Proper integrated scheduling of the handling equipment is crucial, especially in automated container terminals, where all the handling equipment is automated and must be coordinated to avoid interference. One of the most challenging problems both scholars and terminal operators face is introducing a proper scheduling plan for different equipment, considering the buffer capacity of dual-trolley quay cranes (QCs) and the limited storage locations of import containers. Methods: A mathematical model is proposed to integrate the scheduling of automated yard cranes and automated guided vehicles (AGVs), considering the limited buffer capacity beneath dual-trolley QCs and the storage allocation of import containers. Results: different instances were solved to evaluate the proposed model’s performance and investigate the...

However, since there is a lack in labor interference in the Automated Container Terminals (ACTs) as the equipment is controlled automatically, detailed scheduling and efficient planning of each piece of equipment is crucial to smoothly perform the various operations. Therefore, this paper proposes a Mixed Integer Programing model to consider the integrated schedule of Quay Cranes (QCs), Automated Guided Vehicles (AGVs) and Yard Cranes (YCs) to minimize the total waiting time of QCs and the number of needed AGVs, also the storage locations of import containers are determined.

Companies always trying to increase market share and profits by increasing customer satisfaction ... more Companies always trying to increase market share and profits by increasing customer satisfaction through the variety in the products they offer. However, at the same time, the Product variety brought many challenges to manufacturing systems and supply chains. Product variety could make a supply chain more exposed to various types of disruptions. There are always associated opportunity risks when variety products. Risk can be defined as the uncertainty of an event occurring that could have an impact on the achievement of the objectives. A natural extension of supply chain management is supply chain risk management. Risk management can't be done without define the risks then prioritize them to mitigate the most important risks. This paper helps in identifying and assessing the potential risks that are likely to disrupt a supply chain when variety products. All product variety risks gathered based on the previous researches of the effect of product variety on the supply chain from 1985 until 2014. The risks grouped under five basic dimensions of supply chain (Marketing, Logistic, Manufacturing, Engineering, and purchasing). Then the risks prioritized using Fuzzy Analytical Hierarchy process (FAHP).
