In the given paper we investigate the problem of constructing a simulation model for the optimization of current stock of divisible productions in the warehouse. Criterion of optimization is minimum of average expenses for goods holding, ordering and losses from deficit and damage to the goods per time of season. The ExtendSim 8 package has been used as the means of simulation. The numerical ex...
