Compute door-to-door work windows
See this course’s project requirements
A tested two-worker dispatch plan using supplied travel times, skill matches, appointment windows and breaks, plus a disruption revision and customer-update log.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Build a constraint matrix before allocating routes; include the original-case decision evidence and a separate changed-case result.
- Add J3 and return travel for full route end; include the original-case decision evidence and a separate changed-case result.
- Save the paired assignment with all checks visible; include the original-case decision evidence and a separate changed-case result.
- Recommend from comparable evidence and note the 10-minute assumption gap; include the original-case decision evidence and a separate changed-case result.
- Draft a revised dispatch/customer update with the changed times; include the original-case decision evidence and a separate changed-case result.
- Assemble dispatch packet and next verification action; include the original-case decision evidence and a separate changed-case result.
Review and revise
Use these criteria to check your work and choose what to improve.
- The final packet uses the supplied task-specific constraints and all six records agree.
- Every result can be traced to an identifier, input, calculation or stated decision rule.
- Changed-case practice updates dependent records and keeps holds or uncertainty visible.
- The packet states the learner role, authority boundary and specific next verification needed before real work.

The idea in everyday life
Original fictional workplace practice; paper or a local document is sufficient. The rules and records below are supplied for this exercise, not asserted universal workplace policy. Oak depot D→A20 min, A→C15 min, C→D25 min. M departs D09:00, does J1 at A40 min, then J3 at C40 min access starts 10:00. No other delays; write assumed times explicitly.
A route accumulates travel, service time and waiting; using only on-site minutes understates the time commitment.
Compute door-to-door work windows — worked practice
A route accumulates travel, service time and waiting; using only on-site minutes understates the time commitment.
Oak depot D→A20 min, A→C15 min, C→D25 min. M departs D09:00, does J1 at A40 min, then J3 at C40 min access starts 10:00. No other delays; write assumed times explicitly. Use paper or a local document. Preserve the original case and make a separate changed-case record.
1. Step 1
Add outbound travel to departure time.
You should see: Arrive A09:20.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
2. Step 2
Add J1 service duration.
You should see: Finish A10:00.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
3. Step 3
Add A→C travel and check access start.
You should see: Arrive C10:15; access already open.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
4. Step 4
Add J3 and return travel for full route end.
You should see: J3 finish 10:55; depot return 11:20; 140 minutes door to-door.
Keep the stated identifier, unit and policy alongside this result so another reader can check it.
What to finish
Add J3 and return travel for full route end; include the original-case decision evidence and a separate changed-case result.
Watch for this
Ignoring return travel or using a service minutes total as door-to-door capacity.
How can I tell I understand it?
Using the supplied identifiers, I can add J3 and return travel for full route end. My changed-case record names the revised condition and explains which dependent decision it changes.
