航天装备研制涉及论证、研制、生产、试验、综合保障等各个环节,所产生的数据具有种类多、数据量大、异构性强等特点,且数据资源分散于各科研机构院所,形成一个个数据孤岛,严重制约了型号数据的统一管理和协同应用。为了建立“逻辑统一、物理分散”的航天装备统一大数据中心,本文提出一种航天装备大数据资源平台构建技术,该平台基于统一的数据编目规范,综合利用云计算、微服务、区块链等技术,可实现多维异构数据深度融合管控,实现基于型号科研生产活动下的数据逻辑统一管理和实体分布式存储,能够解决航天装备整个研制活动全要素全过程的数据采集和可控共享的现实需求,为各业务场景下的数据分析奠定基础。 相似文献

Industrial supply chains have emerged as the focus of much economic and business research over the previous decade and defence is no exception. This paper reviews contributions made to the body of knowledge in this field with particular attention given to primary research undertaken on the UK defence industrial supply system. In doing so, the author assesses the quantity and quality of knowledge available to researchers, analysts and policy makers. There have been a number of valuable contributions to the literature and this paper reveals a subject that is extremely complicated, dynamic and yet under‐researched. It is suggested that it may well be this complexity and dynamism, coupled with difficulty in accessing data, that has inhibited research development in this field. Defence industry supply systems are repeatedly referred to as ‘chains’; however, primary research consistently suggests this is a misnomer – the author concludes that future analysis of the UK defence sector must embrace directly the economics of networks if understanding of the same is to progress and industrial ‘invisibility’ is to be avoided. 相似文献

This article proposes two dual‐ascent algorithms and uses each in combination with a primal drop heuristic embedded within a branch and bound framework to solve the uncapacitated production assembly distribution system (i.e., supply chain) design problem, which is formulated as a mixed integer program. Computational results indicate that one approach, which combines primal drop and dual‐ascent heuristics, can solve instances within reasonable time and prescribes solutions with gaps between the primal and dual solution values that are less than 0.15%, an efficacy suiting it for actual large‐scale applications. © 2012 Wiley Periodicals, Inc.

An important aspect of supply chain management is dealing with demand and supply uncertainty. The uncertainty of future supply can be reduced if a company is able to obtain advance capacity information (ACI) about future supply/production capacity availability from its supplier. We address a periodic‐review inventory system under stochastic demand and stochastic limited supply, for which ACI is available. We show that the optimal ordering policy is a state‐dependent base‐stock policy characterized by a base‐stock level that is a function of ACI. We establish a link with inventory models that use advance demand information (ADI) by developing a capacitated inventory system with ADI, and we show that equivalence can only be set under a very specific and restrictive assumption, implying that ADI insights will not necessarily hold in the ACI environment. Our numerical results reveal several managerial insights. In particular, we show that ACI is most beneficial when there is sufficient flexibility to react to anticipated demand and supply capacity mismatches. Further, most of the benefits can be achieved with only limited future visibility. We also show that the system parameters affecting the value of ACI interact in a complex way and therefore need to be considered in an integrated manner. © 2011 Wiley Periodicals, Inc.
