Within three years, the eight new businesses had achieved a complete turnaround, attaining significant increases in machine utilization and productivity.
This formulation is tested and illustrated on several ELSPs with varying levels of machine utilization and products demand perturbations.
The layout evolution effort is minimized and system performance metrics (i.e., average machine utilization and alternative replacement machines within the system) are maximized.
The model is developed to optimize the machine utilization and balance tool magazine capacity of a flexible machining workstation (FMW) in a tool-sharing environment.
Currently, efforts are being made by the industries to mitigate CO2 emission by the total vehicle weight optimization, machine utilization and resource efficiency.
This paper presents a preliminary analysis of the typical scheduling environment in semiconductor manufacturing involving multiple job families, and where more than one objective such as cycle time, machine utilization and the due-date accuracy needs to be simultaneously considered.
The analytical models require less computational effort than simulation models, and experimental results show that they accurately estimate important performance measures like average flow time, machine utilization, and setup frequency.
It is defined as the sum of two weighted functions, one for machine utilization and other for inter-cell movement with a weight factor; recommendation is in favour of equal weight for both functions (Chandrasekharan and Rajagopalan 1986; Nair and Narendran 1998; Sarker 1996; Wang 2003).
Some advantages of CMS such as simplification of material flow, reduction of transportation and queuing times, reduction of material handling cost and setup times, and the increase of machine utilization and throughput rates are declared in literatures (Muruganandam et al. 2005; Olorunniwo and Udo 2002; Wemmerlov and Hyer 1989).
The results demonstrate the capability of the proposed approach in setup time reduction, which in turn will improve machines' utilization, and increase the productivity and flexibility of the whole facility.
