# Pricing Strategies of Logistics Distribution Services for Perishable Commodities
## 6 Conclusions  
This paper has presented approaches for handling the decay in perishable goods distribution as well as the sensitivity characteristics of consumers to delivery time and service satisfaction, using four different pricing models that are the fixed pricing model and dynamic pricing model with and without time constraints, respectively. Then, the profit model of the logistics service provider is constructed and the corresponding optimal pricing and average profit are obtained. The influences of the decay index, delivery time, and consumer service satisfaction on distribution pricing are analyzed. The following conclusions are obtained. (1) The relationship between the optimal price and the decay index under four pricing models are as follows: Under the fixed pricing model, the larger the decay index, the lower the distribution pricing of perishable commodities; under the fixed pricing model with time constraints, the larger the decay index, the lower the distribution pricing; and the dynamic pricing model has the lowest distribution pricing. Optimal distribution price first rises and then decreases, at the same time, the greater the decay index, the greater the extent of decline when the optimal distribution pricing drops. Under the dynamic pricing model with time constraints, the relationship between the decay index and the optimal pricing is same to that under the dynamic pricing model. (2) The relationship among optimal price, customer service satisfaction, and storage cost of perishable goods under the four pricing models are given as follows: Under the fixed pricing model and fixed pricing model with time constraints, the optimal price increases with the increase of customer service satisfaction and storage cost; under the dynamic pricing model and dynamic pricing model with time constraints, the optimal price increases first and then decreases. Within the increasing range

Within the decreasing range of distribution price, the distribution price increases with the increase of customer service satisfaction and storage cost. The greater the increase in consumer service satisfaction and storage costs, the greater the reduction in distribution price. (3) Comparing the fixed pricing model with the dynamic pricing model, we found that if \(\bar{t}\) satisfies \(V_{\bar{t}}+h\bar{\bar{t}}\big{(}T-\bar{\bar{t}}\big{)}=h+\frac{(V_{0}-V_{T})}{ \Delta T}\), the distribution price under the dynamic pricing model is higher than that under the fixed pricing model for \(0<t<\bar{t}\). For \(\bar{t}<t<T\), the distribution price under the dynamic pricing model is lower than that under the fixed price model. (4) Comparing the four pricing models, we found that the average profit of the logistics service provider under the fixed pricing model with time constraints is higher than that under the fixed pricing model. The average profit of the logistics service provider under the dynamic pricing model with time constraints is higher than that under other three models. In addition to these conclusions, the following suggestions are given for logistics providers:  
1. Consumers are more inclined to choose the dynamic pricing model either with or without time constraints. For two dynamic models mentioned above, consumer service satisfaction is more important to the quantity of distribution, and it indirectly affects the overall profit. Therefore, for these two models, logistics service providers should pay more attention to the response of consumers, or take more active measures to improve their own consumer service satisfaction. 2. Logistics service providers can choose mass distribution of perishable commodities under the same storage conditions, which will reduce the storage cost of perishable commodities per unit in the distribution process, and then increases their own profits.
