In real-world problems, designing Cellular Manufacturing System (CMS) face the imprecise or fuzzy nature data such as demand uncertainty. Due to these considerations, this study proposes Dynamic CMS model under demand uncertainty. Dynamic CMS is a CMS where its machine-cell configuration may change during the planning period due to the demand changes. This model optimizes Cell Formation, Production planning and Worker assignment concurrently. Objective function of this model is minimizing total expected cost consisting machinery depreciation cost, operating costs, inter-cell material handling cost, intra-cell material handling cost, machine relocation costs, setup costs, back order cost, holding cost, subcontracting cost, worker assignment cost. This model determines optimum cell formation, production optimum policy (like determining quantity of production, inventory and subcontracting parts) and workers optimum assignment to manufacturing cells in each rolling period. The proposed model is an integer linear programming model. Numerical examples are elaborated in the paper to depict the influence of changes in fuzzy demand and fuzzy capacity on changes in total cost, and in production and worker optimum policy
