Method & Evidence

AimHow can a generalized vehicle routing problem formulation be used to optimize short-term distribution operations in multi-echelon, multi-product supply chains to minimize total transportation costs?
MethodMathematical Optimization (Mixed-Integer Linear Programming)
ProcedureDeveloped and applied a Mixed-Integer Linear Programming (MILP) mathematical formulation for a generalized Vehicle Routing Problem in Supply Chain Management (VRP-SCM). This model accounts for multiple events at each location, multiple tours per route, and integrates customer allocation and shipment quantity decisions. The formulation uses a continuous-time representation and precedence constraints to sequence vehicle stops.
ContextChemical supply chains, logistics planning for manufacturing firms

Variables

IVSupply chain network structure (number of locations, products, depots, vehicles), demand at customer locations, operational constraints.
DVTotal transportation cost, vehicle route efficiency, delivery schedule adherence.
CVProduct types, vehicle capacities, operating costs per mile/hour, time windows (if specified).

Strengths & Limitations

Strengths

  • +Addresses a generalized version of the VRP, making it more applicable to real-world scenarios.
  • +Provides optimal solutions for complex problems in short CPU times.

Limitations

The complexity of real-world supply chains can be immense, and simplified models may not capture all nuances, such as traffic congestion, driver availability, or unexpected disruptions.

Reliability & validity

The study's validity is supported by its ability to solve complex problems to optimality and its comparison to existing VRP and PDP models. Reliability is suggested by the consistent achievement of optimal solutions within short CPU times for tested examples.

Think critically

How might the 'multiple events at every location' and 'multiple tours per route' features of the VRP-SCM model be practically implemented in a physical distribution system, and what are the potential operational challenges?
