Adapt a method of solution in response to a change in the situation：練習問題

A local council has an existing model for waste collection, which optimises routes for 10 collection trucks to serve 5000 households over a 5-day week, aiming to minimise fuel consumption. The model assumes a fixed amount of waste per household.

A new government initiative mandates a separate weekly collection for organic waste, requiring each household to have two distinct collection bins (general and organic) and two separate collection passes per household, potentially on different days. The council cannot increase its fleet size of 10 trucks.

Which of the following is the most significant wider problem the council needs to consider when adjusting its waste collection model, beyond simply adding more routes?

A telecommunications company has a network optimisation model that balances bandwidth allocation, latency, and cost for its services. The model is based on expected data usage patterns and service level agreements (SLAs).

A global shift towards ubiquitous remote work and virtual reality applications significantly increases demand for high-bandwidth, low-latency connections in residential areas, particularly during what were previously off-peak hours. This usage pattern is highly variable and unpredictable.

When adjusting its network model, what is the most profound wider problem the company must address to adapt to this new reality, beyond simply upgrading infrastructure?

A national healthcare system uses a predictive model to forecast patient demand for various medical specialties, which aids in resource allocation (staffing, bed availability). The model is based on historical data, demographic trends, and seasonal variations.

A new, highly effective preventative vaccine is introduced for a common chronic illness that previously accounted for a significant portion of hospital admissions in one specialty. The vaccine is widely adopted by the population.

What is the most significant wider problem the healthcare system must consider when adjusting its predictive model for patient demand, beyond simply reducing the forecast for that specific illness?

A city council is modeling the environmental impact of replacing its entire diesel bus fleet with electric buses. The current model calculates the reduction in local tailpipe emissions and the total savings on fuel costs. Which of the following is the most significant wider problem that should be incorporated into the model to assess the true global sustainability of this change?

A company manufactures high-tech drones, with a production line optimised for a constant output of 100 units per day. The current model relies on a single, highly specialised supplier for a critical component, which accounts for $$ 30\% $$ of the total unit cost.

Due to recent geopolitical tensions, there is a significant risk of disruption to this supplier's operations. The company's management is considering adjusting its supply chain model. They identify a second potential supplier who can provide the component at a $$ 15\% $$ higher cost, but with guaranteed stability.

What is the most pressing wider problem the company needs to evaluate when deciding whether to integrate this second supplier, beyond a simple cost-benefit analysis of the component price difference?

A city council decides to replace all standard street lights with motion-sensor LED lights that only activate when a pedestrian or vehicle is detected nearby, aiming to reduce energy costs. Beyond immediate financial savings, what is a significant wider problem concerning public safety that the council must consider for pedestrians?
