The Optimization Of Planning, Scheduling And Allocation Of Human Resources On Space Launching Project

The test of space launch is a huge project, in which all aspects of the arrangements need to be planned and scheduled ahead in order to enable the smooth implementation of product testing and launching. When the launch frequency is low, the planning and scheduling work can be finished by senior experienced staff to garantee basic requirement. However, when launch frequency is high, as more test are needed, many departments are involved, or many procedures are parallelly implemented or staggered or in parallel, the work of experience of senior staff can not meet the requirements of the development plan and errors and misses can easily happen. To avoid this situation, systematic analyses for launch and testing procedures are needed, using mathematical models to characterize the planning and scheduling and search for a feasible and optimal solution. Thus it can ensure the smooth progress of the work test launch and the stable and reliable resources supply, to ensure successful launch product testing.This paper focuses on three areas, including the optimal annual launch capabilities, optimal scheduling of tesing project and optimal allocation of human resources. The feasibility of constructing the optimization model is discussed. And the optimization equation is established. For each model, the parameters are estimated and calculation results are given, based on which further discussions are analyzed.The optimal annual launch capabilities are the optimal planning of lauch tasks of two launchers in a time period of one year. The existence practical problems, the mechanistic relations and the controlled variables are introduced. An optimization problem is then formulated. A simple introduction of solution algorithm is followd. According to the real example of the launch base, the values of parameters are estimated and optimal solutions are calculated.The optimal scheduling of ground testing for satellite launching is the problem of give the best arerangement of resource supply and the shortest testing time of the pre-launch ground testing process, based on a specific real launch case. Two optimization problems are formulated based on two modes:"fixed testing time optimal arrangement of resources supply" and "fixed resources supply-shortest testing time". The optimization formulations are applied in the real launch example, using the real data to estimate the model parameters and obtain the optimal results.Optimal allocation of human resources in a space launch site, is to get the best allocation of finite human resources. In order to quantitative characterize the allocation performance, queuing theory is applied, which can give specific working positions and matching results of work positions and task allocations. The simulation results shows that it can meet "zero error job action" requirement of the space launch.
