A proper replenishment strategy is a critical enabler in the success of increased revenue, net profits and customer service. Inventory management requires constant and careful evaluation of external and internal factors and control through planning and review. In order to control the inventory, one major requirement is to provide efficient replenishment technique such as jointly replenishment of products. Searching for efficient replenishment techniques is a common and usually a mandatory topic for the organizations. We consider inventory systems with multiple products in the presence of volatile demand and jointly incurred order setup cost. In this thesis, a new adaptation of spreadsheet heuristic for volatile environment is presented. The simplicity of application of spreadsheet method and its efficiency enables us to consider its modified version for the joint replenishment problem under volatile demand. The principle of the procedure is to find a balance between the replenishment and holding cost for jointly replenished items. The real business data is conducted to evaluate the performance of the heuristic. The study shows that the proposed algorithm performs well in comparison with well known RAND heuristic for the numerical data. Additionally, the importance of using volatile demand strategy over deterministic strategy is also highlighted with a calculation. The proposed strategy gives higher customer service level which means lower unmet customer demand. Owing to the simplicity and effectiveness of the proposed algorithm, we believe that it can be applicable in volatile demand environments.
