This paper focuses on the modeling and analysis of complex production systems such as Steelmaking Continuous Casting (SM-CC) plants. To this aim, the discrete event simulation is employed to verify the dynamics and the performance of the SM-CC systems. First, the manufacturing system activities are described in detail by the Unified Modeling Language (UML). Then, the UML activity diagrams are translated in a discrete event simulation model. Hence, a real system involving a SM-CC plant located in Italy is considered and analyzed. Some simulation results show that the proposed modeling and analysis approach can be effectively used to improve and assess the performance of the system.

This paper deals with the scheduling of operations in a Steelmaking and Continuous Casting (SM-CC) plant. In particular, we consider a real case study of an integrated plant located in the North of Italy. First, we describe in details the SM-CC process of the considered system by using the Unified Modeling Language. Second, we focus on the schedule of casts on the continuous casting machine that is subject to different types of setup operations. With the objective of minimizing the maximum completion time, the schedule of the continuous casting machine is modeled by a Mixed Integer Linear Programming formulation. An example enlightens how a proper scheduling of the casts is of basic importance to obtain good system performances.

Making Siliguri a Walkable City

Walkability provides a foundation for a sustainable city. The effectiveness of walkability is linked with socio- economic, environmental and psychological issues. Walkability provides safety, security and comfort for the city dwellers while traveling as well as cleanliness and transparence in mobility by reducing street congestion, street pollutions, vehicle fuel cost and road fatalities. Present motorization and urbanization in Indian cities, resulting in reduced mobility and increasing hazards, has thrown a challenge to the planners and decision makers in favor of conversion of motorized cities to walkable cities. In this paper, the prospects for walkability and related issues has been analyzed and discussed for Siliguri city. Siliguri, a medium sized city of West Bengal, India has emerged as a major urban center and acts as Gateway to the entire north-eastern states of India. Planners fear that the population of Siliguri may reach up to 2 million by 2025. As Siliguri is not a planned city, it has been experiencing problems in meeting present demand with its social and physical infrastructure. The streets of Siliguri is almost choked by mixed traffic, usually paratransits and personalized two/four wheelers, slow moving vans, dense urban corridors and existence of busy commercial set ups along major roads. The rapid motorization and increasing level of economic status of the city dwellers has put immense pressure on transportation system of the town resulting in high level of congestion and fatalities. Thus, keeping many aspects as constraints, there is an urgent need to identify the prospects of walkability in the city for sustenance. In this paper, an effort has been made to identify possibilities of transforming Siliguri into a walkable city where more people will opt for walking as their first choice for short trips and to make longer distance trips using a combination of walking and public transport instead of using personal automated vehicles. The research fi

In this paper we deal with the problem of modeling and simulating the Steelmaking and Continuous Casting (SM-CC) processes. The SM-CC production processes are very complex and exhibit production cycles that have to be managed with suitable sequencing and scheduling procedures in order to minimize blocking and bottleneck conditions. The paper describes in details the SM-CC process by a modular approach in a Timed Petri Net framework. In order to show that the modeling procedure is suitable to describe large systems, we model and simulate a real case study involving a SM-CC plant located in the North of Italy.

Dry magnetic separation of high-sulfur fine coal was carried out using a novel permanent magnet high-gradient magnetic separator (HGMS). The samples were analyzed using a vibrating sample magnetometer (VSM) and X-ray diffractometer (XRD) to determine the properties of the different size fractions of pulverized coal. It was found that magnetic susceptibility and the ash and sulfur content increased with increasing particle size below 0.9mm;Sulfur reduction of 44% and ash reduction of 43% were obtained from coal with particle size of 0.15∼0.074 mm, while the clean coal yield reached 95.61%. The results show that desulfurization efficiency and de-ashing efficiency decreased with increasing size of the pulverized fine coal from 53% to 37% and from 49% to 32%, respectively. Desulfurization efficiency and de-ashing efficiency of fine coal were significantly improved by permanent magnet dry magnetic separation using a new permanent magnet HGMS. However, decreases in desulfurization efficiency and de-ashing efficiency of the different size coal samples were found to correlate with reduced clean coal recovery, besides coal fraction sized at 0.0-0.074 mm. © 2013 IEEE.

This paper deals with the Steelmaking and Casting phases of a real integrated plant. We focus on the scheduling of the casts on the machines of the process and on the cranes that perform the internal transport. The casting phase is made by Continuous Casting and Ingot Casting machines. A Mixed Integer Linear Programming model is presented for the schedule of operations, with the objective of minimizing the makespan. The model is divided into four sub-models: the steelmaking and casting processes, the cranes, the continuous casting machines and the ingot casting machines. An example is presented to show the application of the proposed model.

A vessel should follow a planned route. However, when a target ship deviates from its original track, the subject ship should maneuver to avoid a ship-to-ship collision. This paper presents a trial maneuver-based method for collision avoidance that considers the potential area of water (PAW) for maneuvering that is available to the target ship. The initial conditions, including the position, speed, rudder angle, drift angle, and yaw rate of the target ship, are derived from automatic identification system (AIS) data. AIS data from Madura Strait were used to simulate collision avoidance. The PAW of the target ship was predicted based on a probability distribution of the initial conditions using a mathematical maneuvering group (MMG) model. Finally, a trial maneuver method for the subject ship was simulated to avoid a ship-to-ship collision. The MMG model for the simulation was developed to consider the effects of shallow water and wind and current disturbances.

The Car Sharing (CS) systems are promising services that are complementary to the traditional public transport forms and ensure a good level of flexibility and comfort. However, in order to make such systems efficient and competitive, suitable planning and management strategies are required. In this paper we deal with a crucial problem of the CS system management: the vehicle relocation problem. In order to obtain an as accurate as possible representation of the behavioral aspects of the CS service, a modeling approach based on the Unified Modeling Language has been used. Moreover, the proposed management strategies are analyzed and assessed by a discrete event simulation that considers a real case study in different scenarios.
