Guruh: 214-17. Toshev Osmon

4-Amaliy ish.

Mavzu. Teskari zanjir usuli.

Ishdan maqsad: Qoidalarning teskari zanjiri tushunchasi o’rganish va qoidalarning teskari zanjir usuli asosida o’quv markazi daromadini oshirishga yo’naltirilgan dastur ishlab chiqish.

Masalaning qo’yilishi: O’quv markazining yillik soffoydasiga qarab tahlil qiluvchi va holatdan kelib chiqgan holda foydani qanday sabablarga ko’ra kelganligi yoki nima sababdan foyda ko’rilmaganligini ko’rsatib beruvchi dastur tuzilsin.
FOYDA=DAROMAD-XARAJAT

Agar DAROMAD=XARAJAT bo’lsa, unda FOYDA=0 bo’ladi.

Agar DAROMAD

Agar DAROMAD>XARAJAT bo’lsa, unda FOYDA>0 bo’ladi.

Baliqchilikdan foyda ko’rgan holat uchun teskari zanjir usuli

1. 
   Chunki siz baliqchilikka ko’proq investitsiya kiritdingiz.
   
2. 
   Chunki siz baliq boqish uchun qulay joy tanladingiz.
   
3. 
   Chunki siz baliq boqishda to’g’ri yo’l tanladingiz.
   

Baliqchilikdanfoyda ko’rmagan hoalt ucun teskari zanjir usuli

1.Chunki siz yetarlicha investetsiya kiritnadingiz.

2.Chunki siz baliq boqish uchun qulay joy tanlamadingiz.

3.Chunki siz baliq boqishda no’to’g’ri yondoshingiz.

Xulosa

Ushbu amaliy ishni bajarish davomida men, teskari zanjir usuli haqida amaliy va nazariy bilimlarga ega bo’lib, uni amaliyotda qo’lladim.
