What is the study of distribution model?

Current situation of "last mile" distribution of domestic e-commerce logistics. At present, the "last mile" distribution of e-commerce logistics in China is not ideal, and there are many problems, especially in the shopping season such as holidays. It can be mainly summed up in two aspects. The quality of delivery service is not high. The low quality of distribution service is mainly manifested in three aspects. First, the timeliness of goods distribution is poor, that is, the courier can't deliver the goods to the customer within the agreed time window; Second, the delivered goods are damaged; Third, the courier's service attitude is poor. Analysis, for two reasons. First of all, in order to stimulate the enthusiasm of couriers and reduce costs, general companies take piecework wages for couriers. The courier hopes to complete as many delivery tasks as possible in a unit time. For example, in order to shorten the delivery time of each package as much as possible, couriers often agree with customers on a time window, but due to traffic jams and other reasons, the goods cannot be delivered on time, resulting in customer dissatisfaction or delivery failure. In the latter case, the courier often puts the parcel in the duty room of the residential property to complete the delivery work as soon as possible, which leads to the failure to guarantee the safety and integrity of the goods. In addition, when the delivery work cannot be completed as soon as possible, the courier's mood will deteriorate, thus affecting his attitude towards the subsequent delivery service. Secondly, in order to reduce the distribution cost, the hardware of the "last mile" distribution of domestic e-commerce logistics is relatively poor, and electric tricycles are mainly used as distribution tools. However, the size of the carriage of a tricycle is generally small. In order to save time, couriers often try to package the delivered packages at one time. Problems such as extrusion and overload are very serious, which are neither standardized nor safe. When the weather is bad, the problem is more prominent, and the safety of the package cannot be guaranteed. The traceability of distribution information is poor. At present, crowd tactics are widely used in the "last mile" distribution stage of domestic e-commerce logistics, and the degree of informatization is low. For example, many logistics companies are still handing over various functional blocks with multi-link documents; Parcels are only scanned and registered in regional distribution centers, and couriers generally don't have scanning terminals, so the accuracy of information such as when the goods arrive at customers and whether customers sign for them will be affected, which is not conducive to customers, e-commerce companies or logistics companies to track the delivered parts. Sometimes it's only when users complain that the delivered goods have not been delivered or delivered incorrectly, or even lost. It can be seen that with the development of e-commerce, the problems in the "last mile" distribution stage will be more severe, and even hinder the sustainable growth of domestic e-commerce.
