The withdrawal Kanban system, by capability of data transferring in supply chain reduces different types of the waists such as inventories level and unnecessary movements. To achieve the aims of lean production, the parameters of the Kanban system such as the number of Kanban should be determined properly. The number of Kanban problem is a multi-objective problem which should met the aims of producers and suppliers simultaneously. In this paper, the objectives and constraints of withdrawal Kanban problem has been determined based on a case study in automobile supply chain. A mathematical integer multi-objective model with non-linear objects has been developed. Two sets of solutions are generated by the optimization model. A simulation model is developed to check the possibility and validity of solutions. The simulation studies show that one of the solutions can reduce up to 46 percent the inventory costs while increase 11 percent transportation costs compared to the current state.

Just in time (JIT) production is a new approach and way of thinking in the management of industrial organizations, the principles and methods of which seek the complete and comprehensive elimination of wastage and the enhancement of productivity in all activities inside and outside the organization .Accordingly, the purpose of the present research is the comparative evaluation of the components of just in time production within the various industrial groups of Tabriz. The statistical population of the research includes 576 factories in the four industries-machinery and equipment , chemical substances and products , textiles , and electronics and the related equipment-in small and medium scales in Tabriz . The sample size has been 313 based on the relation in limited populations and through the use of relative stratified sampling method . The researchers have used a questionnaire in order to collect data , and the data have been analyzed by multivariate ANOVA. The results indicate that there is a difference amony the four industries regarding lean production components .
