Paper one “IDEF*: a comprehensive modeling methodology for the development of manufacturing enterprise systems” [1] discusses the IDEF* modeling methodology which is used to reduce the incompatibility between the models and help modeling maintenance. The paper also gives information on the structure and various components of the supporting software tool that is used. Paper two “A knowledge-base...

(e. g. the Traveling Salesperson Problem), we made the same experiments and enlarged each message to 10000 bytes by sending some additional dummy messages. Since the number of migrated messages for our algorithm is very low in comparison to randomized load balancing methods, we could achieve nearly the same results on all De Bruijn networks. For example, we achieved a speedup of 61.46 on a 64 p...

in some statistical process control applications, quality of a process or product can be characterized by a relationship between a response and one or more independent variables, which is typically referred to a profile. in this paper, polynomial profiles are considered to monitor processes in which there is a first order autoregressive relation between the error terms in each profile. a remedi...

statistical process control (spc) charts play a major role in quality control systems, and their correct interpretation leads to discovering probable irregularities and errors of the production system. in this regard, various artificial neural networks have been developed to identify mainly singular patterns of spc charts, while having drawbacks in handling multiple concurrent patterns. in this...

multivariate control charts such as hotelling`s t^ 2 and x^ 2 are commonly used for monitoring several related quality characteristics. these control charts use correlation structure that exists between quality characteristics in an attempt to improve monitoring. the purpose of this article is to discuss some issues related to the g chart proposed by levinson et al. [9] for detecting shifts in ...

when a change occurs in a process, one expects to receive a signal from a control chart as quickly as possible. upon the receipt of signal from the control chart a search for identifying the source of disturbance begins. however, searching for assignable cause around the signal time, due to the fact that the disturbance may have manifested itself into the rocess sometimes back, may not always l...
