Abstract
Logistics is the transfer of goods from one place to another, mostly from the production house to the customers. A logistics network is a set of operations that involve designing, production, and marketing the goods. Cold-chain logistics are those that needed to be transported in a cold refrigeration right from the production house to the customer. A secured networking model is essential to handle the logistics networks. In this article, we are going to see an intelligent secured networking model to identify the optimal path for cold-chain logistics to hospitals. The optimal pathfinder is used to find the path between point A to point B, which is short and best. It also considers the road traffic and cost of transport. The cold-chain logistics to the hospitals include medicines and vaccines, which are to be stored at a particular temperature. Thus, path optimization is more essential in cold-chain logistics to hospitals than other types of logistics. In this research, the bee-ant optimization algorithm (BAOA) is proposed to perform the intelligent transportation to the hospitals. The proposed algorithm is compared with the existing ant colony optimization (ACO), bee colony optimization (BCO), and neural network model. From the results, it can be observed that the proposed algorithm shows 98.83% for the accurate delivery of logistics to the hospitals.
1. Introduction
While analyzing the cold-chain improvement in China, it focuses on three particular fields: commerce electronics, food manufacturing industries, and shopping malls. Here, the author of Ref. [1] had a look at terminal logistics serving centers that are insufficient locally. To reduce the insufficiency, he developed different schemes to manage those logistics spaces. In Ref. [2], the author brought a new idea to implement cloud computing and big data methods to improve fresh food management. This algorithm would also increase the traffic control under transportation and analyze the time required by a refrigerated vehicle with the help of parallel programming. Income management is one of the everyday things for every software company. In that case, cloud computing may cause a tremendous technological change in hardware and software companies. To identify the multiple types of data that can be collected and anatomized by interpreters across the cold chain, the ICT structure is needed to enable data capture and how to use the data for decision-making in cold-chain logistics. Data capture involves several types of data, which corresponds to products and processes. Most systems aim at collecting temperature or ambient-related data [3].
2. Literature Review
By the 1950s, VR (virtual reality) had been introduced to this world and by 2021 had developed the growth of graphics, programming, computation technology, and other software programs. Reference [4] demonstrates the actual process of virtual reality and also analyzes its value under cold-chain logistics. Food management is one of the significant recovering fields normally. Every food has a limited period to complete its life cycle. Within the end of its lifetime, it should sell it out to any customers. The authors in Ref. [5] have provided a process for the involvement of cold-chain logistics in all other fields. With the help of cold-chain logistics, there are some possibilities to check the quality of the product. Using such technology makes it possible to scan a product to identify its quality. They are following that Ref. [6] brought us a massive algorithm with an accuracy statement that explains the use of cold-chain logistics after implementing quality control. By presenting a navigating model, the author has described its purpose under the rise of sensor management, processing, and analyzing the data stored and merging it with real-time applications. Here, the dynamic programming algorithm is shown with its results by improving the run time and accuracy, finally demonstrating the output short-range ship management and wave-field problems have been rectified [7].
While traveling, people face different problems on their roads; this will not affect the ordinary traveler. When the same problem is confronted by a delivery truck driver or any other driver, it will affect their work. According to Ref. [8], the author has explained an algorithm named Dijkstra-GA, which is used under the path distribution from a cold-chain logistics. Using IoT (Internet of Things) creates a platform that connects several devices under the same platform. In that case, once we connect the devices under an application or a network, the connections between devices are made more robust, which automatically increases the controllability. This would help to make further operations with the help of cloud-based development [9]. There are different sections in the level of transportation; for example, if a vaccine is to be transported from one country to another country, then under the shifting place and preserve the vaccine, they would take different actions. This kind of activity is cold-chain equipment; through Ref. [10], the author gave us an enormous explanation of the cold chain and its improvement in China. In recent days, artificial intelligence has gained much value, so by utilizing it, technical engineers are trying to create automated things even for business management. If such things happened, robotic process automation would result in a robust and better decision-making platform. This article represents the clarity under key distributions of particular literature and its benefits [11]. By the development of technology, it automates the level of studies for the children, in that way here the author has a detailed architecture of logistics Internet of Things (IoT); after crossing over hundreds of articles, he came to a conclusion about logistics and started to classify it according to potential directions [12]. Finally, there is an actual relationship between the Internet of Things, logistics cloud chain, and technological developments. As a collaboration with several authors, the final paper has been started with different concepts such as virtual reality, machine learning, artificial intelligence (AI), and at last related to the logistics cloud chain with the future results [13]. The main problem in the electric vehicle routing problem will be carrying the products in spite of the heavy traffic, and the introduction of the new ant colony algorithm will help in the same distribution of the vehicles in the congestion period given the correct arrangement of all the products in a cost-effective way [14, 15].
3. Motivation of the Study
Cold chain logistics is the safe repository for managing of temperature-sensitive goods from one place of manufacture to the point of consumption. In this process, vehicles but rather warehouses equipped with cooling systems were used. With the support of cold-chain logistics, foods such as processed food, medicine, blood, eye, and kidney are safely transported to a consumer. People will investigate the path optimization technique of cold-chain logistics vehicles based on the improved evolutionary algorithms in this scientific report. The cold-chain logistics vehicle’s plan is important to reaching consumers in less time, distance, and cost. Routes are chosen based on data from road transportation. Path optimization algorithms are used for this. The bee-ant optimization algorithm (BAOA) is a type of artificial swarm intelligent technology that is based on bee and bee colony behavior. The cold-chain logistics path is optimized only with the aid of digital technology but instead Global Positioning System (GPS) technology. For the transportation of temperature-sensitive goods, the best short route is discovered. The primary objective of this research would be to shorten the duration, distance, and cost associated with transportation.
4. Proposed Model
Networking models are created beforehand to ensure the smooth flow in the logistics movement that performs the best as represented in Figure 1. The networking models are used to find the three most important factors. They are as follows:(i)Functionality: the sum or any aspect of what a product, similar to a software operation or computing device, can do for a user.(ii)Cost involved: product costs can include a variety of charges, similar to labor, raw stuff, consumable manufacturing inventories, and general outflow. Total product costs can be determined by adding together the total direct stuff and labor costs as well as the total manufacturing outflow costs.(iii)Customer satisfaction: how happy clients are with a company’s products, services, and capabilities is determined. Customer satisfaction information, including inspections and conditions, can help a company determine how to enhance or changes its products and services.
Before implementing a logistic network, these factors are to be considered to create an efficient, cost-effective way of logistics. There are various types of modeling techniques that are used to deliver the best customer service with good profit at the same time with reduced cost of the logistics handling. In this research, optimization modeling to arrive at an intelligent secured networking model to identify the optimal path for cold-chain logistics to hospitals is considered for evaluation.
The optimization method makes use of mathematical formulas to find a better solution in the cold-chain logistics for hospitals. This method is based on assumed data:(i)Number of production units: a process, line, system, conditioning, or approach, or a combination or series, therefore, are used to produce a product (or family of products). A production unit is not the process or the product. It is the combination of the process and the products produced by that process.(ii)Number of distribution centers: A distribution center is a product storehouse and shipping structure that stores goods a company produces. Distribution centers are a crucial part of the distribution chain for products, order fulfilment, and storing produced goods previous to their payload to wholesale, retail, or clients.(iii)Inventories to be maintained: effective inventory management lies nearly between these two axes. While it requires further work and planning to achieve an effective operation process, your gains will reflect your effort.(iv)High-level customer satisfaction: by surpassing their introductory expectations, you will achieve an advanced position of client satisfaction. For example, delivering a remarkably fast and super-friendly and helpful service is one way to exceed basic prospects. Another is to give products and services, which do further than your clients hope.
Linear programming is one of the most used types of optimization model in logistics networks. This method involved optimized use of the resources to arrive at maximum profits. Artificially intelligent computer systems are used to carry out the linear programming method to deliver the best result. This method is very much useful to meet the supply and demand between the two ends. Thus, there is a proper flow of goods from the production units, distribution centers, and hospitals. Thus, path optimization is more essential in cold-chain logistics for hospitals.
Medicines and their related equipment have to maintain a certain room temperature to function properly. In this regard, the production units, distribution centers, inventories, and also transportation systems should be equipped with the required specifications. It is easier to monitor the temperature when the product is in static case similar to the first three locations. However, the process is highly challenging during transportation. To overcome this challenge, cold chain logistics concepts are implemented to monitor the temperature on the move; additionally, bee-ant optimized algorithm is implemented to find the optimal path for transportation. In the proposed algorithm, the bee optimized algorithm is implemented in the forward pass and the ant optimized algorithm in the backward pass. During the forward pass, the optimal pathfinder has to do only the process of finding the path and it should be quicker. The reason the bee optimized algorithm is that the bee has the property to find the shortest path to the food resource from the location of the hive, whereas, during the backward pass, transportation of the material is considered in concern to the logistics. Ant optimization is chosen, as the ant generates the chemical compound named pheromone and it has the property of evaporation. This concept can be interlinked with the cold-chain property of monitoring temperature. When there is a change in the temperature during the transportation, as an alternative arrangement, another logistics can be chosen to continue the process. Hence, the combined model of the bee-ant optimized algorithm is proposed.
5. Proposed Work
The optimization model improving supply network efficiency and performance to give customers what they want, when and where they want it while making the business profitable and sustainable appears to take some influencing effects into consideration to represent the real situation, including time-varying transportation, online traffic, traffic levels, customer time consumed, sleekness of innovative products, but it also gives a pathway to charge delay time. The bee-ant optimization algorithm was created to help with the electric vehicle routing for logistics vehicles (EVRP).
It was inspired by the natural rustling actions of honey bees, to find the optimal result. The algorithm performs both an exploitative neighborhood search combined with an arbitrary explorative search. The bee-ant optimization algorithm has been successfully applied to several optimization problems such as multiobjective optimization, neural network training, manufacturing cell arrangement, job shop scheduling for a machine, data clustering, optimizing the design of mechanical factors, image analysis, and supply chain optimization. According to the simulation results, the proposed scheme can effectively prevent congestion problems during the delivery process, lower total distribution costs, and improve the efficiency of a cold-chain logistic distribution system with new items.

The optimization method employs the use of intelligent wireless sensor networks for the online ordering of materials, which necessitates the preservation of temperature during resource transportation. This is accomplished through the use of intelligent sensor devices attached to the transporting vehicle to continuously monitor the status of the resources. Table 2 shows the minimum distribution, travel distance, and energy consumption for transportation.
