Abstract:
Analysing human specimens is necessary for doctors to diagnose their patients. In Thailand, to analyse the human specimens that are delivered to the Public Health Office requires some expensive medical appliances. Hence, they decided to deliver those human specimens to outer laboratories. The process of delivery sends their transport vehicle to take the human specimens from the Public Health Office to the dispersed outer laboratories. Because there is no standard criterion for the routes, it causes costly expenses and deferring time. In this study, the researcher showed an improved shipment for delivery of some human specimens using the Quick Solution Method, the simple method, and the Mathematical Model. By using the Traveling Salesman Problem to develop delivering system, the results showed both the Quick Solution Method and the Mathematical Model could discover five routes. The Quick Solution Method could reduce 39.09% of expenses and the Mathematical Model shorten the travel time by 39.54%, respectively. From the results, the Mathematical Model is the most suitable method to reduce costly expenses due to its method of ascertaining the best solution and augmenting the frequency of travel by adjusting the traveling time.
