为了提高目标跟踪精度和跟踪视频质量,研究了一种具有失真激励功能和基于机会模糊控制的视频跟踪机制及其系统架构。首先,针对目标行为空域和模糊集群,通过建立群内模糊集且依据目标移动速度构建了机会模糊控制系统。然后,在分析跟踪目标的差异性和目标移动速度的随机性的基础上,以激励模糊集群用户的机会逻辑控制为目标,提出了基于失真激励的视频跟踪机制及其系统架构。最后,实验结果表明,提出的算法在系统执行效率、视频传输时延和跟踪视频质量等方面具有明显优势。 相似文献

The aim of this paper is to examine how wine firms implement their marketing strategies based on the recognition of market opportunities by their Chief Executive Officers (CEOs). Firstly, we describe the marketing activities in 69 traditional Chilean wine firms. Then, in-depth interviews with CEOs of two wineries are analysed using cognitive maps to uncover the cognitive processes responsible for recognizing and executing market activities. Our findings indicate that there is a similar set of strategic resources across the wineries, but the CEOs’ different perceptions of the usefulness of these resources in the implementation of marketing strategies have led them to select diverse strategies to increasing both the price per bottle and wine sales. This paper makes two contributions. Firstly, we compare the benefit of implementing traditional and relational marketing strategies in the Chilean wine industry. Secondly, we show that the CEOs’ perception of feedback processes among the available resources affects the recognition of market opportunities and the marketing strategy in wine firms. 相似文献

Shared risks and opportunities set specific premises for risk management (RM) in temporary multi-organizations (TMOs). However, most project RM research is presented from the perspective of a single-organizational project delivery team or covers limited risk perceptions and RM approaches. This paper aims to address how well the body of knowledge on multi-organizational RM corresponds to a state-of-art understanding on project RM and to identify which gaps need to be addressed in future research. The review involves: 1) the preferred view of risk as threat and/or opportunity, 2) the nature of addressed risks as anticipated or unanticipated risks or unrealistic assumptions, 3) the role of the multi-organization as the source of risks and/or resources for risk management (RM), and 4) the allocation of risk responsibilities. The review covers research papers published between 2000 and 2012 in four journals: International Journal of Project Management (IJPM), Project Management Journal (PMJ), Journal of Construction Engineering and Management (JCEM), and IEEE Transactions on Software Engineering (TSE). 105 eligible research papers were identified. The results and conclusion outline the identified main gaps in multi-organizational RM research compared to the state-of-art RM research and TMO-specific characteristics. The results can be used to inform research agendas on more holistic and dynamic multi-organizational RM concepts. 相似文献

The UK's NJCC Code of Procedure for Single Stage Selective Tendering (now withdrawn) and its successor, the CIB's Code of Practice for the Selection of Main Contractors are criticized in the light of decisions of the common law courts with regard to regulation of the tendering process. It is argued that a new ‘Tendering Code’ should be produced in the style and format of a contract document which reflects not only the statutory regulation imposed on public bodies, but common law decisions of the courts. The nature of this tendering contract is explained as a means of regulating the tendering process. Issues discussed are: dealing with errors and irregularities found in tenders; dealing with non-compliant tenders; dealing with tender withdrawal prior to its acceptance or rejection; making provisions as to time for submission of tenders and dealing with late tenders; making provision for submission of tender by fax or other electronic means; making provision for evaluation of tenders received; and imposing or negotiating reductions in price with tenderers prior to acceptance. The paper concludes that the common law obligations placed on the owner to treat all tenderers equally and fairly and to apply the tender conditions when evaluating tenders and awarding contracts seems to be good common sense and of commercial advantage, not only to the immediate parties concerned but also to the wider community. 相似文献
