Deterministic waste-route optimization and compliance logging at municipal scale.
A working playbook for ops managers, logistics engineers, and Python automation builders. Constraint-hardened VRP solvers, IoT telemetry pipelines, and DOT/FMCSA-aware architectures — built to survive real fleets, real audits, and real field conditions.
Heuristic, stochastic VRP demos collapse the moment a municipal auditor asks for a reproducible trace. The reference architectures here treat determinism and constraint hardness as first-class engineering goals — not afterthoughts bolted onto a research prototype.
Routing matrices are constructed from validated telemetry, snapped to municipal right-of-way networks, and bound by regulatory windows before the solver ever runs. Every dispatch leaves a cryptographically signed audit record. Every fallback is a deliberate, declared state.
Python automation builders get production-shaped patterns: idempotent workers, structured logging, retry envelopes, schema-bound payloads, and explicit failure classifications. Nothing in here is a toy.
Use the sections below as a working reference — each one drills from architectural overview down to focused implementations: capacity limits, time windows, GPS polling cadence, bin sensor parsing, RBAC for ops dashboards, and more.
