A primary function of production management is the control of inventories. The typical manner of economic inventory control calls for a 'pre-stocking' approach in which the focus is on the reorder quantities which should be put into inventory. A second manner of controlling inventories is what can be called a 'post-stocking' analysis. Here the focus is on how much of the present inventory already in stock should be declared as ...
A method is given for the synthesis of multiple-valued symmetric function. In an earlier paper a canonical form was derived for the expression of each decisive multiple-valued fundamental symmetric function as a product of certain input terms based on the simple symmetric functions. An algorithm is given for the derivation of maximal product terms which may be used in a representation for a decisive symmetric function. The algorithm is extended ...
This report evaluates the role of the pluribus, a multiprocessor/multibus system, in its role as the communications control processor (CCP) at the Seismic Data Analysis Center (SDAC) over the 26 months from its installation in April 1977 through May 1979. In capacity the six processor Pluribus at the SDAC provides a bandwidth somewhat greater than 750,000 instructions per second, equivalent to three processors working full time. For the 16.8 KB/sec ...
This report presents the computational requirements for a new detection processor and regional analysis system at the Seismic Data Analysis Center (SDAC). In addition, the report considers the computational requirements to support a research environment at the SDAC which would include the detection/regional analysis capability as well as seismic research, development of new signal processing algorithms and techniques, and seismic experiments and applications of data base management techniques. Based on ...
a new machine tool now in the final stagesof development at the pacific northwest laboratory uses a unique tool motion to produce diamond-turned surfaces of exceptionally high quality. the cutting tool is computer programmed to move in 4-nm increments along two axes: an x axis and an omega axis. exceptionally stiff and accurate control of the tool is possible with this 'omega-x' system. copper surfaces of revolution have been produced ...
