The Android-based employee delivery Viewer Application is a program provided for the convenience and accurate work flow of delivery personnel. It has an algorithm that automatically calculates the shortest distance for delivering items and the order of delivery. A day’s work starts by sending the customer an estimated time of delivery. After that, GPS is used to re-measure the anticipated delivery time every 5 minutes, updating the estimated delivery time on the customer’s app. The delivery personnel, when a delivery is completed, inputs the customer’s signature and presses the ‘complete’ button. This shows which areas have completed delivery by marking them in different colors, and then synchronizing this information with the customer system and work system. The delivery personnel can check the customers’ data with just one click and can take advantage of the function that allows one to send text messages or phone calls. Fig. 2 shows the UI configuration of the employee delivery viewer application.
