  • Impact of logistics performance on world economic growth (2007–2012)

    This research proposes a global aggregate production function in dynamic terms which captures the contribution of logistics performance to world economic growth. The well–known model of Mankiw et al. (1992) is used, incorporating the logistics performance index as an explicative production factor, with good results. The production function is estimated empirically for the world's countries with ...

  • Built to last: population aging and long run development in metropolitan Europe

    The paper examines the role of demography on the growth perspectives of European metropolitan areas. Our findings are in support of the key role played by the demographic structure of the population in determining the economic prospects of European cities. Regions and cities with higher levels of dependency ratios are found to show lower growth rates, in the long run. This evidence supports ...

  • Technological progress, structural change and productivity growth in the manufacturing sector of South Korea

    This paper focuses on the impact of technology and structural change on the aggregate productivity growth in the manufacturing sector of South Korea, using the eight firm size classes over the period 1970–2000. The conventional shift-share analysis is used to measure the impact of shift of both labour and capital inputs. The results show that structural change on an average was conducive to ...

  • In-house R&D, technology purchase and innovation: empirical evidences from Chinese hi-tech industries, 1995–2004

    We empirically estimated the effect of three types of investment in acquiring technological knowledge (in-house R&D, importing foreign technology and purchasing domestic technology) on the innovation output of Chinese firms in four hi-tech industries. These investments on technology are assumed to generate different types of knowledge, which in turn contribute to the enhancement of the ...

  • Mixed–Integer Linear Programming formulation for block–cave sequence optimisation

    Relying only on manual planning methods or computer software based on heuristic algorithms will lead to mine schedules that are not the optimal global solution. The objective of this paper is to develop a practical optimisation framework to schedule production for caving operations. We present two Mixed–Integer Linear Programming (MILP) formulations for the long–term production scheduling of ...

  • Large-scale open pit production scheduling using Mixed Integer Linear Programming

    One of the main obstacles in using Mixed Integer Linear Programming (MILP) formulations for open pit production scheduling is the size of the problem. The main objective of this paper is to present and implement a practical MILP formulation for open pit production scheduling problem. To reduce the number of binary integer variables in the formulation, we aggregate blocks into larger units ...

  • A multi–step approach to long–term open–pit production planning

    The objective of this paper is to develop, verify, and present a multi–step methodology for three interrelated key components of open–pit mine planning: controlled optimal phase–design, characterisation of selective mining–units, and long–term production scheduling optimisation. A hybrid solution methodology for open–pit phase–design using integer programming and a local search heuristic is ...

  • Converting the dreaded PCBs into useful commodities

    For decades polychlorinated biphenyls (PCBs) have been high on the list of toxins the public fears. A new vitrification technology is claimed to be able to completely destroy PCBs and other toxins in contaminated sediment by meltingit into a glass aggregate product that can be used in the construction industry. This process, developed by Minergy Corp., costs about as much as landfilling, without ...

  • JPE Investment provides evidence of a solution to UK aggregates shortages

    An upgrade to the processing capability at Elford quarry to include a modular washing plant from CDE Global has resulted in a significant increase in the value of the products being produced. The level of demand for the recycled sand and aggregate products suggests that C&D recycling plants offer a real solution to a diminishing supply of virgin material in the UK. JPE Aggregates has operated ...

  • By-product to commercial output

    More than 200,000 tonnes of material have passed through the CDE washing plant at Irish Asphalt’s Duleek Quarry, in Co. Meath, since its installation in the summer of 2003. In July 2004 the plant’s ownership will transfer to Irish Asphalt, part of the Lagan Holdings Group, having been operated on a price-pertonne basis by CDE since its installation. The Euro 1.5 million contract ...

  • Overcoming the natural resource constraints through dedicated R&D efforts: contrasting the non-renewable and the renewable resource economies

    There exist specific factor scarcities if, and only if, the inputs of the production process are not perfect substitutes. Under the extreme assumption of strict factor complementarity between labour and resources in the production of some aggregate consumption good, and assuming that the technical coefficient of the resource input can be improved through a dedicated research effort, we compare ...
