Oversea hydrocarbon exploration always faces some problems, such as multiple basin types, different exploration prospects, various exploration degrees, diverse data quantities and geological recognitions. This paper focuses on overseas basins with different exploration degrees and offers a new evaluation system and research method for fast evaluation and risk analysis on hydrocarbon potential. Based on the theory of probability, this new evaluation system evaluates each parameter and core accumulation factor with comprehensive and quantitative assignment, to accelerate geological evaluation. In addition, this paper suggests that source rock evaluation should be the core criterion in screening evaluation of poor-explored basins, and also proposes that both the exploration potential and geological recognition should drive the evaluation for basins with high exploration degrees. This new system and method, which is an effective system for fast basin evaluation, is suggested to be used in oversea evaluation and decision-making objectively, scientifically and efficiently. 相似文献

Personalised information systems (PISs), related to different fields (travelling and mobility, production, logistics and so on), represent an object of many research and development perspectives. Using PISs, it becomes possible to supply the user only with the pertinent information that suits their preferences. Indeed, thanks to personalisation, the user may feel that a particular PIS is developed for them. This system adaptation becomes a necessity for the user's satisfaction. In this context, many studies were orientated toward the user modelling, the design methods of PIS and the personalisation algorithms, etc. but, the evaluation of these systems is neglected. Difficulties concerning context-centred evaluation appear. This paper is focused on the evaluation of the personalised information systems in order to optimise the personalisation quality according to several criteria. For such systems, it is important to envisage new adapted evaluation methods. An evaluation method using a PIS simulation model, called MetSim (Method evaluation per Simulation), is proposed. MetSim is also based on the case-based reasoning system to identify problems. This evaluation approach has been validated by applying it to assess PISs in the logistics field. 相似文献

It is essential to devise a representation scheme for the metal stamping part design which allows the designer to capture and reason the design information, and ultimately, to take various considerations into account and make evaluation decisions. In our research, the feature-based approach is used to represent the metal stamping part, and feature-based metal stamping part and process design has been studied and presented in a two-part paper. This is the first of a two-part paper focusing on stampability evaluation. In Part II a feature-based stamping process planning approach is investigated. This paper presents a feature- and knowledge-based stampability evaluation system. Tasks of this research include identification of the aims, criteria, and procedure of stampability evaluation, as well as the formalization of the stampability evaluation knowledge. Stampability evaluation is classified into stampability verification and stampability measurement. Stampability verification is used to determine whether a part design is stampable or not. Stampability measurement can be employed to select a best design from stampable candidate designs. Based on the stamping design feature definition, a stampability-coding scheme with incorporated knowledge has been developed to enable comprehensive stampability evaluation. Finally, a case study demonstrates the feasibility of such stampability evaluation system. 相似文献

为了更加有效地对机械运动方案实施定量评价,利用神经网络具有的非线性映射特征,提出了一种神经网络评价方法,建立了一种多层次多目标的方案评价模型。该方法将神经网络与模糊数学相结合,首先利用方案评价样本对根据评价指标体系构建的神经网络进行训练,使得评价模型可以较好地反映评价属性值和评价结论间的关系以及各评价指标的权重,然后,将备选方案的各项指标值模糊量化,输入该模型,即可获得评价结果,从而可有效地利用专家经验代替评价群体对运动方案进行评价,简化了评价过程。讨论了基于神经网络运动方案评价的一些关键问题,并通过一个实例验证该模型是合理可行的,从而为解决运动方案评价提供了一种新的思路。 相似文献
