Strong Tower Consulting: Intermodal Drayage and Port Logistics

Keep the container, chassis and appointment records separate

Strong Tower Consulting for intermodal drayage and port logistics focuses on the relationship between cargo availability, equipment custody and executable dispatch work. A container release, an appointment reservation and a chassis interchange establish different facts. The architecture should preserve each source record rather than forcing all three into one shipment status.

The work order references the container and its cargo movement. A chassis assignment records the equipment used for a defined interval. Terminal availability and release notices establish what the source reported at a particular time. This separation lets dispatch see that a container is available while an appointment or suitable chassis remains unresolved.

Store event time, receipt time, source reference and the version of any free-time rule. A changed notice must update the planning view without deleting the earlier evidence. Operators need to distinguish a revised source value from a data-entry correction and from an estimate generated by their own planning system.

Model exposure before attempting automation

Free-time calculations depend on the terminal or equipment provider's rules, the relevant calendar, holds and effective dates. Do not use one universal last-free-day algorithm. The interactive example below deliberately begins after an authorized process has supplied elapsed and free days. It illustrates arithmetic exposure, not terminal billing authority.

Chargeable days equal the greater of zero or elapsed days minus free days. Estimated exposure equals chargeable days multiplied by the configured daily amount. Stepped tariffs require a different calculation. An estimated amount should remain separate from an accepted supplier invoice and from a customer-recoverable accessorial.

A dispute package should retain the availability notice, appointment history, pickup and return events, rule version and relevant communications. A current dashboard value is insufficient if the disputed decision occurred before the source corrected its record. Preserve what the dispatcher knew when the move was planned.

Use an exception queue with accountable release

Prioritize unresolved work by the approaching operational deadline and the completeness of required evidence. A missing release, unavailable appointment or unmatched return event needs a named owner. The queue should show the next action and the authoritative source to consult. It should not assign fabricated dates merely to make the board appear complete.

Recommended implementation artifacts include an equipment relationship model, calendar ownership register, terminal event mapping and reconciliation report. Integrations should support duplicate events, changed identifiers and late arrivals. A manually resolved hold needs a reason and supporting reference so subsequent automation does not reopen or incorrectly clear it.

Acceptance scenarios for a drayage operating slice

Test a container whose availability changes after an appointment is reserved; a chassis substituted during the move; a return reported after the billing cutoff; and a free-time rule with a calendar exception. Replaying the same event should not create another equipment interval or duplicate an accessorial candidate.

Require dispatch and accounting to review the same movement history. The dispatch view needs executable work and deadlines. Accounting needs source-backed eligibility and supplier reconciliation. Strong Tower Consulting's architecture engagement should leave both views connected to the same evidence, with explicit assumptions and no claim that a preliminary exposure estimate overrides the applicable agreement.
