So, the demand has to be filled with an efficient and optimized supply chain. Considering the importance of utilized communication tool between the blood donors, blood receivers, blood banks and blood donation campaigns organizers including the health services in Sri Lanka, a web based solution optimizing the blood donation chain was proceeded. In the system through the machine learning based implementations, all the users will be benefited to aware their eligibility on donating blood before a blood donation inputting their details while also get to know the upcoming monthly blood requirement of the country and get alerted on predicted requirements. Detection blood cells and analyze percentages is another function accomplished through the system along with a specified chat bot to assist the blood donors and campaign organizers for the blood donation process. The system's ultimate goal is to eliminate the time- consuming communication barrier by connecting the responding parties and facilitating awareness of the blood donation procedure.

INTRODUCTION Blood donation is a process of taking blood from a person voluntarily to be stored in a blood bank for later use in blood transfusions [14]. Many patients with a variety of medical issues can benefit from blood donations. Emphasizing the act of blood donation, World Health Organization highlight the fact that safe blood saves lives including women with complications during pregnancy and childbirth, children with severe anemia, often resulting from malaria or malnutrition, accident victims and surgical and cancer patients. Human blood is a necessary component of human existence for which there is no alternative.Blood cannot be appraised in term of cost, has a limited shelf-life, which must be utilized in a relatively short period [13]. Since that, a constant need of regular supply must be maintained. Sri Lanka annually collects more than 350,000 blood units. To supply the sufficient amount, it is important to make the services available easily, effectively and efficiently. The proposed solution is a comprehensive fully fledged system works on optimizing the blood donation chain. The blood donators will be registered to a system where they can be aware about the concerns of blood donating, and get notified in an emergency blood requirement, responding to the monthly blood requirements and aware about the nearby blood donations. The blood receivers will be ensured with the ability of requesting potential blood donors, locating the nearby places for blood transfusion, and viewing the current availability of blood on different blood banks. The benefactors who are willing to organize blood campaigns doesn‟t have to waste their time on seeking the potential places and resource suppliers. The proposed system will filter them the best locations to organize blood donation campaigns and recommend the responsible resource holders within a short time. Also, the system supposed to encourage all related parties of the system to enhance the blood donation via sending promoting messages and notifications, fulfilling the national cause of ensuring the sufficient, quality and adequacy blood supply to give the life to someone. 2. LITERATURE REVIEW Many studies have investigated people‟s attitudes toward blood donation.Even if the primary way tomeet blood requirement is to receive regular donations from healthy volunteers, unfortunately, only 5% of eligible donor population regularly donates [1]. Non-donors provide various reasons for never donating blood, such as lack of knowledge, fear of contracting the disease, insufficient time, not being asked, or being medically unfit [11]. If these non-donors can be assured that they are safe after a blood donation, whether they are eligible to donate blood, that blood donation is a less time-consuming process it will be a greater sustenance to strengthen the blood supply chain [12,13]. Currently, the blood bank's working process and storage system in Sri Lanka is mostly focused on documentations and files. Existing method of the blood donation camp organizing is selecting a date and place for the camp and contact the nearest blood bank. Then organizers should meet the relevant officers and make a request providing a letter. After that need to wait for their acceptance and recommendations. Also, they haven't a proper guidance and instructions system. If any person has a problem or question regarding the blood
