How Alibaba Digitally Managed 100,000 Employees’ Return to the Office

1. Big‑Data Entry Control

Employees must present an "Alibaba Campus Pass" generated by the internally built "Dianzuo" system, which aggregates health‑check data, campus quotas, and other dimensions to produce a green, yellow, red, or gray QR code. Only a green code unlocks the gate, linking directly with the access‑control system.

The system integrates health‑check records, door‑access, notification, and master‑data services, matching daily staffing needs with workspace allocation, issuing green codes and access rights automatically. Administrators can adjust campus quotas in real time, trigger reminders for eligible but absent staff, and iterate the policy twice daily as pandemic conditions evolve.

A data dashboard presents real‑time metrics to the epidemic command center, department leads, and HR, supporting rapid decision‑making.

2. Smart Robot Meal Reminders

To avoid crowding in cafeterias, an AI‑powered robot ("Nei‑wai Xiao‑Mi") sends personalized meal‑time and location notifications based on each employee’s entry schedule and workstation distribution.

The backend calculates staggered dining slots for each campus, currently serving 16 locations and helping tens of thousands of staff eat on time, reducing peak traffic by over 80%.

The system also forecasts restaurant attendance, duration, and five‑minute flow, enabling precise catering and staffing while minimizing food waste.

3. Predictive Parking Management

Alibaba’s "Smart Parking" app lets employees reserve temporary spots in four major campuses. The platform matches authorized staff with available spaces, predicts daily vacant slots, and pushes reservation offers to those lacking parking.

This data‑driven approach improves overall parking utilization across campuses.

4. AI‑Based Mask‑less Detection

The "Wei‑Tuo" system uses computer‑vision algorithms to identify individuals without masks in public areas, achieving over 95% accuracy and sending alerts to security teams.

Detection data feeds a real‑time dashboard for safety monitoring and has been deployed in more than 200 Hema stores nationwide.

5. Campus Environment Intelligent Control

The environment control platform adjusts fresh‑air and HVAC systems to keep indoor temperature between 20‑22 °C, provides negative‑pressure ventilation, and aggregates sensor data for rapid response.

Heat‑map visualizations display crowd density, helping administrators prevent overcrowding.

6. Contact‑less Self‑Service

Employees can query pandemic‑related campus policies and submit disinfection or other service requests via the "Nei‑wai Xiao‑Mi" robot or the "Code‑on‑Admin" portal, receiving assistance without physical contact.

These digital upgrades have created a new paradigm for administrative decision‑making, offering robust data‑backed insights for safety and efficiency.
