When you have some tasks, some jobs, or some other things that you have to do, not like Windows, sometimes it is difficult for us to do several thing at one time (we do not always be able to do some tasks together, but there are some that can be done together, such as thinking about your dream girl when you take a bath, walking while sleeping, etc).

Ketika kamu mempunyai beberapa tugas, pekerjaan, atau hal-hal lainnya yang harus kamu lakukan, tidak seperti Windows, kadangkala kita mengalami kesusahan untuk melakukan beberapa pekerjaan sekaligus dalam satu waktu. Tapi ada juga beberapa kegiatan-kegiatan yang dapat dilakukan sekaligus, seperti berpikir tentang cewek yang kamu taksir sambil mandi, berjalan sewaktu tidur, dll.

Example: You are a very SLIM^^ man, you have some tasks that you have to accomplish before you confess your love to her (the chosen one... by you of course). You want to do it just after her birthday (Wooo.. romantic! but You may ruin it, Risky! But you are very tough), you only have a plenty of time. Everyday, you need to eat 3 times (normal) + 8 package of snacks. Then, lunch time comes, you need to eat on time so you can keep your schedule, but your parent suddenly ask you to accompany her to a shopping center because she need to buy some napkins, she is running out of it. This morning, you haven't took a bath, horrible, the cute girls may afraid of getting too close to you. If you take a bath, it will need another 30 minutes, much longer then time necessary for eating. Oops! Your parent keep calling your name. How about that? (Is this another trash article? Ans.: Of course not, this is not trash or rubbish article).

Contoh: Kamu orang yang sangat KURUS^^, kamu ada beberapa tugas yang harus kamu selesaikan sebelum menyatakan cintamu padanya (yang dipilih... olehmu tentunya). Kamu mau menyatakannya tepat setelah ulang tahun dia (Wooo.. romantis! tapi Kamu bisa mengacaukannya, Resiko! Tapi kamu sangat tegar), kamu hanya punya banyak waktu. Tiap hari, kamu perlu makan 3 kali (normal) + 8 pak cemilan. Lalu, waktu makan siang tiba, kamu perlu makan tepat waktu supaya jadwalmu ditepati, tapi orang tuamu tiba2 menyuruhmu menemaninya ke shopping center karena dia butuh beli serbet karena sudah habis. Pagi ini, kau belom mandi, gawad, gadis imut itu mungkin akan takut berdekatan denganmu. Kalau kamu mandi, perlu 30 menit lagi, jauh lebih lama dari waktu untuk makan. Ups! Orang tuamu terus memanggil namamu. Gimana dong? (Apa ini sebuah artikel sampah lain? Jawab: Tentu tidak, ini bukan artikel sampah atau limbah).

You may just follow your schedule, but your parent may be disappointed, the worst case is... she will not give you any more money. OK... you can eat later, today you just need to betray your schedule (shame on you). You need to take a bath before going out, so then you take a bath and then accompany your parent to the shopping center. It seems you arrange your tasks (bathing, going out, and eating) based on which one has nearer deadline or which one has earliest due date.

Mungkin kamu mau ikut jadwalmu saja, tapi orang tuamu mungkin kecewa, kasus terburuknya... dia takkan memberimu uang lagi. Oke... makan bisa ditunda, hari ini khianati saja jadwalmu (payah kamu). Kamu perlu mandi sebelum pergi, jadi kamu mandi lalu menemani orang tua ke shopping center. Kelihatannya kamu menyusun tugas-tugas (mandi, pergi, dan makan) berdasarkan mana yang deadline atau tenggatnya paling dekat/awal.

Actually, there are some "Priority Decision Rules" that we can use to arrange our tasks, such as:
(Tips: determine your due date or allocation time for the tasks first)

  1. First Come First Serve - do task which come before the others first. In that case, it would be eating first (you have scheduled it since a long-long time ago), then going out and bathing. The opposite of this rule is Last Come First Serve. Both rule widely used in many areas such as queueing, accounting, shop floor control, etc.
  2. Shortest Acting Time - do the task which require shorter time to be done first. In that case it would be eating first, then bathing and going out. Using this rule may result the lowest tasks completion.
  3. Shortest Total Acting Time Remaining - do the task with shortest total acting time remaining.
  4. Earliest Due Date - do the task which have earlier due date first. Just like the example.
  5. Fewest Sub-Tasks - do the task which has fewer sub-task. If when you bathing you need to wash your body first (first sub-task), then using soap to your body (second sub-task), then..., until you finish bathing. How many sub-task determined which you do first.
  6. Slack Time - Slack time is due date minus acting time. Do the task with smaller slack time first.
  7. Your own priority - If you put the girl in the highest priority, your parents in the second place, and yourself in the lowest place, anything happens (in the case), eat first then going out and bathing.
  8. q(^_^)p "et cetera..."

How about that, which one will you choose? (You may choose some, because you may need some rules).

Sebetulnya, ada beberapa "Aturan Penentu Prioritas" yang bisa digunakan untuk mengatur kegiatan kita, seperti:
(Tips: tentukan tenggat atau waktu yang dibutuhkan dari tugas-tugasnya dulu)

  1. First Come First Serve - lakukan tugas yang datang duluan daripada tugas lain. Kalau contoh, berarti makan dulu (kamu menjadwalkannya sejak dulu kala), lalu pergi dan mandi. Kebalikannya aturan ini Last Come First Serve. Kedua aturan banyak dipakai dalam berbagai bidang, seperti antrian, akuntansi, kendali lantai toko, dsb.
  2. Shortest Acting Time - lakukan tugas yang perlu waktu lebih sedikit dulu. Dalam contoh, lakukan makan dulu, lalu mandi dan pergi. Aturan ini mungkin menghasilkan penyelesaian tugas paling sedikit.
  3. Shortest Total Acting Time Remaining - lakukan tugas yang sisa waktu pelaksanaan totalnya paling pendek.
  4. Earliest Due Date - lakukan tugas yang tenggatnya paling awal. Seperti di contoh.
  5. Fewest Sub-Tasks - lakukan tugas yang sub-tugasnya lebih sedikit. Kalau waktu mandi kamu perlu gosok badan dulu (sub-tugas pertama), lalu menggunakan sabun ke tubuh (sub-tugas kedua), lalu ..., sampai selesai mandi. Berapa sub-tugas menentukan mana yang dilakukan dulu.
  6. Slack Time - Slack time adalah waktu tenggat dikurangi waktu pelaksanaan. Lakukan yang slack timenya paling sedikit.
  7. Prioritas pribadimu - Kalau gadis itu kamu tempatkan di prioritas tertinggi, orang tua kedua, dan kamu sendiri prioritas paling rendah, apapun yang terjadi (pada kasus ini), makan dulu lalu pergi dan mandi.
  8. q(^_^)p "dan lainnya..."

Gimana menurutmu, mana yang kamu pilih? (Boleh pilih beberapa, karena mungkin perlu beberapa aturan).

i think ur next task if to write a software that will do the scheduling for us. cos if we are to do the scheduling according to the above rules. it will waste a lot of time (recall question 1 of sc303 sem 1 2005/2006 ) and that amount of time we oso need to plan into our daily schedule.

You still can use what we call concurrency mode or sacrifice mode. Concurrency mode: to do more than one actions in one period of time, you can eat when you go shopping. Becoz each of our cells is a unit of work (or we can say that every cell is a processor), means our organs consist of many processor, hence we should be able to do concurrency better than computer. Sacrifice mode: different from computer that has to do all the tasks, we, human, can sacrifice some actions that are not necessary to be done. E.g. your body smells quite nice although you didnt take a bath, then you can allocate your time for taking a bath for other purpose. Have a nice try of this two methods ^^
