|
## 1. Objetivo Técnico
|
|
|
|
Implementar el sistema de programación de obra con:
|
|
- Creación y gestión de cronogramas con dependencias entre actividades
|
|
- Cálculo automático de ruta crítica (Critical Path Method - CPM)
|
|
- Generación y seguimiento de Curva S (planificado vs ejecutado)
|
|
- Cálculo de indicadores EVM: SPI, CPI, EV, PV, AC
|
|
- Reprogramaciones con control de versiones
|
|
- Dashboard de seguimiento en tiempo real
|
|
|
|
---
|
|
|
|
## 2. Stack Tecnológico
|
|
|
|
### Backend
|
|
```typescript
|
|
- NestJS 10+
|
|
- TypeORM para PostgreSQL
|
|
- PostgreSQL 15+ (schema: schedules)
|
|
- node-cron para cálculos diarios
|
|
- EventEmitter2 para eventos
|
|
```
|
|
|
|
### Frontend
|
|
```typescript
|
|
- React 18 con TypeScript
|
|
- Zustand para state management
|
|
- Chart.js para Curva S y gráficas
|
|
- react-gantt-chart para diagramas de Gantt
|
|
- date-fns para manejo de fechas
|
|
```
|
|
|
|
### Análisis
|
|
```typescript
|
|
- Algoritmo CPM (Critical Path Method) en JavaScript
|
|
- Regresión lineal para proyecciones
|
|
- Análisis de varianzas y tendencias
|
|
```
