Optimização do atendimendo domiciliar aos clientes da EDM: uma proposta baseada em WebSIG

Abstract

The Electricidade de Moçambique (EDM) plays a fundamental role in providing electricity at the national level and is responsible for ensuring an efficient and continuous service to its customers. However, EDM faces difficulties in accurately identifying the geographical location of customers’ residences, which results in increased waiting times for the resolution of technical faults and, consequently, customer dissatisfaction. Thus, the present study aims to develop a Web Geographic Information System (WebGIS) capable of supporting the household service process for technical faults. For this purpose, simulated data (customer names, meter numbers, mobile phone numbers and customer locations) based on patterns observed in the field were used to create the spatial database in PostgreSQL/PostGIS. The Dijkstra algorithm was implemented for optimised route calculation, and a web page was developed using Node.js 18+ for backend development and the Leaflet.js library for map visualisation, customer registration and management, and automatic route generation. The system allows for more accurate localisation of domestic customers through their meter numbers, enables efficient organisation of interventions, and supports the selection of shorter routes, significantly reducing the response time of field teams. The results demonstrate that integrating a WebGIS with routing functionalities is a viable and advantageous solution for EDM, contributing to improved customer service
