Bir sistemin dinamiklerini belirleyen etkileşimleri anlamayı ve anlatmayı kolaylaştıran sistem davranışları, sistemin içinden ortaya çıkar ve birçok nedensel döngünün (veya geri besleme döngüsünün) sonucudur. Nedensel Döngü Diyagramları, yapının davranışı nasıl ürettiğini gösterir. Bir nedensel döngü şeması bir sistemdeki farklı değişkenler birbiriyle görselleştirmek için nasıl yardımcı olduğunu gösteren bir diyagramdır. Diyagram, bir dizi düğüm ve yaydan oluşur. Düğümler değişkenleri ve değişkenler arasındaki bağlantıları veya ilişkileri yaylar temsil etmektedir. Olumlu bir bağlantı, olumlu bir nedensel ilişkiyi ve olumsuz bir bağlantı, olumsuz bir nedensel ilişkiyi göstermektedir. Meyve ve sebzeler hasat sonrası yaşamlarını sürdürmekte olup kaliteleri düşmekte ve kayıplar oluşmaktadır. İstanbul önemli bir tüketim merkezi olup ürünlerin tamamına yakını uzak mesafelerden taşınmaktadır. Çalışmada tarladan sofraya kayıpların azaltılması için Nedensel Döngü Diyagramı oluşturularak konuya bütünsel bir yaklaşımla kayıpların azaltılması amaçlanmaktadır.

CAUSAL LOOP DIAGRAM IN FRUIT-VEGETABLE LOSSES

Öz

System behaviors that make it easier to understand and describe the interactions that determine the dynamics of a system arise from within the system and are the result of many causal loops (or feedback loops). Causal Loop Diagrams show how the structure produces the behavior. A causal loop diagram is a diagram that shows how different variables in a system help to visualize each other. The diagram consists of a series of nodes and arcs. Nodes represent variables and arcs represent connections or relationships between variables. A positive link indicates a positive causal relationship, and a negative link indicates a negative causal relationship. Fruits and vegetables continue their lives after harvest, their quality decreases and losses occur. Istanbul is an important consumption center and almost all of the products are transported from long distances. In the study, it is aimed to reduce losses with a holistic approach to the subject by creating a Causal Loop Diagram to reduce losses from farm to fork.
