How to reserve fruit and vegetable digestion technology

The research on fresh vegetable inventory was first started by T.M.WILL in 1957, when fashion items became obsolete at the end of the inventory week. After that, the researchers think that the consumption of fresh vegetables has a negative exponential function with time. On the basis of this study, a fresh vegetable inventory model with negative exponential function is put forward, which has been cited by subsequent fresh vegetable inventory researchers. After that, many scholars who study the change of fresh vegetable inventory level have studied the perishable goods inventory model with this formula as a reference.

Raafat reviewed the research status of fresh vegetable inventory in 199 1 and 200 1 respectively, and Goyal also studied the fresh vegetable inventory strategy with time-varying demand. The purpose of studying the inventory problem of fresh vegetables is to formulate the corresponding inventory strategy. The decision variables are mainly the replenishment period (time interval) and replenishment quantity of fresh vegetables. In decision-making, costs (generally including holding costs, acquisition costs and out-of-stock costs) are often used as criteria for setting objective functions.
