AI roster generator for hospital departments

An AI roster generator takes a department’s rules, patterns, staff availability and preferences and produces a complete roster in minutes, scoring thousands of candidate rosters and returning the one that best satisfies everything at once. HosPortal’s AI builder does this for hospital medical departments, and it is an optional module at A$7 per user per month, billed annually (A$80 per user per year), on top of the Standard plan. Royal Hobart Hospital’s anaesthesia department cut roster building from four days to five hours with it.

What the AI actually does

HosPortal’s roster AI is a constraint solver, not a chatbot. You give it the shifts to fill, the people, the hard rules (award hours, rest periods, skills, supervision) and the soft goals (preferences, fairness counters, pattern continuity), and you weight the soft goals. It tries thousands of combinations per second, scores each against your weights, and returns the highest-scoring roster as a draft. You review the statistics, adjust weights or fix individual shifts, and publish. Because the rules are yours and visible, the result is explainable to the person who asks why they got Saturday night.

What it needs from you

  • A roster structure: shift templates or a repeating pattern over your cycle length.
  • Your rules: Work Rules, Shift Conflict Rules, supervision rules and skill requirements, which you set up once and reuse.
  • Availability: leave, block-outs and preferences gathered through self-roster windows.
  • Priorities: how much weight to give preferences versus fairness versus pattern continuity.

Where it fits

  • Whole-roster builds for anaesthesia, ED, ICU and medicine departments each period.
  • Term rosters for junior doctors, generated per term from the term’s pattern.
  • Filling what self-rostering leaves after a preference or selection round.
  • Re-solving when a block of leave or a resignation breaks a published roster.

HosPortal also has a conversational AI assistant for administrators and a standard MCP connector so external assistants such as Claude or ChatGPT can query rosters, leave and staff data. See the AI features page and pricing.

Frequently asked questions

What is an AI roster generator?

Software that builds a complete roster automatically from a department’s rules, patterns, availability and preferences by scoring many candidate rosters and returning the best. HosPortal’s version is built for hospital medical departments.

Is HosPortal’s roster AI a large language model?

No. Roster building uses a constraint-solving optimiser that applies the rules you define; results are deterministic and explainable. HosPortal’s separate AI assistant, which answers administrators’ questions, does use a language model.

How long does an AI roster build take?

Typically minutes for a departmental roster period; the time rises with the number of staff, shifts and rules. The draft is then reviewed before publishing.

How much does the AI module cost?

A$7 per user per month, billed annually (A$80 per user per year), added to the Standard plan of A$17 per user per month (A$200 per user per year). All plans support it, so it can be switched on when the department is ready.
