The supply chain of perishable products like flowers, fruit or medicines needs to be controlled. Due to the various parties involved in this supply chain, maintaining the proper temperature of the products and accurate tracking and tracing of the products may be challenging. In this research project models that describe the deterioration of fresh products as a function of their temperature need to be determined. Being able to predict the deterioration of perishables allows a proper system design of their supply chain. Tracing and tracing as well as logging product data may be part of a new Internet of Things based data management system which needs to be developed.
