Applying hierarchical tabu search to an adapted version of the flexible job shop problem

The scheduling departments of batch manufacturing plants have to repeatedly solve a complex scheduling problem for the operation of their production lines. This problem can be modeled as a flexible job shop problem (FJSP) in which a set of operations has to be assigned to a set of machines and then the order of operations on each machine has to...

Pushover analysis of a fixed steel offshore platform - Part I: Beam-column and strut elements in the INTRA program. Part II: Piles and pile groups under extreme loads

Part I: The computer program INTRA models the collapse behavior of trusswork offshore structures with the aid of two types of elements: 'Beam-column' elements, designed to simulate bending dominated failure of structural members, and 'strut' elements, that can represent normal force dominated failure. The behavior of both types of INTRA elements...
