## Abstract

In recent years, the development of e-commerce new retail formats is in full swing, and the terminal distribution has become a hot research topic under the background of new retail. The accuracy of the community navigation map is related to the low cost and high efficiency of terminal distribution and then affects the development of new e-commerce retail. However, in large communities, the existing navigation map software can only locate the main entrance of the community, and there is a lack of effective positioning for the location of buildings. Therefore, based on the existing navigation map, this paper expects to correct its application defects and carry out optimization design from the design principle, design idea, product function, product customization, and product application effect, so as to make the community navigation more accurate, faster, and more efficient, to help the low cost and efficient development of door-to-door distribution under the new retail of e-commerce.

## Body

## 1. Introduction

In November 2016, the general office of the State Council issued ‘The opinions on promoting the innovation and transformation of physical retail’: “To guide physical retail enterprises to improve the information level gradually, to integrate the advantages of offline logistics, service, and experience with the online business flow, capital flow, and information flow, and to expand the intellectualization and networking total channel layout (Opinions on promoting the innovation and transformation of physical retail issued by the general office of the State Council (GBF [2016] No. 78)).” The new e-commerce retail has entered a fast development stage. In May 2020, General Secretary Xi proposed “to build a new development pattern with domestic circulation as the main part and domestic and international double circulation promoting each other (On May 17, 2020, Jinping Xi’s speech about building a new development pattern in which domestic and international double cycles promote each other).’’ The double cycle-new development pattern is the path choice of China’s economic modernization development under the COVID-19 spreading situation. There is a great and far-reaching significant meaning of new e-commerce retail in helping the development of China’s double cycle social economics.At present, e-commerce new retail and the terminal distribution have become one of the most concerned economic topics by domestic experts and scholars. Many experts give opinions and suggestions on the innovations of new retail business model and logistics model [1, 2] and make some research studies on the integration development of new retail, agriculture, tourism, and other industries [3]. The views of some scholars on the logistics distribution are shown in Table 1. Mainly, scholars often use models and algorithms to optimize distribution routes, use platform constructions and technologies to study distribution problems, and give distribution development countermeasures, distribution mode selection, and so on. But in terms of the navigation map tools of logistics distribution at the e-commerce new retail of closely following the background of double cycle-new development, there is a lack of accurate positioning of community entrance and internal building location.Table 1

It can guide the delivery personnel to reach the door of the customer’s building through the gate in the fastest time and shortest path, so as to improve the accuracy and timeliness of distribution. The existing navigation maps can only locate the main entrance of the community or the main gate of the community. The buildings’ locations in the community rely on the experiences of the distributors, which is time-consuming and inefficient. The accuracy of the community navigation map is related to the low cost and high efficiency of terminal distribution, so as to promote the development of new e-commerce retail.Based on the new development-double circulation pattern and through practical investigation and analysis, moreover, based on the overall situation of the current e-commerce new retail logistics distribution navigation maps, this paper optimizes a navigation map that can accurately locate the entrance of the community and the location of internal buildings, hoping to help the healthy development of e-commerce new retail distribution, to make suggestions, and to promote the efficient development of domestic large circulation and international and domestic double circulation.


## 2. Analysis on the Development of E-Commerce New Retail Market and Terminal Logistics Distribution in China

E-commerce new retail is an innovation of the traditional retail model, which integrates online sales and offline services under the support of advanced information technology means such as the Internet, Internet of things, cloud platform, and big data, which is an organic integration of a series of links such as product presales consulting service, in-sales order purchase service, and after-sales logistics distribution service [12]. Since 2016, the policy guidance was put forward at the national level, and the e-commerce enterprises led by Taobao and T-mall have deployed online and offline, the “new retail” has shown an irresistible trend to reshape the retail format. After analysing the logical structure of the new retail (as shown in Figure 1), we can see the traditional customer group has been gradually attracted from offline to online, and the digital customer group has also increased its proportion with the help of mobile Internet and terminal products, the new retail has increasingly become the core of the sales service field.Figure 1
The logical structure of new retail Omni channel.By the end of 2019, the sudden arrival of COVID-19 led to the stagnation of many industries in the country. In 2020, the total retail sales of consumer goods declined, but the national express delivery volume reached 83.35789 billion pieces, with an annual growth rate of 31.22% and also maintained a growth rate of 29.92% in 2021 (as shown in Table2). Meanwhile, according to the report on China’s fresh retail market development in 2020, the order volume of China’s real-time logistics industry in 2020 was 24.37 billion orders, with a growth rate of 31.8% (as shown in Figure 2). In 2020, the number of instant distribution users in China was 506 million, with a growth rate of 20.19% (as shown in Figure 3). E-commerce “new retail” has developed rapidly against the trend by virtue of “online order + offline logistics distribution” and has become a new force for the development of large cycle and double cycle in China [13]. With the rapid development of new e-commerce retail, the market has greater demand for warehouse and distribution and higher requirements for distribution timeliness of “national 24-hour delivery and global 72 hour delivery.” A lot of fresh food, retail, express, and e-commerce enterprises have taken advantage of the integration of warehouse and distribution to advance the warehouse (prewarehouse mode) and distribute nearby to meet the requirements of distribution timeliness [14].Table 2

The chart of total statistics and growth of China’s JIT distribution orders from 2014 to 2020.Figure 3
The chart of scale and growth rate of China’s JIT distribution users from 2014 to 2020.According to the statistics of the questionnaire data, the author thinks that in the new retail terminal logistics distribution business, there are various factors affecting customers’ shopping experience and the impact of distribution effectiveness (distribution prescription) is 20%, following the impact of commodity price (as shown in Figure4). The distribution efficiency of distributors is also affected by many factors. Among them, not being familiar with roads accounts for 40%, which is the main factor affecting the distribution efficiency of distributors (as shown in Figure 5). Unfamiliar with roads are the main factors affecting the distribution efficiency of distributors, and the distribution timeliness affects the shopping experience of customers. Unfamiliar with roads does not mean unfamiliar with trunk roads but unfamiliar with community roads and even roads inside the community. There are some large communities with dozens or hundreds of buildings. It is very difficult to find a route to deliver goods to the door by relying on the impression of the delivery staff. It will be the most ideal if there is a navigation map that can accurately locate the location of the customer’s building, by which the delivery personnel will directly follow the guidance of the navigation software and choose the shortest route from the nearest entrance to the customer’s building quickly and efficiently.Figure 4

## 3. Market Mainstream Navigation Software Products Have Defects in Accurate Positioning of Customer Positions

By comparing the distribution time under different distribution modes (as shown in Table3), we find that the new e-commerce retail requires a very short distribution time, and it is difficult for existing distribution conditions to meet the requirements. Although there are many mature navigation maps products on the market, such as Baidu map, Tencent map, Gaode map, Google map, and Sogou map, which are located at the approximate location of the community or the main entrance and exit of the community, whose basic data can not meet the information data required by the delivery personnel. For example, the author uses the Baidu map to navigate “Building 2, Nanwan International Community, Zhuhai, Guangdong.” The search result interface of the Baidu map shows that there are 8 gates, but it is unknown which gate the two buildings are close to (as shown in Figure 6). If the delivery personnel randomly choose a gate to enter, they need to find themselves or seek help from others when they arrive at building 2, which is time-consuming and laborious.Table 3

The display interface of searching by Baidu map.Therefore, if a larger community has multiple entrances and exits in the south, east, north, and west, different buildings are close to different entrances and exits. If you uniformly enter the community for distribution from the main gate or an entrance and exit, the distribution personnel need to rely on experience or inquiry in the selection of distribution routes within the community, which often wastes time and prolongs the distribution timeliness. Due to the lack of more detailed basic data such as the most suitable entrance recommendation and the location display of buildings in the community, the existing mature navigation software can not accurately locate the buildings of the target customers of terminal logistics distribution, and the optimal path selection in the community is lack of optimal and reasonable planning, and the shortest route selection is lack of planning and arrangement.


## 4. Optimized Design Process of Community Accurate Navigation Map

The Accurate Community Navigation Map is a map based on the practical problems of the e-commerce new retail logistics distribution navigation software, such as unclear navigation positioning, serious waste of distribution time, low distribution efficiency, and optimized design by collecting the infrastructure information within the community through 360° panoramic car. It can accurately locate the navigation map of the nearest entrance and internal building location of the community. It is generally applicable to different scenarios such as community fresh food distribution, fast food distribution, e-commerce new retail small parts distribution with fixed distribution scope and area. If a delivery clerk receives a delivery order, the delivery clerk must deliver the fast food to the customer within 1 hour or even 30 minutes to ensure that the fast food is fresh and warm. The accurate navigation map of the community can guide the delivery personnel to arrive at the most suitable gate in the fastest time, arrive at the customer’s building in the shortest path, and deliver meals to the door, so as to improve the accuracy and timeliness of distribution.


### 4.1. Product Design Principle

When a distributor goes on joint distribution to multiple customers, if the sum of the demands of all customers on the same line is not greater than the rated load capacity of a vehicle, then the vehicle will be equipped with all the goods required by customers, and the goods will be delivered to each customer in turn according to a predesigned best line. At this time, the mileage saving method is adopted in the design of the distribution line.As shown in the left programme of Figure7, (a) distribution point P is used to deliver goods to a customer point A, then return to the origin P, and then deliver goods to another customer B. The total distribution distance is 2 (a + b). The route is repeated and bypassed, resulting in overtime distribution, high distribution cost, and low distribution efficiency. From the right programme of Figure 7, we can see that multiple customers points A and B are connected by one distribution point P, which is first distributed to one customer point a and then patrolled back to another customer point B. The total distribution distance is (a + b + c). When there are no special provisions on road conditions, the vehicle running distance that can be saved is (2a + 2b) − (a + b + c) = (a + b − c). According to the theorem that the sum of the two sides of the triangle is greater than the third side, (a + b − c) > 0, then this saving is called “mileage saving.” Therefore, through itinerant distribution, the distribution distance can be saved, which is conducive to the distribution staff to improve the distribution efficiency and save the cost [15].Figure 7
Display of optimized path of mileage saving method.The accurate community navigation map product is designed based on the principle of mileage saving method, which collects data sink to more refined communities and buildings in the community and marks the data pertinently. The terminal distribution route is more reasonable, which is conducive to saving distribution time and improving distribution efficiency.


### 4.2. Product Design Ideas

(1)
Relying on existing navigation maps such as Baidu map data and to accelerate the rendering engine to convert the static map on the drawing into a dynamic map. After the field investigation of the community streets, the corresponding distribution map is made. In the initial stage, the distribution map can be used as a guide, and in the later stage, the modeling technology is used to simulate the overall real effect of the community.(2)
Mileage saving algorithm and map block loading technology are used to analyze and calculate the optimal path planning. Divide the building range of the community according to the community. In the framework of the whole large community area, the detailed division of small areas is studied. The product function focuses on the distribution of buildings in the fixed coding area, the orientation of the entrance, the road division of the fixed area, and so on. The more detailed the information marked on the map, the more conducive it is for the distributor to achieve rapid positioning and quick route in the distribution process.(3)
Add voice prompting technology and a voice engine to play the voice system for delivery personnel in real time.


### 4.3. Product Realization Function

(1)
Real time accurate positioning and navigation. Through high-precision positioning technology, the delivery personnel can know where their real-time location is by using GPS positioning, while the community's accurate navigation map matches the best route of the community and quickly reaches the building of the target customer.(2)
In intelligently searching, the delivery personnel can directly enter the destination. The accurate navigation map of the community will quickly provide users with relevant search services. At the same time, it will also provide common community navigation options according to the user’s use records to avoid repeated input, so as to enhance the user’s stickiness.(3)
Voice prompt and operation. In order to improve the user experience of the distribution personnel, the navigation app relies on the Internet. It can receive instructions through voice and provide voice broadcasting for the distribution personnel according to road conditions and other precautions, so as to improve the distribution efficiency of the distribution personnel and ensure the safety of the distribution process.


### 4.4. Product Realization Process and Cost Analysis

In the early stage of the product, team members survey the basic information of geographical location and draw community map data. Compared with the existing navigation maps in the current market, this community accurate map navigation product pays more attention to the sinking of basic data and user experience. According to the market research and analysis and the actual situation, the exclusive basic data community map of the distribution personnel in a distribution area is specially customized. The basic data contain the specific information required by group users, such as clear and detailed building distribution, entrance and exit conditions of residential areas and communities, and optimal path planning within major communities. Make pictures through network drawing and present them on the handheld terminal to connect with the new retail terminal distribution platform of e-commerce. The product is mainly aimed at users and is a platform distributor. The product has achieved good results in the initial practical application. At this stage, the first generation products have been used by takeout distributors in some regions.Taking the Shenda Store of a supermarket in Shenzhen as an example, we professionally customize and design accurate community map products. The implementation process is as follows:(1)
Draw a regional map within the planned area with a radius of one kilometer to three kilometers to complete the distribution task for the target distribution point (as shown in Figure8). Firstly, the distribution of road conditions and target customers are obtained through market research, so as to set a reasonable distribution radius. Secondly, a new distribution range of the front warehouse is planned. The distribution range of the front warehouse of each enterprise is closely connected to ensure that there is no dead angle for customers to place orders and that customers can locate in real time in the region in an all-round way.(2)
Under the large-scale planning and design at the urban district level, the coding area division is carried out with the main urban road planning as the dividing point, so that the distribution staff can understand the scenery in the area in more detail. Once a target customer is set, the delivery clerk can make information reference according to the longest distance and the longest distance time given by the accurate community map, make a reasonable choice of receiving orders, and also help the delivery clerk to combine orders, take orders, and send orders well, so as not to take orders blindly, resulting in overtime.(3)
Divide the small blocks and then divide the community buildings.The research focuses on the distribution of buildings and the orientation of entrances in the fixed coding area. The more detailed the information marked on the map (as shown in Figure9), the more conducive it is for the distribution personnel to achieve rapid positioning in the distribution process. By dividing the roads into the fixed area, we can find more convenient and fast roads for the distribution personnel in the distribution process. The delivery time can be saved through more convenient and fast roads to better improve the customer’s sense of service experience.(4)
The entrance orientation, parking location, and building distribution of community buildings shall be marked in detail. Now most communities will set aside many gates. The study found that under normal circumstances, a community will set aside 2–4 gates in the early stage of construction. These gates facilitate each household to quickly reach their own place, but for a delivery clerk who does not know the real scene of the community, it will take 5–8 minutes to find the entrance and exit gate for the first time. If the specified delivery time is about 30 minutes, 5–8 minutes will lead to the reduction of the distribution efficiency of the distribution staff, which is not conducive to the growth of the single quantity of the distribution staff, which will also have a certain impact on the income of the distribution staff. The simple map identification can help the delivery personnel locate and identify the area quickly and accurately. Especially in the situation of COVID-19’s normalization and prevention and control, many communities are still closed management. When they enter the district, they will give a specific access gate. If the distributor goes to the wrong gate area, it will also cause great waste and loss of time.Figure 8
Identification map of distribution scope.Figure 9
Electronic hand-drawn community map of a community in Shenzhen.Taking a community in Shenzhen as an example (as shown in Figure9), the accurate navigation map of the community uses lines and colors to represent the streets, so as to increase the discrimination. Different thicknesses indicate different widths of the streets; Through the annotation of different colors, it can be better identified. When the deliveryman checks the map and selects the route, he can quickly locate it in a short time. After receiving the order, the delivery clerk needs to deliver the goods to the two customers of building 45 and building 51 in the community. According to the principle of mileage saving method, the delivery clerk will load all the goods of the two customers at one time and navigate to the destination according to the accurate community map navigation software. Due to the requirements of epidemic control, the community has four entrances and exits: south gate, south second gate, east gate, and guiba entrance and exit. However, the conventional navigation map will directly navigate to the south gate, but building 45 is closer to the entrance of the South second gate. According to the accurate community map navigation, the delivery clerk should enter the community from nanermen, first deliver the goods to 45 customers, then deliver the goods to 51 buildings, and then choose to leave the community from Dongmen. The route is the best, the time is the shortest, and the delivery cost is the lowest. Due to the requirements of epidemic control, the community has four entrances and exits: south gate, the second south gate, east gate, and guiba entrance and exit. However, conventional navigation maps such as the Baidu map will directly navigate to the south gate, but building 45 is closer to the entrance of the south second gate. According to the accurate community map navigation, the delivery clerk should enter the community from nanermen, first deliver the goods to 45 customers, then deliver the goods to 51 buildings, and then choose to leave the community from Dongmen. The route is the best, the time is the shortest, and the delivery cost is the lowest.Although this navigation map is not a newly developed one but is optimized based on the existing navigation software, it still takes a long time, cost, and energy to explore and investigate the location of community gates and buildings. Taking a community in Shenzhen in Figure9 as an example, the investigation team spent half a day investigating and clearly identifying the location of community buildings. However, because the location of community buildings will not change, once the logo can benefit for a long time, it is also valuable, necessary, and worthwhile.


### 4.5. Product Application Effect

Through the team’s practical operation and investigation, the navigation software with an accurate community map has indeed improved the distribution efficiency, with the punctuality rate reaching 95.2% and reduced the average order length from 25–30 minutes to 21.1 minutes, greatly improving the distribution efficiency of a single distributor and greatly increasing the salary of the distributor; it has actively promoted social employment and labor productivity (as shown in Table4).Table 4

However, conventional navigation maps such as the Baidu map will directly navigate to the south gate, but building 45 is closer to the entrance of the south second gate. According to the accurate community map navigation, the delivery clerk should enter the community from nanermen, first deliver the goods to 45 customers, then deliver the goods to 51 buildings, and then choose to leave the community from Dongmen. The route is the best, the time is the shortest, and the delivery cost is the lowest.Although this navigation map is not a newly developed one but is optimized based on the existing navigation software, it still takes a long time, cost, and energy to explore and investigate the location of community gates and buildings. Taking a community in Shenzhen in Figure9 as an example, the investigation team spent half a day investigating and clearly identifying the location of community buildings. However, because the location of community buildings will not change, once the logo can benefit for a long time, it is also valuable, necessary, and worthwhile.


## 4.5. Product Application Effect

Through the team’s practical operation and investigation, the navigation software with an accurate community map has indeed improved the distribution efficiency, with the punctuality rate reaching 95.2% and reduced the average order length from 25–30 minutes to 21.1 minutes, greatly improving the distribution efficiency of a single distributor and greatly increasing the salary of the distributor; it has actively promoted social employment and labor productivity (as shown in Table4).Table 4
