Inbound Supply Chain Logistics Minimize the cost of an Inbound Supply Chain Logistics Industry problem

  • On the basis of shipment frequency (once a week/multiple times a week)
  • Routing, and mode selection
  • Direct shipment
  • Milk-runs
  • Hub & spoke model

Optimize Inventory & Transportation Costs

  • The optimized Supply Chain mainly juggles between two factors
  • Inventory costs
  • Transportation costs
  • The balance should be maintained between both the cost factors

More Transportation Cost High Frequency of Shipments Low Inventory Cost

The real success is to keep the Transportation cost low along with high frequency of Shipments

Selection of Distribution Mode

This is a direct encounter between Direct Shipment, Milk Run Shipment & Consolidated Hub Shipment

  • Truck Load ≥ 95%

Direct Shipment

  • Suppliers / Plants

are closer

  • Truck Load ≥ 85%

Milk Runs

  • Otherwise ---> Hubs *

If total time including hub is significantly greater than the total time between only supplier(s) & plant(s), then select Milk Runs

If multiple potential hubs, select the one that takes the least total time (not total distance)

Private Fleet Vs. Third Party Fleet Selection

Most of the Firms / Companies takes the decision about either to use its own private Fleet or to use the services of Third Party Logistics Providers for Transportation of Products / Goods Some of the criteria for decision making Private Fleet

  • Distribution centres / Retail

stores located in convenient areas (frequently visited areas)

  • Utilization of fleets with Full Truck

Load Third Party

  • Distribution centres / Retail

stores located in remote areas

  • Utilization of fleets with Less

than Full Truck Load Fluctuating Demand 50 – 75 trucks everyday Private Fleets (50 trucks) for certain Demand Third Party Fleets for fluctuating Demand

Real World Optimization Challenges

 Plant-Dock level restrictions: The number of docks of a plant, a truck can go to.  Inter & Intra country border restrictions.  Supplier time windows.  Department of Transportation restrictions.  Suppliers who prefer similar pick-up times.  Problem scale can range up to 1000+ suppliers, 50+ plants, and 5+ hubs.

Solution Approaches

To identify similar Supplier appointment time in the week during multiple visits

  • LP/MIP approach to combine Bin Packing & Vehicle

Routing Optimization

  • If large problem, LP/MIP approach can be carried out in

multiple iterations, each solving an MIP problem Multiple Travelling Salesman Problem Approaches Vehicle Routing Problem Bin Packing Problem Truck Routing via multiple Suppliers Loading of truck from Suppliers

Benefits  Total cost savings up to millions of dollars per year for large supply chains.  Big time savings & convenience during tactical planning than manual

  • r excel based approach.

 Planners can run multiple what-if scenarios.  Combination of Private fleet and Third Party fleet will give robustness to the Distribution system  Transportation costs can be kept low with high frequency of shipments by selecting the Distribution mode in an optimized way
