M.Com. (Business Management) / The Rolling Stock Department (Rohnat) within Spoomet is responsible for the maintenance and repair of all classes of locomotives. One of the biggest problems at maintenance depots of Rolling Stock is to decide which faulty locomotives, withdrawn from service, must get preference for repairs. This problem is compounded at depots where different classes of locomotives are maintained and repaired. PURPOSE The purpose of this study is to determine critical factors and to create a decision model that can be used for project management at maintenance depots. This decision model must help maintenance depots of Rohnat to determine in which sequence different types of locomotives must be repaired to the advantage of Rohnat and Spoomet. METHOD OF STUDY The most suitable model that could be used to determine the repair sequence of locomotives was the MADM model. In this study, brain storming sessions and individual discussions were held with different Spoomet entities to determine critical factors that could be used in this model. The principles of the MADM model were explained to all parties concerned, whereby critical ABSTRACT factors affecting this model were discussed. Questionnaires were completed after the iscussions to confmn the critical factors that could be used in the MADMmodel. MADM - DECISION MODEL The MADM model is unique in the sense that financial and non-financial factors can be combined . The non fmancial factors which contribute to corporative success and which are left out in other models are however included in this model. The critical factors are further divided into two groups namely quantitative and qualitative. A conceptual model has been prepared in this study to give a better perspective of the workings and arrangements of weights, values and risks of this model. SUMMARY The most suitable model that could be used to determine the repair sequence of locomotives was the MADM It was possible to determine different critical factors that could be used in this model. Different Rolmat depots could use this model, but with different weights for each critical factor to suit their requirements. Critical factors could be added to or removed from this model to suit changing requirements.
