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...

A pot culture experiment was conducted at the Department of Agronomy, Madras Veterinary College, Tamil Nadu and Animal Sciences University, Chennai, to study effect irrigation water nutrients on yield nutrient uptake fodder cowpea. The consisted two factors with three four treatments respectively. results indicated that application sewage along recommended dose farm yard manure inorganic enhanc...

Soil amendment by organic matter (O.M.) has been widely accepted as an efficient nutrient-management technique in agriculture. The study was conducted pot culture experiment at the Rajiv Gandhi South Campus, Barkachha Banaras Hindu University (B.H.U.) Mirzapur, which is located Vindhyan zone of Mirzapur district 25º 10” latitude, 82º 37” longitude with altitude 427 meters above sea level. soils...

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...

Constructed farms wetlands (CFWs) are increasingly being used to treat faecally contaminated ‘dirty waters’ from yard areas on livestock farms. The findings of the present study, undertaken at Pwllpeiran experimental CFW, West Wales, provide empirical data effectiveness CFWs in attenuating faecal indicator organism (FIO) concentrations and fluxes receiving waters which they discharge; insight i...

Planning the operational procedures in a railway marshalling yard is a complex problem. When a train arrives at a marshalling yard, it is uncoupled on an arrival yard and then its cars are rolled to a classification yard. All cars should eventually be rolled to the classification track that has been assigned to the train they're supposed to depart with. However, there is normally not enough cap...

The average American generates approximately 4.5 pounds of garbage per day, for a total of 196 million tons of trash per year, most of which ends up in landfills (Shortridge, 1993). Various government and private programs have been organized to divert part of this garbage (metals, plastics, paper and cardboard, and yard and food wastes) from landfills by recycling. Yard and food wastes often ar...
