The integer aspect of the proposed model deals with the technicians' size and time, while the technicians' reliability is considered as a real-value decision variable.
Also, the proposed model results for different planning periods technicians size, maintenance time and reliability for the different kinds of maintenance task and technician's categories are presented.
The objective of this study was to develop a mixed-integer optimisation model that optimises technicians' sizes, workloads (service times), reliability, availability, performance (efficiency) and quality of workdone.
Also, the application of system dynamic modelling approach in establishing the interrelations among technicians' variables (time, size and reliability) and other maintenance parameters (spare parts) can be investigated as a further study.
The cost of satellite data acquisition, processing and analysis has recently plummeted, based mostly upon free data sources and analytical methods e.g., [42, 43], to a level requiring perhaps two to five trained technicians, depending upon the size and environmental complexity (e.g., topography, land use) of the tropical country.

This study is motivated by lack of information on how to optimise the technicians' costs, workloads, sizes and reliability of technicians.
Empirical findings show that the lab technician licensing requirements reduce the size of medical labs, which further lead to an increasing in the cost of performing various tests.
Obolensk now employs 1,125 scientists and technicians, about half its peak size.
