Trying for improvement performance as an essential principle, since of preliminary management creation, had been noticeable and more extensive every day. Today, it has prospect behaviors beyond the formal duties that are contextual performance, extra-role behaviors, Spontaneous behaviors or organizational citizenship behaviors. The other wise, the results of studies indicate that strain hinders of this behaviors. Therefore it's necessary schematization of plans and solutions for decreasing strain and then increasing OCBs. One of the most important of the activities is recognition of the effective variables on the OCBs for its preservation, increasing and reinforcement. This study with meta-analysis approach has recognized and studied the moderator variables that have been effective on this relationship. Statistical society is the hole of the studies that have investigating the relationship between strains and OCBs, total studies are 169 with 893 effect sizes, The results of studies revealed this relationship is moderated by five moderators of the characteristics of the study sample: the kind of job and organization (governmental vs. private), organizational position (managerial vs. nonmanagerial), the kind of employee (full time or no full time), and the number of statistic society.

The purpose of this study is to explain the ability of the computer simulation methodology to improve productivity of a production system. At the beginning, it demonstrates how simulation can be employed in productivity analysis. In this regard, a case study approach was used and the proposal methodology was implemented to represent the simulation capability to enhance the productivity in the case study.
An explanation of the existing system was presented and the corresponding model called AS-IS model was designed, then the model was runned and the output was analyzed. The results of the study showed the bottlenecks and performance measures of the existing system and the initiated two models according to the simulation output, called TO-BE models.
The results obtained from the simulation experiment showed the performance measure in the TO-BE models. The manager of the company, has selected the TO-BE2 model as the best alternative based on the economical and others measure.
