Optimization & Decision Systems

Simulation, Optimization & Planning

Shifts, resources, constraints. A problem that grows exponentially. We solve it.

Planning team shifts is not a simple problem. It is a combinatorial problem: every variable added — a legal constraint, a preference, an absence — exponentially multiplies the number of possible combinations. Doing it manually means hours of work, errors, conflicts and suboptimal solutions. Doing it well, at scale, is beyond human capability.

We build automatic optimization systems that handle complex constraints, respect rules and people, and produce optimal operational plans in times a human could never achieve.

Simulation, Optimization & Planning

Problems we solve

Blocked knowledge, critical dependencies and inefficiencies holding back growth

Slow and inefficient manual planning

Building a shift plan takes hours, sometimes days. And often the result is not even optimal.

01

Legal constraints that are difficult to manage

Collective agreements, labor regulations, maximum hours, mandatory rest periods: every rule is a constraint the planner must keep in mind.

02

Individual preferences ignored

Workers have different needs. Ignoring them costs in terms of satisfaction, turnover and productivity.

03

Impossible scalability

As the team and constraints grow, problem complexity increases exponentially. Manual planning does not scale.

04

Costly errors

An uncovered shift in a critical department, a violated constraint, insufficient coverage.

05

Use Cases

Real projects, measurable results

Healthcare sector — Automatic shift generation

Hospitals and healthcare facilities manage large teams, 24/7 shifts, strict regulations, and individual worker preferences. We developed an optimization system that automatically generates shifts taking into account all legal and contractual constraints, individual operator preferences, and the coverage needed for each department.

A problem of exponential complexity, solved automatically and repeatably.

Technology Corner

The architecture and technologies that make the difference

Our projects don't rely on off-the-shelf solutions. Every system is designed on the right architecture for the specific problem — and the technology choice makes the difference between a tool that works in demo and one that holds up in production.
