ذخيره سازي محصولات كشاورزي فسادپذير در شرايط عدم اطمينان

Agricultural Products Under Uncertainty

The stockpiling or storage of commodities plays a very important role in commercial and marketing services. This process by managing the time intervals between production and consumption, brings new synergy for goods and yields expected profits for producers. Such process by diminishing the wastes and increasing opportunity cost for products in different periods of time leads to credibility and incentive in market factors. It also amounts to prudent and efficient decision making in the field of production, consumption and distribution. Furthermore, this process by bringing necessary and proper adjustments in consumption and price level leads to food and economic security. The purpose of this paper is , by taking into account the special characteristics of perishable agricultural products, to review and analyse the factors which determine the level and magnitude of storage. To accomplish the task, first the theoretical background and literature are briefly reviewed and a simple model is introduced and at the next stage the model is extended to include other concepts such as rational expectations, uncertainty and cost per unit of storage.
