Picture this, its 5am of a summer month and a fleet of company vans is standing right outside a warehouse (or depot as it is commonly called). The depot supervisor is carrying a printed copy of today’s dispatch plan (combination of SKU and quantity) for each van shared by the sales manager of a region say West Delhi. The task of the supervisor now is to take out requisite stock from the depot and load each van in an optimal duration and send it on its designated route so that company’s goods can be delivered at a retail store on time. This is called loading a van. Similarly, once the van returns to the depot after delivering the products, the supervisor also must account for the unsold goods, returns from past sales and money collected during the day in form of cash, cheque, bank transfers or digital wallet.
