Research And Application Of Erection Scheduling At The Dork

In recent years, China's low labor costs, because of the obvious advantages, and the development of the shipbuilding industry with some of the basic conditions for rapid development of China's shipbuilding industry has been 10 years in a row from the third into the world's second position. China's maritime trade and the increasing demand driven by demand for shipping products to maintain sustained prosperity. In this environment, China's shipbuilding industry should further improve their international competitiveness, the key lies in technological innovation and design.Erection Scheduling at the dork, one of the most important schedules in the construction schedule scheme, is the core plan in the shipbuilding project management. The closure effectively Erection Scheduling at the dork can improve the utilization of critical resources berth, shorten the cycle berth, so as to shorten the ship construction cycle, reduce the cost of ship construction. In order to make better use of computer technology to carry Erection Scheduling at the dork, to make programming more accurate and effective. This paper on the following several aspects.Firstly, this paper analyses the requirement of Erection Scheduling at the dork in logistic enterprises and the content correlate with it by researching the VRP model. This paper designs the structure of function ,the structure of system, the database and other aspects related to the system.Secondly, the paper studies the flow system construction of integrated area shipbuilding of shell, fixing and painting. and in accordance with the model put forward a set of plans in line with Shell Xi integration model of the construction plan system. And to study the closure of the network plans to carry the scheme in the system. On the Erection Scheduling at the dork of the plan. For planning process, using the resources constraints under the mandate of its algorithm to optimize and follow the steps of the algorithm for the design of algorithms in detail, using the Java language prepared by the algorithm procedures, application examples was verified.At last, to realizes the Erection Scheduling at the dork system under the frame which is based on J2EE software structure.
