The owned warehouse has a fixed capacity of W units; rented warehouse has unlimited capacity. Here, we hypothesized that the Block chain Economic Impact of the Coronavirus Pandemic Medicine Industry in Inventory Cost of Inventory in RW is greater than that in OW using PSO. The shortcomings of the economic impact of the Coronavirus pandemic Medicine industry are allowed and partially lagged behind, and it is assumed that Block chain’s economic impact of the Coronavirus medicine pandemic industry decreases over time with a variable deterioration rate and wastewater treatment cost using PSO. The effect of inflation was also considered due to the different costs associated with Blockchain applying the Economic Impact of the Coronavirus Medicine Industry Inventory System and wastewater treatment cost using PSO. The numerical sample is also used to study the behavior of the model using particle size optimization. The cost minimization technique is used to obtain expressions for total costs and other parameters. Many researchers have expanded the EOQ model to changing demand patterns. Some researchers have discussed the economic impact of inventory models in the Coronavirus industry pandemic with a linear trend in demand. A major constraint on the timing of the smooth time in demand is that it means uniform changes in the level of demand per hour. This rarely happens with any product on the market. In recent years, many models have been developed with a level of demand that changes dramatically over time.For seasonal products such as clothing, climatic conditions, etc. At the end of the season, it is noted that the demand for these items decreases exponentially for a certain initial period. Subsequently, the demand for products becomes stable, without decreasing exponentially. This type of statement is considered quite realistic. Such a scenario can be illustrated by the rate of ramp-type complaints. An important question about the economic impact of the package industry inventory theory of the coronavirus industry is how to address unmet needs that arise during shortages or stocks. In most development models, the researchers supposed that the deficiencies were whichever completely delayed or completely lost. The first case, known as an order or default case, is a case in which an incomplete request is ordered entirely. In the second case, also known as the lost sales case, we assume that the unrealized demand is completely lost. Also, in the event of a shortage, some buyers are willing to wait for an order while others will buy from other sellers. Often, customers experience delivery delays and may be willing to wait a short time to get their first option. For example, with modern, high-quality products and short product life cycles, the client's willingness to wait decreases with waiting time. Therefore, the length of time to wait for subsequent payment will determine whether the arrears will be accepted or not. In most cases in life, during a short period of time, the waiting period is longer, reducing the lag. Therefore, for real business cases, the delay rate should be different and depends on the waiting time for the next recovery. Many researchers have altered the impact of the policy on the ferry industry's calculation for the corona virus based on the partial delay rate.

Gupta Blockchain is a network technology, endowed with its ability to publicly verify, record and distribute transactions at an unaltered and encrypted rate. The technology is designed to maintain transactions in bitcoin, a digital currency that operate independently of a central bank. In short, Blockchain technology provide a platform for all bitcoin transactions -that is, creating or distributing records for millions, if not millions, of computers connected to networks around the world. As an activity with cryptocurrency manufacturers, Blockchain Technology offers greater security than the banking model and is the current online shipping process to open a bank for two to three days and transfer money from one account to another. Eliminate management costs. The term "Blockchain" comes from the "constraint" of legal and immovable transactions and how they are linked to a chain (disclosure) sequence. Hence the word "blockchain". The wastewater treatment industry varies widely in flow and structure, depending on factors such as production rate, special preparation, wastewater operations, and so on. All of these parameters mean that the final sewage contamination can be very different and vary over time. In general, these wastewater consists of the following: Large amounts of organic matter, many of which can decompose (alcohol, acetone, etc.) Slowly decomposing organic compounds and reject substances (aromatic compounds, chlorinated hydrocarbons, n.k.).Soaps and soaps and enhancements. Most wastewater is made with washing equipment at the end of the production process. It contains a small amount of other pollutants caused by water purification (reverse osmosis rejection and regeneration of ion resins), plant cleaning, laboratory sewage and so on. The best wastewater treatment methods produced by this type of industry will depend on each individual case, taking into account their major differences and the range of possible compounds. Particle improvement is initiated by a number of random solutions, and every one possible solution is given a random rate. A solution that can be called a particle has poured into the problem space. Every one particle follows its coordinates in the problem area of the best solution or prosperity achieve so far, the value of equilibrium is also preserved. This value is called pbest. Another outstandingworth set by the global version of the PSO is the best worth and its place is found so far by every particle in the population. This worth is called gbest.So, in each phase, the constituent part changes its speed to a more pleasant and beautiful one, this is the universal version of the PSO in which all particles, except the best, follow a solution known as nbest or gbest. The best extract from local particle topology is a process called the internal version of the PSO.

Step 2: "Start each pheromone trace with the same amount of pheromone and create a doable solution at random". Step 3: "Move the ants according to the pheromone paths to produce a viable solution". Step 4: "Repeat the third step for a number of ants". Step 5: "Update the pheromone based on the best possible solution in iterating the current algorithm". Step 6: "Repeat the third and fifth steps for a certain number of loops or termination criteria". Step 7: "Report the best solution". The manufacturer makes medicines and adds a QR code that contains basic information such as timestamp, name of the item, area and composition and expiration date. The data contained by the manufacturer is placed on a blockchain, making it easier for other partners to track the drug supply chain. When data is added to the blockchain, a hash ID is provided which can be used to track the exchange. (ii) Distributors send medicines to hospitals: When logistics providers deliver medicines to distributors, they can check the origin of the prescription using a hash ID stored on the blockchain. Distributors approve the medications received and carefully sign the exchange which is then added to the blockchain. Pharmacists receive drugs and check its source:Drug specialists are given drugs that they can track to understand their origin using a hash ID stored on the blockchain. With the exception of the possibility that an illegal trader attempts to sell counterfeit medicines with a forged identity card to specialists or patients, the exchange is considered invalid due to false information on the medicines. (iv) Patients buy medicines and scan the QR code to find its source: Patients can be assured whether the medicine they are purchasing is safe or not. By checking the QR code that is added to the medicine package with the portable application, they can learn more about its source even if it meets the quality guidelines. A hash ID associated with a QR code would bring data from the blockchain and patients can access basic details. The use of pharmaceutical block agreements will facilitate the visibility of the development and partners through which drugs or prescriptions travel in the store network. Better visibility encourages streamlined product flow and an efficient inventory management framework. Reduced counterfeiting losses: The use of blockchain can improve the clear visualization of the journeys of healthcare products from manufacturers to patients with digitized exchanges. In this way, it would be possible to re-examine the weaknesses of the production network and reduce the likelihood of counterfeiting and the costs associated with repairing the damage. Transparency to improve accountability: The procurement and transport of healthcare products through the supply chain can be closely monitored. Furthermore, it is possible to keep track of the stakeholders or partners involved in the supply chain. In the event that a problem arises during a drug or drug supply, the blockchain may be able to identify the last partner the item passed through. (iv) Effective recall management: The use of blockchain in a pharmaceutical store network can enable the identification of specific drug locations. Cluster updates can be transmitted or completed productively and quickly while maintaining patient health safety. A private blockchain can be a compelling case for using the pharmaceutical economic impact of the Coronavirus pandemic medicine industry inventory network, but the rights granted to each partner may differ depending on their business.
