+                determinarea rutelor este folosit un algoritm. Acesta se bazeaza pe problema din teoria grafurilor
+                numita ‘Multi-Depot-Vehicle-Routing’, care determina traseul unui camion astfel incat sa colecteze
+                produsele pentru onorarea unei comenzi utilizand drumul cel mai scurt.
+            </p>
+            <p class="text">
+                Algoritmul va identifica prima oara depozitele in care se afla produsele dintr-o comanda primita ca
+                input. Dupa va ordona in ordine crescatoare (in functie de distanta fata de client) toate depozitele.
+                Dupa va itera prin fiecare depozit si va tine minte ce produse se afla in primul depozit, apoi al doilea
+                pana cand toate produsele au fost localizate. Dupa aceea va lua depozitele in sens invers si va crea un
+                JSON cu depozitele respective si produsele care trebuiesc luate de la un anumit depozit si il va salva
+                in folder-ul dedicat traseelor.
+            </p>
+            <p class="text">
+                Aceasta varianta de algoritm garanteaza faptul ca, in cazul in care chiar daca un depozit contine toate
+                produsele pentru a onora comanda, va putea gasi un drum mai scurt, chiar daca asta ar insemna sa
+                viziteze
+                un numar mai mare de depozite. Deoarece ordonam depozitele in ordine crescatoare in functie de distanta
+                fata de destinatie, dupa ce vizitam un depozit 'i' nu mai poate exista un alt depozit 'j' care sa fie in
+                acelasi timp mai aproape de destinatie fata de 'i' si sa aiba o parte / toate produsele necesare
+                onorarii
+                comenzii.
