Large-lot exurban landscapes could incorporate ecological design in order to contribute ecosystem services. In our study, we use a survey of 126 Southeast Michigan homeowners to examine respondents’ stated preferences for residential yard images, and compare those with reported current use and management of their actual yards. We found that stated preferences are not necessarily related to actu...

In a modern rail–rail transshipment yard huge gantry cranes transship containers between different freight trains, so that hub-and-spoke railway systems are enabled. In this context, we consider the transshipment yard scheduling problem (TYSP) where trains have to be assigned to bundles, which jointly enter and leave the yard. The objective is to minimize split moves and revisits. Split moves a...

This paper reports the findings of using multi-agent based simulation model to evaluate the sawmill yard operations within a large privately owned sawmill in Sweden, Bergkvist Insjön AB in the current case. Conventional working routines within sawmill yard threaten the overall efficiency and thereby limit the profit margin of sawmill. Deploying dynamic work routines within the sawmill yard is n...

Yard crane is an important resource in container terminals. Efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. This paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is NPHARD in nature. In other words, one of the most important constraints in...

In this paper, we address workflow management system for automatically operating yard management system which can fill up a gap between transportation and warehouse management system in supply chain management. But, it is difficult to find an optimal solution for yard operation problems because of its dynamic complexities. Instead, we propose workflow management system which describes the autom...

In general, modern computer systems are distributed systems. Such systems are implemented as computer networks, whose components jointly use and exchange data. To describe distributed systems at abstract level client-server model can be used. In terms of this model, client makes invocation, containing all necessary parameters, on server. Server receives the invocation, performs needed actions a...

This reasearch studies ACO algorithms for the switch engine scheduling in a Railroad Yard. The cars are moved individually or grouped into blocks by a set of locomotives called switch engines which are dedicated to moving around the cars in the yard. The need for moving comes from the fact that the arriving trains are disassembled into blocks of cars, undergo some operations like, loading , unl...

Abstract—The paper is focused to the evaluation railway tracks in the Slovakia by using Multi-Criteria method. Evaluation of railway tracks has important impacts for the assessment of investment in technical equipment. Evaluation of railway tracks also has an important impact for the allocation of marshalling yards. Marshalling yards are in transport model as centers for the operation assigned ...

We introduce a new problem arising in small and mediumsized container terminals: the Two-Dimensional Pre-Marshalling Problem (2D-PMP). It is an extension of the well-studied Pre-Marshalling Problem (PMP) that is crucial in container storage. The 2D-PMP is particularly challenging due to its complex side constraints that are challenging to express and difficult to consider with standard techniqu...

This paper deals with research related to the needs and feasibility of introduction of integrated wired/wireless industrial communication networks and takes as an example the real plant of the Sugar Refinery in Brcko, Bosnia and Herzegovina. For purposes of research was used the Emerson Process Management calculator "I/O on Demand" which provides unlimited flexibility field device that contains...
