Abstract Reconfigurable manufacturing systems (RMS) are systems that are designed for cost effective response to changes in production requirements. Well-designed RMS should be able to cope with random changes in production requirements. RMS derived its name from the ability of a manufacturing system to be reconfigured. Reconfiguration is an iterative process that entails setting of the system configuration that is optimally fit for various purposes. Although RMSs are considered to be highly automated systems nowadays, still there is a human involvement in the process of reconfiguration itself. This enforces considering the human as the user of the RMS equipment on both physical and cognitive levels. Also, it is presumed that a highly usable manufacturing system will guarantee rapid system’s reconfigurability to be able to acquire high rate of customized output. Reconfigurable Manufacturing System is becoming a new manufacturing system paradigm that aims at achieving cost- effective and rapid system changes, as needed and when needed. This research investigates the level at which usability is contributing to the dynamic changeability of a reconfigurable manufacturing system. It addresses the equipment reconfigurability, usability, along with different environmental working conditions (physical work environment, organizational conditions, and task characteristics). A detailed analysis for each of the three factors was carried out to clearly identify the attributes affecting this factor. These attributes were then presented in a Cause and Effect diagram. The evaluation of all attributes was done via constructing single utility function for each attribute. Multi-attribute utility analysis (MAUA) was then implemented to integrate these utility functions in a single utility function with a three weights presenting the system’s reconfigurability, system’s usability, and the working conditions. To compute these three weights and estimate the level of usability importance in the reconfiguration process, weights are computed by applying the suggested function on a selected case study in Unilever-Mashreq. The study was focusing on all three production lines of the culinary factory. Qualitative interviews and likert scale questionnaires were used to collect all needed data in order to be able to test the utility function of the proposed model. The initial hypothesis states the usability has a significant effect on the re configuration process. |
