Optimization of material distribution process in productionlogistics systemsan--Take Zhongshan Jiebao Electronic Appliance Co.,Ltd.asan example[Abstract]The material distribution of production logistics is an importantprocess to connect all kinds of production activities.The quality of materialdistribution process affects production efficiency and production logistics cost.Takinga production enterprise as an example,this paper studies the material distributionprocess of its production logistics,and optimizes it to achieve the goal of reducingproduction logistics cost.The main idea is to establish the mathematical model ofqueuing theory,calculate the waiting time of material queuing,and take reducing thewaiting time and the cost caused by the waiting time as the optimization objective.First of all,we use Python Programming and genetic algorithm as a tool to find thebest material distribution route.According to the direction of the best distributionroute,the original distribution route is modified.The calculation results show that thetotal waiting time cost before modification is 1.65 yuan,and after modification,it isreduced by 1.25 yuan.Then,based on the optimized distribution path,the number ofdistribution personnel is modified,and the waiting time cost is reduced to 0.65 yuan.The continuous reduction of time cost shows that the objective of optimizing materialdistribution process is achieved.Finally,Flexsim is used to build the simulation modelof the distribution process,which verifies that the optimization method of changingthe number of distribution personnel is correct.[Keywords]Production logistics;material distribution;queuing theory;GeneticAlgorithm;Flexsim
