As the competitive environment changes the way companies do business, transportation managers are embracing lean principles mixed with tactical planning software to support cost reductions and quality improvements. Applying lean initiatives to supply chain and logistics operations is one method that allows businesses to reduce cost, but the marriage of tactical planning software with lean principles introduces a new approach and additional opportunity to eliminate waste.
Lean is a team-based form of continuous improvement that focuses on identifying and eliminating waste and increase of speed and flow of an operation, such as distribution of products. Waste can be defined as activities that do not add value for the customer.
A short waste target list for a distribution transportation planner may include the following:
- Underutilizing employees or behavioral waste
For example, managing a large delivery fleet with a relatively fixed, repeating delivery pattern will benefit from an optimal territory planning and routing solution. Since lean adds emphasis on waste, non-value added work, queue times, to traditional process analysis, improving the distribution and routing plan for a company’s fleet can eliminate waste in all of the above categories.
Selecting strategic territory planning software that will optimally divide a customer region into geographical “territories” based on customer delivery requirements can be an important first step in the lean process. Think of each territory is a contiguous area containing the customers that will form a single route, or a regular pattern of routes, over a day, week, month or other time period. Lean solutions can include optimal delivery territories shaped to minimize total travel and to equalize the delivery workload for drivers.
Most software packages utilize geographical mapping software such as MapPoint or Google Maps to generate a solution that will minimizes total travel miles while meeting customer service and delivery requirements. Some of these tools can also be personalized and customized to meet specific business requirements. Planning tools that create both territories and routes in a single integrated package appear to be the most popular.
Before implementing the territory planning software solution, let’s compare the results to the target list of waste. Transportation waste is minimized. Drivers (“employees”) become more productive since they now have a delivery territory designed to adhere to the driver profile, which may specify shift time and driving break intervals. Routes are optimized, so there is no more wasted motion time. Routes can be built to ensure sufficient inventory is available at all stops. Natural boundaries such as rivers, mountains, canyons and man-made boundaries such as rail tracks, major highways, canals can be model to create optimal delivery territories that are bounded by these constraints, thereby eliminating driver waiting to go around these obstacles.
In summary, managers that use transportation routing and territory planning software are following the lean principles to identify and reduce waste. Implementing the solution can potentially reduce transportation costs by 5% to 20% by decreasing miles traveled and increasing on-time delivery while dramatically increasing driver productivity. Lean principles when married to tactical planning software can be competitive weapons and a great advantage in tough economic times. Start considering lean logistics principles in conjunction with territory planning software applied to distribution transportation problems as opportunities to reduce waste.
