【正文】 e can specify that jobs bound for the same yard space are not unloaded from ships simultaneously, we cannot expect such containers to be unloaded at a time other than the allotted time interval, since a required resource to plete the job may bee unavailable after this time, as for example, if the yard crane bees unavailable. In view of the dynamically changing environment, a central control devises and maintains a job assignment plan that is periodically updated in order to coordinate operations, including crane scheduling. The system will allocate all jobs and resources periodically. In the port we studied, a job parcel can include a number of ships and a number of cranes together with jobs. Typically, there can be up to five ships with four to seven cranes per ship and a number of jobs depending on the size and configuration of ships. Jobs have a profit value assigned to the and resources, ., cranes, movers, lanes etc., are assigned to each of the jobs depending on their value to the overall operations plan which aims to optimize total throughput. When an assignment plan is updated, the central system reassesses the current state of operations to regroup and reassign job parcels. Because of this, time is acmodated by constant adjustments of job parcels and assignments based on the current state of all operations. Hence, once jobs and resources are assigned for the time period no update is necessary. 4 譯文 : 起重機(jī)調(diào)度與空間限制 Andrew Lim, Brian Rodrigues, Fei Xiao, and Yi Zhu 摘要 在這篇文章中，我們審視港口起重機(jī)調(diào)度空間和分離的制約因素。盡管對(duì)大部分分的港口業(yè)務(wù)來(lái)說(shuō)，這些制約因素沒(méi)有得到相應(yīng)的研究。實(shí)驗(yàn)顯示與啟發(fā)式的良好發(fā)現(xiàn)相比，在小規(guī)模情況下的最優(yōu)解決方案中，車輪優(yōu)化與本地搜索的做法在短期內(nèi)給予了良好的效果。 起重機(jī)調(diào)度和工作時(shí)間在港口管理中是至關(guān)重要的，因?yàn)槠鹬貦C(jī)在任何港口都處于土地和水路段的界面之間，每個(gè)國(guó)家也都有他自己的行車線，交叉口，以及車輛流量控制系統(tǒng)。交通及車輛的流量調(diào)度陸上口岸也有充分的研究。這構(gòu)成了一種“開放店” 平行 和同行機(jī)的問(wèn)題，當(dāng)工作包含獨(dú)立、單階段和預(yù)選任務(wù)的時(shí)候。這些制約因素影響 5 起重機(jī)的工作調(diào)度并且必須在業(yè) 務(wù)模型因素中加以考慮。 我們發(fā)現(xiàn)，港務(wù)集團(tuán)在運(yùn)籌決策時(shí)主要是依據(jù)經(jīng)驗(yàn)和仿真技術(shù)的。 問(wèn)題描述 在船舶靠泊的時(shí)間里，各種深紅或武裝卸設(shè)備用來(lái)寫下的貨物中，大部分是以集裝箱的形式卸下的?！柏浳铩痹谶@里包括集裝箱的能力各不相同，其中，無(wú)論是在船上或者是在碼頭，都分到固定的地方運(yùn)行起重機(jī)。在進(jìn)行集裝箱的運(yùn)送中，測(cè)序是關(guān)鍵性的，因?yàn)榧b箱存放在堆棧，船方和貨場(chǎng)以及在某些時(shí)候可指定特定專
