Measurement of Supply chain Performance for Medium Construction Qualification Projects Using the AHP-SCOR Method Version 12

Abstract

Construction industry competition is not only limited to individual companies, but also competition between supply chain networks. Supply chain is a problem that constantly faced in construction. Supply chain players who contribute efficiently and productively can help the construction industr experience fierce competition. Good supply chain performance can improve quality efficiency, time, and cost to increase construction productivity. According to previous research, poor supply chain design can increased production costs by up to 10%. Each construction project has its own uniqueness that makes a difference in managing the supply chain from one another, including building construction. Building construction has a complicated construction process and involves many workers so good supply chain performance is needed so the construction process can run optimally and efficiently. According to the importance of the role of the supply chain in construction, a framework is needed to assess the performance of the supply chain on the project. This is in accordance with instructions from the Ministry of Public Works and Spatial Planning (PUPR) which states that supply chain performance activities must be measured to be efficient. There are many studies of supply chain performance measurement analysis, especially in construction, but there are no studies that measure medium construction projects in the Special Region of Yogyakarta (DIY). This study used qualitative research methods to assessed supply chain performance. The research was carried out in May 2022 with samples in the study, namely the construction of the Tipe I MAN Yogyakarta Dormitory Building which is a medium-scale construction building project. The data was taken using questionnaires that were distributed to the staff of project workers. The core process variables / supply chain criteria that used are plan, source, make, deliver, and return with work attributes of reliability, responsiveness, and agility. The resulting data is processed by the AHP method. Based on calculations using the AHP method and the SCOR matrix, a performance score from the supply chain obtained 85.6 which is included in the good category. The lowest score value is return responsiveness with a score of 0.77041 and the highest score value is source reliability with a value of 10.96349. Based on supply chain measurements of the MAN Yogyakarta Type I Dormitory Building Project, a score of 85.6 with a good category was produced.
