and communication amalgamation

The Role of Technology Support Centres in stimulating Entrepreneurship and Innovation in SME Clusters

The Innovative Product Development Centre (IPDC) was established at the University of Wolverhampton in the West Midlands region of the UK with a mission “to help small and medium sized companies improve their business, secure jobs and contribute to the economic regeneration of the West Midlands Region”. Since 2000, the IPDC has helped several hundred enterprises to develop their businesses through innovation and new product development. Demand for help is high, which reflects a healthy desire by the SMEs to innovate. The assistance given is time limited, but its impact on the business is extremely varied. This paper will discuss the role that a university based product development and technology centre can play in supporting a regional agenda for developing entrepreneurship and innovation in SMEs. Using case studies drawn from the experiences of working with SMEs from the West Midlands region, the paper will consider key issues such as: • Entrepreneurial leadership in SMEs • Formalised approaches for managing NPD • Technology support for innovation • Product innovation • Business networks and entrepreneurial clusters The paper will conclude that university based centres like IPDC can play a vital role in regional development programmes by helping minimise the risks for entrepreneurs to develop new products or adopt new process technologies. Importantly, investments in such centres by regional development agencies can be pivotal for stimulating access to new technology for the exploitation of entrepreneurial clusters and creating attractive inward investment opportunities

Providing value to a business using a lightweight design system to support knowledge reuse by designers

This paper describes an alternative approach to knowledge based systems in engineering than traditional geometry or explicit knowledge focused systems. Past systems have supported product optimisation rather than creative solutions and provide little benefit to businesses for bespoke and low volume products or products which do not benefit from optimisation. The approach here addresses this by supporting the creativity of designers through codified tacit knowledge and encouraging knowledge reuse for bespoke product development, in particular for small to medium sized enterprises. The implementation and evaluation of the approach is described within a company producing bespoke fixtures and tooling in shorter than average lead times. The active support of knowledge management in the company is intended to add value to the business by further reducing the lead times of the designs and creating a positive impact to business processes. The evaluation demonstrates a viable alternative framework to the traditional management of knowledge in engineering, which could be implemented by other small to medium enterprises

Aerated blast furnace slag filters for enhanced nitrogen and phosphorus removal from small wastewater treatment plants

Rock filters (RF) are a promising alternative technology for natural wastewater treatment for upgrading WSP effluent. However, the application of RF in the removal of eutrophic nutrients, nitrogen and phosphorus, is very limited. Accordingly, the overall objective of this study was to develop a lowcost RF system for the purpose of enhanced nutrient removal from WSP effluents, which would be able to produce effluents which comply with the requirements of the EU Urban Waste Water Treatment Directive (UWWTD) (911271lEEC) and suitable for small communities. Therefore, a combination system comprising a primary facultative pond and an aerated rock filter (ARF) system-either vertically or horizontally loaded-was investigated at the University of Leeds' experimental station at Esholt Wastewater Treatment Works, Bradford, UK. Blast furnace slag (BFS) and limestone were selected for use in the ARF system owing to their high potential for P removal and their low cost. This study involved three major qperiments: (1) a comparison of aerated vertical-flow and horizontal-flow limestone filters for nitrogen removal; (2) a comparison of aerated limestone + blast furnace slag (BFS) filter and aerated BFS filters for nitrogen and phosphorus removal; and (3) a comparison of vertical-flow and horizontal-flow BFS filters for nitrogen and phosphorus removal. The vertical upward-flow ARF system was found to be superior to the horizontal-flow ARF system in terms of nitrogen removal, mostly thiough bacterial nitrification processes in both the aerated limestone and BFS filter studies. The BFS filter medium (whieh is low-cost) showed a much higher potential in removing phosphortls from pond effluent than the limestone medium. As a result, the combination of a vertical upward-flow ARF system and an economical and effective P-removal filter medium, such as BFS, was found to be an ideal optionfor the total nutrient removal of both nitrogen and phosphorus from wastewater. In parallel with these experiments, studies on the aerated BFS filter effective life and major in-filter phosphorus removal pathways were carried out. From the standard batch experiments of Pmax adsorption capacity of BFS, as well as six-month data collection of daily average P-removal, it was found that the effective life of the aerated BFS filter was 6.5 years. Scanning electron microscopy and X-ray diffraction spectrometric analyses on the surface of BFS, particulates and sediment samples revealed that the apparent mechanisms of P-removal in the filter are adsorption on the amorphous oxide phase of the BFS surface and precipitation within the filter
