Pharmaceutical routing

Delivery visit sequences were recalculated on historical orders while preserving the driver territories that defined the comparison.

Industry: Pharmaceutical distribution
Decision family: Sequence optimization
Evaluation scope: Historical-order validation

Customer identity and identifying operational details are withheld.

The operating decision

A better delivery sequence must be found without changing the territories that drivers already serve.

Inputs: Historical delivery orders · Driver territories · Delivery locations
Decision: Visit order within each territory · Fixed optimized order versus daily recalculation
Constraints: Existing driver territories · Comparable territory data

How it is approached

Keep the operating scope comparable
Retain the same driver territories and compare only territories whose data remained consistent.
Change the visit order
Recalculate the order in which each driver visits delivery locations, using the historical orders in that territory.
Compare fixed and daily plans
Evaluate the baseline, one fixed optimized order and an order recalculated for each day on the same historical basis.

Compare the visit order on the same historical orders.

Route-planning comparison

Historical orders · same driver territories

Existing routes

Optimized order, fixed

Re-optimized daily

Original historical-order comparison, with driver territories held fixed. The bar proportions are preserved; this is a recalculation study, not distance savings realized in operation.

Historical-order validation

Validation & scope

The source compares route recalculations on historical orders. It does not establish distance or cost savings realized in operation, and its separate route illustration is not the same evidence as the order-data evaluation.
