Modeling logistics processes in the context of maintenance

The dynamically changing business environment and constant competitive struggle force the search for solutions that best fit market needs. Today, the analysis of logistics chains consists of the comprehensive organization of the flow of materials and finished goods while effectively utilizing all available resources, in order to maintain task and functional capability.

Every downtime on the production line, or the occurrence of an unforeseen event, entails increased costs and the possibility of missing a deadline. Ensuring the reliability of production equipment involves monitoring the technical condition of machines, devices, and facilities, and diagnosing situations that threaten to cause delays and downtime resulting from improper functioning.
Modeling logistics processes involves staging subsequent activities, culminating in the creation of a system model. Thanks to the analysis of possible courses of action, a variant is chosen that can achieve optimal values under specific conditions and constraints. The purpose of this article is to analyze the functioning of the maintenance department in a production enterprise in the shipbuilding industry within the framework of Total Productive Management and to create a business process model that maps the processes performed during inspections, repairs, and maintaining the continuity of the technological park.

Business process modeling
Business processes are organizational activities that focus on implementing strategy. Their precise description is the basis for creating models that provide the opportunity for a deeper understanding of the organization’s structure and dynamics. All processes included in logistics chains should reflect the tasks and scopes of responsibility adopted in a given organization. Thanks to the analysis, it is possible to gain insight into the enterprise’s structure and understand the flow of resources. The function of a business model is to indicate the entity’s role in the value chain in which it participates. The business model serves as a basis for implementing changes. It indicates how to proceed in order to achieve the set goals in the best possible way, in the shortest possible time, and in the most repeatable (procedural) manner. For process orientation to be effectively introduced, the enterprise must be viewed as a whole, and related activities from various functional areas must be improved. For a detailed description of the processes occurring in the described example, the BPMS (Business Process Management System) notation was used. The notation is a proprietary method used in the Adonis system. Modeling is carried out in three stages. The first is the identification of main processes that define the specificity of the enterprise. The second stage involves their decomposition into sub-processes. The final stage is the creation of corrective maps, which consist of proposing changes necessary for the proper functioning of the processes. (…)
