Engineering process simulation model : Electrical Systems department, ABB Marine

The background for this thesis is formed by two documents: 3AFV6036386 Engineering Process Description. 3AFV6041649 Engineering Process Flow Chart. The purpose of the first mentioned document is to describe the project en-gineering process. The document focuses on engineering actions to meet the technical requirements of the customer and the man-hour budget of a project, on using standard products and system solutions and on support-ing commissioning. The second document is a graphical representation of the engineering pro-cess steps described in the first document. It was used as a basis for the simulation model. Both documents were needed to understand the com-plete engineering process. The aim of this thesis was to build up a simulation model of the proposed engineering process, and to define adjustable attributes for all the tasks. The process was modelled in appropriate detail to allow for the identifica-tion and calculation of the extra time invested by the resources. The engineering process was modelled using commercial discrete-event simulation software. The model was created in two phases; first the com-plete process was modelled based on existing documents, and then it was refined based on the interviews with the person of contact in the Electrical Systems and Projects Engineering Process department. Once the simula-tion model is finished, resources will be sized to reduce the extra-time in-vested in the engineering process. Therefore, the model itself is the main result of this thesis, because it al-lows for testing the complete process, and it acts as important validation for the department if any modification in the engineering process is ap-plied in the future
