A data model for regions with indeterminate boundaries

Most of spatial phenomena like natural vegetation units and land use areas constantly change over time and have uncertainty spatial extents. Till now, a considerable number of data models have been proposed for spatial objects with sharp boundaries as well as with indeterminate boundaries. However, they mainly concern space and time or space and fuzziness and not yet integrate them into a single unified framework. This paper introduces a formal definition of the conceptual fuzzy spatiotemporal data model, called FSTDM for fuzzy regions based on fuzzy set theory. We also contribute a method of manipulating queries with the presence of both temporal predicate and fuzzy spatial predicate in the condition clause efficiently. We then implement a prototype system.Through the experimental results, we prove that our work can be used to build a specialized system such as GIS, spatial database, and so on.     

GRAMMATICAL COMPLEXITY OF FEIGENBAUM TYPE ATTRACTORS IN PERIODIC WINDOWS

In [7,8] the grammatical complexity of the Feigenbaurn attractor and the general Feigenbaurn attractors, generated by period - n - tupling, are studied. In this paper we study the grammatical complexity of the Feigenbaurn type attractors, including Feigenbaurn attractors and general Feigenbaurn attractors,in periodic windows. It is shown that the languages determined by these attractors are CLS and are. not CFL.

利用系统动力学的原理和建模方法描述了企业生产能力与企业物流、信息流与资金流所涉及的各种计划、生产、采购、仓储、销售及财务等职能的关系，利用因果环路图研究分析了生产能力与库存水平、交货期、市场份额、产品价格、成本、利润率、人力等多种因素的因果反馈关系，并构建了生产能力扩大的系统动力学模型来刻画其变化的复杂性与动态性，在两种市场需求（阶跃需求和泊松流随机需求）下模型的仿真结果表明，该模型能较好的反应生产能力扩大的动态行为。     

FROM MANUFACTURING SCHEDULING TO SUPPLY CHAIN COORDINATION：THE CONTROL OF COMPLEXITY AND UNCERTAINTY

With time-based competition and rapid technology advancements, effective manufacturingscheduling and supply chain coordination are critical to quickly respond to changing marketconditions. These problems, however, are difficult in view of inherent complexity and variousuncertainties involved. Based on a series of results by the authors, decomposition and coordination byusing Lagrangian relaxation is identified in this paper as an effective way to control complexity anduncertainty.A manufacturing scheduling problem is first formulated within the job shop context withuncertain order arrivals, processing times, due dates, and part priorities as a separable optimizationproblem. A solution methodology that combines Lagrangian relaxation, stochastic dynamicprogramming, and heuristics is developed. Method improvements to effectively solve large problemsare also highlighted. To extend manufacturing scheduling within a factory to coordinate autonomicmembers across chains of suppliers, a decentralized supply chai
