Majority of public transportation services are provided by government in developed countries. However, there are also private public transportation services which are autonomously directed. Although there are certain rules and regulations directed by the government, these companies and their actions are on their own responsibility. Minibus transportation service is provided by private craft in Turkey. In this study, historical background of the minibus transportation and its current operational process is investigated. Since each vehicle in the system represents a private craftsman, the operational process is challenging. It requires distribution of incomes equally. Due to uncertainty of incomes, there is not a possibility to create a cash pooling system. In Turkey, there are many different Minibus federations. Each federation represents a geographic region in which they carry passengers. The network might be very small or very large, depending upon the number of the terminals in the network. Due to variances in the transportation demands the vehicles do not run on the same route all the time. The demand defines the income levels for each route in the network and some income levels are relatively higher than the others. Therefore, it creates a scheduling problem. Before the implementation of the proposed dynamic scheduling, the vehicles were being distributed to the routes of network manually. This was causing a big problem because the people who held the responsibility to create the schedules every week were able to check the schedules of at most 4 or 5 weeks manually. The distribution of vehicles means the distribution of incomes in the network. Hence, in order to be fairer in distribution a computer based dynamic scheduling model is proposed and implemented for a pilot federation. The model reduced the complaints of craftsman about the schedules and provided equality in sharing the incomes of the network.
