Stochastic extension of cellular manufacturing systems: a queuing-based analysis
Clustering parts and machines into part families and machine cells is a major decision in the design of cellular manufacturing systems which is defined as cell formation. This paper presents a non-linear mixed integer programming model to design cellular manufacturing systems which assumes that the arrival rate of parts into cells and machine service rate are stochastic parameters and descri...
متن کاملHeaviness - an Extension of a Lemma of Y. Peres
We provide an elementary proof of Y. Peres’ lemma on the existence in certain dynamical systems of what we term heavy points, points whose ergodic averages consistently dominate the expected value of the ergodic averages. We also derive several generalizations of Peres’ lemma by employing techniques from the simplified proof. 1. The Lemma of Peres and its Immediate Generalizations The following...
متن کاملA simple proof of Zariski's Lemma
Our aim in this very short note is to show that the proof of the following well-known fundamental lemma of Zariski follows from an argument similar to the proof of the fact that the rational field $mathbb{Q}$ is not a finitely generated $mathbb{Z}$-algebra.
متن کاملSome Remarks on Hartogs’ Extension Lemma
Motivated by a result and a question by E. M. Chirka we consider the Hartogs’ extension property for some connected sets in C2 of the form K = Σ ∪ (∂Δ × Δ), where Σ is a possibly nonconnected compact subset of Δ×Δ ⊂ C2.
متن کاملAn Extension of the Lemma of Rasiowa and Sikorski
We prove an extension of the Lemma of Rasiowa and Sikorski and give some applications. Moreover, we analyze its relationship to corresponding results on the omission of types.
