Purpose – The purpose of this paper is to present a hybridized technique for analyzing the stochastic behavior of an industrial system. The feeding system of a paper mill situated in North India producing 200 tons of paper per day has been considered for analysis and efforts have been made to...

Purpose – The purpose of this paper is to describe an adaptive approach for diagnosing faulty nodes in a wireless mobile environment. Design/methodology/approach – Based on a diagnosis approach that has been previously developed for wired networks. A discussion of the novel diagnosis...

Purpose – The purpose of this paper is to develop an efficient method for solving a vehicle scheduling problem (VSP) in 2D industrial environments. An autonomous vehicle is requested to serve a set of work centers in the shop floor providing transport and delivery tasks while avoiding...

Purpose – The purpose of this paper is to solve the problem of committing electric power generators (unit commitment, UC), considering network constraints. Design/methodology/approach – The UC is first solved with a local search based meta‐heuristic, following the assumption that all...

Purpose – Stereo vision is an attractive perception technique for mobile robots navigation. Stereo matching is a crucial part of stereo vision and its precision dominates the precision of reconstruction. Based on a geometry constraint applicable to natural terrain, the purpose of this paper is...

Pupose – The purpose of this paper is to show that a fingerprinting code is a set of code words that are embedded in each copy of a digital object, with the purpose of making each copy unique. If the fingerprinting code is c ‐secure, then the decoding of a pirate word created by a coalition...
