VSEngineering Contradiction Analysis

1Use of energy by moving object

If existing vehicle dispatch plan creation methods are used, then the planning process is simple, but energy consumption and carbon dioxide emissions are not effectively reduced

Solution Approach 1:

The patent applies parameter changes by considering multiple variables including road slope, traffic conditions, vehicle load, and weather conditions to dynamically calculate evaluation indices. This transforms the dispatch planning from a static process to a dynamic one that adapts to changing parameters, thereby reducing energy consumption while managing complexity through systematic parameter integration.

Solution Approach 2:

The patent replaces traditional mechanical/manual dispatch planning methods with an automated calculation system that uses computers to evaluate multiple plan candidates based on predetermined indices. This substitution of mechanical processes with computational algorithms enables comprehensive energy optimization without proportionally increasing operational complexity.

The patent applies segmentation by dividing the evaluation process into distinct components: road condition evaluation, traffic condition evaluation, vehicle condition evaluation, and weather condition evaluation. Each factor is assessed separately using specific indices, and the results are aggregated to determine the overall optimal plan. This segmentation reduces calculation complexity by breaking down a complex problem into manageable, independent evaluation modules.

AI summary

In a vehicle dispatch plan creating system, a calculator calculates, for each plan candidate, a value of an evaluation index for each vehicle assuming that the corresponding vehicle travels in accordance with the corresponding plan candidate. The evaluation index for each vehicle includes at least one of:(i) an energy consumption of the corresponding vehicle;(ii) a quantity of carbon dioxide emissions from the corresponding vehicle; and(iii) a cost required for a travel of the corresponding vehicle.The calculator calculates, for each plan candidate, the sum of the values of the evaluation index for the respective vehicles as a value of a candidate evaluation index for the corresponding plan candidate. A determiner determines one of the plan candidates as a vehicle dispatch plan. The determined one of the plan candidates has the lowest value of the candidate evaluation index in all the plan candidates.
