Nowadays, most consumable goods are produced and transported in batches. Within the globalized environment, the flow of these batches is raising dramatically to satisfy the recurrent demands of the increasing population. Planning the flow of these batches from suppliers to customers, through...

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...

The increased complexity of contemporary manufacturing makes it hard to maintain a predictable level of output. We consider several types of multistage systems in an environment where yield is random, production is in lots and demand needs to be satisfied in its entirety. For each possible...

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...

Under the impact of transition to the new post-industrial society, mass production recently faced the most numerous difficulties. They are caused by turbulences in the external environment in which companies operate, manifested in particular by enhancing the dynamism of markets and by deep...

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,...

We consider a production system consisting of N processing stages. The actual leadtimes at the stages are stochastic. The objective is to determine the planned leadtimes at each stage so as to minimize the expected total inventory costs, tardiness penalties, and a backlog penalty for not meeting...
