Complex Event Processing (CEP) is a promising technology that deals with event stream in a cenralized manner. But in some application scenario such as the express delivery business, business-related data is scattered in the network and must be obtained by request. For the purpose of resolving the difficulty to utilize and process such distributed infomation, the paper comprehensively utilizes v...

this paper analyses efficiency of short horizon event study methodology in general and efficiency of various test statistics based on price and trading volume in the period (iranian calendar) 1380:1389-q1 (2240 days) applying simulation method. we evaluate efficiency of 8 test statistics including parametric, non-parametric and induced variance statistics. we find various test statistics have e...

 This study deals with line balancing of BOB T-shirt model with the help of control limit analysis and discrete event simulation of the assembly lines. In this study control limit analysis is used to measure the performance of the assembly line and used to show the bottleneck operations of the assembly line and line balancing technique improves the productivity of the sewing line of the model. ...
