Abstract: In this study, an order level inventory model, continuous in unit and time is developed for deteriorating items. The model is developed under deterministic demand, instantaneous delivery. In the first section order level inventory model for deteriorating items with single warehouse is developed where shortages are taken into consideration. Shortages are partially backlogged and partially lost sales. Maximum profit is calculated. An example is given to illustrate the model. In the second section, order level inventory model for deteriorating items with two warehouses is developed. Shortages are partially backlogged and partially lost sales. Minimum inventory cost is obtained and profit is maximised. An example is given to illustrate the model along with sensitivity analysis.
Keywords: partial backlogs; lost sales; product deterioration; warehouses; shortages; order level inventories; deteriorating items; deterministic demand; instantaneous delivery; profits; inventory costs; profit maximisation; sensitivity analysis; advanced operations management.
