講座內(nèi)容簡(jiǎn)介:

Spatial optimisation models have been widely used to support locational decision making of public service systems (e.g. hospitals, fire stations), such as selecting the optimal locations to maximise the coverage. These service systems are generally the product of long-term evolution, and there usually are existing facilities in the system. These existing facilities should not be neglected or relocated without careful consideration as they have financial or management implications, which leads to multiple and potentially conflicting objectives in spatial optimisation models. In this seminar, I will talk about a spatial planning problem where two objectives are involved, including the minimum number of sites needed and the least relocation of existing facilities. I will discuss the model formulation and three solution approaches, using two case studies of optimising the retail stores and the large-scale COVID-19 vaccination network in England.

"空間優(yōu)化模型被廣泛用于支持公共服務(wù)系統(tǒng)的選址決策(如醫(yī)院、消防站),例如選擇最優(yōu)位置以最大化覆蓋范圍。這些服務(wù)系統(tǒng)通常是長(zhǎng)期演變的產(chǎn)物,系統(tǒng)中通常存在著現(xiàn)有設(shè)施。這些現(xiàn)有設(shè)施不應(yīng)輕率忽視或搬遷,因?yàn)樗鼈兩婕柏?cái)務(wù)或管理方面的影響,從而導(dǎo)致空間優(yōu)化模型中存在多個(gè)潛在沖突的目標(biāo)。在這次研討會(huì)中,我將探討一個(gè)涉及兩個(gè)目標(biāo)的空間規(guī)劃問(wèn)題,包括所需最小場(chǎng)地?cái)?shù)量和現(xiàn)有設(shè)施最小搬遷。我將討論模型的構(gòu)建以及三種解決方法,使用英格蘭零售商店和大規(guī)模COVID-19疫苗接種網(wǎng)絡(luò)的兩個(gè)案例研究。"
