This paper proposes a method for monitoring the structural health of concrete bridges in Iran. In this method, the bridge condition index (BCI) of bridges is determined by the analytical hierarchy process (AHP). BCI constitutes eight indices that are scored based on the experts’ views, including structural, hydrology and climate, safety, load impact, geotechnical and seismicity, strategic importance, facilities, and traffic and pavement. Experts’ views were analyzed by Expert Choice software, and the relative importance (weight) of all eight indices were determined using AHP. Moreover, the scores of indices for various conditions were extracted from experts’ standpoints. BCI defines as the sum of weighted scores of indices. Bridge inspectors can examine the bridge, determine the scores of indices, and compute BCI. Higher values of BCI indicate better conditions. Therefore, bridges with lower BCI take priority in maintenance activities. As the case studies, the authors selected five bridges in Iran. Successful implementation of the proposed method for these case studies verified that this method can be applied as an easy-to-use optimization tool in health monitoring and prioritizing programs.

Then, the gave scores of experts were assigned to indices for various conditions. Bridge inspectors can examine the bridge, determine the scores of indices, and compute BCI. Higher values of BCI ​​indicate better conditions. Therefore, bridges with lower BCI take priority in maintenance activities. Five bridges in Iran, Semnan province, were selected as the case studies, and BCI calculation of these bridges was conducted.

This paper proposes a method for determining the bridge condition index (BCI) in concrete bridges, which is based on the views of bridge experts. First, eight indices were defined for a concrete bridge including structure, hydrology, safety, load impact, geotechnical and seismicity, strategic importance, facilities, and finally traffic and pavement. Each index consists of several sub-indices. Next, a series of questionnaires about the relative importance of indices and their sub-indices were prepared and distributed among bridge experts. Experts’ views were analyzed by Expert Choice software and the relative importance (weight) of each index and each sub-index was determined using the analytical hierarchy process (AHP). Then, based on experts’ views, an average score was assigned to each sub-index for any condition. Now the bridge inspectors can examine the bridge and determine the scores of sub-indices. Each index’s score is the sum of the weighted score assigned to its’ sub-indices and BCI is the sum of weighted scores assigned to indices. Higher values of BCI indicate a better condition. Therefore, bridges with lower BCI take priority in maintenance activities. To apply the proposed method, five bridges were selected in Semnan province, Iran, and BCI calculation of these bridges were conducted.

Abstrack Good University Governance is needed by all higher education institutions that want to compete in producing good quality colleges. One of them is STT PLN which has a vision of realization of modern universities, independent and superior in the field of energy and electricity. To achieve good management governance, an objective, accountable and transparen,t assessment is required in recommending a lecturer to occupy a structural position. The process of determining attribute criteria, sub criteria and alternatives using the input of expert respondents in the form of questionnaires are processed by using statistical methods Cochran Q Test to obtain the decision attributes used in the study. While the analytical techniques in determining the priority weight of the alternative that will be done, using Analytical Hierarchy Process (AHP) method approach with data processing tool using Expert Choice software. Keywords : Good University Governance, Lecturers, structural positions, Cochran Q Test, Analytical Hierarchy Process (AHP)

It is attempted to identify and prioritize the accident prone points (black spots) in “Iraanshahr-Sarbaaz-Chabahar” road located in Baluchistan, Iran, without no use of accident data but rather using Analytic Hierarchy Process (AHP), which is the enhanced procedure of road safety audit technique. First, by surveying the whole route, all factors that could influence accidents in this road were specified; then the route was divided into eight sections; this division was performed based on the uniformity and homogeny of each section in terms of geometric design and regional conditions. In each section, potentially hazardous locations were identified and some questionnaires were prepared, which were filled by 5 road traffic experts familiar with the route; then the collected data were analyzed by Analytical Hierarchy Process (AHP) using Expert Choice Software and the black spots were identified and prioritized. Finally, these black spots were compared with the black spots that had been obtained by traffic police based on accident data.

Structural health monitoring is a promising way for evaluating the integrity and safety of large-scale bridges, and crack monitoring is thought to be a challenging problem in this field. An improved design based on smart film for monitoring crack width of concrete bridges is proposed in this paper. Experiments are also implemented to verify the effectiveness of this design.

Pariwisata di Sumatera Barat khususnya di Kota Padang dari berbagai potensi objek wisata yang ada terutama sekali potensi objek wisata bahari yang potensial untuk dikembangkan. Pada penelitian ini penulis mengangkat 3 objek wisata bahari yang dijadikan kawasan studi, yaitu Pantai Bungus, Pantai Nirwana dan Pantai Pasir Jambak, dari ketiga objek wisata tersebut maka penulis mengangkat penelitian yang berjudul Prioritas Pengembangan Objek Wisata di Kota Padang. Metode pendekatan yang digunakan dalam analisis studi adalah Metode Analisis AHP (Analytical Hierarchy Process) yaitu menggunaan variabel ukur Daya Tarik (Attraction), Fasilitas (Amenity), Aksesibilitas (Accessibility), Kelembagaan (Ancilliary) ) yang terkait objek wisata. AHP (Analytical Hierarchy Process) merupakan suatu model yang memberikan kesempatan bagi setiap orang untuk membangun gagasan, mendefinisikan masalah dengan membuat asumsi mereka masing-masing dan memperoleh pemecahan yang diinginkan. Perhitungan AHP dapat dilakukan dengan cara manual yaitu dengan menggunakan program Microsoft Excel maupun dengan Software Expert Choice. Namun dalam penelitian ini peneliti mengolah data menggunakan program Microsoft Excel untuk mengetahui prioritas pengembangan objek wisata di Kota Padang. Proses analisis metote AHP ada tiga tahan yaitu : (1) tujuan analisi : menentukan prioritas pengembangan objek wisata, (2) kriteria : daya tarik, fasilitas, aksesibilitas, kelembagaan, (3) alternatif : pantai bungus, pantai nirwana, pantai pasir jambak. Maka dapat disimpulkan dari hasil nilai keseluruhan masing-masing alternatif objek wisata bahwa di Pantai Bungus (0,8633), Pantai Nirwana (0,0349) dan Pantai Pasir Jambak (0,1017). Maka Pantai yang lebih di prioritaskan pengembangan objek wisata yaitu Pantai Bungus dengan bobot (0,8633).
