Despite the progress in the development of simulation games and models for training in many areas, the post harvest produce sector seldom has been a subject of instructional tools. The game developed with produce sector in mind accounted for the complexity of the sector combining the systems dynamics and the systems thinking to model and simulate the essential elements responsible for meeting consumer demand. The game provides a participatory, hands-on experience to understand the concepts and develop skills desired in the post harvest fresh produce industry. A computer-mediated simulation game for this objective was developed in Windows environment. It uses the Stella software (a systems thinking software) to model the system and to develop the simulation equations. The game combines systems thinking and system dynamics to simulate essential relationships between links in the produce delivery. It models the critical elements of the post harvest system of fresh produce retailing faced by the manager of the produce department in a large retail outlet. The simulation emphasis the importance of correct ordering based upon deterministic and stochastic consumer demand, the delays in produce delivery by the system, perishability and a measure of financial assessment of the retailer performance. It can be used as a teaching tool by marketing, postharvest engineering and biology students and as a training tool by the produce department personnel in retail outlets to understand the dynamics of the post harvest marketing system.
