A multiperiod location-routing problem arising in the collection of Olive Oil Mill Wastewater
研究了橄榄油生产产生的废水（OMWW）的收集与运输问题，提出了一种自适应大邻域搜索元启发式算法，并在主要产油国的案例中验证了其经济可行性。
The process by which olive oil is produced yields two by-products, one of which is the brown-coloured Olive Oil Mill Wastewater (OMWW) and has no direct use. OMWW is generally disposed of into soil or rivers, potentially contaminating the environment. OMWW can be treated using ultrafiltration facilities, but this requires that OMWW is collected from oil mills and delivered to the treatment facilities using a fleet of vehicles in an economically viable manner. Such considerations give rise to a multiperiod location-routing problem. This paper formally introduces the problem and proposes an adaptive large neighbourhood search metaheuristic for its solution. The algorithm is applied on a case study drawn from one of the major olive oil producing countries. The paper presents computational and managerial results.
