| Description | This paper proposes a practical approach for developing production planning tools in Small and Medium-sized Enterprises (SMEs). We focus on modeling material flow (products and intermediates) to keep things simple for production workers who will use the tool. Since these workers may not have specialized modeling knowledge, we represent the production flow as a network of processes, containers (objects), and connecting transport routes. Arrows on the connections show flow direction. This structure resembles a graph or Petri net, which we leverage for our development. We illustrate that every production flow failure or waste can be quantified as either an underflow or an overflow within an appropriate stack. To achieve this, we introduce the concept of a defect associated with a planning scheme. Specifically, the defect of a composed scheme is expressed as the sum of particular defects. This approach allows us to measure and address inefficiencies in the production process effectively. |
