center-randomize's Introduction

Exam Center Randomization Script

The goal of this script is to assign exam centers to students.

Steps

  1. Prepare input files in specified format.
  2. Run program and re run if -
    • Any school has students that have not been assigned a center.
    • Distribution across centers is uneven.
  3. Perform sanity check of distributed centers.
  4. Manually reassign impractical centers and odd lot allocations. Keep changes to minimum.

Allocation Guidelines

  • हरेक विद्यालयमा परिक्षार्थीको संख्या र परीक्षा केन्द्रको सिट संख्या लिने
  • हरेक विद्यालय र केन्द्रको गुगल म्यापबाट latitude, longitude निकाली दुरी निकाल्ने आधारको रुपमा प्रयोग गर्ने
  • विद्यालयबाट नजिक पर्ने केन्द्रलाई प्राथमिकता दिनुपर्ने
  • एक विद्यालयको परिक्षार्थी संख्या हेरी सकभर १००, २०० भन्दा बढी परीक्षार्थी एकै केन्द्रमा नपर्ने गरी बाँढ्न पर्ने
  • आफ्नै विद्यालयमा केन्द्र पार्न नहुने
  • दुई विद्यालयका परीक्षार्थीको केन्द्र एक अर्कामा पर्न नहुने, अर्थात् कुनै विद्यालयका परीक्षार्थीको केन्द्र परेको विद्यालयका परीक्षार्थीहरूको केन्द्र अघिल्लो विद्यालयमा पार्न नहुने
  • एकै स्वामित्व / व्यवस्थापनको भनी पहिचान भएका केन्द्रमा पार्न नहुने
  • विगतमा कुनै विद्यालयको कुनै केन्द्रमा पार्दा समस्या देखिएकोमा केन्द्र दोहोऱ्याउन नहुने
  • प्रत्येक पटक केन्द्र तोक्ने प्रोग्राम चलाउदा फरक फरक नतिजा आउने गरी ऱ्यान्डमाइज भएको हुनु पर्ने

Parameters

Variable Value Description
PREF_DISTANCE_THRESHOLD 2 Preferred threshold distance in km
ABS_DISTANCE_THRESHOLD 7 Absolute threshold distance in km
MIN_STUDENT_IN_CENTER 10 Min. no of students from a school to be assigned to a center in normal circumstances
STRETCH_CAPACITY_FACTOR 0.02 Factor determining how much center capacity can be stretched if needed
PREF_CUTOFF -4 Cutoff value for preference score allocation

centers.tsv

  • One entry per center.

prefs.tsv

  • Prioritize or deprioritize school and center pair. Negative pref score deprioritizes.
  • If pref score is less than PREF_CUTOFF center will be excluded from consideration.
scode	cscode	pref	reason
27xxx	27yyy	-5	same management
27yyy	27xxx	-5	same management
27aaa	27bbb	-1	last year's center

Command

To run school_center.py use the command below:

python3 school_center.py sample_data/schools_grade12_2081.tsv sample_data/centers_grade12_2081.tsv sample_data/prefs.tsv
