Combined with the deformation between the slider and slide of linear rolling guide (LRG), the analytical model of static stiffness can be put forward. By the ANSYS, the deformation can be gained, which come from the slider and slide under external load and preloading. At the same time, the normal and tangential stiffness of joint surface can be obtained. By setting up spring-damping dynamic model of LRG, the first 5-order theoretical calculation natural frequencies can be gained with normal and tangential stiffness of LRG. Finally, the accuracy of the theoretical mode can be verified by dynamic test of LRG.

This paper addresses a worker assignment problem where multi-skilled workers perform a set of tasks independently and without walking and work sharing between workstations. A real case study is considered in this work. This problem is solved as a nonidentical parallel machines scheduling problem with stochastic processing time where each machine represent one worker. A simulation optimization （SO） approach, using a robust tabu search （TS） algorithm that is coupled with a simulation model, is proposed to minimize the maximum completion time （makespan）. The results is compared with this obtained by the using assignment method in the SETA Company.
