CHASM: A Combined Hierarchical Approach for Suppliers Management

In today's evolving and unpredictable supply chains, it is crucial for an organization to monitor its suppliers' performance in an efficient and tailored way. Managers need tools that could help them evaluate their suppliers according to their specific strategy. The CHASM (Combined Hierarchical Approach for Suppliers Management) model proposed in this paper aims to achieve this goal, by creating a simple and adaptable framework to evaluate and rank suppliers. What differentiates the CHASM model from other available tools is that it combines various recognized models into one single approach. In particular, the model assigns a hierarchy to a selection of different KPIs, assigns a value to each KPI for each supplier, calculates a supplier score using the sum of KPI values, while also considering multiple criteria in a single objective function. The potential of the CHASM model is discussed with respect to its capability of being adapted to different evaluation contexts and application needs.
