The digitalization of logistics processes is often based on distributed models and decentralized control. As these logistics models constitute an important part of Industrie 4.0 concepts they must be powerful enough to cover dynamic processes and must enable a host of functions such as goal-oriented, reactive, pro-active, communicative, cooperative...
Chapter
Material handling is an important process in the mining industry because of its high operational cost. In this process, shovels extract and load materials that must be transported by trucks to different destinations at the mine. When a truck ends an unloading operation, it requires a new loading destination. If a centralized system provides destina...

Process mining is a promising way to extract insight knowledge on business processes in manufacturing and logistics. However, implementing process mining is challenging in dynamic and complex environments as the discovered process models may not reach the aspired quality. As a result, current process mining solutions do not hold in practical situat...
