在发展中国家，提供充分的初级卫生保健往往是一件麻烦事。问题是要提供足够数量的设施，以便在地理上可以进入，但又不足以适当地储存和配备人员。在许多较不发达国家，由于雨季漫长，只能在铺好的道路上旅行，交通问题更加严重。使用覆盖旅游模式，我们调查使用移动的设施，以解决这个困境，在苏胡姆区，加纳。该模型最大限度地减少了一个移动的设施的旅行，同时服务于一个可行的停止范围内的所有人口中心。计算结果表明，在雨季，该模型不能提供完全覆盖;超过6%的人口超过8公里的覆盖距离。在旱季，99%的人口可以在7公里的距离内获得旅游服务。超过四公里的距离，旱季问题成为医疗保健顾客和移动的设施之间的距离权衡。这些结果说明了移动的系统的灵活性的重要性：如果无法在所有季节提供无障碍环境，仍然可以在一年中的有利时间提供。
The provision of adequate primary health care in developing countries is often troublesome. The problem is to provide a sufficient number of facilities to be geographically accessible, yet few enough to be properly stocked and staffed. In many less developed countries accessibility problems are exacerbated by extensive rainy seasons in which travel is only possible on paved roads. Using the covering tour model we investigate the use of mobile facilities to resolve this dilemma in Suhum District, Ghana. The model minimizes a mobile facility's travel while serving all population centers within range of a feasible stop. Computational results show that in the rainy season the model cannot provide full coverage; over six percent of the population is beyond a covering distance of eight kilometers. In the dry season, 99 percent of the population can be served by a tour at a covering distance of seven kilometers. Beyond a distance of four kilometers, the dry season problem becomes a trade-off between the distance traveled by healthcare patrons and mobile facilities. These results illustrate the importance of flexibility of mobile systems: if accessibility cannot be provided in all seasons it may still be provided at favorable times of the year.
