In a rapidly changing environment, many health-care systems are forced to survive with rising costs and the need for proper resources utilization. To address the requirements for effective strategic planning, business process reengineering (BPR) is inevitable for health-care systems. This study aims to focus on the reengineering of central sterilization unit’s business processes to obtain performance improvement and efficiency. With the obtained new process design, it is expected to get standardization in all level of the central sterilization unit.

This paper presents a BPR method for modeling the system in health-care sector to improve the productivity of the sterilization process of surgical equipment. The case study is conducted in a large hospital in Istanbul, Turkey. First, “as-is” process is modeled and the problems are determined. Then, solution methods are developed and the target system (to-be process) is redesigned and the workflows of each phase are remodeled by using ARIS tool. Enterprise resource planning (ERP)-driven BPR is used to reengineer the current processes and the future processes are operated through the modeled ERP system. Finally, by using a statistical analysis, performance of the new process is compared with the existing process using the first data obtained from the case hospital.

In many sterilization services, the control procedures are rarely used. Thus, an ERP solution is developed to automate sterilization tasks and track down the information flow. With the ERP solution, it is possible to track in which dates, where and by whom the items are processed. On the other hand, in the sterilization process, the sets are used efficiently according to the last sterile dates of the items. Also, with the ERP system, it is possible to reduce unnecessary paper usage and this gives the hospitals the opportunity to be more ecological and sustainable. As a result, a centralized sterilization process with an IT support provides efficiency, economy and patient safety.

This study seeks for the potential benefits of an ERP implementation in health-care sector. As a result of this project, improvements in productivity, cost and quality are expected in sterilization processes because the new process design will bring automation, human-related error reduction and equipment tracking system. For this purpose, a business process management software is developed and implemented to the central sterilization unit so that the information flows more safely and the managers can track the results quickly by charts and reports.

Paper aims to an alloy development study was carried out to increase the mechanical properties of cylinder heads.

AlSi12 alloys are used to manufacture the compressor head cylinder by high-pressure casting for easy casting and superior properties. Therefore, 1.1%, 2.4% and 3.1% Mg were added to AlSi12. The microstructures of the produced samples were characterized by optical microscope, scanning electron microscopy, energy dispersive spectrometry and X-ray diffraction methods. Hardness and tensile tests as well as Charpy impact tests were performed. Wear tests were also carried out on the pin-on disc tester, and then the wear performance was examined on the tester, which simulates the actual operating condition.

AlSi12 has primary Si and eutectic Si in the Al matrix. However, alloys of Mg with AlSi12 have other intermetallics such as Mg₂Si and ß-Fe, as well as primary Si and eutectic Si. Hardness and tensile strength as well as improved wear performance with increased Mg content.

In this study, wear performance test to simulate the operation of the cylinder head produced by high pressure casting from AlSi12 alloy moreover tensile test, hardness test and impact test were performed. Therefore, in this study, the wear performance of the compressor head produced by high-pressure casting method by adding three different amounts of Mg to AlSi12 alloy was investigated.
