In this paper, a mixed-model PC camera assembly line balancing case study is presented. The aim of the study isto establish different line configurations, for varying levels of demand. In the first stage of the study, a heuristicprocedure previously developed by some of the authors, based on the simulated annealing meta-heuristic, is usedto derive line configurations with a minimum number of workstations and a smooth workload balance between andwithin the workstations. In the second stage, the solutions provided by the heuristic are used as an input to discreteevent simulation models in which certain manufacturing parameters that analytical procedures have difficulty toaccommodate, namely, stochastic times, machine breakdowns, rework, etc. are introduced. These simulationmodels derive different performance measures (e.g. flow times and resources utilization) that provide operationalsupport and help fine-tune the line configurations.This paper reports on the collaborative study between the Department of Economics, Management andIndustrial Engineering of University of Aveiro and a major manufacturer of electronic consumer goods.q 2005 Elsevier Ltd.
