The aim of this paper is to discuss the approximate rea- soning problems with interval-valued fuzzy environments based on the fully implicational idea. First, this paper constructs a class of interval-valued fuzzy implications by means of a type of impli- cations and a parameter on the unit interval, then uses them to establish fully implicational reasoning methods for interval-valued fuzzy modus ponens (IFMP) and interval-valued fuzzy modus tel- lens (IFMT) problems. At the same time the reversibility properties of these methods are analyzed and the reversible conditions are given. It is shown that the existing unified forms of α-triple I (the abbreviation of triple implications) methods for FMP and FMT can be seen as the particular cases of our methods for IFMP and IFMT. 展开更多

Hydrothermal activity from a hydrothermal circulatory system is a special geological event, it is of importance to the formation of some massive sulfide deposits (hydrothermal deposits). The Authors think that Jiama polymetallic ore deposit in Gangdise tectonic zone, Tibet is a special skarn deposit i.e. a “hydrothermal\|metasomatic skarn deposit" bound up with benthonic hydrothermal circulatory system. Its important characteristics are as follows: 1 Evolution of the Gangdise island arc in studied area may be divided into three stages Middle Jurassic volcanic arc stage; Middle—Late Jurassic and Early Cretaceous inter arc sedimentary basin stage; and Eogene magmatic arc stage. The deposit is confined to the inter arc sedimentary basin. Existing data indicate that the volcanic arc provided Jiama deposit with abundant ore\|forming material; the inter arc sedimentary basin provided Jiama deposit with absolutely necessary space; the magmatic arc created reconcentration condition for the Jiama deposit. 展开更多

The reduction of wasteful variation within the supp ly chain is naturally suited to high and stable volumes, as epitomised in the lean practices of the automotive industry. However, with the growth of innovative pr oducts, typically characterised by lower volumes and uncertain demand, it is als o important to develop strategies to effectively manage the externally imposed v ariation resulting from volatile market demand. Such strategies often come under the banner of quick response or agile supply. System variation is the common denominator, for whereas lean strategies emphasis e the need for stability and the reduction of wasteful supply chain variation, a gile emphasises the need to respond to externally imposed demand variation. Simi larly, lean supply is closely associated with level scheduling and investing in inventory to decouple demand variation from the supply chain, whereas, agile sup ply is associated with investing in responsive capacity as inventory requirement s cannot be effectively predicted. This distinction between lean and agile supply, highlights a trade-off between investing in responsive capacity and decoupling inventory, which is closely related to the conflicting manufacturing tasks of fast response and low cost. The implications of this conflict have been more widely felt in recent years, as companies have opted to outsource manufacture to low cost overseas suppliers. T he rationale is to reduce manufacturing costs, but the trade-off is a dramatic loss of responsive capacity with higher dependency on decoupling inventory. As with lean and agile supply, the trade-off implications of such choices need to be acknowledged, conceptually understood and then separate out or otherwise r esolved. This paper introduces the business need before exploring the significance of var iation and the concept of managing variation in a delivery system using responsi ve capacity and decoupling inventory. These concepts will then be used to unpack the lean and agile paradigms before applying the thinking to a more detailed in dustrial case concerning offshore supply decisions. The paper concludes with som e reflections. 展开更多
