We study lot-size policies in a serial, multi-stage, manufacturing/inventory system with two key generalizations, namely (1) random yields at each production stage and (2) an autoregressive demand process. Previous research shows that the optimal policies in models with random yields (even in...

We consider a heuristic for serial production systems with random yields and rigid demand: all usable units exiting a stage move forward. We calculate optimal lots and corresponding expected costs for binomial, interrupted-geometric, and all-or-nothing yields. Our method is that it makes it easy...

Im Mittelpunkt der Serien- oder Sortenfertigung steht die Frage, wie häufig der Materialfluss unterbrochen werden muss und welche geschlossene Auftragsmenge eines Produktes jeweils hergestellt wird, es tritt also die Aufgabe auf, die kostenoptimierte Losgröße zu ermitteln. Lagerkosten,...
