Hi everyone! We made maintenance optimization model for repairable deteriorating systems under imperfect preventive maintenance and free repair warranty. The main goal of the study is to determine a maintenance and replacement policy that minimizes the expected user cost rate, considering downtime, warranty expiration, and post-warranty costs. Is there someone here can help me review the model we created and gives critic? Thank you.
Hi everyone! I'm an undergrad student. We have a presentation of our optimization model tomorrow. Can someone here help us check our model and made a critique or suggestions to us please? That would greatly help us. Thank you.
Hello. My due date is every 2nd of the Month. Then, my bill is 1700 every month.
This May 2026, I only paid 1350. So there's still 350 left.
Now it's May 25, we lost internet because of overdue something. I checked the portal and I see that the next bill already came out, so 1700 (due on June 2) + 350 (the one I didn't pay last time) = 2050 in total.
Now, if I want to restore the internet, can I just pay 350? Then, 1700 on June 2? Or do I need to pay the full amount even though the deadline for the 1700 is June 2?
Please answer. Thank you.
Hello. Ang due date ko po kasi is every 2nd of the Month. Then, ang bill ko is 1700 every month.
This May 2026 po 1350 lang po nabayad ko. Kaya meron pa pong natirang 350.
Now May 25, nawalan po kami ng internet because of overdue something. I checked the portal po and I see po na lumabas na rin yung next bill so 1700 (due ng June 2) + 350 (yung hindi nabayaran nung nakaraan) = 2050 in total po.
Now po, if I want to restore yung internet, can I just pay 350? Then, 1700 sa June 2? Or need ko bayaran nang buo kahit June 2 pa deadline nung 1700 po?
Please answer po. Thank you.
