Capacitated p-median problem (CPMP) is a well-known facility-location problem, in which p capacitated facility points are selected to satisfy n demand points in such a way that the total assigned demand to each facility does not exceed its capacity. Minimizing the total sum of distances between each demand point and its nearest facility point is the objective of the problem. Developing an effic...

The facility layout problem is one of the fundamental production system management problems. It has a significant impact on overall efficiency. This paper introduces new that allows for choosing from multiple variants each facility. need most suitable selection while at same time optimizing other quality indicators represents optimization challenge. We build our previous work where single- and ...

This study aimed to illustrate assisted living facility (ALF) resident quality of life (QOL) prior intergenerational with graduate health science students and allowed investigation QOL in older adults during COVID-19. A mixed methods approach utilizing the Quality Life Scale (QOLS), Geriatric Depression Scale-15 item, demographics survey was utilized 10 participants at an ALF. Eight were recrui...

In this study, a production inventory model with phase type service times where customers join the system occur according to Markovian arrival process is discussed. When level positive, if an arriving customer finds server idle gets into immediately. Served leaves and on-hand decreased one unit of item at completion epoch. Otherwise, enters waiting space (queue) infinite capacity waits for get ...

The research type using Kirkpatrick’s Four Level model, which consisted Reaction, learning, behavioral, and result levels. samples were 20 former training participants. Data collected by...

This study investigated the utility of all of the above (AOTA) as a test option in multiple-choice items. It aimed at estimating item fit, item difficulty, item discrimination, and guess factor of such a choice. Five reading passages of the Key English Test (KET, 2010) were adapted. The test was reconstructed in 2 parallel forms: Test 1 did not include the abovementioned alternative, whereas Te...
