Companies utilize a collection of resources to perform operational and supportive activities to achieve their objectives. Resources can be utilized efficiently or non-efficiently. In this research a mathematical model is proposed to increase the ability of resource utilization. Also an automotive supplier is investigated as a case study that has 15 main business processes and 19 resources those have been utilized by these processes. To evaluate the capability of resource utilization, efficiency factor (EF) measure is defined. For each obtained EF, cost values are estimated to increase efficiency of resource utilization. A questionnaire that has two sections is designed to attain needed data of the efficiency factors and cost values. Then the mathematical model is solved to maximize resource utilization measure by considering budget limit. Results of the model detect 14 improvement opportunities to increase efficiency of resource utilization in the business processes. Afterwards the detected opportunities are categorized to four groups to enable managers to prioritize improvement plans in implementation phase. Finally based on the above activities, an executive framework is presented.
