Claim Text:
1. A system for handling conditional dependencies between alternative product segments of a production process modeled within a manufacturing execution system (MES), the system comprising: a common network; a number of data processing units connected to said common network and running MES software for controlling the production process operating production components; a production modeler within the MES software enabled to embed time-sensitive dependency information in each product segment for defining a start of execution in relation to another product segment, the production modeler being further enabled for embedding, in each of the product segments programmed for alternative execution, conditional dependency information including a specified condition and an associated sequence attribute indicating an order in which the specified conditions of the product segments will be evaluated in relation to the other product segment; and said MES software configured to check, during or at an end of execution of the product segment preceding alternative executions, one of the specified conditions which is specified as first by the sequence attribute and, if the condition, which is specified as first, is satisfied, executing the product segment corresponding with the condition, otherwise iterating a check for execution until the condition is satisfied.
