The New British Yard Standard

New bounds and algorithms for the transshipment yard scheduling problem

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...

British standard (BS) 5750--quality assurance?

BS5750 is the British Standard on "Quality Systems". Its equivalent in European Standards is EN29000 and in the International Standards Organisation ISO9000. This paper points out that these standards lay down formalised procedures and require documentation but do not ipso facto lead to quality assurance. The author points to the Japanese post-war industrial success as being an example of Total...

The General Yard Allocation Problem

The General Yard Allocation Problem (GYAP) is a resource allocation problem faced by the Port of Singapore Authority. Here, space allocation for cargo is minimized for all incoming requests for space required in the yard within time intervals. The GYAP is NP-hard for which we propose several heuristic algorithms, including Tabu Search, Simulated Annealing, Genetic Algorithms and the recently em...

Reading The Role of Yard in House

In today lives, daily trips of house inhabitants to out is made using closed staircase spaces or lobbies. Lack of a place for neighbourly relation results in less recognition and in some cases there is no neighbourly and friendly relationship.
