Spatial Scheduling Optimization Algorithm for Block Assembly in Shipbuilding

A Simulation Model for Spatial Scheduling of Dynamic Block Assembly in Shipbuilding

Accurately predicting the required spatial resource for aggregate block assembly in shipyard production is difficult due to the following reasons: 1) lack of optimal block on-jig configuration and 2) the dynamic and stochastic nature of production system. Consequently, managerial objectives are seldom achieved without effective production planning and control. In this study, a look-ahead schedu...

Simulation of Block Assembly Process in Shipbuilding by Petri-nets

Shipbuilding Industry has undergone major changes in the past two decades. Maritime sector has grown rapidly and so has the competition. In order to survive in this competitive environment shipyards have to organize and utilize their resources at optimum capacity and efficiency. Planning and management of resources is a very crucial aspect of shipbuilding industry. There are many constraints on...

Optimisation of assembly scheduling in VCIM systems using genetic algorithm

Assembly plays an important role in any production system as it constitutes a significant portion of the lead time and cost of a product. Virtual computer-integrated manufacturing (VCIM) system is a modern production system being conceptually developed to extend the application of traditional computer-integrated manufacturing (CIM) system to global level. Assembly scheduling in VCIM systems is ...

Optimization Task Scheduling Algorithm in Cloud Computing

Since software systems play an important role in applications more than ever, the security has become one of the most important indicators of softwares.Cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. Presenting a proper scheduling method can lead to efficiency of resources by decreasing response time and costs. This rese...
