Question

To design an optimum municipal solid waste collection route, which of the following is/are NOT desired:

Correct answer (C) Collection should occur in the uphill direction. Solution Heuristics for municipal solid waste collection route optimization include: Minimizing travel distance and time by avoiding redundant travel on the same street (Statement A is desired). Avoiding peak traffic hours on congested roads to reduce delays and fuel consumption (Statement B is desired). Designing routes such that collection occurs in a downhill direction to save fuel and reduce strain on the vehicle's engine and brakes. Therefore, uphill collection is NOT desired (Statement C is the correct answer). Locating the final collection point near the disposal site to minimize the 'deadhead' distance traveled by the loaded vehicle (Statement D is desired). Turn this into a strength.
