Network planning method for developing complex engineering systems
The article was published in issue no. № 2, 2014 [ pp. 22-26 ]Abstract:The problem of developing a performance planning method for structural-complicated projects. These projects can also include development of complex engineering systems, such as weapons and military equipment, power engineering facilities, industry and transport facilities is formulated and formalized. A project is a set of operations necessary to ach ieve the purpose. The duration of every operation is known. They are conne cted by order relation (obligatory precedence). A tran-sition to a market economy and modifications in domestic and international situation with crisis developments in national economy have lead to a necessity of critical analysis of methods for maintening state requirements for production and new approaches to these problems solution. The proposed solution method is based on network planning method, on the idea of critical path optimisation. Known methods are improved based on the dynamic programming scheme . The critical path of the project graph defines performance time of the project. A cooperation of project performers is formed based on a solution of the assignment problem using a dynamic programming method and the offered algorithm, that allows consider ing the works precedence ratio defining project structure. Enterprise industrial engineering is based on rational combination of all basic, auxiliary and serving processes in time and space. Singularities and methods of this combination are вшааукуте in various working conditions. At the same time industrial engineering should be correspond to general principles. They are continuity, proportionality, rhythm, parallelism concern. The offered method allows implementing these principles.
Аннотация:Сформулирована и формализована задача разработки метода планирования выполнения структурно-сложных проектов, к которым можно отнести и разработку сложных технических систем, таких как вооружение и военная техника, объекты энергетики, промышленности и транспорта. Под проектом будем понимать совокупность операций, необходимых для достижения цели. Длительность каждой из них известна, и они связаны отношением порядка (обязательным предшествованием). Переход к рыночным экономическим отношениям и изменения во внутренней и международной обстановке, осложненные кризисными явлениями в национальной экономике, объективно обусловливают необходимость критического анализа методов обеспечения государственной потребности в продукции и вы-работки принципиально новых подходов к решению этих задач. Метод решения задачи основан на применении метода сетевого планирования, на идее оптимизации критического пути. При этом известные методы доработаны на основе схемы динамического программирования. Критический путь графа проекта определяет время выполнения проекта в целом. Формирование кооперации исполнителей проекта основано на решении задачи о назначениях с использованием метода динамического программирования и предложенного алгоритма, позволяющего учесть отношение предшествования работ, определяющее структуру проекта. В основе организации производства на предприятии лежит рациональное сочетание во времени и в пространстве всех основных, вспомогательных и обслуживающих процессов. Особенности и методы этого сочетания разнообразны в различных производственных условиях. Однако при всем многообразии последних организация производственных процессов должна быть подчинена некоторым общим принципам. К ним относятся непрерывность, пропорциональность, ритмичность, параллельность. Предложенный метод позволяет реализовать перечисленные принципы на практике.
