How does Peaple work?

The "Peaple" is a Decision Support System created within the framework of the FP6 European Integrated Project "ISAFRUIT", with the objective to simulate quality changes of apples and peaches along different supply chains, to meet the demands of consumers, and consequently stimulate the increase of fresh fruit consumption. The "Peaple" is planned as a multi-cultivar system which allows the design of various supply chains from harvest to the retail, with technological parameters (e.g. duration, temperature, atmosphere etc.) set by the user. The quality indices modelled for this DSS are fruit firmness, soluble solids content, acidity and colour (L*a*b* system).

Since the level of quality decay depends on the maturity of the fruits at harvest, the user is first asked for information on the fruit status at harvest. Then the stages of the supply chain have to be defined, including (CA) storage, transport and shelf life, and planned technological parameters for each chain stage typed in. Once the development of the supply chain is finished, the user can generate the graph presenting quality changes along the whole supply chain, or create the report presenting the status of the fruit batch at the end of each stage (and the description of the designed supply chain). The graph and report can be printed or saved as files. Also the sequence of supply stages (with their technological parameters) can be saved for future use in the DSS.

For better planning of the optimal supply chain, several chains can be simulated in one run and presented in a series of adjacent graphs or in one report.

Although the original “Peaple” is in English, the software is being gradually translated into several languages for the convenience of DSS users in different countries.
