Final answer:
Utilizing supply chain planning systems increases productivity and variety of goods while lowering prices to consumers and enables cost-effective transportation.
Step-by-step explanation:
The utilization of supply chain planning systems can bring about three broad benefits. Firstly, they can increase productivity by streamlining processes and improving coordination among the various parts of the supply chain. This leads to more refined products and efficient operations. Secondly, such systems generally lead to a wider variety of goods available to consumers at lower prices, due to improved efficiencies and economies of scale. Lastly, optimized supply chain planning can result in cost-effective transportation, as it enables better use of resources and infrastructure, such as uncrowded freeways and alternative transport options, thus reducing transit times and costs.
