(2016): Porównanie systemów sterowania zapasami ze zmiennym opóźnieniem dostaw i zaburzonym zapotrzebowaniem: cyklicznego oraz z regulatorem PD i predyktorem Smitha.

Control systems structures based on mathematical discrete equations are given for optimization: a Periodic Inventory System with adaptive maximal inventory level and Proportional-derivative Inventory Control System with Smith predictor and adaptive reference stock proposed by the authors in previous works. Parameters were selected for each of the control system structures through solving bictriterial optimization task for a specific scenario of variable market demand using SPEA2 in Matlab/Simulink. In this article, we mainly highlight which control structure reaches better performance taking account probabilistic disturbance in market demand.plUznanie autorstwa-Użycie niekomercyjne-Bez utworów zależnych 3.0 Polskainventory control systemautomated order systemtime-varying inventory modelSPEA2bicriterial optimizationinventory optimizationdiscrete-time systemsDyscyplina::Nauki inżynieryjno-techniczneArticle
