【摘要】：隨著集裝箱碼頭吞吐量的持續(xù)增長和船舶的不斷大型化,閘口通過能力與貨物運(yùn)輸需求不匹配已成為集裝箱碼頭發(fā)展的瓶頸,閘口擁堵成為部分集裝箱碼頭的常態(tài)化問題。如何科學(xué)合理地規(guī)劃閘口的通道數(shù)量,協(xié)調(diào)好閘口通道數(shù)與集卡到達(dá)率、閘口服務(wù)率、故障率和修復(fù)率的關(guān)系,是提高碼頭運(yùn)輸服務(wù)水平、保障港口發(fā)展空間的關(guān)鍵。本研究在綜合分析集裝箱碼頭閘口系統(tǒng)作業(yè)特征的基礎(chǔ)上,應(yīng)用可修排隊(duì)系統(tǒng)理論,建立閘口處車輛平均排隊(duì)長度、平均故障通道數(shù)與集卡到達(dá)率、閘口服務(wù)率、閘口故障率和修復(fù)率的關(guān)系。根據(jù)碼頭閘口和集卡的能耗,將閘口作業(yè)系統(tǒng)的碳排放進(jìn)行量化。在此基礎(chǔ)上,分析集裝箱碼頭閘口工作時(shí)的運(yùn)營成本、故障時(shí)的維修成本,集卡排隊(duì)的時(shí)間成本、燃油成本,以及閘口作業(yè)系統(tǒng)的碳排放成本,以計(jì)算期內(nèi)閘口作業(yè)系統(tǒng)總成本最小為目標(biāo),以可修排隊(duì)系統(tǒng)的穩(wěn)態(tài)平衡條件為約束,構(gòu)建考慮碳排放的集裝箱碼頭閘口優(yōu)化模型。最后,以某集裝箱碼頭為例,計(jì)算不同集卡到達(dá)率下的最優(yōu)進(jìn)港閘口通道數(shù),并對(duì)模型參數(shù)進(jìn)行影響分析。研究結(jié)果表明：碳排放成本與總成本的量級(jí)相差較大,但存在最優(yōu)的閘口通道數(shù),使碳排放成本與總成本同時(shí)達(dá)到最�。患ǖ竭_(dá)率、閘口服務(wù)率、故障率、維修率在一定區(qū)間內(nèi)變化時(shí),閘口系統(tǒng)的最優(yōu)閘口通道數(shù)不變；集卡到達(dá)率對(duì)最優(yōu)閘口通道數(shù)的影響比較穩(wěn)定,閘口服務(wù)率越小,其對(duì)最優(yōu)閘口通道數(shù)的影響越顯著,閘口修復(fù)率對(duì)最優(yōu)閘口通道數(shù)的影響比故障率的影響更為顯著。
[Abstract]:With the continuous growth of container terminal throughput and the continuous large-scale of ships, the mismatch between gate passing capacity and cargo transportation demand has become the bottleneck of container terminal development, and gate congestion has become the norm of some container terminals. How to plan the number of gate channels scientifically and reasonably and coordinate the relationship between the number of gate channels and the arrival rate of collection card, gate service rate, failure rate and repair rate is the key to improve the level of wharf transportation service and ensure the development space of port. Based on the comprehensive analysis of the operation characteristics of container terminal gate system, this paper applies the theory of repairable queuing system to establish the average queue length of vehicles at the gate, the average number of fault channels, the arrival rate of collection card and the service rate of gate. The relationship between gate failure rate and repair rate. According to the energy consumption of gate and collector, the carbon emission of gate operation system is quantified. On this basis, the operating cost of container terminal gate, the maintenance cost in the event of failure, the time cost of card queue, the fuel cost and the carbon emission cost of gate operation system are analyzed. In order to minimize the total cost of gate operation system during the calculation period and constrained by the steady state balance condition of repairable queuing system, a container terminal gate optimization model considering carbon emission is constructed. Finally, taking a container terminal as an example, the optimal number of entrance gate channels under different card arrival rates is calculated, and the influence of the model parameters is analyzed. The results show that the order of magnitude of carbon emission cost is quite different from that of total cost, but there is an optimal number of gate channels, which minimizes the cost of carbon emission and the total cost at the same time. When the arrival rate of the collection card, the service rate of the gate, the failure rate and the maintenance rate change in a certain range, the optimal number of gate channels of the gate system remains unchanged. The influence of the arrival rate of the collector card on the optimal number of gate channels is stable, and the smaller the gate service rate is, the more significant the influence on the optimal number of gate channels is, and the influence of the gate repair rate on the optimal number of gate channels is more significant than that of the failure rate.
