A Successful Implementation of Locating Passive Cooling Facilities: The Case of Northern Thailand
报告了泰国北部自1985年以来的被动冷却项目中的设施选址与分配实施，通过离散选址分配模型为农产品采后处理链中的冷却设施提供最优布局决策支持。
This paper reports the actual implementation of a location-allocation study, which is one aspect of the overall Passive Cooling (Thailand) Project conducted in Northern Thailand since 1985. The goal has been to generate decision supports for ‘optimal’ placements of cooling facilities and the assignment of sites to these facilities as part of the post-harvest handling-chain operation of agricultural products. The basic questions addressed in this work are the issues of how many facilities to set up and where to locate them for maximum utility. Our selected approach is to use discrete location-allocation modelling, as, among other reasons, the problem at hand has a most natural network setting. Direct methods as well as efficient heuristics are examined, and sample numerical results are reported as illustrations of the continual implementation.
