A decision-making approach based on Data Envelopment Analysis (DEA) for determining the efficient container handling processes (considering number of employed Automated Guided Vehicles (AGVs)) at a port terminal (PCT) is presented in this paper. Containers are unloaded from ship by quay cranes and transported to storage area AGVs. We defined performance measures proposed analysed effects when changing The values were collected and/or calculated simulation. Container process, with fixed...

Abstract In order for traffic authorities to attempt prevent drink driving, check truck weight limits, driver hours and service regulations, hazardous leaks from trucks, vehicle equipment safety, we need find answers the following questions: (a) What should be total number of inspection stations in network? (b) Where these facilities located? This paper develops a model determine locations uncapacitated network. We analyze two different formulations: single-objective optimization problem...

This paper presents a decision making approach based on Data Envelopment Analysis (DEA) for determining an efficient container handling strategy at automated port terminal. Containers are unloaded from the ship by quay cranes and transported to storage area Automated Guided Vehicles (AGVs). The objective of this is show how dispatching rules number employed AGVs affect measures effectiveness process compare their efficiencies using DEA. It was shown that simulation modeling efficiency...

AbstractDisruptions in carrying out planned bus schedules occur daily many public transit companies. Disturbances are often so large that it is necessary to perform re-planning of and crew activities. Dispatchers charge traffic operations must frequently find an answer the following question a very short period time: How should available buses be distributed among routes order minimize total passengers' waiting time on network? We propose model for assigning scheduled when there shortage...

The explosive growth of freight volumes has greatly increased the work seaports and urged port authorities to adopt advanced technologies cope with booming container ships. Linear motor conveyor systems (LMCS) automated guided vehicle (AGVS) are two candidate automation that can be used improve performance yard operations. In this paper, simulation models LMCS AGVS employed in marine terminals developed investigate effect different cargo handling technologies. Yard measures evaluated by...

With each day more present tendencies in business systems to focus on core processes, the position of transport activity and vehicle fleet within is imperatively examined: it an creating added value system or a mere unavoidable cost-maker. A decisive role attributed manner defining utilization way realization related activities. Therefore, link between based costing department (subsystem) has been presented this paper. This especially important public utility fleets. The legislation adopted...

Making decisions about dangerous goods positioning is crucial when it necessary to minimize environmental risks. In this paper, a specific problem of locating various kinds (with different characteristics) has been considered. Such should be located in known discrete set potential storage sites, under condition the minimum safety distance (MSD) between selected locations. The existence MSD consequence possibility that transfer their undesirable effects objects neighborhood. objective here...

In all transportation industries, when planned schedules are modified by delays, breakdowns or peaks of demand, ‘real‐time’ human decision making takes place. Dispatchers in charge traffic control usually allowed a very short time to make decisions that should mitigate the negative effects resulting from disturbance. This paper aims demonstrate feasibility dispatch support system could decrease work load for dispatcher and improve quality decisions. The proposed neural network, with ability...

Access density is a characteristic of two-lane highway sections whose role and significance in calculating the capacity level service Serbia has not yet been researched. Because large number access points per unit length (access density), direct applicability Highway Capacity Manual (HCM) methodology for highways called into question, as one influencing factors. In this case study, realistic vehicle speed data were tracked using global positioning system (GPS) device used to generate graph...

This study focused on vital resources at port container terminals such as quay cranes and dockworkers. We studied the impact of incorporating dockworker assignment problem (DWAP) into crane (QCAP). The aim this was to formulate solve an integrated model for QCAP DWAP, with objective minimizing total costs dockworkers, by optimizing workers’ assignment, so that ships’ due time spent in are not increased. proposed solution approach problem. Our has been validated adequate number instances...

This paper reviews the current state of ports on Serbian inland waterways with their main technicaltechnological characteristics.
