The main objective of this paper is to give an example of how expert systems techniques for distributed decision-making can be combined with contemporary numerical optimization techniques for the purposes of supply chain optimization and to describe the resulting software implementation. In this paper, multi-agent modelling techniques are applied to simulate and control a simple demand-driven supply chain network system, with the manufacturing component being optimized through mathematical programming. The system measures supply chain performance and the effect of different parameters in the replenishment control system, and can be used to simulate the behaviour of a system that uses optimization for part of its decision-making. The objective of this supply chain network system is to reduce operating cost, while maintaining a high level of customer order fulfilment. 相似文献

Recently, quality of life has become a commonly used concept and is showing growing significance in economic and political terms. Additionally, quality of life issues have been recognized within the migration processes. In one view, quality of life relates to the degree to which the necessary conditions for satisfaction exists in a given society or region.It is argued that quality, as a measurable variable would refer to both the subject and the object of inquiry. In this sense, quality of life has two aspects, psychological and environmental ones. Nevertheless, this limitation constitutes a major problem since some researchers have totally neglected the perception of the people who live there, while another limitation is about the components, indices and indicators chosen in a certain analysis.In this paper, the aim is to test some measurement methods of the quality of life and to show the possibilities and limitations of a developing area in comparison to developed ones. In this way, some comparative analysis can be performed on the measurement methods of the quality of life levels with respect to regional variations. 相似文献

The paper explores the multiple ways in which visits affect the understanding of home for the Turkish–German second generation who have relocated to Turkey. Based on thematic–narrative analysis of 116 life-story interviews with second-generation ‘returnees’ in five regions of Turkey, three types of visits are identified: (i) family visits to Turkey whilst growing up in Germany; (ii) visits to Germany after the second generation has ‘returned’ to Turkey; (iii) visits to Turkey by the second generation's Germany-residing relatives and friends. Each type has different meanings for the visitors and the visited, creating fluid reflections on the meaning of home, which, especially for the second-generation ‘returnees’, tends to become fractured. Constantly comparing their two home(-land)s since childhood, they often simultaneously feel both ‘here’ and ‘there’ as a result of changing attachments and a mix of positive and negative experiences in both locales with their families, friends and the dominant others. 相似文献
