A hospital's logistics operation and maintenance management system

1. Project Background

Large general hospitals consist of multiple building zones including outpatient buildings, inpatient buildings, medical technology buildings, underground parking lots and hyperbaric oxygen areas, with massive internal pipelines, medical supporting equipment and logistics facilities. Traditional logistics management faces multiple challenges: hard-to-inspect hidden pipelines, inefficient offline repair request circulation, isolated asset & maintenance data, lack of real-time energy consumption monitoring, and separated systems for campus security and logistics operation. This unified hospital logistics operation management platform is constructed with BIM digital twin as the visual foundation, connecting all businesses of logistics maintenance, equipment monitoring and security management, realizing one-screen overview of hospital-wide logistics resources and full-process online closed-loop management.

2. Platform Architecture & Four Core Subsystems

(1) Unified Login Portal

The platform home page adopts the 3D bird’s-eye digital model of the whole hospital as the login interface. A unified entry aggregates four business systems: Operation & Maintenance BIM System, Logistics Management System, Security Management BIM System and Work Order System. It supports switching between internal and external network environments, together with clock-in, account permission management and basic system configuration, realizing single sign-on and unified permission control across multiple systems.

(2) Operation & Maintenance BIM Visual System (Digital Twin Foundation)

A complete layered 3D BIM model of the whole hospital is built, displaying buildings by zones such as outpatient building, medical inpatient building, oncology building, parking lot and basement. It supports sectional viewing of building facades, indoor floors and underground electromechanical pipelines, with five built-in functional modules:

1. Pipeline Dashboard: Visually displays the distribution of hidden pipelines for water supply & drainage, HVAC, strong & weak electricity, enabling fast fault location.
2. Energy Management: Collects real-time water and electricity consumption data of the whole hospital, with zone-based statistics and trend analysis.
3. Equipment Monitoring: Binds air conditioners, water pumps, lighting and medical supporting equipment across the hospital, monitors real-time operation status and sends automatic alerts for abnormalities.
4. Medical Management: Connects medical supporting logistics facilities to manage oxygen supply, medical sewage and auxiliary diagnosis equipment.
5. Environmental Quality: Monitors indoor temperature, humidity, ventilation and air quality indicators of the hospital.

(3) Logistics Operation Management Business System

A standardized online backend covering full-process logistics businesses. The left menu covers all-scenario logistics functions:

• Maintenance & Upkeep Management: Work orders are categorized into Not Started, In Progress and Completed. Users can create new repair orders, manage fault types, search orders and export data, recording repair locations, equipment types and maintenance progress.
• Scheduling, Contract, File & Fixed Asset Management: Centralized management of logistics staff shifts, equipment maintenance contracts, equipment archives and hospital-wide fixed asset ledgers.
• Public Broadcasting, Uniform, Quotation, Inspection & Payment Application Management: Supports full-process online approval for logistics staff supplies, daily patrols, maintenance quotations and financial payment applications.

(4) Supporting Work Order System & Security Management BIM System

The work order system serves as a fast entry for repair submission, simplifying reporting procedures for medical and logistics staff. The Security Management BIM System carries campus security monitoring, patrol and hidden danger inspection businesses based on the 3D model, and shares data with logistics operation to realize integrated management of safety and logistics.

3. Core Project Value

1. Cost Reduction & Efficiency Improvement via BIM 3D Visualization: Digital twin replaces paper construction drawings. Hidden pipelines and equipment positions are clearly displayed, greatly shortening time for fault investigation and maintenance survey.
2. Full Online Closed-loop Logistics Workflow: Repair request, order dispatching, maintenance, acceptance and archiving are all processed online, eliminating offline paper documents and accelerating logistics response speed.
3. Refined Control of Hospital-wide Assets & Energy Consumption: Unified management of fixed assets and electromechanical equipment ledgers, real-time energy data monitoring to support energy-saving control and predictive equipment maintenance.
4. Integrated Multi-system Collaboration: Integrates operation visualization, logistics business and campus security, breaking data silos and allowing administrators to grasp the overall logistics operation of the whole hospital on one screen.
5. Customized for Medical Scenarios: Custom management modules for outpatient, inpatient, medical technology and special medical equipment, complying with special logistics management standards of medical institutions.
