UNSTRUCTURED The article investigates policies for helping emergency-centre authorities for dispatching resources aimed at reducing goals such as response time, the number of unattended calls, the attending of priority calls, and the cost of displacement of vehicles. Pareto Set is shown to be the appropriated way to support the representation of policies of dispatch since it naturally fits the challenges of multi-objective optimization. By means of the concept of Pareto dominance a set with objectives may be ordered in a way that guides the dispatch of resources. Instead of manually trying to identify the best dispatching strategy, a multi-objective evolutionary algorithm coupled with an Emergency Call Simulator uncovers automatically the best approximation of the optimal Pareto Set that would be the responsible for indicating the importance of each objective and consequently the order of attendance of the calls. The scenario of validation is a big metropolis in Brazil using one-year of real data from 911 calls. Comparisons with traditional policies proposed in the literature are done as well as other innovative policies inspired from different domains as computer science and operational research. The results show that strategy of ranking the calls from a Pareto Set discovered by the evolutionary method is a good option because it has the second best (lowest) waiting time, serves almost 100% of priority calls, is the second most economical, and is the second in attendance of calls. That is to say, it is a strategy in which the four dimensions are considered without major impairment to any of them.

The Relationship

This paper explores the issues of representativeness and participation in the collective processes involved in the elaboration of the geographical indications (GI) specifications and the governance of the GI initiatives. The objective is to understand the relationship among collective dynamics, representativeness of relevant stakeholders, and the legal frameworks for the protection of GIs. Using a qualitative methodology based on an analysis of six case studies in France and Vietnam, we show the role of the law in shaping the different ways of understanding and implementing the concept of representativeness in the French producer-led and the Vietnamese state-driven approaches to GI protection. In France, the GI specifications result from negotiations among all legitimate stakeholders, which may prove long, complex, and lead to standards that can continue to be challenged after the GI registration. We also argue that the rules for the representation of all GI users in the decision-making processes do not necessarily lead to fairness. In Vietnam, local stakeholders usually have a consultative role under the authority of the State, resulting in their little understanding and low use of the GI. Their empowerment is further hindered by the involvement of state authorities in the management of the producers’ associations. We conclude by discussing in-between solutions to promote the producers’ representation and participation.
