Often, these vessels returned to Central America empty. This resulted in high carbon emissions and high costs. Therefore, importers switched to reefer containers which are shipped to Europe by liner cargo services. However, the amount of spoiled bananas increased with that change. Now a research project has developed the so called “Intelligent Container”. This Intelligent Container is able to calculate the green life of its cargo and this leads to the feasibility of quality driven distribution. Thus, the losses of bananas should be decreased and both transport costs and carbon emissions be reduced even further.

In logistics networks the creation of value at the nodes by means of rapid turnover is important, so that the availability of the production factor “machine” is essential. The increase in efficiency of support processes encompasses among others the maintenance of machines and installations. Within the paper, a procedure model with case study is presented, which illustrates the change-over to a condition-based maintenance strategy in the seaport surrounding.

Possible investments into these new technologies must meet economic criteria and generate a certain business value. Anyhow, estimating all cost factors and saving opportun-ities is difficult due to uncertainty in input data. This paper presents a review of current approaches to determine the business value of RFID systems. Moreover, it points out the most important factors that influence the busi-ness value and proposes additional concepts to handle uncertainty in the calculation of the business value of an RFID system.

For example, fruits in cold chain logistics networks are very sensitive to mould and tend to perish. This can cause huge losses during transport, because the state-of-the-art reefer containers are only able to control the temperature but not in relation to the fruit condition. The 'Intelligent Container' is able to monitor the condition of fruits precisely as well as to track its geographical position.

Such corridors allow the dynamic change of allocations of container to customer order assignments. These corridors increase the flexibility of the decision-making process. Therefore, a simulation model will be developed and used in order to evaluate the potential of the new scheduling method based on the concept of the ‘intelligent container’ and qCODC.

Based on the development of relevant sensory parameters, the predictive model was developed by combining a linear primary model and the Arrhenius model as the secondary model. Then a process analysis was conducted to define general requirements for the implementation of the temperature-based model into a meat supply chain. The required hardware and software for continuous temperature monitoring were developed in order to use the model under practical conditions. Further on a decision support tool was elaborated in order to use the model as an effective tool in combination with the temperature monitoring equipment for the improvement of quality and storage management within the meat logistics network. Over the long term, this overall procedure will support the reduction of food waste and will improve the resources efficiency of food production.
