摘要: 在社会、经济的转型之下,依据行政院经济建设委员会人力规划处2004年的推估,台湾地区的老年人口比率将于2018年达到14%,而迈入“高龄社会”(Aged society)。在老年人口增加之下,高龄者住宅餐点配送服务(Home meal delivery)可以提供餐点给予行动不便以及独居无人照顾之高龄者。而在需求逐渐产生之下,高龄者住宅餐点配送之相关路径规划就显得相当重要。

对于餐点与食品的配送,跟一般物流配送有些许不同。配送过程中,通常旅行时间不能过长,以确保食物运送到高龄者时是新鲜的,而对于住宅餐点配送具有短时间、密集运送等特性。高龄者餐点配送须多加考虑服务高龄者之时间,有协助用餐用药之问题;配送路线主要位于城市当中,路径通常较短,配送时间处于用餐时段,受到城市内交通拥塞,旅行时间受到尖离峰影响,对于路径规划之旅行时间造成了许多不确定性。高龄者有不同用餐时间之需求,而尖峰时段造成路径规划之不准确,降低了配送服务品质。

本研究根据上述要件,建立数学模型,同时考量到拥塞以及软性时窗规划,并建立范例求解,产生出一组合适之路径规划解,验证模式之合理性,并测试改变参数对于模型之影响。藉由本研究,相关营运者可参考现况国外高龄者餐点配送做法以及较准确之路径规划,来提升服务品质并节省成本。
In the transformation of the social and economic, according to the Manpower Planning Department in Council for Economic Planning and Development in 2004 to the estimates of Taiwan’s elderly population ratio will be 14% in 2018, and then entered the “Aging Society”. Under the increase of elderly population, home-meal delivery of elderly can provide meal for disable or solitary elder. As the demand of home-meal delivery increase, the routing problem has become more and more important.

Delivery of meals or food is slightly different to the general distribution. In the distribution process, travel time cannot be too long to ensure food is fresh. For the home-meal delivery characteristics of short-term, intensive, and moreover, consider service time for the assistance of dining and medication to the elderly. Delivery route is mainly located in the city, the path is usually in short delivery time. Deliver time is in the dining period, the traffic is congestion, and travel time is influence by the peak and off-peak hours that caused many uncertainties. The elderly have different dining time demand, and the peak hours causing inaccurate path planning reduce the quality of delivery service.

Base on the above, this study develop the mathematical model which consider the congestion and the soft time window planning, and create a sample. The study produce a suitable path planning solution, verify the rationality of the model, and test the changes of each cost in the model. Through this study, the relevant operators can refer the current status of foreign home-meal delivery and the more accurate routing planning, to improve service quality and cost savings.
