    Development of an integrated logistical support system for all types of national security services requires the solution to a problem of definition its rational structure. The methodical approach proposes to consider this issue as a complex of two successive optimization tasks. In the first place, it assumes to determine regional logistics clusters amount and then to optimize their logistics infrastructure. The models and methods are developed to allow optimization of the integrated logistical support system structure according to a real transport network communications and a regional supply chain by a minimal total logistics costs criterion

An executive summary, the integrated logistics support strategy, preparation of planning documents and a supportability analysis of the 1.8 meter centrifuge are discussed

    A development of logistics management models for the Space Transportation System

    Get PDF
    A new analytic queueing approach was described which relates stockage levels, repair level decisions, and the project network schedule of prelaunch operations directly to the probability distribution of the space transportation system launch delay. Finite source population and limited repair capability were additional factors included in this logistics management model developed specifically for STS maintenance requirements. Data presently available to support logistics decisions were based on a comparability study of heavy aircraft components. A two-phase program is recommended by which NASA would implement an integrated data collection system, assemble logistics data from previous STS flights, revise extant logistics planning and resource requirement parameters using Bayes-Lin techniques, and adjust for uncertainty surrounding logistics systems performance parameters. The implementation of these recommendations can be expected to deliver more cost-effective logistics support

    Wireless communication, identification and sensing technologies enabling integrated logistics: a study in the harbor environment

    Get PDF
    In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future

    Marketing and logistic support of Ukrainian regional markets for innovative products distribution

    Get PDF
    The integrated assessment of marketing support and level of logistics potential of Ukrainian regional markets according to the proposed structure is carried out. The study was carried out by determining the essence of marketing resources and logistics potential of regions that, as a result, reflects their focus on the formation of an effective policy of distribution of innovative products of industrial enterprises. A matrix that reflects the grouping of Ukrainian regions in zones with balanced and unbalanced levels of appraisal indicators is provided

    'Sense and respond' and 'autonomic' logistics: a review of US and UK developments

    Get PDF
    Until recently, platform-based, logistics applications required data to be physically downloaded and transferred between systems so that analysis could estimate the status of key components. In both the Sense and Respond Logistics (S&RL) and Autonomic Logistics (AL) systems, prognostics have been added to monitoring functions, effectively extending the reach of Combat Service Support (CSS). The scope the supply chain has also been expanded with the potential inclusion of some classes of supply within the AL approach. The real time and predictive aspects are relatively new logistics developments facilitated by the real-time communication of data while platforms are in operation. While the (Australian) Military Integrated Logistics Information System (MILIS) proposes to extend the reach of supply chain information to sub-unit level, it falls short of crossing the gap to link Health and Usage Monitoring System (HUMS), platform-based, data into the logistics continuum to provide end-to-end visibility, a foxhole-to-factory-to-foxhole perspective, of the supply chain. This paper will review developments in recent military applications of Autonomic Logistics and Sense & Respond Logistics in the United States Defense Forces and the military in the UK while also considering a selection of Australian Defence Force programs. It will state the case for application of Autonomic Logistics and Sense & Respond Logistics to the ASLAV and Bushmaster platforms, in a similar fashion to those employed in the US and the UK, as a source of accurate and up-to-date CSS information for the various levels of command

    Design of Closed Loop Supply Chains

    Increased concern for the environment has lead to new techniques to design products and supply chains that are both economically and ecologically feasible. This paper deals with the product - and corresponding supply chain design for a refrigerator. Literature study shows that there are many models to support product design and logistics separately, but not in an integrated way. In our research we develop quantitative modelling to support an optimal design structure of a product, i.e. modularity, repairability, recyclability, as well as the optimal locations and goods flows allocation in the logistics system. Environmental impacts are measured by energy and waste. Economic costs are modelled as linear functions of volumes with a fixed set-up component for facilities. We apply this model using real life R&D data of a Japanese consumer electronics company. The model is run for different scenarios using different parameter settings such as centralised versus decentralised logistics, alternative product designs, varying return quality and quantity, and potential environmental legislation based on producer responsibility.supply chain management;reverse logistics;facility location;network design;product design

    Analysis of Logistics in Support of a Human Lunar Outpost

    Get PDF
    Strategic level analysis of the integrated behavior of lunar transportation system and lunar surface system architecture options is performed to inform NASA Constellation Program senior management on the benefit, viability, affordability, and robustness of system design choices. This paper presents an overview of the approach used to perform the campaign (strategic) analysis, with an emphasis on the logistics modeling and the impacts of logistics resupply on campaign behavior. An overview of deterministic and probabilistic analysis approaches is provided, with a discussion of the importance of each approach to understanding the integrated system behavior. The logistics required to support lunar surface habitation are analyzed from both 'macro-logistics' and 'micro-logistics' perspectives, where macro-logistics focuses on the delivery of goods to a destination and micro-logistics focuses on local handling of re-supply goods at a destination. An example campaign is provided to tie the theories of campaign analysis to results generation capabilities
