基于关键链的航天多项目稀缺资源均衡分配

Balanced Allocation of Aerospace Multi-project Scarce Resources Based on Critical Chain Management

针对航天企业多项目并行推进过程中存在稀缺资源争夺问题,提出了一种基于关键链的资源配置优化方法。通过为关键链上使用稀缺资源的活动增加稀缺缓冲,减小了稀缺资源分配不确定性对项目进度带来的影响。为了使稀缺资源在多项目并行执行时发挥最大效用,结合航天型号项目特点建立了多项目稀缺资源均衡分配的数学规划模型,并采用遗传算法对实际案例进行求解,证实了模型在优化资源分配方面的有效性。提出的多项目稀缺资源配置管理方法为类似多项目进度管理和优化提供了有益参考。

In order to solve the competing problem of scarce resources in parallel multi-project management of aerospace enterprises,an optimization method of resource allocation based on critical chain is proposed.By adding scarce buffers to the activities using scarce resources in critical chain,the impact of uncertainty in scarce resources allocation on project schedule is reduced.In order to make the best use of scarce resources in the parallel execution of multi-project,a mathematical programming model for the balanced allocation of aerospace multi-project scarce resources is established.The model considers the characteristics of aerospace model project.Genetic algorithm is used to solve the mathematical programming model of an actual case.This model is proved to be effective in optimizing resource allocation.The allocation and management method of multi-project scarce resources proposed provides a useful reference for similar multi-project schedule management and optimization.
