Workload smoothing in simple assembly line balancing
Azizoğlu, Meral (2018-01-01)
This paper considers a simple assembly line balancing problem with fixed number of workstations and prespecified cycle time. Our objective is to minimize the sum of the squared deviations of the workstation loads around the cycle time, hence maintain workload smoothing. We develop several optimality properties and bounding mechanisms, and use them in our branch and bound algorithm. The results of our computational study reveal that our branch and bound algorithm is capable of solving medium sized problem in...
Workload smoothing in assembly lines
İmat, Sadullah; Azizoğlu, Meral; Department of Industrial Engineering (2014)
In this thesis, we consider a simple assembly line balancing problem with fixed number of workstations and predefined cycle time. Our objective is to minimize the sum of the squared deviations of the workstation loads from the cycle time. We first present pure integer nonlinear programming model and then convert the model into mixed integer linear program. We develop several optimality properties and bounding mechanisms, and use them in our branch and bound algorithm. The results of our computational study ...
Workload Distribution Framework for the Parallel Solution of Large Structural Models on Heterogeneous PC Clusters
Kurç, Özgür (American Society of Civil Engineers (ASCE), 2010-03-01)
One of the main problems of substructure-based parallel solution methods is the imbalances in the condensation times of substructures when direct solvers are used. Such imbalances usually decrease the performance of the parallel solution. Thus, in this study, a workload distribution framework for such methods at heterogeneous computing environment is presented. The main idea behind this framework is to iteratively adjust the shapes of substructures so that the imbalance in their condensation times is minimi...
Workload, safety climate, and negative affectivity as the presumed moderators of the risk perception-organizational outcomes relationships
Geçer, Canan; Sümer, Hayriye Canan; Toker, Yonca; Department of Psychology (2014)
The main purpose of the present study was to examine the moderating role of workload, safety climate and negative affectivity in risk perception’s relationship with safety performance of employees, burnout, and job satisfaction in a high-risk work context. It was first expected that risk perception would be positively related to safety performance and then, in line with the moderation hypotheses, it was expected that high levels of workload would negatively affect (i.e., weaken) the relationships between ri...
Job shop scheduling using fuzzy logic
Bilkay, O; Anlagan, O; Kilic, SE (Springer Science and Business Media LLC, 2004-04-01)
In a flexible manufacturing system (FMS) scheduling problems become extremely complex, even for simple breakdowns, when dynamic uncertainties such as machine breakdowns and the uncertain arrival of jobs are taken into consideration. In the first stage of this study, a fuzzy logic-based algorithm for assigning priorities to part types that are to be machined is proposed. In the second stage, an operation-machine allocation and scheduling algorithm is presented. A criteria contribution equalizer is used in de...
