Desarrollo de una aplicación web y móvil para el control de inventario en las ambulancias de la cruz roja del cantón Santo Domingo mediante el uso del código QR.

Abstract

The objective of this curriculum integration work was the development of an inventory control system for the ambulances of the Red Cross of the Santo Domingo city, utilizing innovative techniques that facilitate the management of information such as the use of QR codes. We carried out a study of the current inventory process, where 4 sub-processes were identified: ambulance registration, product registration, staff registration, inventory control and inventory verification. We established three phases for the development of the product: analysis, design, and development of the solution. The solution analysis phase was carried out through interviews to learn about the process and determine a feasible solution. Then, we designed the solution by developing a diagram showing the flow of inventory control information. In the development of the solution, we utilized the agile Scrum methodology, where 9 sprint were developed, each of these with a duration of 80 hours, the project was developed in the Dart programming language with the Flutter framework. The efficiency of the system was evaluated based on the ISO/IEC 25010 standard, in which the efficiency of the current and automated process was measured based on three indicators: response time, CPU usage and RAM usage. The analysis determined that the system helps improve the current process by 89.78% in terms of response time, resulting in an overall system efficiency rating of 95%. It was concluded that it is necessary to implement the system developed to avoid possible catastrophic accidents in the emergency area, keeping the ambulances properly equipped for any situation. It is recommended providing training to the staff so that they are familiar with the correct use of the system.
