(99m)Tc is the most widely used radionuclide in nuclear medicine. The reactor stoppages that occurred in recent years illustrated the vulnerability of the availability of radiotracers for imaging. With many of the reactors due for shutdown over the next 5-10 y, alternative routes to producing the (99)Mo/(99m)Tc pair are being explored. This brief review examines how we have reached this situati...

This study examines the impact of Total Productive Maintenance (TPM) implementation on an organization in terms of productivity and quality levels. The human resource aspect was investigated to assess motivation of operators through training to reduce set up times, change over stoppages, defects rate and resource wastage on the shop floor. Total Productive Maintenance (TPM) implementation case ...

In the competition to excel in Industrial 4.0 race, companies especially Semiconductor Industry, strive attain efficiency by removing process bottlenecks, improving productivity and increasing machine availability during operation. As so, this research was conducted analyze machine’s based on various preventive maintenance (PM) scheduling. A model developed WITNESS 14 Manufacturing Performance ...

This paper addresses a multi-objective mixed-model two-sided assembly line balancing and worker assignment with bottleneck analysis when the task times are dependent on the worker’s skill. This problem is known as NP-hard class, thus, a hybrid cyclic-hierarchical algorithm is presented for solving it. The algorithm is based on Particle Swarm Optimization (PSO) and Theory of Constraints (TOC) an...

With the dramatic growth of nonlinear loads, it is desired to improve active filters performance and enhance their capacity. One of the most favorable methods is applying distributed active filter system (DAFS) in which leads to minimizing the cost, weight & size .The main purpose of this paper is to determine the locations and sizes of distributed active filter system (DAFS) With emphasis on r...
